A novel hydrogen bond-forming ligand for pyrimidine/purine transversion, which contains both a fluorescent naphthyridine moiety and a ferrocenyl group as an electrochemical indicator, is described. Hydrogen bond-mediated recognition for a target nucleobase at an abasic site in a DNA duplex is confirmed by both fluorescence and electrochemical measurements. The analysis by fluorescence titration...

This study describes the organic synthesis of 5-(2-amimo-4-styryl pyrimidine-4-yl)-4-methoxy benzofuran-6-ol (SPBF) as an example of a benzofuran derivative used as a new series of amyloid imaging agents. These benzofuran derivatives may be useful amyloid imaging agents for detecting B-amyloid plagues in the brain of Alzheimer’s disease. The precursor is 1-[6-hydroxy-4-methoxybenzofuran-5-yl]-p...

Aims: To evaluate the antiplasmodial activity of a trisdimethylamino pyrimidine derivative synthesized by indirect methylation p-nitrophenylacetic acid via substituted amine or amide against Plasmodium berghei NK65 strain in an vivo berghei-Infected mouse model.
 Methodology: berghei-parasitized suppressive model Albino mice was adopted for evaluation. The schizontocidal compound evaluated...

A biologically active antibacterial reagent, 2-amino-6-hydroxy-4-(4-N, N-dimethylaminophenyl)-pyrimidine-5-carbonitrile (AHDMAPPC), was synthesized. It was employed to investigate the binding interaction with the bovine serum albumin (BSA) in detail using different spectroscopic methods. It exhibited antibacterial activity against Escherichia coli and Staphylococcus aureus which are common food...

A novel series of 3-(2-amino-6-pyrimidin-4-yl)-6-bromo-2H-chromen-2-one (5a-5j) were synthesized from 3-acetyl-6-bromo-2H-chromen-2-one (3). The structures of the synthesized compounds were elucidated by IR, H-NMR, C-NMR, and mass spectroscopic techniques. The synthesized compounds were screened for in-vivo analgesic activity at a dose of 20 mg/kg body weight. Among them, compounds 5a, 5b and 5...

An electroorganic reaction for the synthesis of 7-amino-2, 4-dioxo-5-phenyl-2,3,4,5-tetrahydro-1H-pyrano[2, 3-d] pyrimidine-6-carbonitrile and ethyl-7-amino-2, 4-dioxo-5-phenyl-2,3,4,5-tetrahydro-1H-pyrano[2, 3-d] pyrimidine-6-carboxylate derivatives are described, using an electrogenerated base of the anion of malonitrile or ethylcyanoacetate. This one-pot, three-component condensation of an a...

In an endeavor to find a novel series of antihyperglycemic agents, new benzimidazole and pyrimidine derivatives were successfully synthesized efficiently in high yield with high purity, starting from amino acids in the presence of phosphorus oxychloride (POCl3). The synthesized compounds were identified by 1H-NMR, 13C-NMR, FT-IR spectroscopic techniques and elemental analysis. All products were...
