Interactions of pyridoxine (Vitamin B6) with squaric acid and water. Experimental and theoretical studies

Synthesis and structural characteristic of pyridine carboxylic acid adducts with squaric acid

“…[11][12][13] Squaric acid (H 2 SQ, 3,4-dihydroxycyclobut-3-ene-1,2-dione) and its salts show promising pharmacological properties. 14 Recently, complexes of squaric acid with isomeric piperidine carboxylic acids, [15][16][17] trigonelline 18 and vitamin B 6 (pyridoxine) 19 have also been studied.…”
