The C-3, C-17 and C-22 congeners of pentacyclic triterpenoids reduced lantadene A (3), B (4) and 22β-hydroxyoleanolic acid (5) were synthesized and were tested in vitro for their NF-κB and IKKβ inhibitory potencies and cytotoxicity against A549 lung cancer cells. The lead congeners 12 and 13 showed
The new series of pentacyclic triterpenoids reduced lantadene A (3), B (4), and 22β-hydroxy-3-oxo-olean-12-en-28-oic acid (5) analogs were synthesized and tested in vitro for their NF-κB and IKKβ inhibitory potencies and cytotoxicity against A549 lung cancer cells. The lead analog (11) showed
The activation of transcription factors nuclear factor-kappa B (NF-κ B) and cyclooxygenase-2 (COX-2) is critical in cancer; they act synergistically in promoting tumor growth, survival, and resistance to chemotherapy. Thus, combined targeting of NF-κ B and COX-2 present an opportunity for
The ring A and D substituted analogs of pentacyclic triterpenoid Lantadene A (1) and B (2) were synthesized and evaluated for in vitro anticancer activity against four human cancer cell lines (HL-60, MCF-7, A549 and HCT-116). Analogs 3, 4, 7 and 8 showed enhanced inhibitory activity as compared with
