Synthesis and antimycobacterial activity of novel heterocycles

摘要

In the present investigation 4-hydroxy-3-methylacetophenone on condensation with various aromatic aldehydes in methanolic KOH solution yielded the corresponding chalcones (C_Ⅰ-C_Ⅺ). These chalcones were further reacted with hydrazi-ne hydrate in ethanol which led to the formation of pyrazoline derivatives (H_Ⅰ-H_Ⅺ). The newly synthesized heterocyles were characterized on the basis of their chemical properties and spcctroscopic data. All newly synthesized compounds were evaluated for their antimycobacterial activities against Mycobacterium tuberculosis H37_(Rv).
