剂量决定毒性：生成式药物设计的暴露感知评估
The Dose Makes the Poison: Exposure-Aware Evaluation of Generative Drug Design
AI 导读
研究用PBPK模拟重新评估三个PARP1靶向生成式药物设计流程筛选出的分子，发现60个入围分子中有7个无法达到足够靶点暴露，其余候选中有28%在所需剂量下存在预测安全风险。此外，85%剂量可行的候选分子被静态筛选时忽略的分子所超越，表明纳入剂量与暴露因素会显著改变生成分子的优选结果。

Abstract:Generative models are increasingly used to propose molecules for drug discovery. They can produce far more candidates than can be experimentally tested, making computational selection essential. Most selection methods rely on predicted molecular properties, such as potency and toxicity, but overlook how these properties translate into drug exposure at a given dose. As a result, molecules that appear promising on paper may require impractical doses or raise safety concerns. We investigate this gap by using physiologically based pharmacokinetic (PBPK) simulations to re-evaluate molecules selected from three PARP1-targeted generative pipelines. Of 60 shortlisted molecules, seven fail to achieve sufficient target exposure, while 28% of the remaining candidates show predicted safety risks at their required dose. Moreover, 85% of candidates with an achievable dose are outperformed by molecules overlooked during static selection. These findings suggest that accounting for dose and exposure can substantially change which generated molecules are considered promising for drug development.
