Synthesis and antimycobacterial activity of some heteroarylcarboxamidrazone derivatives.

A series of pyridine-2-, pyrazine-2- and quinoline-2-carboxamidrazone derivatives was prepared in an automated fashion and tested against Mycobacterium fortuitum in a rapid screen. Seven pyridine-2-carboxamidrazone derivatives were investigated further and four were found to have inhibitory activity with compound 4af being the most active. The structure activity implications are discussed.
