1. Heptaminol hydrochloride

Heptaminol hydrochloride  (Synonyms: RP-2831 hydrochloride)

Cat. No.: HY-B1231 Purity: ≥98.0%
COA Handling Instructions

Heptaminol (RP-2831) hydrochloride is a vasoconstrictor used in the study of hypotension, especially orthostatic hypotension. Heptaminol is also a skin cancer proliferation inhibitor that inhibits immune inflammation induced by the tumor promoting factor 12-O-tetradecanoylphorbol-13-acetate (TPA) in an NO-dependent manner. Heptaminol also acts as a sympathomimetic amine, exerting indirect sympathetic effects. Heptaminol is also an antagonist of catecholamine release and uptake and can increase intracellular free calcium levels.

Description

Heptaminol (RP-2831) hydrochloride is a vasoconstrictor used in the study of hypotension, especially orthostatic hypotension. Heptaminol is also a skin cancer proliferation inhibitor that inhibits immune inflammation induced by the tumor promoting factor 12-O-tetradecanoylphorbol-13-acetate (TPA) in an NO-dependent manner. Heptaminol also acts as a sympathomimetic amine, exerting indirect sympathetic effects. Heptaminol is also an antagonist of catecholamine release and uptake and can increase intracellular free calcium levels[1][2][3].

In Vivo

Heptaminol hydrochloride (12 μL; 50% water/acetone) stimulates NO synthesis from constitutive NOS and attenuates TPA-induced depletion of NK cells at the edge of the mouse ear. Heptaminol hydrochloride exerts anti-proliferative and anti-inflammatory effects on TPA, suggesting important anti-tumor function[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Acute TPA-induced inflammatory ear skin changes in Balb/c mouse (5-7 wk)[2]
Dosage: 2.5 nmol Heptaminol in 12 μL
Administration: Topical treatment for single dose; Heptaminol was dissolved in 50% water/acetone; 30 min before 0.4 nmol TPA (in 12 μL acetone) treatment.
Result: Stimulated NO production and directly inhibits tumors caused by TPA promoting inflammation.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
