Book Novel Strategies for Improving the Pharmacological Properties of Platinum acridine Anticancer Agents

Download or read book Novel Strategies for Improving the Pharmacological Properties of Platinum acridine Anticancer Agents written by Song Ding and published by . This book was released on 2015 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlike traditional cisplatin-type platinum-based anticancer drugs, platinum-acridine hybrid agents were designed as dual platinating/intercalating DNA-targeted cytotoxics, which are able to cause cancer cell death at low-nanomolar concentrations. Unfortunately, the preclinical development of these agents has been hampered by their severe systemic toxicity. The goal of this dissertation was to devise strategies that improve the drug-like properties of platinum-acridines and allow their safe delivery. To achieve this, several classical and newly developed synthetic methodologies have been used to generate functionally unique hybrid agents. Several model systems, whole-cell assays, and animal studies have been used in this dissertation to validate their design and demonstrate their utility as anticancer agents. A modular screening platform was developed, based on a platinum-mediated amine-to-nitrile addition reaction, for rapid identification of functionalized platinum-acridine agents. These pre-screening assays produced functionalized "warheads" while providing insight into structure–activity relationships (SAR). Using several library members, we set out to explore synthetic approaches to construct platinum-acridine-based conjugates. A chemically robust azide-modified platinum-acridine was selected to validate the feasibility of copper-mediated and copper-free click chemistry as platinum-compatible conjugation reactions. This chemistry was used to attach fluorescent molecules to detect platinum-acridines in cancer cells by confocal microscopy. Both fluorophore tagging prior to incubation with cells and post-labeling methods were explored. In addition, a hydroxyl-modified warhead was conjugated with endoxifen via a chemically stable carbamate bond to produce a highly active hybrid agent in estrogen receptor positive (ER+) breast cancer. In another study, lipophilic ester-based prodrugs of platinum–acridines were generated showing improved drug-like properties (e. g., partition coefficients, logD). Two distinct pathways by which the target compounds can be activated have been confirmed by LC-ESMS and/or NMR techniques: (i) a platinum-assisted, self-immolative ester cleavage in a low-chloride environment, and (ii) enzymatic cleavage by human carboxylesterase-2 (hCES-2). Highly efficient amide coupling reactions in platinum complexes were also developed. This modular approach can be used to assemble a diverse library of platinum-acridines containing other bioactive components, such as molecularly targeted therapies, targeted ligands, and chemosensitizers. Finally, liposomal encapsulation of platinum-acridine was achieved, and the formulations were evaluated in A549 lung cancer xenograft models in mice. Improved anticancer efficacy of one of the liposomal formulations compared with the free drug was observed in this assay. In conclusion, the research in this dissertation has laid the foundation for the future preclinical development of platinum-acridines as oncology drugs by devising new synthetic methodology and providing proof-of-concept data in clinically relevant models of cancer.

Book Novel Approaches for Controlling Target Selectivity and Pharmacological Properties of Platinum intercalator based Anticancer Agents

