Molecular mechanics (MM) is a traditional computational approach when it comes to modeling in synthetic organic chemistry, medicinal chemistry and versatile aspects of drug design. However, MM methods have significant limitations, for example, when used to study electron-based properties within the drug-receptor microenvironment. Quantum mechanical (QM) methods allow to substantially increase the accuracy of predictions and provide much more relevant models of chemical and biological objects and their interactions, but QM methods are extremely (often prohibitively) computationally costly.

However, a series of advancements over recent years allowed to expand horizons in this direction, for example, the emergence of density functional theory (DFT), the overall increase in the computation power and the emergence of distributed cloud-based computational infrastructures.

In this post I am summarizing several notable computational startups, applying quantum calculations methods (always in conjunction with other methods) for drug discovery, and promising to boost the success rates of the pharmaceutical research. Startups are listed in alphabetical order.



ApexQubit is a Berkeley-based startup, founded in 2018 by Denis Farsonov and Nihil Khaine. Combination of reinforcement learning, generative models and quantum computing allows them to search for the most promising undiscovered small molecules and peptides with the final goal to unlock personalized medicine without side-effects.

ApexQubit offers tools for the generation of promising small-size ligands and the estimation of their affinity towards target proteins. Currently, they propose collaboration in order to optimize protein design and are experimenting in gene and cell therapy.

ApexQuibit is funded by Overkill Ventures and HealthInc, a health tech accelerator run by the Amsterdam Health & Technology Institute. In April 2020 ApexQubit received $220K assistance from Nvidia Inception, bringing the total funding to $350K from angels and non-equity sponsors.
