TAK1-IN-2 is a potent and selective TAK1 inhibitor, with an IC50> of 2 nM[1]. TAK1-IN-2 (compound 54) (10 μM) has no effect on cell viability in TNF-α stimulated HCT-15 cells[1]. [1].

RJ-34, an aristolactam analogue, demonstrates strong antitumor effects across a wide range of cancer cell lines, with subnanomolar GI 50 values (GI 50 <0.1 nM) observed for A431, MES-SA, MES-SA DX5, HCT-15, and HCT-15 CLO2 cells [1].
4SC-207 is a novel microtubule inhibitor , which shows strong anti-proliferative activity in a large panel of tumor cell lines with an average GI50 of 11 nM. In particular, 4SC-207 is active in multi-drug resistant cell lines, such as HCT-15 and ACHN, suggesting that it is a poor substrate for drug efflux pumps. 4SC-207 inhibits microtubule growth in vitro and in vivo and promotes, in a dose dependent manner, a mitotic delay arrest, followed by apoptosis or aberrant divisions due to chromosome alignment defects and formation of multi-polar spindles. Furthermore, preliminary data from preclinical studies suggest low propensity towards bone marrow toxicities at concentrations that inhibit tumor growth in paclitaxel-resistant xenograft models. 4SC-207 may be a potential anti-cancer agent.
3-O-(E)-p-coumaroyl tormentic acid may be promising lead compound for developing an effective drug for treatment of leukemia, it induces apoptotic cell death in human leukemia (HL60) via mainly mitochondrial pathway by, at least in part, Topo I inhibition. 3-O-trans-p-coumaroyltormentic acid shows cytotoxicity against four human tumor cell lines (A549, SK-OV-3, SK-MEL-2, and HCT-15) in vitro, the IC50 values of 13.72, 14.29,14.61, 14.04 uM, respectively. 3beta-O-cis-p-Coumaroyltormentic acid, and 3beta-O-trans-p-coumaroyltormentic acid are weakly selective for vancomycin-resistant Enterococcus (VRE) compared with eukaryotic cells, with an MIC of 59.4microg mL and a 50% inhibitory concentration (IC50) of 72.0microg mL for monkey kidney epithelial (MA104) cells. A mixture of 3-O-cis-p-coumaroyltormentic acid and 3-O-trans-p-coumaroyltormentic acid shows an inhibitory effect comparable to (-)-epigallocatechin gallate (EGCG) of green tea on the activation of Epstein-Barr virus early antigen (EBV-EA) induced by 12-O-tetradeca--noylphorbol-13-acetate (TPA).
Coccinic acid shows inhibitory effects against colorectal carcinoma HCT-15 and oral epithelial cell line KB-3-1.Mixture of coccinic acid and anwuweizonic acid shows significant inhibitory activity against human decidual cells and rat luteal cells in vitro
Schizandriside may have anti-inflammatory effects, it has inhibitory activities against nitric oxide and prostaglandin E(2) production in IFN-γ- and lipopolysaccharide-stimulated RAW 264.7 cells. It shows significant cytotoxicity against A549, SK-OV-3, SK
