The Role of Artificial Intelligence in Drug Discovery

Article DOI: Biosciences Research & Engineering Network (BREN), 2024,1(1);20-31

Abstract

Artificial Intelligence (AI) has emerged as a transformative tool in the pharmaceutical industry, particularly in drug discovery and development. Traditional drug discovery processes are costly, time-consuming, and prone to high failure rates. AI and machine learning algorithms now provide innovative approaches to identifying drug candidates, predicting molecular interactions, and optimizing clinical trials. This paper reviews recent advancements in AI-driven drug discovery, with case studies highlighting successful applications in oncology, infectious diseases, and rare genetic disorders. The study emphasizes how AI reduces costs, improves efficiency, and accelerates timelines, while also addressing ethical and regulatory challenges.

Introduction:

Drug discovery is a critical yet resource-intensive process in biomedical science. On average, developing a new drug takes 10–15 years and costs billions of dollars, with many potential candidates failing during clinical trials. This inefficiency has long been a barrier to rapid therapeutic development.

The emergence of AI and machine learning (ML) has revolutionized how researchers approach drug discovery. Algorithms can analyze massive datasets, predict protein-ligand interactions, and identify promising compounds in a fraction of the time required by conventional methods. For example, AI-driven platforms have accelerated the discovery of antiviral agents during the COVID-19 pandemic.

Despite the promise, challenges such as data quality, ethical concerns, and regulatory acceptance remain. This paper explores the opportunities and challenges of AI in drug discovery, illustrating its potential to transform pharmaceutical research and development.
