Titelbeschreibung

In view of their promising biological and pharmaceutical activities, natural product inspired and heterocyclic compounds have recently gained a reputation in the field of medicinal chemistry. Over the past decades, intensive research efforts have been ongoing to understand the synthesis, biochemistry and engineering involved in their preparation and action mechanisms. Several novel natural product derivatives, heterocyclic and other synthetic compounds, have been reported to have shown interesting biological activities including anticancer, antimicrobial, anti-inflammatory, anti-glycemic, anti-allergy and antiviral etc. Chemistry of Biologically Potent Natural Products and Synthetic Compounds provides up-to-date information on new developments and most recent medicinal applications of the natural products and derivatives, as well as the chemistry and synthesis of heterocyclic and other related compounds.

Back cover copy

Provides up-to-date information on new developments and most recent medicinal applications of the natural products containing heterocyclic and other related compounds.The increasing incidences of multidrug resistance toward conventional pharmaceuticals have increased the demand for the discovery and development of new drug candidates with novel action mechanisms. Natural products and their synthetic analogs have shown interesting preclinical and clinical results as pharmaceuticals and have recently gained considerable attention in modern medicinal chemistry and drug design.This book is organized into 13 important chapters that focus on the progress made by natural products and their synthetic analogs obtained directly from natural sources, as well as modified by synthesis/semi-synthesis procedures in medicinal chemistry as antiviral, anticancer, antibacterial, and anti-inflammatory agents. The various methods for enhancing the secondary metabolite concentration for efficient drug design are also described.AudienceThe book will be used extensively by research scholars, scientists and postgraduate students working in the areas of medical science, pharmacy, natural products and organic synthesis.
