Isosteric replacement of the phenolic hydroxyl group in potent vanilloid receptor (VR1) agonists with the alkylsulfonamido group provides a series of compounds which are effective antagonists to the action of the capsaicin on rat VR1 heterologously expressed in Chinese hamster ovary (CHO) cells. In particular, compound 61, N-[2-(3,4-dimethylbenzyl)-3-pivaloyloxypropyl]-N'-[3-fluoro-4-(methylsulfonylamin
用烷基磺酰胺基对强效香草醛受体(VR1)激动剂中的酚羟基进行等位置换,提供了一系列化合物,可有效拮抗辣椒素对在中国仓鼠卵巢(CHO)细胞中异源表达的大鼠VR1的作用。特别是,化合物61 N- [2-(3,4-二甲基苄基)-3-新戊酰氧基丙基] -N'-[3-氟-4-(甲基磺酰氨基邻氨基)苄基]硫脲是辣椒素的完全拮抗剂。 K(i)值为7.8 nM(相比之下,卡塞平为520 nM,5-iodoRTX为4 nM),并且在小鼠中显示出出色的镇痛活性。
