Methoxycarbonyl-1-phenyl-2-cyclopropylmethyl based derivatives cis-(+)-1a [cis-(+)-MR200], cis-(−)-1a [cis-(−)-MR201], and trans-(±)-1a [trans-(±)-MR204], have been identified as new potent sigma (σ) receptor ligands. In the present paper, novel enantiomerically pure analogues were synthesized and optimized for their σ receptor affinity and selectivity. Docking studies rationalized the results obtained
基于甲氧羰基-1-苯基-2-环丙基甲基的衍生物cis -(+)- 1a [ cis -(+)-MR200],cis -(-)- 1a [ cis -(-)-MR201]和反式-(± ) - 1A [反式- (±)-MR204],已被确定为新的有效西格玛(σ)受体配体。在本文中,合成了新颖的对映体纯类似物,并针对其σ受体亲和力和选择性进行了优化。对接研究使在放射性配体结合测定中获得的结果合理化。通过对前体反式-(+)- 5a作为樟脑磺酰基衍生物的X射线分析明确建立了绝对立体化学9。最有前途的化合物反式((+)- 1d)在超过15种受体上显示出显着的选择性,并在人血浆中具有良好的化学和酶稳定性。体内评价证明该反式- (+) - 1D,而相比之下,反式- ( - ) - 1D,顺式- (+) - 1D,或顺式- ( - ) - 1D,其表现为σ 1拮抗剂,表现出一个σ 1激动剂曲线。这些数据清楚地表明,化合物反式-
