Ansatrienin B is an ansamycin antibiotic and antifungal agent first isolated from S. collinus and S. rishiriensis., In fetal rat long bones, it is an inhibitor of parathyroid hormone-induced calcium release (IC50 = 21 nM), which is a measure of bone resorption, and pp60c-srckinase (IC50 = 50 nM). It is an inhibitor of translation at the protein synthesis stage by specific inhibition of L-leucine incorporation (IC50 = 58 nM in A549 cells). It also inhibits TNF-α-induced expression of intercellular adhesion molecule-1 (ICAM-1; IC50 = 300 nM). Early in vitro studies showed that ansatrienin B potentiates the chemotherapeutic action of 5-fluorouracil , cisplatin , bleomycin , mitomycin C , and 6-mercaptopurine. Ansatrienin B is a hydroquinone form of ansatrienin A .
Tpl2 kinaseinhibitor is an inhibitor of tumor progression locus 2 (Tpl2; IC50= 0.05 μM).1It is selective for Tpl2 over MEK, p38 MAPK, Src, MK2, and PKC (IC50s = >40, 180, >400, 110, and >400 μM, respectively). Tpl2 kinaseinhibitor inhibits LPS-induced TNF-α production in isolated human monocytes and whole blood (IC50s = 0.7 and 8.5 μM, respectively). It enhances differentiation induced by calcitriol in HL-60 and U937 leukemia cells when used at a concentration of 5 μM.2Tpl2 kinaseinhibitor (5 μM) inhibits the proliferation of KG-1a leukemia cells.3 1.Garvin, L.K., Green, N., Hu, Y., et al.Inhibition of Tpl2 kinase and TNF-α production with 1,7-naphthyridine-3-carbonitriles: Synthesis and structure-activity relationshipsBioor.
