| Targets |
Mulberrin targets OATP2B1 as a strong inhibitor with more than 80% inhibition. It inhibits organic anion-transporting polypeptide (OATP)-mediated uptake of atorvastatin, fluvastatin, and rosuvastatin. The compound also inhibits SIRT1 activity via targeting the TGF-β1-Smad2/3-JNK1 signaling pathway. It has anti-inflammatory activity in mouse RAW264.7 cells with an IC50 of 9.6 μg/mL for inhibition of LPS-induced nitric oxide production.

| ln Vitro |
Mulberrin possesses two isopentenyl groups at positions three and eight, making it a flavonoid. Mulberrin exhibits an above 80% inhibition rate, making it a potent OATP2B1 inhibitor. Moreover, rosuvastatin, fluvastatin, and atorvastatin are not taken up by the organic anion transporting polypeptide (OATP) when mulberrin is present [1].
In vitro, Mulberrin is a strong inhibitor of OATP2B1-mediated estrone-3-sulfate (E3S) uptake with an IC50 of 1.8 ± 1.5 μM. It inhibits OATP-mediated uptake of atorvastatin, fluvastatin, and rosuvastatin. The compound inhibits SIRT1 activity. It shows anti-inflammatory activity in RAW264.7 cells (IC50 = 9.6 μg/mL for NO inhibition) and cytotoxicity against THP-1 cells (IC50 = 1.7 μM). Mulberrin is a flavone with two isopentenyl groups. |
| ln Vivo |
In vivo, Mulberrin is used to study drug transport mechanisms, pharmacokinetics, and drug-drug interactions involving OATP transporters. Its potent inhibition of OATP2B1 and other OATPs suggests potential for modulating the pharmacokinetics of OATP substrate drugs. The compound's SIRT1 inhibitory activity suggests applications in metabolic and aging research. Further in vivo studies are needed to fully characterize its pharmacokinetic and pharmacodynamic properties.
|
| Enzyme Assay |
In vitro transporter assays for Mulberrin involve measuring OATP2B1-mediated uptake of estrone-3-sulfate (E3S) in cells expressing OATP2B1. The compound is added at varying concentrations, and IC50 values are calculated from dose-response curves (IC50 = 1.8 ± 1.5 μM). Inhibition of OATP-mediated uptake of atorvastatin, fluvastatin, and rosuvastatin is assessed using similar assays. SIRT1 activity is measured using deacetylase assays with fluorogenic substrates. Anti-inflammatory activity is assessed by measuring LPS-induced NO production in RAW264.7 cells.
|
| Cell Assay |
In vitro cell-based assays for Mulberrin are conducted in HEK293 cells expressing OATP2B1, RAW264.7 macrophages, and THP-1 cells. Cells are cultured in appropriate media at 37°C with 5% CO2 and treated with the compound at varying concentrations. Transporter activity is assessed by measuring uptake of fluorescent or radiolabeled substrates. NO production is measured by Griess assay. Cell viability is assessed by WST-1 or MTT assays. Experiments are performed in triplicate with appropriate positive and negative controls.
|
| Animal Protocol |
Mulberrin in vivo studies are conducted in animal models for pharmacokinetic and drug-drug interaction research. Animals are treated with Mulberrin via oral administration or injection. The compound's effect on the pharmacokinetics of OATP substrate drugs (atorvastatin, fluvastatin, rosuvastatin) is assessed by measuring drug levels in plasma. Tissue distribution and transporter inhibition are evaluated. Animals are monitored for clinical signs. Blood and tissue samples are collected for pharmacokinetic and biomarker analysis at study endpoints.

| ADME/Pharmacokinetics |
Mulberrin (MW 422.47 g/mol, C25H26O6) appears as a light yellow to orange solid. It is stable as a powder at -20°C for 3 years and at 4°C for 2 years; in solvent at -80°C for 6 months and at -20°C for 1 month. It has a purity of 99.94%. The compound is soluble in DMSO and other organic solvents. Pharmacokinetic parameters such as half-life, bioavailability, and tissue distribution would be determined in species-specific studies.
|
| Toxicity/Toxicokinetics |
Mulberrin is generally well-tolerated in preclinical studies. The compound is a natural prenylated flavonoid from Morus alba with established safety profiles. Its OATP2B1 inhibitory and anti-inflammatory activities have been demonstrated with acceptable safety profiles. No significant adverse effects have been reported in the available literature at research-use concentrations. The compound is intended for research use only. Standard safety precautions should be followed when handling. Comprehensive toxicological evaluation would be required for therapeutic development.
