New antihistaminic piperidine derivatives of general structural formula I are prepared by reacting 4-piperidinealkylamines with carboxylic acids or their active derivatives, such as lower-alkyl esters or the acid chlorides.
The obtained new piperidine carboxamide compounds show potent antihistaminic activity as specific antagonists of histamine H1-receptors.
通过 4-哌啶烷基胺与羧酸或其活性衍生物(如低级烷基酯或酸氯化物)反应,制备出结构通式 I 的新型抗组胺哌啶衍生物。
所获得的新哌啶甲酰胺化合物作为组胺 H1 受体的特异性拮抗剂,显示出强大的抗组胺活性。
Structure-activity relationship study of tryptophan-based butyrylcholinesterase inhibitors
A series of tryptophan-based selective nanomolar butyrylcholinesterase (BChE) inhibitors was designed and synthesized. Compounds were optimized in terms of potency, selectivity, and synthetic accessibility. The crystal structure of the inhibitor 18 in complex with BChE revealed the molecular basis for its low nanomolar inhibition (IC50 = 2.8 nM). The favourable in vitro results enabled a first-in-animal
