Trachelogenin ((-)-Trachelogenin), isolated from Combretum fruticosum, is an HCV entry inhibitor with anti-proliferative effects. Its mechanism is related to affecting the phosphorylation of key proteins such as β-Catenin, c-Myc and GSK3 in the β-Catenin signaling pathway. chemical and concentration-dependent. Trachelogenin has antiviral, anti-inflammatory and analgesic activities with IC50 of 0.325 and 0.259 μg/mL in HCVcc and HCVpp models, respectively.

3,5-Dimethoxy-2,7-phenanthrenediol (compound 2), extracted from Combretum laxum roots, exhibits cytotoxicity against various human cancer cell lines, including 786-0, MCF-7, and NCI ADR-RES, with IC50 values of 73.26 μM, 118.40 μM, and 83.99 μM, respectively. Additionally, this phenanthrene compound demonstrates free radical scavenging activity, presenting an IC50 of 20.4 μM [1].

2,3,8-tri-O-Methyl ellagic acid has antimicrobial activity agaist Vibro cholera, Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, Bacillus cereus, Escherichia coli.

23-Deoxojessic acid possesses strong cytotoxicity towards highly liver metastatic murine colon 26-L5 carcinoma cells, with ED50 values equal to or less than 6 microM.

Terminolic acid (2α,6β,23-trihydroxyl oleanolic acid) is a pentacyclic triterpenoid glucoside isolated from Combretum racemosum, can inhibit the pro-inflammatory cytokines by binding to receptor active site of IL-1β and IL-6, and enhance anti-inflammatory cytokines by binding to IL-4 receptor binding sites. It also exhibits moderate antibacterial activity.
