ulfonamidophenyl)propanamides were investigated for hTRPV1 antagonism. The analysis indicated that the phenyl C-region derivatives exhibited better antagonism than those of the corresponding pyridine surrogates for most of the series examined. Among the phenyl C-region derivatives, the two best compounds 43 and 44S antagonized capsaicin selectively relative to their antagonism of other activators and
研究了一系列2-(3-氟-4-甲基磺酰胺基苯基)丙酰胺的2-取代的4-(三氟甲基)苄基C区类似物对hTRPV1的拮抗作用。分析表明,对于大多数所考察的系列,苯基C-区衍生物表现出比相应的吡啶替代物更好的拮抗作用。在苯基C区衍生物中,两种最佳化合物43和44S相对于它们与其他活化剂的拮抗作用选择性地拮抗辣椒素,并且在K(i(CAP))= 0.3 nM时显示出优异的效力。这两种化合物阻断了辣椒素诱导的体温过低,与TRPV1作为其作用部位相一致,并且在没有热疗的神经性疼痛模型中证明了有希望的镇痛活性。