Download or read book Novel Approaches for Controlling Target Selectivity and Pharmacological Properties of Platinum intercalator based Anticancer Agents written by Amanda Jayne Pickard and published by . This book was released on 2014 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional DNA-targeted anticancer agents, such as platinum-based therapies, have been a mainstay in the treatment of aggressive solid malignancies in the clinical setting. Unfortunately, due to multifactorial drug resistance and systemic toxicity the clinical efficacy of these drugs is severely limited. Platinum–acridine hybrid agents have proven to overcome multifactorial drug resistance in some of the most aggressive forms of cancer, in particular non-small-cell lung cancer (NSCLC). The remaining challenges with this generation of anticancer agents revolve around overcoming the dose-limiting toxicities caused by indiscriminate chromatin damage (genotoxicity) in malignant and healthy cells and improving the unfavorable pharmacokinetics (PK) caused by the poor drug-like properties of these agents. The goal of this dissertation was to devise a structurally minimalistic approach by which platinum–acridines can be tuned to simultaneously achieve both of these goals. In particular, a design was desired that minimizes platinum adduct formation in the double-stranded portion of genomic DNA but enhances the reactivity with G-quadruplex DNA, a preclinically validated anticancer target. Density functional theory (DFT) calculations were used to study the reactivity of the monofunctional platinum moieties toward nucleobases in relevant target structures. Computational pre-screens were also used to identify DNA-targeted chromophores that show decreased basicity of the endocyclic nitrogen (proton affinities, [triangle]DG[subscript proton].) and an increased planar aromatic surface area to promote G-quadruplex binding. From these pre-screens, quinoline (Q1), acridine (A1), and three benz[c]acridines (B1, B2, B3) were selected and synthesized for a structure–activity relationship (SAR) study. Using microscale reactions, a modular library of 20 hybrid agents was assembled from the 5 chromophores and 4 platinum modules (P1–P4) and evaluated in two aggressive NSCLC cancer cell lines (NCI-H460, NCI-H520) using a cell proliferation assay. From the combinatorial pre-screen, two molecules of interest ("hits") emerged, P1-B1 and P1-B2, which both contained a core benz[c]acridine chromophore. In an extended panel of NSCLC cell lines (NCI-H522, NCI-1435, A549), P1-B1 maintained submicromolar IC50 values. In addition, when compared to the acridine prototype P1-A1, the new benz[c]acridine chromophore showed significantly decreased basicity (pK[subscript a(P1-B1)] = 7.6 vs. pK[subscript a(P1-A1)] = 9.4) (pH-dependent absorbance spectra). The combination of structural and electronic tuning achieved in derivative P1-B1 proved to have a major effect on the subcellular distribution of the hybrid agent and its ability to accumulate in cellular DNA and RNA (confocal fluorescence microscopy, inductively-coupled plasma mass spectrometry, ICP-MS). Although P1-A1 and P1-B1 undergo efficient trafficking from the lysosomes to the nucleus, the latter derivative did not show significant adduct formation in DNA after 6 h of incubation with NCI-H460 cells. All tested hybrids, P1-A1, P1-B1, and P1-B2, as well as their platinum-free carrier ligand modules A1, B1, and B2 were shown to interact favorably with relevant G-quadruplex forming sequences, including the human telomeric repeat and three sequences identified in the genes encoding ribosomal RNA (rRNA) (CD spectroscopy, highresolution mass spectrometry, HRMS). In particular, the benz[c]acridine derivative B1 appears to promote a highly specific interaction with the human telomeric repeat. To validate the approach pursued in this research, a dose escalation study was performed with the new "lead" compound P1-B1 in mice. When administered by intraperitoneal injection for five consecutive days, the new derivative proved to be significantly less toxic to the test animals than the prototype, P1-A1, resulting in an approximately 32-fold higher maximum tolerated dose (MTD). Together with the SAR established in this study, these results attest to the successful design strategy and encourage further preclinical development of P1-B1 and related molecules.

Book Unconventional Anticancer Metallodrugs and Strategies to Improve their Pharmacological Profile

Download or read book Unconventional Anticancer Metallodrugs and Strategies to Improve their Pharmacological Profile written by Maria Contel and published by MDPI. This book was released on 2019-10-01 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the past 40 years, metal-based drugs have been widely used for the treatment of cancer. Cisplatin and follow-up drugs carboplatin (ParaplatinTM) and oxaliplatin (EloxatinTM) have been the gold standard for metallodrugs in clinical settings as antineoplastic agents. While effective, these drugs (either alone or in combination therapy) have faced a number of clinical challenges resulting from their limited spectrum of activity, high toxicity leading to significant side effects, resistance, poor water solubility, low bioavailability and short circulating time. In the past 10 years, various unconventional non-platinum metal-based agents have emerged as a potential alternative for cancer treatment. These compounds are highly effective and selective in cancers resistant to cisplatin and other chemotherapeutic agents. Research in this area has recently exploded with a relevant number of patents and clinical trials, in addition to reports in scientific journals. Furthermore, in parallel to the synthesis of coordination and organometallic compounds comprising many different metals and unconventional platinum-based derivatives, researchers are focused on optimizing mechanistic and pharmacological features of promising drug candidates. This Special Issue aims to highlight the latest advances in anticancer metallodrugs with a focus on unconventional anticancer agents, as well as novel activation, targeting and delivery strategies aimed at improving their pharmacological profile.

