由于体内疗效差而导致的失败是新化疗药物开发期间消耗的主要原因。铅优化程序,在他们的追求疗效只集中在提高药物靶结合的亲和力是有缺陷的,因为这种方法忽略了在体内发生的药物浓度的波动。相反,还必须考虑药物-靶点复合物的寿命,因为药物只有在与靶点结合时才起作用。因此,为了改善药物的体外和体内活性之间的相关性,必须将药物-靶标停留时间的测量纳入药物发现过程中。
Failure due to poor in vivo efficacy is a primary contributor to attrition during the development of new chemotherapeutics. Lead optimization programs that in their quest for efficacy focus solely on improving the affinity of drug-target binding are flawed, since this approach ignores the fluctuations in drug concentration that occur in vivo. Instead the lifetime of the drug-target complex must also be considered, since drugs only act when they are bound to their targets. Consequently, to improve the correlation between the in vitro and in vivo activity of drugs, measurements of drug-target residence time must be incorporated into the drug discovery process.
