  CCR5 Antagonists as Anti-HIV-1 Agents. 1. Synthesis and Biological Evaluation of 5-Oxopyrrolidine-3-carboxamide Derivatives

  摘要：

  一种新型的铅化合物N-{3-[4-(4-氟苯甲酰)piperidin-1-基]丙基}-1-甲基-5-氧代-N-苯基吡咯烷-3-羧酰胺（1）通过高通量筛选与[125I]RANTES和CCR5表达的CHO细胞被鉴定为CCR5拮抗剂。化合物1的IC50值为1.9 μM。为了提高化合物1的结合亲和力，合成了一系列5-氧代吡咯烷-3-羧酰胺。向中心苯环引入3,4-二氯取代基（10i，IC50=0.057 μM；11b，IC50=0.050 μM）或用1-苄基取代5-氧代吡咯烷部分的1-甲基基团（12e，IC50=0.038 μM）被发现有效提高了对CCR5的亲和力。化合物10i、11b和12e也分别以0.44、0.19和0.49 μM的IC50值抑制了CCR5使用的HIV-1包膜介导的膜融合。

  Inhibition of noroviruses by piperazine derivatives

  摘要：

  There is currently an unmet need for the development of small-molecule therapeutics for norovirus infection. The piperazine scaffold, a privileged structure embodied in many pharmacological agents, was used to synthesize an array of structurally-diverse derivatives which were screened for anti-norovius activity in a cell-based replicon system. The studies described herein demonstrate for the first time that functionalized piperazine derivatives possess anti-norovirus activity. Furthermore, these studies have led to the identification of two promising compounds (6a and 9I) that can be used as a launching pad for the optimization of potency, cytotoxicity, and drug-like characteristics.

  processes such as stress responses, appetite control, and motivation for reward. To date, pharmacological studies of RXFP3 have been limited to peptide ligands. In this study, we report the discovery of the first small-molecule antagonists of RXFP3 through a high-throughput screening campaign. Focused structure–activity relationship studies of the hit compound resulted in RLX-33 (33) that was able to
