耶鲁大学的研究人员测试了一种新的化合物,能够抑制HIV,保护免疫细胞,并在一个星期内保持有效。研究人员说,在动物实验中,这种化合物被证明是一种很有希望的新型候选药物,可以增强目前的HIV治疗方案,而不会增加毒副作用。

这一发现建立在Karen S. Anderson和William L. Jorgensen的工作基础之上,他们使用基于计算和结构的设计方法来开发一类针对HIV复制所必需的病毒蛋白的化合物。研究人员对这一类化合物进行了改进,以提高效力,降低毒性,改善药物性质,以便确定一个有前途的临床前候选药物。与耶鲁大学的Priti Kumar实验室合作,在移植人血细胞的小鼠身上检测候选药物并感染HIV。

在人性化小鼠中,该化合物实现了HIV治疗的关键目标:将病毒抑制到血液中检测不到的水平;它保护了病毒感染免疫细胞;研究人员表示,它与已获批准的艾滋病药物协同作用。

此外,研究人员与耶鲁药物递送专家马克·萨尔兹曼(Mark Saltzman)及其实验室合作,研究人员发现单剂量化合物(以长效纳米颗粒形式)的效果持续了近一个月。

安德森说,虽然还需要进一步的检测,但该化合物有改善艾滋病毒治疗的潜力,全世界有3700万人感染艾滋病毒。 “我们的候选药物与目前所有类型的HIV药物协同作用,以及一些临床试验中正在测试的药物,它们增强了它们的效力,可能是更好的联合用药。
