This book was released on 2020 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ruthenium polypyridyl complexes (RPCs) are promising anticancer agents due to their robustness and tunability of their polypyridyl ligands. Their axial chirality generally allows for more selective binding to biological molecules. The ruthenium complexes [Ru(phen)3]Cl2 (RPC 1),[Ru(DIP)3]Cl2 (RPC 2), [(phen)2Ru(tatpp)]Cl2 (RPC 3), [(phen)2Ru(tatpp)Ru(phen)2]Cl4 (RPC 4), and [(phen)2Ru(dppz)]Cl2 (RPC 5) have all been investigated, and RPCs 2, 3, and 4 have shown lower micromolar cytotoxicity against malignant cell lines without irradiation. Here in we show that microtubules (MTs) may be the target of some RPCs in cells and all these RPCs 1-5 promote tubulin polymerization in vitro. How they interact with MTs is still yet to be discovered. We examined how the different enantiomers of RPC 2 and 3 affected the cytotoxicity, the cellular uptake, and the MT polymerization. Chapter 1 of this thesis reviews prior literature and discusses other metal complexes as well as RPCs that have anticancer potential for their cellular target and correlation to their structures. Chapters 2 and 3 presents how the stereochemistry of the RPCs in their chloride salt affects their ability to stabilize MTs in addition to entering the cell in the first place. Chapter 2 also presents evidence that MT stabilization by RPCs may not be simple due to electrostatic interactions. MT stabilization is done by comparing the in vitro polymerization of free tubulin with and without the presence of the microtubule stabilizing agent (MSA) as a factor of increased light scattering at 340 nm. Cellular uptake is done in the non-small cell lung carcinoma cell line, H358. The amount of ruthenium was analyzed using ICP-MS and the protein concentration using a bicinchoninic acid assay and UV-Vis spectrometry. Although there were no significant chiral differences in MT stabilization, there was a difference in cellular uptake of enantiopure RPC 2. Chapter 4 outlines the resolution of the RPCs by use of Na2[As2(+ or -)tartrate2] and Na2[Sb2(+ or -)tartrate2], as well discussing the optimization of the syntheses of Na2[Sb2(+ or -)tartrate2] and K2[Sb2(+ or -)tartrate2].
Download or read book Effect of Structure and Stereochemistry on Cytotoxicity of Ruthenium Polypyridyl Complexes written by Arthi Krishnan and published by . This book was released on 2007 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study showed some promising results which are listed below. The type of the bridging ligand attached to the metal center played a vital role in determining the potency of the drug, the longer tatpp ligand being more effective. The benefit of working with two metal centers as compared to one center was minimal; MP2+ and P4+ have similar IC50 values. Stereochemistry had a measurable effect on cytotoxicity; the Delta/DeltaDelta isomers were approximately twice more potent than the Λ/ΛΛ isomers. The stereochemistry around the dimeric complexes ought to be DeltaDelta for it work best, meso complexes (DeltaΛ) are equivalent in potency as the ΛΛ isomers. Complexes MP2+ and P4+ showed higher IC50 values in healthy cells and so they have a larger therapeutic window which can be very useful in designing new cancer therapy drugs.
