The definition of the polar surface area (PSA) or topological polar surface area (TPSA) of a molecule is the summation of surface area over all polar atoms or molecules, which mainly consists of oxygen and nitrogen, along with their corresponding hydrogen atoms. In the field of medicinal chemistry, PSA is a widely used metric to refine the capacity of a drug to permeate cells, which further assists in optimizing its clinical efficacy. It is to be noted that molecules with a polar surface area exceeding 140 angstroms squared (Å2) demonstrate a tendency of being deficient in penetrating the cell membranes.Could you please provide me with the specific value of the molecular polar surface area?
