and had almost no hyperthermia side-effect. Furthermore, pharmacokinetic studies revealed that compound 6g had a superior oral exposure after oral administration in rats. To understand its binding interactions with the receptor, the docking study of 6g was performed in rTRPV1 model and showed an excellent fit to the binding site. On the basis of its superior profiles, 6g could be considered as the lead
本文报道的是在以2,3,4,9-四氢-1 H-吡啶并[3,4- b ]吲哚为A区且三唑为B-的情况下构建的一类TRPV1拮抗剂的设计,合成和药理学评估。地区。SAR分析表明,与相应的二氢吲哚类似物相比,2,3,4,9-四氢-1 H-吡啶并[3,4- b ]吲哚类似物显示出对辣椒素激活hTRPV1的优异拮抗作用,并显示出更好的效价。该设计的优化导致最终鉴定出2-((1-(2-(三氟甲基)苯基)-1 H -1,2,3-三唑-4-基)甲基)-2,3,4,9 -tetrahydro-1 H -pyrido [3,4- b ]吲哚(6克),一种有效的TRPV1拮抗剂。在体外,使用表达重组人TRPV1通道的细胞,6g表现出被辣椒素激活的强烈拮抗作用(IC 50 = 0.075μM),并且仅部分阻断了TRPV1的酸激活。在体内,6g在辣椒素诱导和热诱导的疼痛模型中显示出良好的疗效,并且几乎没有热疗的副
