As an analogy, the phrase most cars sold are red or black is a very different statement to factories should make red or black cars only. ISSN 2529-8992 The earliest thorough analysis of ADME properties was performed by Lipinski and resulted in the famous "rule of 5", which argues that poor absorption is more likely if: The number of hydrogen bond donors (HBDs) >5 (counting the sum of all NH and OH groups) The number of hydrogen bond acceptors (HBAs) >10 (counting all N and O atoms) Why?