Book Structure activity Relationships in Functionalized Platinum acridine Anticancer Agents

Download or read book Structure activity Relationships in Functionalized Platinum acridine Anticancer Agents written by Leigh Ann Graham and published by . This book was released on 2012 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since Rosenberg's serendipitous discovery of the cytotoxic properties of cisdiamminedichlor(id)oplatinum(II), better known as cisplatin, the development of new platinum-based chemotherapies with improved activity and reduced toxicity has become a pressing goal. Many second- and third-generation derivatives of cisplatin have been successful in decreasing toxicity, enhancing delivery, and showing a broader spectrum of antitumor activity. Recently, a dual platinating/intercalating DNA-targeted agent, [PtCl(en)(N-[acridin-9-ylamino)ethyl]-N-methylpropionamidine] dinitrate (25), has been reported that shows high activity in NCI-H460 non-small-cell-lung cancer (NSCLC) both in vitro and in vivo, but has proven to have high systemic toxicity (nephrotoxicity). In order to reduce the toxicity of this agent, two new methodologies were developed to reduce unwanted platinum interactions with sulfur-containing biomolecules such as glutathione. The first method was aimed at changing the chlor(id)o leaving group of the prototype (25) to a monodentate carboxylate. Although carboxylates in general, and monocarboxylates in particular, are more labile leaving groups than chloride, bulky groups incorporated in this leaving group may be successful in blocking the axial positions in associative substitution reactions. The ultimate goal of generating an analogue of 25 with monodentate carboxylates was not reached due to the tautomerization and N, N-chelation of the acridine chromophore, resulting in the formation of two new complexes that contain seven-membered N, N-chelates that were synthesized and studied for biological activity (28 and 29). These chelates do not undergo ligand substitution reactions with biological nucleophiles, such as nucleobase nitrogen and cysteine sulfur, and do not intercalate into DNA. This was demonstrated in model systems using NMR and UV-visible spectroscopies. Despite their inertness, in colorimetric cell proliferation assays complexes 28 and 29 do maintain micromolar activity in NCI-H460 lung cancer cells. The results are discussed in the context of potential DNA-mediated and DNA-independent cell kill mechanisms and the potential use of the chelates as prodrugs. The second project involved the synthesis of platinum-acridine prodrugs with hydrolysable carboxylic acid ester groups that would lead to the formation of N-O chelate complexes under physiological conditions. The synthesis of these complexes was achieved through the addition of the acridine ligand across the metal-activated triple bond of a nitrile that contained a cleavable ester group. The most active ester-modified derivatives and the unmodified parent compounds showed up to 6-fold higher activity in ovarian cancer (OVCAR-3) and breast cancer (MCF-7, MDA-MB-23) cell lines than cisplatin. An even more pronounced inhibition of cell proliferation at nanomolar concentrations was observed in pancreatic (PANC-1) and non-small cell lung cancer cells (NSCLC, NCI-H460) of 80- and 150-fold, respectively. Most importantly, introduction of the ester groups did not adversely affect the cytotoxic properties of the hybrids, which form the same DNA adducts as the parent compounds. In-line high-performance liquid chromatography-electrospray mass spectrometry (LC-MS) was used to demonstrate that the ester moieties in the newly synthesized compounds undergo platinum-mediated hydrolysis in a chloride concentration-dependent manner to form a chelated carboxylate form of the agent. This new ester-cleavage mechanism under physiological conditions could potentially provide a new opportunity for tumor-targeted therapy of platinumacridines through the self-immolative release of this family of cytotoxic agents.

