The Traditional Drug Discovery Process: A Historical Overview

Before exploring AI’s impact on drug development, it’s important to understand the traditional process and its challenges. Generally, the process of discovering drugs includes different stages: first, target identification, followed by compound screening, and finally, preclinical and clinical trials.

Target Identification: Researchers identify biological molecules that are usually proteins that are linked to diseases and can be targeted by drugs.
>Hit Discovery: Scientists screen tens of thousands of compounds for potential candidates that could interact with the identified target.
>Lead Optimization: The promising compound is optimized for enhanced efficacy and reduced side effects.
>Preclinical Trials: In vitro and in vivo studies in cell and animal models are carried out to evaluate the safety and efficacy of the drug.
>Clinical Trials: In human trials, the drug is tested for safety, dosage determination, and general efficacy.
>Regulatory Approval: Once a drug has cleared clinical trials, it is then forwarded to regulatory agencies such as the FDA for approval.
The traditional method may be effective, but slow and expensive and more often end in high drug development failure rates. This is where AI comes into play.
