Generative AI in Pharmaceuticals (Revolutionizing Drug Discovery)
Updated · May 23, 2023
Introduction to Generative AIArtificial Intelligence (AI) is a fast-evolving technology that has been changing various industries in recent years. Whether it’s healthcare, manufacturing, or other sectors, AI is changing the way we work. One industry that’s adopted AI early on is the pharmaceutical industry, particularly in the discovery and creation of new drugs. This article will highlight a specific AI aspect, Generative AI, and its role in the pharmaceutical sector.
What’s Generative AI?Generative AI is a type of AI that uses mathematical rules to create new information that’s similar to the original data it was taught with. The original data can be anything – pictures, written words, or even the structure of chemicals. As a part of machine learning, Generative AI uses what we call neural networks to understand patterns in the original data and create new data that resembles it. This technology has great potential in the pharmaceutical industry, especially when it comes to discovering and developing new drugs. By creating new molecules with specific features, Generative AI can speed up the drug discovery process, helping pharmaceutical companies create new medicines faster and more effectively. Generative AI operates using a machine learning method that involves two neural networks – one that generates and another that discriminates. The generator network creates new data that imitates real-world information, while the discriminator network tries to tell the difference between the created data and the real-world data. With time, the generator network gets better at making data that’s nearly indistinguishable from real-world information. Generative AI falls under a category of machine learning known as unsupervised learning, which means it can learn from data that hasn’t been labelled. This is a big plus, as it allows the technology to create new data without the need for existing datasets.
Which kinds of Generative AI tools are utilized in the Pharmaceutical Industry?There are several types of Generative AI tools that the pharmacy field uses to tackle different issues and tasks. Here are some of the commonly used Generative AI tools in the pharmacy sector:
- Generative Adversarial Networks (GANs): These tools are popular in pharmacy research for creating new drugs and generating molecules. GANs have a generator network that makes synthetic samples and a discriminator network that checks if these samples are authentic. This process leads to the creation of new molecules with the desired features.
- Recurrent Neural Networks (RNNs): RNNs are used for creating sequential data, which is useful in forming new chemical structures or improving the properties of drugs. RNNs learn the patterns in sequential data, which allows them to make new sequences that have the desired characteristics.
- Variational Autoencoders (VAEs): These tools are used in discovering and improving drugs. VAEs understand the distribution of chemical structures and can create new molecules with specific features. They are very useful in examining the chemical space and creating diverse compounds.
- Deep Reinforcement Learning: This type of learning is used in discovering and improving drugs. These algorithms learn by trying and making errors, and they can create molecules with the desired features by maximizing rewards based on pre-set objectives.
- Transformer Models: Transformer models, like the popular GPT (Generative Pre-trained Transformer) model, are used in tasks that involve processing natural language, like creating text and discovering drugs. These models can create text that makes sense and is relevant to the context, which makes them useful for creating descriptions of chemicals and text related to drugs.
What are the uses of Generative AI in the Pharmaceutical field?Here are some ways that Generative AI is used in the pharmaceutical industry:
Creating New Drugs/Drug Discovery
Improving Drug Candidates/Lead Optimization
Finding New Uses for Drugs/Drug Repurposing
Creating Personalized Medicines
How Generative AI Can Change the Pharmaceutical Industry?The pharmaceutical industry, which is subject to many rules and regulations, takes a long time and costs a lot to create new drugs. This process involves a lot of testing and approval from authorities like the FDA (Food and Drug Administration). However, generative AI can bring a big change to this process by making it faster and less costly to get a new drug to the market.

By conducting scientific research, I write about illness, health and healthcare. As a professional medical writer, my experience includes creating feature articles for newsletters and websites as well as research news stories for doctors and researchers. Reading has been an integral part of me since childhood - I'm fan of "Friends" and the "Harry Potter series". Before this career, I was employed by a French multinational company. However, my passion for reading led me to pursue writing professionally; my first Amazon-published short story entitled "The envelope that changed our lives" has recently been released. In my free moments, I enjoy long bike rides around town.
