So, in this article, we will discuss the power of artificial intelligence in drug discovery and development and how these advanced AI techniques revolutionize healthcare.
Role of Artificial Intelligence in Drug Discovery and Development
Drug discovery research focuses on finding medications that effectively treat specific diseases by positively affecting the body. Researchers traditionally conduct thorough screenings of molecular libraries to identify a molecule that can bind to a target molecule, particularly a protein associated with a specific disease. Following this, these identified molecules undergo multiple rounds of testing to refine them into potential drug candidates.
Recent trends indicate a rising acceptance of rational, structure-based drug design methods. These approaches, while bypassing initial screening stages, still require chemists to undertake the design, synthesis, and evaluation of numerous compounds in order to identify potential new drugs.
The challenge lies in the uncertainty surrounding which chemical structures possess the desired biological effects and necessary properties for effective drug function. As a result, refining a promising compound into a viable drug candidate becomes a resource-intensive and time-consuming process. Current data indicates that bringing a new drug to market now costs around $2.6 billion.
Moreover, even if a new drug shows promise during laboratory testing, it may encounter obstacles throughout the clinical trial phase. Phase I trials for these drug candidates demonstrate that 9.6% of them are successful in reaching the market.
The data processing capabilities of AI systems have gained significant attention due to the challenges faced. Experts predict that AI for drug discovery can accelerate the process and reduce costs, serving as a catalyst. Market research firm Bekryl has projected potential savings, exceeding $70 billion in the drug discovery process by 2028 through the integration of AI.
