Anthropic 让 Claude 从零设计蝎神经毒素蛋白结合物,211 个候选中 17 个达标

Claude Science tackles deadly scorpion stings by designing protein binders from scratch

文章要点
  • 1Claude 在 Anthropic 的 Claude Science 研究环境中大部分自主地设计了靶向蝎神经毒素的蛋白结合物,初始提示后独立工作 24 小时
  • 2此类蝎毒素每年致死超 3,250 人;Claude 生成 318,484 个设计并选出 180 个候选,加上团队补充的 31 个,211 个进入实验室测试,17 个达标
  • 3最强的两个设计与墨西哥蝎毒素 Cn2 结合极紧密,位点与已知可在小鼠中中和 Cn2 的抗体相同或邻近
  • 4两个独立实验室确认了结果,外部专家称其为有前景的第一步,能否真正用作抗毒血清尚未测试
决策要点

该实验显示大模型已能长时间自主承担分子设计这类科研主环节,但结果仍停留在候选层面,离成药还隔着一整套验证流程。

  • 影响:生物医药研发可把 AI 候选分子生成环节并入早期流程;文中 17/211 的命中率可作为内部评估参照;当前结论止步于体外结合测试,成药风险尚未排除。
  • 参考:可考虑先在蛋白结合物这类体外可验证的筛选场景评估 Claude Science 这类自主科研环境的试点价值;值得把文中 17/211 的命中率设为对照基准。
  • 依据:核心数据为 Anthropic 团队口径,经两个独立实验室确认;抗体位点结论出自实验室测试,抗毒效果未经测试,以上为媒体转述。

Anthropic's Claude largely autonomously designed protein binders targeting scorpion neurotoxins, which kill more than 3,250 people every year. These small protein molecules are shaped to latch onto a specific target molecule. Claude generated 318,484 designs for such protein binders targeting five toxins from four scorpion species. After an initial prompt, Claude worked on its own for 24 hours. The research team then steered the work with additional instructions.

Claude picked 180 candidates, and the team added 31 more. Of the 211 designs tested in the lab, 17 met the criteria for a binder. The two strongest bound extremely tightly to Cn2, a toxin from the Mexican scorpion. Lab tests suggest they dock at or near the same site as an antibody known to neutralize Cn2 in mice. Whether they actually work as an antivenom hasn't been tested yet.

External experts Susana Vázquez Torres and Timothy P. Jenkins called the work a promising first step. Two independent labs confirmed the results. Claude worked inside Claude Science, Anthropic's AI environment for researchers. In an earlier study, Claude had already designed mini-binders against 14 of 15 target proteins, with hit rates of 22 to 35 percent compared to the typical 10 to 15 percent.
