Indole-3-carboxaldehyde (3-Formylindole), a banlangen extract, is the product of the oxidative degradation of indole-3-acetic acid (IAA) by crude enzyme preparations from etiolated pea seedlings. Indole-3-carboxaldehyde is a biochemical used to prepare analogs of the indole phytoalexin cyclobrassinin. Indole-3-carboxaldehyde also enhances the epithelial barrier and anti-inflammatory activity in the intestinal tract.

Epigoitrin is a natural alkaloid that provides protection against influenza infection by reducing the host’s susceptibility to influenza virus under stress. Epigoitrin exerts antiviral activity against influenza A1 virus FM1 via inhibiting virus attachment and multiplication in vitro. Epigoitrin also has lipid-lowering effects.

Eupatorin is an orally active flavonoid with antiproliferative and vasodilatory properties. Eupatorin downregulates the expression levels of NF-κB, MMP9, IL-1β and TNF-α. Eupatorin induces apoptosis, G2/M phase cell cycle arrest, and reactive oxygen species (ROS) production. Eupatorin modulates the activities of muscarinic receptors and β-adrenergic receptors; inhibits sarcoplasmic reticulum calcium release and calcium channels; and activates the NO/sGC/cGMP pathway, indomethacin-sensitive pathway, and potassium channel pathway. Eupatorin exerts cytotoxic effects on cancer cell lines, and is metabolized by CYP1A1 and CYP1 family enzymes to form metabolites with antiproliferative activity. Eupatorin can be used in research related to breast cancer, hypertension, and leukemia.

Indole-3-carboxaldehyde (Standard) is the analytical standard of Indole-3-carboxaldehyde. This product is intended for research and analytical applications. Indole-3-carboxaldehyde (3-Formylindole), a banlangen extract, is the product of the oxidative degradation of indole-3-acetic acid (IAA) by crude enzyme preparations from etiolated pea seedlings. Indole-3-carboxaldehyde is a biochemical used to prepare analogs of the indole phytoalexin cyclobrassinin. Indole-3-carboxaldehyde also enhances the epithelial barrier and anti-inflammatory activity in the intestinal tract[1][2].

Clemastanin B, a lignin, has potent anti-influenza activities by inhibiting the virus multiplication, prophylaxsis and blocking the virus attachment. Clemastanin B targets viral endocytosis, uncoating or ribonucleoprotein (RNP) export from the nucleus. Clemastanin B has antioxidant and anti-inflammatory activities.

Caulilexin C is a phytoalexin from crucifers with antifungal activity.

Eupatorin (Standard) is the analytical standard of Eupatorin. This product is intended for research and analytical applications. Eupatorin, a naturally occurring flavone, arrests cells at the G2-M phase of the cell cycle and induces apoptotic cell death involving activation of multiple caspases, mitochondrial release of cytochrome c and poly(ADP-ribose) polymerase cleavage.

Epigoitrin (Standard) is the analytical standard of Epigoitrin. This product is intended for research and analytical applications. Epigoitrin is a natural alkaloid that provides protection against influenza infection by reducing the host’s susceptibility to influenza virus under stress. Epigoitrin exerts antiviral activity against influenza A1 virus FM1 via inhibiting virus attachment and multiplication in vitro. Epigoitrin also has lipid-lowering effects.

CI-39 is an antiviral natural product. CI-39 is an NNRTI (non-nucleoside reverse transcriptase inhibit) antiviral agent with an EC₅₀ of 3.40 μM and an CC₅₀ of >30 μM for wild type HIV-1. CI-39 inhibits HIV-1 RT DNA polymerase and ribonuclease H activitiessup.
