预防药物相互作用和减少与药物有关的死亡率要求更清洁和更昂贵的药物。在过去的10年里,将新药推向市场的成本急剧增加,发现后活动(临床前和临床)成本占了大部分支出。随着新药候选药物在发现后评估阶段所经历的审查越来越多,发现提供更高质量的候选药物的压力越来越大。考虑到早期临床阶段的化合物损耗通常可归因于代谢责任,最近人们对在药物设计发现阶段实施代谢稳定性/责任的预测措施非常感兴趣。要解决这个问题,就必须了解细胞色素P450(CYP)酶的基本功能和结构。最近,各种细胞色素P450酶的结构的实验信息,I相代谢的主要贡献者,已经变得容易获得。这一点,再加上可用的实验信息的底物特异性,导致了许多计算模型(大分子,药效团,和结构活性)的合理化和预测的生物学责任的发展。本章对这些模式进行了全面的审查。
Preventing drug-drug interactions and reducing drug-related mortalities dictate cleaner and costlier medicines. The cost to bring a new drug to market has increased dramatically over the last 10 years, with post-discovery activities (preclinical and clinical) costs representing the majority of the spend. With the ever-increasing scrutiny that new drug candidates undergo in the post-discovery assessment phases, there is increasing pressure on discovery to deliver higher-quality drug candidates. Given that compound attrition in the early clinical stages can often be attributed to metabolic liabilities, it has been of great interest lately to implement predictive measures of metabolic stability/ liability in the drug design stage of discovery. The solution to this issue is wrapped in understanding the basic of the cytochrome P450 (CYP) enzymes functions and structures. Recently, experimental information on the structure of a variety of cytochrome P450 enzymes, major contributors to phase I metabolism, has become readily available. This, coupled with the availability of experimental information on substrate specificities, has lead to the development of numerous computational models (macromolecular, pharmacophore, and structure-activity) for the rationalization and prediction of CYP liabilities. A comprehensive review of these models is presented in this chapter.
