We consider the hydrophobicity of the compounds as we design combinatorial libraries or select compounds for purchase. Hence, we need a program that will rapidly calculate the logP of any organic compound. The classic program for this purpose, CLOGP, cannot handle ~30% of the compounds in the Abbott repository. Hence, we started a search for a more general program with acceptable accuracy. This poster describes how well more than a dozen programs predict the logP values for >10,000 compounds in the Pomona and Syracuse lists of reliable values. The open questions are: How fair a comparison is this since many of these very compounds were used to parameterize the various programs? Is there a better or even another way to evaluate the programs? Do you expect that atom- or fragment-based methods can be parameterized for "all" of organic chemistry from the available measurements, or will some 3D method be preferable ultimately?
