This study explored the potential of a series of PZM21 analogues for pain treatment. Specifically, the hydroxyphenyl ring of PZM21 was replaced with a naphthyl ring, the thienyl ring was substituted with either a phenyl ring or furan rings, and the essential dimethylamine and urea groups were retained. These compounds aimed to enhance safety and minimize the adverse effects associated with opioid drugs
这项研究探讨了一系列 PZM21 类似物治疗疼痛的潜力。具体而言,PZM21的羟基苯环被萘环取代,噻吩环被苯环或呋喃环取代,并且保留必要的二甲胺和脲基团。这些化合物旨在提高安全性并尽量减少与阿片类药物相关的副作用。研究结果表明,化合物 6a 在低纳摩尔浓度下不会诱导 β-抑制蛋白募集,但在已建立的小鼠模型中表现出显着的镇痛作用。与吗啡相比,6a 在缓解呼吸抑制和最大限度地减少身体依赖性方面显示出优势。分子对接研究强调了 D147 氨基酸残基在 6a 镇痛机制中的关键作用。因此,6a 是开发更安全的阿片类镇痛药的有力候选者,值得进一步关注。
