Heterocyclic betaines. 13. Synthesis and electronic and molecular structures of methylenepyridinium and methyleneimidazolium azolate inner salts
摘要:
A convenient synthesis of several examples of betaines 3 and 4 is reported. The electronic and molecular structure of the title betaines 3 and 4 is investigated in terms of a single-crystal diffraction X-ray analysis of compound 7, spectroscopic methods, and experimental dipole moment values (12.34-15.34 D). Semiempirical molecular orbital calculations (MNDO and AM1 methods) provide a useful complementary information to the experimental results.
acknowledged as a risk for atherosclerosis and organophosphate toxicity. The present study describes the synthesis, characterization, PON1 inhibitory properties and molecular docking studies of functionalized imidazolium and benzimidazolium salts (1a–5g). The structures of all compounds were elucidated by IR, NMR, elemental analysis and structures of compounds 2b and 2c were characterized by single-crystal

Water-soluble silver(<scp>i</scp>) complexes with N-donor benzimidazole ligands containing an imidazolium core: stability and preliminary biological studies
with three nitrate anions. A study by the combination of NMR, IR, LC-MS and elemental analysis techniques also suggests that the complexes have this structure both in the solid-state and solution. The complexes are highly soluble and stable in water. Cytotoxicity evaluation against four cancerous human cells and one non-cancerous human cell revealed that the complexes have no significant anti-growth
