Synthesis, Reactions, and Antiviral Activity of 5′-Acetyl-6′-methyl-2′-thioxo-1′,2′-dihydro-3,4′-bipyridine-3′-carbonitrile
摘要:
Bipyridine-3'0-carbonitrile derivatives 5 reacted with several halogen containing reagents, e. g., 1-chloroacetone, 3-chloropentan-2,4-dione, ethyl chloroacetate, ethyl 2-chloro-3-oxobutanoate, 2-chloroacetamide, chloroacetonitrile, and iodomethane to afford the correspondingthieno [2,3-b]-pyridine derivatives. Considering the data of IR, H-1 NMR, mass spectra and elemental analysis the chemical structures of the newly synthesized heterocyclic compounds elucidated. Cytotoxicity, anti-HSV1, (anti-Herpes Simplex virus type 1) anti-HAV ( Hepatitis A virus), and MBB activity were evaluated for the newly synthesized heterocyclic compounds.

Condensation of pyridinium ylides with pyridylmethylenecyanoacetic ester or pyridylmethylenecyanothioacetamide proceeds stereoselectively to form substituted 4-pyridyl-3-(1-pyridinio)-3,4-trans-1,2,3,4-tetrahydropyridine-6-(olates)thiolates. Substituted 2-(oxo)thio-4-(4-pyridyl)-3-(1-pyridinio)-3,4-trans-1,2,3,4-tetrahydropyridine-6-(olates)thiolates in DMSO-d6 solution exist in tautomeric equilibrium with 4-(4-pyridinio)-3-(1-pyridinio)-1,4-dihydropyridine-2,6-(diolates)-dithiolates.
