Abstract
Background
Spiropyrrolidine tethered piperidone heterocyclic hybrids were synthesized with complete regio- and stereoselectively in excellent yield via
a
tandem three-component 1,3-dipolar cycloaddition and subsequent enamine reaction in [bmim]Br. The synthesized compounds were evaluated for their anticancer activity against FaDu hypopharyngeal tumor cells.
Findings
Interestingly, most compounds displayed cytotoxicities similar to the standard anticancer agent bleomycin, with two of them (
5a
and
5g
) being slightly more active than the reference drug.
Conclusion
Synthesized compounds have also been evaluated for their apoptosis-inducing properties in a cancer cell model, finding that treatment with compounds
5a
–
e
led to apoptotic cell death.
