    Garcinone C
    		Activator 99.51%
    Garcinone C, a xanthone derivative, is a natural compound extracted from Garcinia oblongifolia that is used as an anti-inflammatory, astringency and granulation-promoting medicine, and has potential cytotoxic effects on certain cancers. Garcinone C stimulates the expression levels of ATR and 4E-BP1, arrests the cell cycle, inhibits cell viability of the human Nasopharyngeal carcinoma (NPC) cell lines CNE1, CNE2, HK1 and HONE1 in a time‑ and dose‑dependent manner through inhibition of Hedgehog signaling pathway. Garcinone C is orally active.

    Americanin A
    		Activator
    Americanin A is a Neolignan. Americanin A can be isolated from the seeds of Phytolacca americana. Americanin A activates ATM and ATR, initiating the subsequent signal transduction cascades that include Chk1, Chk2, and tumor suppressor p53. Americanin A targets selectively Skp2 for degradation and thereby stabilizes p27. Americanin A suppresses the activity of Cyclin B1 and its partner cdc2 to prevent entry into Mitosis. Americanin A induces Apoptosis by producing excessive ROS. Americanin A has anti-cancer activity against colorectal cancer.
