How AI helps scientists design the next generation of medicines

AI is transforming how biologic medicines — drugs made from engineered proteins — are designed and developed. Companies like AstraZeneca are using AI to rapidly narrow down millions of possible drug molecules, cutting discovery timelines by up to 50%, according to McKinsey. AstraZeneca is also building a robotic, AI-driven lab in Cambridge, Massachusetts, where automated systems will continuously generate and test thousands of molecules, moving toward fully AI-generated drugs designed from scratch.
