Synthesis of 2,4-diamino-5-acetyl(ethoxycarbonyl)pyrimidines from ?-dicarbonyl compounds and dicyandiamide and their use for building a pyrimido[4,5-d]pyrimidine system
摘要:
2,4-Diamino-5-acetyl(ethoxycarbonyl)-6-methyl(phenyl)pyrimidines were obtained by the reaction of acetylacetone and beta-ketocarboxylic acid esters with dicyandiamide in the presence of Ni(OAc)2. It was shown that annelation of the pyrimidine ring with this compound provides a convenient method for building the pyrimido[4,5-d]-pyrimidine system. New derivatives of 2-aminopyrimido[4,5-d]pyrimidine, 7-amino-3H-pyrimido[4,5-d]-pyrimidin-4-one, and 7-amino-1H,3H-pyrimido[4,5-d]-pyrimidine-2,4-dione were synthesized.

the design of inhibitors with both improved potency and selectivity. The approach described herein yielded TRC-19, a promising lead with an IC50 of 9 nM and 89-fold selectivity in favor of Toxoplasma gondii DHFR, as well as crystallographic data to substantiate in silico methodology. Overall, 50% of synthesized in silico designs met hit threshold criteria of IC50 < 10 μM and >2-fold selectivity favoring
