CAPE is the phenethyl alcohol ester of caffeic acid and a bioactive component of honeybee hive propolis. In addition, CAPE inhibits PDGF-induced proliferation of vascular smooth muscle cells through the activation of p38 mitogen-activated protein kinase (MAPK) and hypoxia-inducible factor (HIF)-1alpha and subsequent induction of heme oxygenase-1 (HO-1).

Pyridoxine hydrochloride (Vitamin B6) is the 4-methanol form of vitaminB6 which is converted to pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid.

Ethyl ferulate could be used for therapeutic purposes as a potent inducer of HO-1 for the protection of brain cells against oxidative and neurodegenerative conditions.

Cerevisterol is a cytotoxic steroid, can inhibit the activity of DNA polymerase alpha. It can stimulate NGF-mediated neurite outgrowth on PC12 cells.

Ganodermanontriol, a sterol derived from Ganoderma lucidum, showcases hepatoprotective activity and possesses anti-inflammatory properties in tert-butyl hydroperoxide (t-BHP)-damaged hepatic cells through the upregulation of HO-1 expression.

Danshensu has antioxidant activity, can enhance HO-1 expression to suppress 6-OHDA-induced oxidative damage via PI3K Akt Nrf2 signaling pathways.

Latifolin is a strong DPPH-scavenger, it attenuates inflammatory responses by inhibiting NF-κB activation via Nrf2-mediated heme oxygenase-1 expression. Latifolin displays potent anticarcinogenic phase II marker enzyme, quinone reductase (QR) inducing activity and high chemopreventive indices. Latifolin also shows antifungal activity against white- and brown-rot fungi.

Momordin Ic (Momordin 1c) might represent a potential anticancer activity, by inducing apoptosis through oxidative stress-regulated mitochondrial dysfunction involving the MAPK and PI3K-mediated iNOS and HO-1 pathways. Also, Momordin Ic accelerates gastrointestinal transit partially by stimulating synthesis of 5-HT to act through 5-HT(2), which, in turn, increases synthesis of prostaglandins.

Mollugin (Rubimaillin) may be a JAK2 inhibitor and inhibits LPS-induced inflammatory responses by blocking the activation of the JAK-STAT pathway. Mollugin as a candidate for a chemotherapeutic agent in OSCCs via the upregulation of the HO-1 and Nrf2 pathways and the downregulation of NF- κ B. Mollugin may be a novel therapeutic candidate for bone loss-associated disorders including osteoporosis, rheumatoid arthritis, and periodontitis. Also, it has anticancer efficacy, can modulate the HER2 pathway in HER2-overexpressing Y cells with a potential role in the treatment and prevention of human breast and ovarian Y with HER2 overexpression.
