title: A structure-permeability study of small drug-like molecules.
abstract: A systematic structure-permeability relationship study on a set of small drug-like molecules with log D values in the range -2.5 to 3 and carrying a diverse array of functionality reveals that the compounds with log D>0 and <3 are highly permeable. Surprisingly, several tetrazole derivatives were found to be substrates for efflux pump(s).
