only potent CB1R activity but also a desired tPSA value over 90 Å2, a threshold considered to possess a low probability to cross BBB, leading to the identification of compound 4 (B/P = 1/64) as a peripherally restricted CB1R antagonist. Apart from its significant weight-loss efficacy in DIO mice, compound 4 also displays 163 clean off-target profiles and is currently under development for treating obesity
经过广泛的合成努力,我们发现可以通过衍生具有不同电负性基团的化合物3(B / P = 1/33)的吡唑环上的C-4烷基链来生成许多结构多样的生物等排体。尤其是混合物中加入磺酰胺或硫酰胺基团时,得到的化合物显示出不仅有效的CB1R活性,而且还期望的tPSA值超过90埃2,认为具有低概率穿过BBB的阈值,从而导致化合物的鉴定4(B / P = 1/64)作为外围受限制的CB1R拮抗剂。除了在DIO小鼠中具有显着的减肥功效外,化合物4 它还显示了163个干净的脱靶曲线,目前正在开发中,用于治疗肥胖症和相关的代谢综合征。
