Bioactive Heterocycles III

Bioactive Heterocycles III provides readers with a comprehensive overview of the most recent breakthroughs in the ?eld of heterocycles. This volume contains 8 chapters written by experts in their respective ?elds from all over the world. The chapters summarize years of extensive research in each area andprovideinsightinthenewthemesofnaturalproductresearch.Manyofthe contributors illustrate their laboratory experiences. Its obvious that readers will gain exciting and essential information fromthe volume. In the ?rst chapter Kayser et al. describe the chemistry biosynthesis and biological activities of artemisinin one of the most promising antimalarial molecules and its related natural peroxides. They present new strategies of producing artemisinin that utilize fascinating technologies. as Additionally thepharmacokineticpro?leandthedevelopmentofnewdrugdeliverysystems onPlasmodium infected erythrocytesare presented . Khan describes some aspects of sugar-derived heterocycles and their p- cursors which are utilized as the inhibitors against glycogen phosphorylases (GPs) and are responsible for the release of mono-glucose from poly-glucose (glycogen) in the second chapter. The inhibitors of GP could help to stop or slowdownglycogenolysisaswellasglucoseproduction.Ultimately thewhole processwill result in the recovery fromdiabetes of NIDDMpatients. In his contribution Verma studies quantitative structure-activityrelati- ship (QSAR) and proposes several interesting QSAR models of heterocyclic molecules having cytotoxicactivities against different cancer cell lines which couldin turn clarify the chemical-biologicalinteractions ofsuch compounds. Alamgir et al. in the fourth chapter review the recent progress of the synthesis reactivity and biological activities of benzimidazoles. Additionally they describe several new techniques and procedures for the synthesis of the same scaffold.
