Vinaxanthone

Research use only, not for human use.

Vinaxanthone (SM-345431) is a small molecule compound derived from Penicillium chrysogenum that acts as a selective and potent inhibitor of semaphorin3A, phospholipase C (PLC), and FabI, exhibiting antimicrobial activity by blocking intracellular fatty acid synthesis and inhibiting the growth of Staphylococcus aureus.

Vinaxanthone (SM-345431) is a potent and selective semaphorin3A, phospholipase C (PLC) and FabI inhibitor, with IC50s of 0.1-0.2 μM and 0.9 mM for semaphorin3A and FabI. Vinaxanthone inhibits the substrate (t-o-NAC thioester) and the cofactor (NADPH) with Kis of 3.1 μM and 1.0 μM, respectively. Vinaxanthone can be used to handle infections caused by multidrug-resistant pathogens.

Cell Viability AssayCell Line:mouse corneal epithelial cell line (TKE2)Concentration:0.1 mg/mL Incubation Time:24 hResult:Didn't affect cell viability by dose.Cell Proliferation Assay Cell Line: TKE2 Concentration:0.01-1 mg/mL Incubation Time:24 h Result:Showed a slight dose-dependent inhibition on cell proliferation.Immunofluorescence Cell Line:mouse podocytes Concentration:0.5 μM Incubation Time:20 min Result:Exhibited less C-Caspase3-positive cells.Western Blot Analysis Cell Line:HK-2 cells Concentration:0.1-1 μM Incubation Time:24 h Result:Decreased the expression of E-cadherin.Increased the expression of ɑ-SMA and vimentin.

Animal Model:murine corneal transplantation modelDosage:0.1 mg/mLAdministration: Subconjunctival injections, every 2 days, 3 weeks Result:Showed significantly higher nerve growth.Improved the corneal sensitivity.Animal Model: mouse model of Doxorubicin (10 mg/kg)-induced podocytopathy Dosage:20 μg Administration:Intraperitoneal injection (i.p.), every day Result:Improved the expression of nephrin.Reduced podocytopathy and tubular casts.Detected rarely TUNEL-positive cells in the Dox + Vinaxanthone group.Had fewer p-c-Jun-positive cells in the Dox + Vinaxanthone group.
