To optimize a drug's capacity to permeate cells, medicinal chemists frequently utilize the polar surface area (PSA) or topological polar surface area (TPSA) of a molecule, which is determined by summing up the surface area of all polar atoms or molecules, including oxygen and nitrogen, as well as any hydrogen atoms connected to them. Molecules with a polar surface area exceeding 140 angstroms squared (Å2) are typically less effective at crossing cell membranes.What is the value of the molecule's polar surface area?
