Abstract

Title compds. I [wherein R1 = H; R2 = (un)substituted benzyl or 2-phenylethyl; R3 = H, halo or alkoxy; R4 = (CH2)nNH; n = 0-3; R5 = O or S; R6 = NHCH2; R7 = t-Bu or CF3] were prepd. as vanilloid TRPV1 receptor antagonists. For instance, thiourea II was synthesized in 42% yield by nucleophilic addn. of 4-tert-butylbenzyl isothiocyanate with the corresponding sulfamoylaniline (prepn. given). II was found to inhibit TRPV1-dependent responses with an affinity that was significantly greater than that of the classic TRPV1 receptor antagonist, capsazepine, in both in vitro and in vivo studies. Therefore, I can be used for the prepn. of medicaments for the treatment of inflammatory states.
