Descriptions:
Xanthatin, a natural sesquiterpene lactone, has significant antitumor activity against a variety of cancer cells; it displays significant antitumor effects through cell cycle arrest and apoptosis induction in A549 cells, these effects are associated with intrinsic apoptosis pathway and disrupted NF-κB signaling, suggests that it may have therapeutic potential against human non-small-cell lung cancer.[1]
Xanthatin has bactericidal and fungicidal activity, including against Colletotrichum gloesporoides, Trichothecium roseum, Bacillus cereus and Staphylococcus aureus.[2]
Xanthatin and the crude extracts of Xanthium strumarium have cytotoxic activity.[3]
(?)-Xanthatin is a highly effective inhibitor of MDA-MB-231 cell growth, inducing caspase-independent cell death, and that these effects were independent of FTase inhibition; GADD45γ was selectively induced by (?)-xanthatin and that GADD45γ-primed JNK and p38 signaling pathways are, at least in part, involved in mediating the growth inhibition and potential anticancer activities of this agent; GADD45γ is becoming increasingly recognized for its tumor suppressor function, suggests that the novel possibility that (?)-xanthatin may have therapeutic value as a selective inducer of GADD45γ in human cancer cells, in particular in FTI-resistant aggressive breast cancers.[4]
Xanthatin induces G2/M cell cycle arrest and apoptosis in human gastric carcinoma MKN-45 cells, it may have therapeutic potential against human gastric carcinoma.[5]
Xanthatin is a novel potent inhibitor of VEGFR2 signaling, can inhibit angiogenesis and tumor growth in breast cancer cells.[6]
