From Wet Labs to AI: How Ångström AI is Transforming Pharma

Ångström AI was founded in 2024 in San Francisco by a group of visionary scientists and engineers from the University of Cambridge. The team consists of four active members: Javier Antoran, Jose Miguel Hernandez Lobato, Laurence Midgley, and Gabor. With extensive backgrounds in probabilistic modeling, machine learning research, and molecular simulations, they combined their expertise to create a revolutionary approach to drug development.

The team recognized the need for more efficient and accurate methods in the drug discovery pipeline. Traditional wet lab experiments, while precise, are slow and costly. Machine learning methods, on the other hand, often lack the necessary accuracy due to limitations in training data. Ångström AI aimed to bridge this gap by leveraging generative AI (GenAI) to create molecular simulations that match the precision of wet lab experiments but are significantly faster and more cost-effective.

What Problem Does Ångström AI Address?

During drug discovery and development, pharmaceutical companies need to understand how drug molecules interact with other molecules in the human body. This knowledge is crucial for determining the efficacy and safety of new drug candidates. Conventional methods to assess these molecular interactions have notable drawbacks.

Wet lab experiments are highly accurate but require considerable time and resources. They involve intricate procedures that can take weeks or months to yield results, significantly slowing down the drug development process.

Machine learning prediction methods, such as AlphaFold, offer faster results but often fall short in accuracy. These methods are limited by the quality and quantity of training data, which is itself derived from laborious wet lab experiments. This reliance on data makes them less reliable for precise molecular predictions.

Molecular dynamics simulations, which use the equations of physics to predict molecular interactions, offer a middle ground between wet lab accuracy and machine learning speed. However, the accuracy of these simulations depends on the complexity of the physical models used. More accurate models require more computational power, making them expensive and slow to run.

How Does Ångström AI's Solution Work?

Ångström AI’s innovative solution combines the best aspects of molecular dynamics and generative AI to create fast and accurate molecular simulations. They use a model known as MACE (multi-atomic cluster expansion), which accurately reproduces quantum-mechanical interactions. MACE was developed by Gabor, one of Ångström AI’s co-founders.

MACE simulations have been shown to provide accuracy comparable to lab experiments, particularly in estimating hydration-free energies, a key factor in drug bioavailability. However, these simulations are computationally intensive, each requiring a week of compute time on 8 A100 GPUs.

To overcome this computational barrier, Ångström AI uses diffusion models to accelerate the MACE simulations. These models generate states consistent with physics, but the transitions between states are non-physical and significantly faster. This allows Ångström AI to produce rapid simulations without compromising on accuracy.
