2-Phenyl-pyrido[1,2-a]pyrimidin-4-one derivatives bearing a phenol or a catechol moiety in position 2 were tested as aldose reductase (ALR2) inhibitors and exhibited activity levels in the micromolar/submicromolar range. Introduction of a hydroxy group in position 6 or 9 gave an enhancement of the inhibitory potency (compare 18, 19, 28, and 29 vs 13 and 14). Lengthening of the 2-side chain to benzyl
The present invention provides a control agent that is extremely effective in controlling bacterial diseases. The quorum sensing inhibitor and bacterial disease control agent for agricultural and horticultural use of the present invention contain a pyrimidinone compound represented by General Formula (1) :
wherein R1 represents a C1-5 alkyl group or a phenyl group, and R2 represents a hydrogen atom or a C1-5 alkyl group, provided that R1 cannot be a methyl group when R2 represents a hydrogen atom.
A novel carbonylation of C(sp3)–H bonds in pyridylamines with one atmosphere of CO2 is reported to synthesize important pyrimidinones in good yields. This transition-metal-free and redox-neutral process features the use of a nontoxic carbonyl source, broad substrate scope, good functional group tolerance, facile scalability and easy product derivatization.
