Schrodinger Software Release 2022-2

Schrödinger Software Release Overview

Schrödinger continuously strives to develop scientific solutions that push the boundaries of molecular design. We are delighted to share enhanced drug discovery workflows and usability improvements in Schrödinger’s 2022-2 software release, which is now available for download.

What is Schrödinger used for?

Schrödinger develops state-of-the-art chemical simulation software for use in pharmaceutical, biotechnology, and materials research. The physics based computational platform leverages a deep understanding of physics, chemistry, and predictive modeling to accelerate innovation in drug discovery. This allows collaborators to discover high-quality, novel molecules more rapidly, at lower cost, and most likely with a higher likelihood of success compared to traditional methods.
