Multiheteroaryl compounds, their preparation, pharmaceutical compositions comprising these compounds, and their pharmaceutical use in the prevention and treatment of prostaglandin D2 mediated diseases and conditions that may be modulated by the inhibition of hematopoietic prostaglandin D synthase (H-PGDS).

We investigated the structure-activity relationship studies of N-[3, 5-bis(trifluoromethyl)phenyl][2-chloro-4-(trifluoromethyl)pyrimidin-5 -yl]carboxamide (1), an inhibitor of transcription mediated by both NF-kappaB and AP-1 transcription factors, with the goal of improving its potential oral bioavailability. Compounds were examined for cell-based activity, were fit to Lipinski's rule of 5, and were examined for potential gastrointestinal permeability using the intestinal epithelial cell line, Caco-2. Selected groups were substituted at the 2-, 4-, and 5-positions of the pyrimidine ring using solution-phase combinatorial methodology. The introduction of a fluorine in the place of 2-chlorine of 1 resulted in a compound with comparable activity. However, other substitutions at the 2-position resulted in a loss of activity. The trifluoromethyl group at the 4-position could be replaced with a methyl, ethyl, chlorine, or phenyl without a substantial loss of activity. The carboxamide group at the 5-position is critical for activity. If it was moved to the 6-position, the activity was lost. The 2-methyl analogue of 1 (81) showed comparable in vitro activity and improved Caco-2 permeability compared to 1.

The Pinner method was applied to substituted 5-cyanopyrimidines to obtain 5-aminopyrimidines, which were condensed with acrolein derivatives to synthesize compounds that contain a 2,5-bipyrimidine fragment.
