Estradiol 17-(β-D-Glucuronide) sodium is a D-ring glucuronide metabolite of natural estrogen formed in the liver. Estradiol 17-(β-D-Glucuronide) sodium is a substrate of the organic anion-transporting polypeptide family (Oatp) and multidrug resistance-associated protein 2 (Mrp2). Estradiol 17-(β-D-Glucuronide) sodium regulates MRP8-mediated transport processes and inhibits MRP8-mediated transport of dehydroepiandrosterone 3-sulfate and taurocholic acid. Estradiol 17-(β-D-Glucuronide) sodium induces immediate, reversible reduction of bile flow and acute intrahepatic cholestasis in female rats without altering the bile acid composition in bile. Estradiol 17-(β-D-Glucuronide) sodium can be used in studies related to intrahepatic cholestasis.

Strophanthidin is a naturally available cardiac glycoside. Strophanthidin 0.1 and 1 nmol/L increases and 1~100 μmol/L inhibits the Na+/K+-ATPase activities, but Strophanthidin 10 and 100 nmol/L does not affect Na+/K+-ATPase activities in cardiac sarcolemmal. Strophanthidin increases both diastolic and systolic intracellular Ca²⁺ concentration.

7β-Hydroxycholesterol is an oxysterol that derived by the oxidation of cholesterol. 7β-hydroxycholesterol can induce cellular oxidative stress, apoptosis, and necrosis, resulting in cytotoxicity. 7β-hydroxycholesterol has antitumor activity.

Sarsasapogenin is a sapogenin from the Chinese medical herb Anemarrhena asphodeloides Bunge, with antidiabetic, anti-oxidative, anticancer and anti-inflamatory activities.

Diosgenin glucoside, a saponin compound extracted from Trillium tschonoskii, provides neuroprotection by regulating microglial M1 polarization. Diosgenin glucoside protects against spinal cord injury by regulating autophagy and alleviating apoptosis .

γ-Oryzanol is a potent DNA methyltransferases (DNMTs) inhibitor in the striatum of mice. γ-Oryzanol significantly inhibits the activities of DNMT1 (IC₅₀=3.2 μM), DNMT3a (IC₅₀=22.3 μM).

Arenobufagin is a natural bufadienolide that can be extracted from toad venom. Arenobufagin can induce apoptosis and autophagy in human hepatocellular carcinoma cells through inhibition of PI3K/Akt/mTOR pathway. Arenobufagin has potent antineoplastic activity against HCC HepG2 cells as well as corresponding multidrug-resistant HepG2/ADM cells. Arenobufagin can inhibit VEGF-mediated angiogenesis through suppression of VEGFR-2 signaling pathway.

Gamabufotalin (Gamabufagin), a main active compound isolated from Chinese medicine Chansu, has been shown to strongly inhibit cancer cell growth and inflammatory response. Gamabufotalin could inhibite angiogenesis by inhibiting the activation of VEGFR-2 signaling pathways.

Bufotalin is a steroid lactone isolated from Venenum Bufonis with potently antitumor activities. Bufotalin induces cancer cell apoptosis and also induces endoplasmic reticulum (ER) stress activation.

Estrone sulfate potassium is an inactive endogenous estrogen that can be converted into Estrone (HY-B0234) and Estradiol (HY-B0141). Estrone sulfate potassium is also a substrate of the OATP1B3 transporter. Estrone sulfate potassium can be converted into Estrone and Estradiol in normal mammary parenchymal cells. Estrone sulfate potassium stimulates the growth of nitrosomethylurea-induced mammary tumors in ovariectomized rats and the colony formation of dispersed nitrosomethylurea mammary cells, with conversion into Estrone and Estradiol occurring both in vivo and in vitro during this process. Estrone sulfate potassium is applicable to breast cancer-related research.

21-Deoxycortisol is an adrenal-specific C21 steroid that accumulates via alternative pathways due to 21-hydroxylase (CYP21A2/P450c21) deficiency. 21-Deoxycortisol serves as a sensitive and specific biomarker for steroid 21-hydroxylase deficiency (21OHD).

Hecogenin is a steroid saponin isolated from Agave sisalana and is a selective inhibitor of human UDP-glucuronosyltransferases. Hecogenin has a wide spectrum of pharmacological activities, including anti-inflammatory, antifungal and gastroprotective effects.

Ophiopogonin D can be isolated from the tubers of Ophiopogon japonicus, is a rare naturally occurring C₂₉ steroidal glycoside. Ophiopogonin D is a CYP2J3 inducer that significantly inhibits Ang II induced NF-κB nuclear translocation, IκBα down-regulation, intracellular Ca²⁺ overload and activation of pro-inflammatory cytokines by increasing the expression of CYP2J2/EETs and PPARα in human umbilical vein endothelial cells (HUVECs). Ophiopogonin D can inhibit isteoclastic differentiation in RAW264.7 cells. Ophiopogonin D has protective effect as an antioxidant in H₂O₂-induced endothelial injury. Ophiopogonin D blocks ERK signaling cascades. Ophiopogonin D alleviates high-fat diet-induced metabolic syndrome and changes the structure of gut microbiota in mice. Ophiopogonin D has been used against inflammatory, metabolic and cardiovascular diseases.
