Abstract:

通过对3种吩噻嗪类药物进行分析,探讨3种吩噻嗪类药物潜在抗肿瘤的作用机制.首先通过预测能够与氯丙嗪、氟奋乃静和三氟拉嗪相互作用的靶蛋白,然后对3种药物的靶蛋白取交集,对交集蛋白进行细胞信号通路富集和相关疾病富集,提取属于肿瘤的富集类,进而通过蛋白相互作用网络调控分析,阐明这些靶蛋白在肿瘤中的作用机制,从而明确吩噻嗪类药物潜在抗肿瘤的作用机制.细胞信号通路富集和相关疾病富集结果均显示,得分最高的类别为肿瘤,在属于肿瘤类别的靶蛋白中,包含有Wnt,MAPK,维甲酸受体等信号通路成员.并且与靶蛋白相关的细胞信号级联传递过程中,MAPK8能够间接作用于靶蛋白CDK2,IGF1R,GSK3B,RARA,FGFR2和MAPK10进而影响肿瘤细胞的分裂与增殖.因此,吩噻嗪类药物可能具有潜在的抗肿瘤作用,其与肿瘤相关的靶蛋白在细胞信号级联转导过程中发挥着关键作用.