Book Small Molecule DNA and RNA Binders

Download or read book Small Molecule DNA and RNA Binders written by Martine Demeunynck and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 754 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of molecules that selectively bind to nucleic acids has provided many details about DNA and RNA recognition. The range of such substances, such as metal complexes, peptides, oligonucleotides and a wide array of synthetic organic compounds, is as manifold as the functions of nucleic acids. Nucleic acid recognition sequences are often found in the major or minor groove of a double strand, while other typical interactions include intercalation between base pairs or the formation of triple or quadruple helices. One example of a binding mode that has recently been proposed is end stacking on such complex structures as the telomere tetraplex. In this comprehensive book, internationally recognized experts describe in detail the important aspects of nucleic acid binding, and in so doing present impressive approaches to drug design. Since typical substances may be created naturally or synthetically, emphasis is placed on natural products, chemical synthesis, the use of combinatorial libraries, and structural characterization. The whole is rounded off by contributions on molecular modeling, as well as investigations into the way in which any given drug interacts with its nucleic acid recognition site.

Download or read book Cisplatin written by Bernhard Lippert and published by John Wiley & Sons. This book was released on 1999 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: 30 years after its discovery as an antitumor agent, cisplatin represents today one of the most successful drugs in chemotherapy. This book is intended to reminisce this event, to take inventory, and to point out new lines of development in this field. Divided in 6 sections and 22 chapters, the book provides an up-to-date account on topics such as - the chemistry and biochemistry of cisplatin, - the clinical status of Pt anticancer drugs, - the impact of cisplatin on inorganic and coordination chemistry, - new developments in drug design, testing and delivery. It also includes a chapter describing the historical development of the discovery of cisplatin. The ultimate question - How does cisplatin kill a cell? - is yet to be answered, but there are now new links suggesting how Pt binding to DNA may trigger a cascade of cellular reactions that eventually result in apoptosis. p53 and a series of damage recognition proteins of the HMG-domain family appear to be involved. The book addresses the problem of mutagenicity of Pt drugs and raises the question of the possible relevance of the minor DNA adducts, e.g. of interstrand cross-links, and the possible use of trans-(NH3)2Pt(II)-modified oligonucleotides in antisense and antigene strategies. Our present understanding of reactions of cisplatin with DNA is based upon numerous model studies (from isolated model nucleobases to short DNA fragments) and application of a large body of spectroscopic and other physico-chemical techniques. Thanks to these efforts there is presently no other metal ion whose reactions with nucleic acids are better understood than Pt. In a series of chapters, basic studies on the interactions of Pt electrophiles with nucleobases, oligonucleotides, DNA, amino acids, peptides and proteins are reported, which use, among others, sophisticated NMR techniques or X-ray crystallography, to get remarkable understanding of details on such reactions. Reactivity of cisplatin, once bound to DNA and formerly believed to be inert enough to stay, is an emerging phenomenon. It has (not yet) widely been studied but is potentially extremely important. Medicinal bioinorganic chemistry - the role of metal compounds in medicine - has received an enormous boost from cisplatin, and so has bioinorganic chemistry as a whole. There is hardly a better example than cisplatin to demonstrate what bioinorganic chemistry is all about: The marriage between classic inorganic (coordination) chemistry and the other life sciences - medicine, pharmacy, biology, biochemistry. Cisplatin has left its mark also on areas that are generally considered largely inorganic. The subject of mixed-valance Pt compounds is an example: From the sleeping beauty it made its way to the headlines of scientific journals, thanks to a class of novel Pt antitumor agents, the so-called "platinum pyrimidine blues". In the aftermath diplatinum (III) compounds were recognized and studies in large numbers, and now an organometalic chemistry of these diplatinum (III) species is beginning to emerge. The final section of the book is concerned with new developments such as novel di- and trinuclear Pt(II) drugs with DNA binding properties different from those of cisplatin, with orally active Pt(IV) drugs which are presently in clinical studies, and with attempts to modify combinatorial chemistry in such a way that it may become applicable to fast screening of Pt antitumor drugs. The potential of including computational methods in solving questions of Pt-DNA interactions is critically dealt with in the concluding chapter.
