中文摘要
目的通过药效团和分子对接方式设计WEE1抑制剂。方法使用Discovery Studio 3.1建立WEE1蛋白小分子共晶复合物药效团,并利用活性、非活性化合物验证药效团的识别能力,筛选出最佳药效团模型。用筛选出的最佳药效团模型筛选化合物库,然后,分子对接进一步筛选出有效的先导化合物。结果根据验证结果筛选出区分活性和非活性化合物能力强的药效团模型ADDHHP,并用于小分子库筛选;通过分子对接研究,发现化合物含有磺胺基和氨基,与氨基酸残基有较好的亲和力,且含有氢键数目多。结论根据药效团和分子对接结果所得的化合物有助于WEE1抑制剂分子的设计、改构、并为发现治疗癌症的强有力的先导化合物提供了指导。
