Oroxin B (OB) is a BBB-permeable flavonoid isolated from traditional Chinese herbal medicine Oroxylum indicum (L.) Vent. Oroxin B (OB) possesses obvious inhibitory effect and induces early apoptosis rather than late apoptosis on liver cancer cells through upregulation of PTEN, down regulation of COX-2, VEGF, PI3K, and p-AKT. Oroxin B (OB) selectively induces tumor-suppressive ER stress in malignant lymphoma cells.

Lapachol, a natural naphthoquinone, is an orally active, potent DHODH inhibitor. Lapachol has immunosuppressive activity on lymphocytes through its direct ability to block DHODH activity and inhibit pyrimidine synthesis. Lapachol is a vitamin K antagonist with antitumor activity and can inhibit DNA and RNA synthesis in neoplastic cells. Lapachol has anti-Leishmania activity.

Oroxin A is the major component of an ethanol-water Oroxylum indicum (L.) Kurz (Bignoniaceae) seed extract (OISE). Oroxin A acts as a partial PPARγ agonist that can activate PPARγ transcriptional activation. Oroxin A activates PPARγ by docking into the PPARγ protein ligand-binding domain. Oroxin A also exhibits an inhibitory activity against α-glucosidase and an antioxidant capacity. Oroxin A exerts anti-breast cancer effects by inducing ER stress-mediated senescence.

Sterekunthal B is a naphthoquinone compound and antimalarial agent. Sterekunthal B can be isolated from plants of the Bignoniaceae family, including the root bark of Stereospermum colais. Sterekunthal B inhibits the growth of Chloroquine (HY-17589A)-sensitive Plasmodium falciparum strain PoW with an IC₅₀ of 23.3 μg/mL. Sterekunthal B also inhibits the growth of Chloroquine-resistant Plasmodium falciparum strain Dd2 with an IC₅₀ of 15.2 μg/mL. Sterekunthal B exhibits non-selective cytotoxicity toward endothelial cells. Sterekunthal B can be used in malaria-related research.

Vitamin K2 (5) (Compound 1) is a prenylogue of the Vitamin K2 (HY-109569) series that can be found in the heartwood of Tabebuia avellanedae.

(-)-Cycloolivil 6-O-β-D-glucopyranoside is a lignan glycoside that can be isolated from the leaves and branches of Stereospermum cylindricum.

5,6,7-Trimethoxyflavone is a flavonoid compound that can be isolated from plants Callicarpa japonica. 5,6,7-Trimethoxyflavone exhibits antiviral and anti-inflammatory activities through inhibition of NF-κB/AP-1/STAT signaling pathway.

Chrysin-7-O-glucuronide is a flavonoid found in Scutellaria baicalensis. Chrysin-7-O-glucuronide inhibits α-glucosidase and α-amylase with IC₅₀ values of 612.13 and 980.73 μg/mL. Chrysin-7-O-glucuronide suppresses NF-κB signaling activity. Chrysin-7-O-glucuronide scavenges free radicals, acts as a tight junction protector, and mitigates intestinal mucosal barrier injury. Chrysin-7-O-glucuronide can be used for the research of type 2 diabetes and severe acute pancreatitis-induced intestinal mucosal barrier injury.

Citreorosein is a natural product that can be isolated from Xanthoria parietina.

Minecoside is a CXCR4/STAT3 inhibitor with anticancer and anti-inflammatory activity. Minecoside decreases CXCR4 expression and suppresses STAT3 activation, thus to inhibit CXCL 12-induced invasion. Minecoside potently inhibits cancer metastasis and promotes apoptotic progression.

8-Epideoxyloganic acid (7-Deoxy-8-epiloganic acid), an iridoid glucoside, can be found in Incarvillea delavayi. 8-Epideoxyloganic acid exhibits weak antinociceptive activity.

Chrysin (Standard) is the analytical standard of Chrysin. This product is intended for research and analytical applications. Chrysin is one of the most well known estrogen blockers.

Crenatoside is a phenylethanol glycoside compound that can be isolated from the ethyl acetate of the tree extract of T. stans var. stans with EC₅₀ value of 34.78 μM. Crenatoside has anti-Zika virus activity.

Dehydro-α-lapachone can be isolated from the methanol extract of stems of Catalpa ovata G Don. Dehydro-α-lapachone inhibits mycelial growth of Botrytis cinerea with IC₅₀ value 0.41 mg/L.

Icariside E4 is an antinociceptive agent, and can be isolated from Tabebuia roseo-alba. Icariside E4 has peripheral analgesic activity by ATP-sensitive K⁺ channel-dependent mechanisms. Icariside E4 also has anti-oxidant, anti-Alzheimer and anti-inflammatory effects.

Cleroindicin F ((-)-Rengyolone), a cleroindicin, is an antimicrobial agent. Cleroindicin F shows relatively high anticandidal activity against Candida strains with a MIC value down to 12.5 µg/mL.

5-Hydroxy-6,7-dimethoxyflavone is an orally active inhibitor of ferroptosis (Ferroptosis). 5-Hydroxy-6,7-dimethoxyflavone inhibits H1N1 virus-induced ferroptosis by upregulating the expression of SLC7A11 and GPX4. 5-Hydroxy-6,7-dimethoxyflavone alleviates inflammatory responses and inhibits apoptosis by suppressing the activation of the NF-κB and p38 MAPK signaling pathways. 5-Hydroxy-6,7-dimethoxyflavone can be used in studies related to H1N1 influenza virus infection.

6-O-p-Hydroxybenzoylglutinoside acts as a selective NF-κB inhibitor that suppresses the transcriptional activity of TNF-α-activated NF-κB (IC₅₀=52.78 μM). 6-O-p-Hydroxybenzoylglutinoside shows no significant inhibitory activity against sEH, AChE, or BChE. 6-O-p-Hydroxybenzoylglutinoside is a caged chlorinated iridoid glycoside identified from the seeds of Catalpa bungei (Manchurian catalpa).
