Structure-Activity Relationship Studies Of Synthetic Cathinones And Related Agents, Rachel A. Davies
Structure-Activity Relationship Studies Of Synthetic Cathinones And Related Agents, Rachel A. Davies
Theses and Dissertations
Synthetic cathinones and related agents represent an international drug abuse problem, and at the same time an important class of clinically useful compounds. Structure-activity relationship studies are needed to elucidate molecular features underlying the pharmacology of these agents. Illicit methcathinone (i.e., MCAT), the prototype of the synthetic cathinone class, exists as a racemic mixture. Though the differences in potency and target selectivity between the positional and optical isomers of synthetic cathinones and related agents have been demonstrated to have important implications for abuse and therapeutic potential, the two MCAT isomers have never been directly compared at their molecular targets: the …
Elaboration And Design Of Α7 Nachr Negative Allosteric Modulators, Osama I. Alwassil
Elaboration And Design Of Α7 Nachr Negative Allosteric Modulators, Osama I. Alwassil
Theses and Dissertations
α7 Neuronal nicotinic acetylcholine receptors are one of two major classes of receptors responsible for cholinergic neurotransmission in the central nervous system. The existence of α7 neuronal nAChRs in different regions of the nervous system suggests their involvement in certain essential physiological functions as well as in disorders such as Alzheimer’s disease (AD), drug dependence, and depression. This project was aimed toward the discovery and development of small–molecule arylguanidines that modulate α7 nAChR function with improved subtype-selectivity through an allosteric approach. Identifying the required structural features of these small molecules allowed optimization of their negative allosteric modulator (NAM) actions at …
