Original Article


A series of new flavone/isoxazole fused heterocycles 5a–f and flavone/1,2,3-triazole/benzimidazole hybrid heterocycles compounds 7a–t were synthesized via an intramolecular cyclization and Cu(I)-catalyzed click 1,3-dipolar cycloaddition. The products were evaluated for their antiproliferative activity against human breast cancer cell line (MCF-7) using sulforhodamine B assay (SRB) and antimycobacterial activity using turbidometric assay. The majority of the tested compounds exhibited antiproliferative activity and antimycobacterial activity. Compounds 7l, 7q and 7r showed moderate antiproliferative activity with IC50 values 17.9, 14.2, 19.1 \(\upmu \hbox {M}\), respectively, and compound 5a showed moderate antimycobacterial activity with 41.7% of inhibition at 30 \(\upmu \hbox {M}\) concentration.
