Dihydroberberine	Cardiovascular Disease Alkaloids Structural Classification other families Classification of Application Fields Source classification Plants Isoquinoline Alkaloids Inflammation/Immunology Disease Research Fields	Potassium Channel HSP
Dihydroberberine is a naturally occurring isoquinoline alkaloid with anti-inflammatory, anti-atherosclerotic, hypolipidemic and anti-tumor activities. Dihydroberberine inhibits the human ether-related gene (hERG) channel and significantly reduces the expression of heat shock protein 90 (Hsp90) and its interaction with hERG. Dihydroberberine also blocks the TLR4/MyD88/NF-κB signaling pathway to reduce pro-inflammatory cytokines and immunoglobulins, and has inhibitory effects on DSS (HY-116282C)-induced experimental colitis. Dihydroberberine also increases the sensitivity of lung cancer to sunitinib (HY-10255A), with synergistic efficacy .

Tamoxifen-d3 hydrochloride

Tamoxifen-d₃ hydrochloride is deuterated labeled Tamoxifen (Citrate) (HY-13757). Tamoxifen Citrate (ICI 46474) is an orally active, selective estrogen receptor modulator (SERM) which blocks estrogen action in breast cells and can activate estrogen activity in other cells, such as bone, liver, and uterine cells .Tamoxifen Citrate is a potent Hsp90 activator and enhances the Hsp90 molecular chaperone ATPase activity. Tamoxifen Citrate also potent inhibits infectious EBOV Zaire and Marburg (MARV) with IC₅₀ of 0.1 μM and 1.8 μM, respectively . Tamoxifen Citrate activates autophagy and induces apoptosis .Tamoxifen Citrate also can induce gene knockout of CreER(T2) transgenic mouse .
