Product Introduction

3',4',5',5,7-Pentamethoxyflavone is a naturally occurring brassinosteroid compound from the Rutaceae family that exhibits resistance to cancer cells by inhibiting the Nrf2 pathway to overcome chemotherapeutically active molecules.
In vitro
3',4',5',5,7-Pentamethoxyflavone (PMF), a natural flavonoid extracted from Rutaceae plants, sensitized A549/CDDP to CDDP and substantially induced apoptosis compared with that of CDDP alone treated group, and this reversal effect decreased when Nrf2 was downregulated by siRNA. Mechanistically, PMF reduced Nrf2 expression leading to a reduction of Nrf2 downstream genes, and in contrast, this effect was decreased by blocking Nrf2 with siRNA. Taken together, these results demonstrated that PMF could be used as an effective adjuvant sensitizer to increase the efficacy of chemotherapeutic drugs by downregulating Nrf2 signaling pathway.[1]
In vivo
The flavones tricin (4',5,7-trihydroxy-3',5'-dimethoxyflavone) and 3',4',5',5,7-Pentamethoxyflavone (PMF) are under development as potential colorectal cancer chemopreventive agents as they reduced adenoma development in the Apc(Min) mouse model of intestinal carcinogenesis. Plasma concentrations and area under the plasma concentration versus time curve for PMF were higher than those for tricin. A mono-O-desmethyl PMF and several isomeric mono-O-desmethyl PMF glucuronides and sulfonates were major PMF metabolites in murine plasma, liver and intestinal tissue. In murine and human liver fractions, in vitro metabolic removal of tricin was faster than that of PMF[1].

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.
