Pentacosanoic Acid is a long-chain saturated monobasic fatty acid with an odd number of carbon atoms in the chain. Pentacosanoic acid, like most long-chain fatty acids with an odd number of carbon atoms, was found in nature at low concentrations.

5-O-Caffeoylshikimic acid is a characteristic phenolic compound mainly found in the Palmae family. 5-O-Caffeoylshikimic acid was isolated from such plants as Vaccinium corymbosum, Livistona chinensis to name a few. The drug demonstrated the antiproliferative activity against different cancer cell lines. 5-O-Caffeoylshikimic acid could promote cancer cell apoptosis and block cancer cell adhesion, invasion and migration by inhibiting transforming growth factor beta 1 (TGF-beta1) signaling pathway.
