577-PocketXMol:全原子生物分子设计与对接通用模型

from 聊聊Sci

这项研究介绍了一种名为 PocketXMol 的全原子级生成式人工智能模型,旨在统一处理与蛋白质口袋相关的多种分子任务。该模型通过原子级提示(Task Prompt)机制,无需针对特定任务进行微调,即可实现小分子和肽类药物的对接、从头设计及分子优化。实验结果表明,PocketXMol 在 11 项计算基准测试中表现卓越,性能显著超越了包括 AlphaFold 3 在内的 55 个基准模型。在实际应用中,研究人员利用该模型成功设计出了高效的 caspase-9 抑制剂和高亲和力的 PD-L1 结合肽,并通过湿实验验证了其在肿瘤成像和治疗中的潜力。此外,该模型展现了极强的泛化能力,能够处理包含非标准氨基酸的复杂分子设计。总而言之,PocketXMol 为 AI 辅助药物研发提供了一个通用的全原子建模平台,有效衔接了结构预测与分子生成。References: Peng X, Guo R, Guo F, et al.
