Many drugs work by binding to a specific target in the body and blocking or changing what it does…

TL;DR - Anthropic reports that Claude autonomously designed novel protein binders for 14 of 15 targets using an expert-written prompt. Independent synthesis and testing by Adaptyv Bio and Twist Bioscience makes this a notable demonstration of AI-assisted de novo protein design.

• The task was to create proteins from scratch that bind tightly to specified biological targets.
• Claude generated candidate binders autonomously after receiving a protein-design prompt from a human expert.
• The reported designs covered 14 of 15 targets, though the post does not provide quantitative binding or success metrics.
• External partners independently built and tested the designed proteins, moving the work beyond purely computational evaluation.
