Available in PDF, EPUB and Kindle. Book excerpt: Steroids are a large group of compounds whose structure is based on a 17-carbon skeleton, with a specific cyclopentanoperhydrophenanthrene ring system. Natural steroids have been fine-tuned through evolution to build membranes; act as chemical messengers that regulate metabolic, immune and reproductive functions in animals and stimulate the growth of, or otherwise protect, animal organisms. The steroid core represents a suitable motive for structural modifications. Therefore, a large group of semi-synthetic steroid derivatives have occupied the attention of synthetic chemists as well as medicinal chemists due to their potential biological activity, including anticancer, antibacterial, anti-inflammatory and (anti)hormonal activities. This Reprint of the Special Issue of Molecules titled "Steroid Compounds with Potential Biological Activity" is dedicated to both experimental and theoretical studies on steroid chemistry, structural biology, biosynthesis, metabolism, and pharmacology. The Issue focuses on the isolation and synthesis of steroid compounds, diverse in origin, as well as their structural characterization and identification. Published articles and reviews relate to in vitro and in silico studies of the pharmacological properties, molecular biology, biochemistry and structural biology of steroids.

This book was released on 2023-07-18 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steroids are an important class of biomolecules with diverse roles and functions. Besides being important as structural and signaling molecules, these molecules hold promise against numerous disorders, including cardiovascular conditions, cancer, inflammation, and autoimmune disorders. Many investigations have demonstrated that steroidal frameworks may provide lipid solubility, receptor selectivity, or membrane binding properties to non-steroidal pharmacophores. However, the therapeutic use of steroids can be dangerous when they're used incorrectly. Additionally, misconceptions about steroids among athletes or recreational users can lead to steroid abuse and poor health outcomes. Steroids and their MedicinalPotential discusses the classification, distribution, biosynthesis, chemical synthesis, and semi-synthesis of different steroids. The medicinal potential of each class is exhaustively discussed in different chapters. The latest advances and developments in steroid-based drug discovery are also discussed thoroughly. The book aims to address general questions and concerns about steroids, providing readers with a useful resource on the subject.

Download or read book Intestinal Lipid Metabolism written by Charles M. Mansbach and published by Springer Science & Business Media. This book was released on 2000-11-30 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was stimulated by the enthusiasm shown by attendees at the meetings in Saxon River, VT, sponsored by the Federation ofAmerican Societies for Experimental Biology (FASEB), on the subject of the intestinal processing of lipids. When these meetings were first started in 1990, the original organizers, two of whom are editors ofthis volume (CMM and PT), had two major goals. The first was to bring together a diverse group ofinvestiga tors who had the common goal of gaining a better understanding of how the intestine ab sorbs lipids. The second was to stimulate the interest of younger individuals whom we wished to recruit into what we believed was an exciting and fruitful area ofresearch. Since that time, the field has opened up considerably with new questions being asked and new an swers obtained, suggesting that our original goals for the meetings were being met. In the same spirit, it occurred to us that there has not been a recentbook that draws to gethermuch ofthe informationavailableconcerninghow the intestineprocesses lipids. This book is intended to reach investigators with an interest in this area and their pre- and post doctoral students. The chapters are written by individuals who have a long-term interest in the areas about which they write, and many have been speakers at the subsequent FASEB conferences that have followed on the first.
