cf. C.A. 46, 9714c. Acetylpyrazine, cyanopyrazine, pyrazine thiocarboxamide, and mercaptopyrazine were reversible nicotinamide antagonists for Lactobacillus arabinosus, while 37 related compounds were inactive. No significant inhibition of the nicotinamide growth response could be demonstrated in rats or chicks.
