According to Precedence Research, the global market for generative AI in drug discovery is projected to reach around USD 1,417.83 million by 2032, increasing from USD 142.09 million in 2023 (a CAGR of 27.38 percent).

    How Does Generative AI Work in Drug Discovery?

    Generative AI is an important part of drug discovery because it uses machine learning algorithms to make and improve possible drug candidates. A huge amount of existing data, such as chemical structures and biological activity, is used to teach the model what to do. This model uses the patterns and examples in the data to make new molecules with the desired properties.

    Generative AI works well because it can quickly search huge chemical spaces for possible new drugs. With the help of AI, researchers can better navigate the tricky world of drug development. This brings researchers closer to finding disease treatments that will change the game.

    What Is The Role Of Generative AI In Drug Discovery Process?

    Generative AI’s goal in drug discovery is to change and speed up the process of finding possible therapeutic molecules. Machine learning algorithms such as generative adversarial networks (GANs), graph neural networks (GNNs), and recurrent neural networks (RNNs) can be used by generative artificial intelligence (AI) to improve drug designs, make new molecular structures, and help with de novo drug design. By utilizing this capability, researchers can scour a vast chemical space for potential drug candidates which may have gone unnoticed using more conventional methods.

    Generative AI greatly impacts the drug discovery process, making it faster and better at every step, from basic research to post-market surveillance. Let us have a look at the role of Generative AI in each stage of the drug discovery process.
