提高药物的选择性作用是当前药物设计的重要问题之一。药物的选择性作用可以分为对病原体和宿主的选择性作用和对体内各种功能的选择性作用。对于治疗由病原体所致的各种疾病的药物,希望它对病原体如细菌、病毒、原虫、寄生虫和癌细胞等有很强的杀灭作用,而对宿主则没有或只有很微弱的毒副作用。对于调节或恢复体内各种机能的药物,则希望它只对
To improve the selective effect of drugs is one of the important problems in current drug design. Selective effects of drugs can be divided into the selective role of pathogens and hosts and the selective function of various functions in the body. For the treatment of various diseases caused by pathogens, it is hoped that it will have a strong killing effect on pathogens such as bacteria, viruses, protozoa, parasites, cancer cells and the like without any or only very little toxic side effects on the host .
