About 40 percent of all drugs in the Western world are derived from plants. But challenges with producing a reliable supply inherent with materials derived from agricultural processes can lead to drug shortages as climate events, pests, and plant diseases can affect yields. Antheia is harnessing synthetic biology to produce active pharmaceutical ingredients as an alternative to reliance on crop production. We spoke to Christina Smolke, co-founder and CEO of Antheia, about the supply-chain challenges underlying drug shortages, how the company is using synthetic biology to create a reliable supply of active pharmaceutical ingredients, and its growing pipeline of products in development.
