4-dichlorophenyl)-5-arylpyrazoles strictly related to rimonabant, but with the hydrazide/amide group shifted from position 3 to position 4 of the pyrazole scaffold. The synthesized compounds were evaluated in vitro for their affinity on human CB(1) and CB(2) (cannabinoid type-2) receptors. Computational studies, performed both in the design step and after biological assays, contributed to rationalize the obtained
在1型大麻素(CB(1))受体拮抗剂中,围绕利莫那班(Acomplia)的1,5-二芳基吡唑骨架开发的那些拮抗剂(对Acomplia进行了最广泛的研究。近年来,有关该主题的许多SAR和QSAR报告已经发表,着眼于N1和C5芳基官能团的取代和取向以及3-羧酰胺位置的取代基在这种情况下,我们的研究目的是设计和合成一组1-(2,4-二氯苯基) -5-芳基吡唑与利莫那班严格相关,但酰肼/酰胺基团从吡唑支架的3位转移到4位。合成后的化合物在体外对人CB(1)和CB(2)的亲和力进行了评估(大麻素2型受体)在设计步骤和生物学分析后均进行了计算研究,在拮抗剂和人类CB(1)受体之间的特定分子相互作用方面,有助于合理化所获得的结果。
