A series of structurally novel aryl ureas was derived from optimization of the HTS lead as selective histamine H3 receptor (H3R) antagonists. The SAR was explored and the data obtained set up the starting point and foundation for further optimization. The most potent tool compounds, as exemplified by compounds 2l, 5b, 5d, and 5e, displayed antagonism potencies in the subnanomolar range in in vitro
通过优化HTS铅作为选择性组胺H 3受体(H 3 R)拮抗剂,获得了一系列结构新颖的芳基脲。探索了SAR,获得的数据为进一步优化奠定了起点和基础。如化合物2l,5b,5d和5e所示,最有效的工具化合物在体外人-H 3 R FLIPR分析和恒河猴H 3 R结合分析中显示出亚纳摩尔范围的拮抗力。
