摘要
背景:新药的发现和开发是一项漫长而昂贵的旅程,从开始构思到批准和营销新药大约需要20年。尽管过去几年中研发支出一直在不断增加,但是引入市场的新药数量一直在稳步下降。这主要是由于临床前和临床安全性问题,仍然占停药的40%。为了解决这个问题,目前许多计算机技术用于潜在安全问题的早期评估/预测,从而可以提高药物发现的成功率并降低与新药开发相关的成本。 方法:在本综述中,我们将分析药物发现流程的早期步骤,描述从疾病选择到潜在客户优化的步骤顺序,并重点介绍用于评估减员风险和制定缓解计划的最常用的计算机工具。 结果:提供了可以在药物发现管道中有效实施和使用的广泛使用的计算机软件工具,数据库和公共计划的完整列表。还提供了一些有关这些工具如何解决问题以及如何增加药物发现和开发计划成功率的示例。最后,将给出一些示例,这些示例中计算机软件的应用已有效促进了上市药物或临床候选药物的开发。 结论:in silico工具箱在早期药物发现的每个步骤中都有很好的应用:(i)目标识别和验证; (ii)命中识别; (iii)领先(iv)优化销售线索。已详细描述了这些步骤中的每一个步骤,从而有效地概述了计算机软件工具在加快新药发现过程的决策过程中所起的作用。
关键词: 药物发现,计算化学,目标验证,先导物,先导化合物的优化,人类基因组测序。
