Claude设计蛋白结合体对抗蝎毒
Claude Science tackles deadly scorpion stings by designing protein binders from scratch
Anthropic的AI系统Claude自主设计了318,484种针对四种蝎子五种毒素的蛋白结合体,经测试有17种符合标准,其中两种对墨西哥蝎子毒素Cn2结合力极强,专家称其为有前景的初步进展,但尚未在体内验证其作为抗蛇毒的效果。
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.
