Guggulsterone is a plant sterol derived from the gum resin of the tree Commiphora wightii. Guggulsterone inhibits the growth of a wide variety of tumor cells and induces apoptosis through down regulation of antiapoptotic gene products (IAP1, xIAP, Bfl-1/A1, Bcl-2, cFLIP and survivin), modulation of cell cycle proteins (cyclin D1 and c-Myc), activation of caspases and JNK, inhibition of Akt. Guggulsterone, a farnesoid X receptor (FXR) antagonist, decreases CDCA-induced FXR activation with IC50s of 17 and 15 μM for Z- and E-Guggulsterone, respectively.

QBS is a potent cytotoxic compound that induces cell cycle arrest and apoptosis.

Kaurenoic Acid is a natural product isolated and purified from the herbs of Croton antisyphiliticus with anti-inflammatory property, the mechanisms may through inhibition of iNOS and COX-2 expression. Kaurenoic acid is an inducer of apoptosis, which is part of the innate mechanism of cell defense against neoplasia. Kaurenoic acid from A. continentalis may be a useful agent for inhibiting the cariogenic properties of S. mutans.

Polyphyllin VI, a natural product isolated and purified from the rhizomes of Paris yunnanensis Franch. with hemostasis, expectorant, bacteriostasis, anticytotoxic, anti-pregnancy and sperm-killing effects.

Musk ketone, insoluble in water, can increase activity of glutathione S-transferase and thus may prove to be useful cancer chemoprotectant.

LOXO-101 sulfate blocks the ATP binding site of the TRK family of receptors with IC50 of 2 nM to 20 nM against TRKA, TRKB, and TRKC.

Kinetin riboside, a cytokinin analog, can induce apoptosis in cancer cells. It inhibits the proliferation of HCT-15 cells with an IC50 of 2.5 μM.

Rutundic acid, a natural product isolated and purified from the leaves of Ilex pubescens Hook. et Arn. with antitumor activity, exhibits potent tumor cell growth inhibiting property against Hela, A375, HepG2 , NCI-H446, and SPC-A1.

AG 825 is a selective inhibitor of ErbB2 and the IC50 values are 0.15 and 19 μM for ErbB2 and ErbB1 respectively.

Didymin, a natural product isolated and purified from the herbs of Clinopodium chinense with antioxidant property, may be a potential therapeutic molecule for the treatment of neurodegenerative disorders associated with oxidative stress.
