replacement of substituted benzyl groups by an indan rigid moiety in a previously described N-indazole- N'-benzyl urea series led to a number of TRPV1 antagonists with significantly increased in vitro potency and enhanced drug-like properties. Extensive evaluation of pharmacological, pharmacokinetic, and toxicological properties of synthesized analogs resulted in identification of ( R)-7 ( ABT-102)
Vanilloid受体TRPV1是一个阳离子通道,可被多种有害刺激物(包括辣椒素,酸和热)激活。几家制药公司正在研究选择性拮抗剂对TRPV1激活的阻断作用,以寻找用于疼痛治疗的新型药物。在这里我们报告说,在先前描述的N-吲唑-N'-苄基脲系列中,茚满刚性部分取代了取代的苄基,导致许多TRPV1拮抗剂具有显着提高的体外效力和增强的类药物特性。对合成类似物的药理,药代动力学和毒理学性质进行了广泛的评估,结果鉴定出(R)-7(ABT-102)。(R)-7的镇痛活性和类药物特性均支持其在临床疼痛试验中的发展。
