Phenanthroindolizidine-based tylophoraalkaloids have been reported to have potential antitumor, anti-immuno and, anti-inflammatory activity. The structure-activity relationships of a series of tylophoraalkaloids were studied to guide future drug design. Our results indicate that although these compounds are structural analogs, their potency of cytotoxicity, selectivity against NF-kappaB signaling
