Oleanolic acid (OA) and its derivatives are a novel emerging class of compounds. Although OA exhibits potent anticancer and anti-inflammatory function, the potential effect of its new derivatives (SZC014) in human breast cancers has not been understood yet. In this investigation, we demonstrated the

Six novel oleanolic acid ring-A fused hybrids (5-10) have been synthesized by employing a four step protocol with the introduction of benzylidene functionality at C-2 as the key step. Their structures were established by high resolution NMR and Mass spectral data. The synthesized compounds have been

Achyranthoside H methyl ester, a novel oleanolic acid saponin derivative from Achyranthes fauriei roots, induces apoptosis in human breast cancer MCF-7 and MDA-MB-453 cells via a caspase activation pathway.
