MolHop框架使AI代理能够发现新颖的分子支架

研究人员开发了MolHop,这是一个新颖的、用于分子发现的代理框架,它超越了简单的优化,能够识别出具有保留功能特性的结构上不同的分子。通过将数百万个分子支架组织成一个分层动作空间,MolHop使AI代理能够导航和编辑化学结构,为复杂的搜索过程保留历史记忆。当与Grok-4.6和DeepSeek-Flash-V4.1等模型集成时,MolHop显著提高了跨支架发现的成功率。此外,通过代理强化学习训练的MolHop-9B模型,通过生成具有更大支架多样性的分子,其性能优于GPT-5.6-sol、Claude-5-Opus和Gemini-3.1-Pro等领先的生成模型。 AI

影响 这项研究展示了一种新的AI驱动的分子发现范式,通过探索多样化的化学空间,有可能加速新药候选物和材料的识别。
