Synthesis and biological evaluation of novel flavone/triazole/benzimidazole hybrids and flavone/isoxazole-annulated heterocycles as antiproliferative and antimycobacterial agents

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...
