Amarogentin is an agonist for the bitter taste receptor TAS2R1 and inhibits in LAD-2 cells substance P-induced production of newly synthesized TNF-α. Amarogentin induces apoptosis in human gastric cancer cells (SNU-16) through G2/M cell cycle arrest and PI3K/Akt signalling pathway. Amarogentin (AG) interacts with the α2 subunit of AMP-activated protein kinase (AMPK) and activates the trimeric kinase with EC50 of 277 pM. |

ResibufogeninResibufogenin (Bufogenin, Recibufogenin), a component of huachansu with anticancer effect, triggers necroptosis through upregulating receptor-interacting protein kinase 3 (RIP3) and phosphorylating mixed lineage kinase domain-like protein at Ser358. Resibufogenin exerts cytotoxic effect by inducing reactive oxygen species (ROS) accumulation. Resibufogenin induces apoptosis and caspase-3 and caspase-8 activity. Resibufogenin increases Bax/Bcl-2 expression, and suppresses cyclin D1, cyclin E, PI3K, p-AKT, p-GSK3β and β-catenin protein expression. |

AmarogentinAmarogentin (AG), a secoiridoid glycoside mainly extracted from Swertia and Gentiana roots, exhibits anti-oxidative, anti-tumour, and anti-diabetic activities. Amarogentin is an agonist for the bitter taste receptor TAS2R1 and inhibits in LAD-2 cells substance P-induced production of newly synthesized TNF-α. Amarogentin induces apoptosis in human gastric cancer cells (SNU-16) through G2/M cell cycle arrest and PI3K/Akt signalling pathway. Amarogentin (AG) interacts with the α2 subunit of AMP-activated protein kinase (AMPK) and activates the trimeric kinase with EC50 of 277 pM. |

Demethyl-CoclaurineDemethyl-Coclaurine (Higenamine, Norcoclaurine), the key component of the Chinese herb aconite root, is a beta-2 adrenergic receptor (β2-AR) agonist. Demethyl-Coclaurine stimulates AKT phosphorylation and requires PI3K activation for the anti-apoptotic effect in cardiomyocytes. |

HomosalateHomosalate (HMS, Homomenthyl salicylate) is an organic ultraviolet filter used in most sunscreens but has been reported to be toxic to marine organisms. Homosalate aggravates the invasion of human trophoblast cells as well as regulates intracellular signaling pathways including PI3K/AKT and MAPK pathways. |
