克劳德·桑西通过从零开始设计蛋白质结合剂,来应对致命的蝎子蜇伤问题。

原文标题 · Claude Science tackles deadly scorpion stings by designing protein binders from scratch

Anthropic公司的Claude独立设计了能够结合致命蝎子神经毒素的蛋白质载体。在超过318,000种设计方案中,有211种在实验室中进行了测试。其中17种方案符合标准,而最有效的两种方案能够非常牢固地结合墨西哥蝎子所分泌的Cn2毒素。不过,这些设计是否真的能作为抗蛇毒血清仍然是一个未知数。这篇文章《Claude通过从零开始设计蛋白质载体来应对致命蝎子蜇伤》首次发表在The Decoder上。

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

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. Ad Ad
