Metal chelates and antitubercular activity V : Riboflavin, riboflavin-5′-phosphate, alloxan, phthaloylhydrazine

Abstract

Metal complexes, which are probably chelates, have been prepared of riboflavin, roboflavin-5′-phosphate, alloxan, and phthaloylhydrazine using divalent copper, cobalt, nickel, iron, and zinc ions. Antitubercular tests in mice showed these chelates to be essentially inactive.
