摘要

We recently reported that N-(4-t-butylbenzyl)-N′-[4-(methylsulfonylamino) benzyl] thiourea (2) was a high affinity antagonist of the vanilloid receptor with a binding affinity of Ki= 63 nM and an antagonism of Ki= 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- ...
