Artificial intelligence has profoundly impacted the efficiency and scope of lead discovery and optimization processes within the pharmaceutical industry. AI-powered virtual screening techniques enable researchers to rapidly and cost-effectively examine vast libraries of chemical compounds, significantly increasing the probability of identifying promising lead candidates for further development.1 This approach utilizes AI algorithms to predict the potential efficacy of novel drugs by meticulously analyzing their chemical structures and forecasting their interactions with specific target proteins.13 The speed and scale offered by AI-driven virtual screening allow for the exploration of chemical spaces far exceeding the capacity of traditional methods, often processing millions of compounds in a fraction of the time.14 This capability represents a substantial acceleration in the initial stages of identifying molecules with therapeutic potential.
The advent of generative AI has ushered in a new era in the de novo design of novel drug molecules. Unlike traditional methods that rely on screening existing compound libraries, generative AI systems possess the capability to create entirely new molecules from scratch, tailored to exhibit specific desired properties.15 Sophisticated generative AI models, such as Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs), play a crucial role in optimizing these drug candidates by accurately predicting how subtle structural modifications will impact their biological activity and overall safety profiles.16 Furthermore, AI algorithms can intelligently generate novel molecules with predefined characteristics expected to enhance their therapeutic potential, offering a powerful tool for expanding the chemical space explored in drug discovery.7 This ability to design novel compounds with specific attributes opens up exciting possibilities for developing breakthrough therapies that may not be discoverable through conventional screening approaches.
Machine learning models are also indispensable in predicting critical ADMET (absorption, distribution, metabolism, excretion, toxicity) properties of potential drug candidates and in guiding the optimization of identified lead compounds. AI can significantly reduce the number of compounds requiring experimental testing and streamline the process of refining initial drug candidates.1 Machine learning algorithms can accurately predict the solubility and stability of compounds, facilitating the development of more efficient and effective drug formulations.11 Moreover, AI models excel at predicting the safety profiles of drug candidates by analyzing extensive preclinical data, thereby minimizing the risk of encountering adverse events during subsequent clinical trials.3 Advanced AI algorithms can also predict crucial ADMET properties, leading to reduced development costs and improved interactions between the drug and its intended target.17 This early prediction of key pharmacological properties through AI enables researchers to select safer and more efficacious lead compounds, significantly reducing the likelihood of failure in the later, more expensive stages of drug development.
