AI in biotechnology and Drug Development

Discovering new drugs has always been a tough and costly process, taking up a lot of time and money. The need for reform in this crucial field has been emphasized due to these challenges. Despite previous attempts to speed up drug discovery using computational methods, progress has been slow.

Now, artificial intelligence in drug discovery and development has emerged as an exciting solution with great potential to revolutionize the Industry. AI helps identify the best drug candidates, offers unprecedented insights into various diseases, and efficiently manages extensive patient datasets. These capabilities are bringing transformative change to the pharmaceutical landscape.

According to McKinsey, incorporating AI into big data strategies in the US healthcare system could potentially generate an annual value of up to $100 billion. This involves using predictive modeling and analyzing sensor data comprehensively.

Furthermore, a joint research effort by Carnegie Mellon University and a well-known German institution has highlighted that AI in drug discovery significantly cuts down on expenses, potentially allowing  AI drug discovery companies to reduce costs by up to 70%. In this article, we’ll explore the impact of artificial intelligence on drug discovery and development and how these advanced techniques are revolutionizing healthcare.

The Role of Artificial Intelligence in Drug Discovery

Drug discovery research aims to find effective medications for specific diseases by positively influencing the body. Traditionally, researchers extensively screen molecular libraries to pinpoint a molecule that binds to a target molecule, typically a protein linked to a specific disease. Subsequently, these identified molecules undergo multiple rounds of testing to refine them into potential drug candidates.

Recent trends show an increasing acceptance of rational, structure-based drug design methods. While these approaches skip initial screening stages, they still require chemists to design, synthesize, and evaluate numerous compounds 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. Consequently, refining a promising compound into a viable drug candidate becomes a resource-intensive and time-consuming process. Current data suggests that bringing a new drug to market costs around $2.6 billion.

Furthermore, even if a new drug shows promise during laboratory testing, it may encounter obstacles during the clinical trial phase. Phase I trials for these drug candidates reveal that only 9.6% of them successfully reach 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 expedite the process and reduce costs, acting as a catalyst. Bekryl, a market research firm, forecasts that the incorporation of AI into the drug discovery process could result in savings surpassing $70 billion by 2028.
