hylsulfonylamino)benzyl] thiourea (2) was a high affinity antagonist of the vanilloid receptor with a binding affinity of K(i)=63 nM and an antagonism of K(i)=53.9 nM in rat VR1 heterologously expressed in Chinese hamster ovary (CHO) cells (Mol. Pharmacol. 2002, 62, 947-956). In an effort to further improve binding affinity and antagonistic potency, we have modified the C-region of the lead 4-t-butylbenzyl
我们最近报道,N-(4-叔丁基苄基)-N'-[4-(甲基磺酰基氨基)苄基]硫脲(2)是香草素受体的高亲和力拮抗剂,结合亲和力为K(i)= 63 nM和在中国仓鼠卵巢(CHO)细胞中异源表达的大鼠VR1中K(i)= 53.9 nM的拮抗作用(Mol。Pharmacol。2002,62,947-956)。为了进一步提高结合亲和力和拮抗力,我们用多种替代物(例如芳烷基,烷基,4-炔基苄基,茚满基,3,3-二芳基丙基)修饰了4-叔丁基苄基铅的C区。 4-烷氧基苄基,4-取代的哌嗪和哌啶。亲脂性替代物,芳基烷基和烷基,在结合亲和力和拮抗力上适度降低;具有杂原子的基团导致急剧减少。
