摘要
胃肠道间质瘤(GIST)是不寻常的癌症,在胃肠道壁的特化细胞中发展。涉及单药,组合和快速互补抑制剂循环的各种策略现在正用于控制此类肿瘤。基于有希望的早期临床试验经验,某些新型KIT和PDGFRA酪氨酸激酶抑制剂已经显示出先进的临床发展。对酪氨酸激酶抑制剂的耐药性带来了巨大的困难,患者现在需要额外的治疗选择。本文描述并讨论了过去五年(2016-2020年)使用虚拟筛选和对接方法开发新型c-KIT激酶抑制剂的情况。计算技术可用于补充实验研究,以确定用于治疗用途的新候选分子。分子建模策略允许分析化合物有效结合c-KIT所必需的特性。通过这样的分析,可以发现和设计针对在肿瘤发展中起关键作用的癌症相关蛋白质(包括突变菌株)的新型抑制剂。对接在检测负责配体识别的关键残基方面显示出潜力,并且非常有助于了解活性位点中的相互作用,这些相互作用可用于开发新的化合物/类抗癌药物并帮助数百万癌症患者。
关键词: 新型c-Kit抑制剂,药物设计,分子对接,GIST,PDGFRA,GA。
