Synthesis and In Silico Screening of Biological Activity of Novel Bisazomethines Containing 1,3-Diazine Fragment: Perspectives in Organic Synthesis and Pharmaceuticals

Chemistry Proceedings
Bridged 1,3-diazine bisazomethines were synthesized via the nucleophilic addition of phenylenediamines to 4,6-dihydroxypyrimidine-5-carbaldehydes in methanol/water. Structures were confirmed by NMR spectroscopy. In silico screening (PASS-online, CLC-pred,
