基于VHSE(Principal component score vector of hydrophobic,steric,and electronic properties)结构表征方法,采用支持向量机结合遗传算法变量筛选技术,分别建立B*5701和B*5801多肽亲和活性的分类预测模型,其最优线性模型内部验证的灵敏度(Sensitivity,Sen)、特异性(Specificity,Spe)、接受者操作特征曲线下面积(Area under receiver operating characteristics curve,AUC)和马休斯相关系数(Matthews coefficient of correlation,MCC)分别为77.29%、93.99%、93.02%、67.65% (B*5701)和78.08%、89.62%、88.34%、64.73% (B*5801);外部验证的Sen、Spe、AUC和MCC分别为80.02%、94.53%、94.62%、72.09% (B*5701)和77.43%、90.79%、87.98%、66.20% (B*5801).依据最优模型,分别对B*5701和B*5801配体的亲和特性进行了细致的比较和分析,研究结果可为Abacavir的HLA-B*5701限制性药物毒副作用(Serious Adverse Drug Reactions,SADR)机理研究提供重要的参考依据.
