Weak Interactions in Cocrystals of Isoniazid with Glycolic and Mandelic Acids [PDF]

open access: yesCrystals, 2021
This work deals with the preparation of pyridine-3-carbohydrazide (isoniazid, inh) cocrystals with two α-hydroxycarboxylic acids. The interaction of glycolic acid (H2ga) or d,l-mandelic acid (H2ma) resulted in the formation of cocrystals or salts of ...

Microbial transformation of isonicotinic acid hydrazide and isonicotinic acid bySarcina sp

open access: yesJournal of Biosciences, 1979
Metabolism of isonicotinic acid and isoniazid bySarcina sp. led to the formation of two metabolites which were characterised as 2-hydroxyisonicotinic acid and citrazinic acid. The blue pigment formed during fermentation was shown to be derived from the auto-oxidation of citrazinic acid.
