TPSA - Polar Surface Area
Polar surface area (PSA) is a very good descriptors of bioavailabilty. Some time ago we implemented a very efficient method to calculate PSA based on fragment contributions - therefore the abbreviation TPSA what means Topological Polar Surface Area. This method has become industry standard and has been implemented by all major software-houses and many pharmaceutical companies.
Fast Calculation of Molecular Polar Surface Area as a Sum of Fragment-Based Contributions and Its Application to the Prediction of Drug Transport Properties.
