The structural modifications on the B-region of the potent and high affinity vanilloid receptor (VR1) lead ligand N-(3-acyloxy-2-benzylpropyl)-N(')-[4-(methylsulfonylamino)benzyl]thiourea were investigated by the replacement of the thiourea with diverse isosteric functional groups. Structure-activity analysis indicated that the A-region in this series was the primary factor in determining the agonistic/antagonistic
研究了强效和高亲和力类香草醇受体(VR1)铅配体N-(3-酰氧基-2-苄基丙基)-N(')-[4-(甲基磺酰基氨基)苄基]硫脲在B区的结构修饰。用不同的等排官能团取代硫脲。结构活性分析表明,该系列中的A区是决定激动/拮抗活性的主要因素,而与B区无关。与母体硫脲类似物相比,N(C)-羟基硫脲类似物(12、13)在乙酸扭曲试验中显示出出色的镇痛活性。
