Product Introduction

Bioactivity
Description
3-O-Acetyl-16α-hydroxydehydrotrametenolic acid (3-O-Acetyl-16 alpha-hydroxydehydrotrametenolic acid) shows anti-inflammatory activity, it can inhibit NO production and iNOS expression in LPS-stimulated Raw264.7 cells.
In vitro
Based on bioassay-guided fractionation using lipopolysaccharide (LPS)-stimulated Raw264.7 cells, chemical investigation of the EtOH extract of the sclerotia of P. cocos resulted in the isolation and identification of eight compounds including six triterpenoids, namely poricoic acid A (1), 3-O-Acetyl-16 alpha-hydroxydehydrotrametenolic acid(2), polyporenic acid C (3), 3β-hydroxylanosta-7,9(11),24-trien-21-oic acid (4), trametenolic acid (5), and dehydroeburicoic acid (6), as well as (-)-pinoresinol (7) and protocatechualdehyde (8). The structures of the isolated compounds were determined by spectroscopic analysis, including 1H and 13C NMR spectra, and LC/MS analysis. The anti-inflammatory activities of the isolates were evaluated by estimating their effect on the production of nitric oxide (NO) and prostaglandin E2 (PGE2) in LPS-stimulated Raw264.7 as well as on the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). Compounds 1-5 inhibited NO production and iNOS expression in LPS-stimulated Raw264.7 cells. Among them, compound 1 exerted the highest anti-inhibitory activity and reduced PGE2 levels via downregulation of COX-2 protein expression.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg,each TargetMol | Animal experiments animal weighs 20 g, and the dosage volume is 100 μL. A total of TargetMol | Animal experiments 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL.
Mother liquor preparation method: 2 mg of drug dissolved in 50 μLDMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μLDMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μLTween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify.
