In the present study, a series of benzofuran-oxadiazole conjugates 7(a-o) was designed, synthesized and characterized through IR, 1H NMR, 13C NMR and mass spectral data. All the compounds were screened for preliminary antitubercular activity against Mycobacterium phlei and Mycobacterium tuberculosis H37RV. Among all the target compounds, the compound possessing chlorine (7k, MIC 1.56 μg/mL) and bromine (7m, MIC 1.56 μg/mL) on 6th position of benzofuran showed highest activity against Mycobacterium phlei. Whereas, bromine on either 5th position (7l, MIC 3.125 μg/mL) or 6th position (7m MIC 3.125 μg/mL) on benzofuran exhibited highest activity for Mycobacterium tuberculosis (H37 RV).

A new series of 4-phenyl-2H-chromene-3-benzimidazoles (8a-o) were synthesized by the condensation of 4-phenyl-2H-chromene-3-carbaldehyde with o-phenylene diamines. The products were purified through column chromatography and structures of these compounds were characterized by IR, 1H & 13C NMR and mass spectral data. All the final compounds were screened for their antimicrobial activity and their efficacy were matched with ciprofloxacin. Five compounds (8b, 8d, 8i, 8l and 8o) were found to be most effective compounds of this series and with activities improved than ciprofloxacin under the tested conditions

Objective: The objective of the study was to synthesis of 1,2,3,4-tetrahydro-4-oxo-6-(5-substituted 2-phenyl-1H-indol-3-yl)-2-thioxopyrimidine-5- carbonitrile derivatives (4a-c). Methods: The structures of all these unknown compounds have been confirmed with the help of physical and spectral techniques such as IR, 1H, and 13C NMR and mass spectral data and these newly synthesized compounds were evaluated for in-vitro antimicrobial and antitubercular activities. Results: Screening studies have demonstrated that the newly synthesized compound 4a exhibited promising antimicrobial and antitubercular properties. Conclusion: The final results revealed that compound 4a exhibited promising antimicrobial and antitubercular properties when compared to the standard drugs.
