Abstract :

Aseries of 5-substituted isoxazoline ring to the tricyclic azepine derivatives were synthesized through 1,3-dipolar cycloaddition reaction. The pure cycloadducts were tested on invasive behavior of murine osteosarcoma cells (LM8G7), which express high amount of chondroitin sulphate and vascular endothelial growth factor. Among tested molecules, 5-[-3-(4-chlorophenyl)-4, 5- dihydroisoxazol-5-yl methyl]-5H dibenzo [b,f] azepine was found to inhibit the invasion of LM8G7 cells strongly than the other structurally related small molecules and inhibited the invasion of human breast cancer cells completely at 10 μM. Furthermore, this compound inhibited the migration of LM8G7 and human ovarian cancer (OVSAHO) cells. Evidently, this compound also inhibited the proliferation of LM8G7, OVSAHO, RPMI 8266 cells-resistant to melphalan cancer cells, and human breast cancer cells (MCF-7) at the tested concentrations. In conclusion, we herein report the in vitro anti-proliferative, anti-migratory, and anti-invasive properties of novel sugar mimetic isoxazolines against malignant cancer cells for the first time.
