Synthesis, Antitubercular and Antibacterial Activities of Some Quinazolinone Analogs Substituted with Benzothiophene

A novel series of 3-chloro-N-(4-oxo-2-arylquinazolin-3(4H)-yl)-1-benzothiophene-2-ca r boxamide analogs derived from 3-amino-2-arylquinazolin-4(3H)-one have been synthesized in good yields and characterized by IR, super( 1)HNMR, mass spectral and elemental analyses. All the compounds were evaluated...

description A novel series of 3-chloro-N-(4-oxo-2-arylquinazolin-3(4H)-yl)-1-benzothiophene-2-ca r boxamide analogs derived from 3-amino-2-arylquinazolin-4(3H)-one have been synthesized in good yields and characterized by IR, super( 1)HNMR, mass spectral and elemental analyses. All the compounds were evaluated for their in vitro antibacterial activity against Gram-positive and Gram-negative bacteria and were also screened for antitubercular activity against Mycobacterium tuberculosis H sub( 37)Rv strain by microplate alamar blue method. The compounds 3b and 3h showed good antitubercular and the compound 3a exhibited good antibacterial activity.
