Sparstolonin B acts as a selective TLR2 and TLR4 antagonist and selectively blocks TLR2- and TLR4-mediated inflammatory signaling. Sparstolonin B has anti- HIV and anticancer activities
In Vitro
Sparstolonin B (1-20 µM; 2-4 days) inhibits cell growth and viability of neuroblastoma cells. Sparstolonin B inhibits TLR ligand-induced cytokine expression in mouse macrophages. Sparstolonin B inhibits MyD88 recruitment to TLR4 and TLR2. Sparstolonin B generates reactive oxygen species (ROS) in neuroblastoma cells. Sparstolonin B reduces expression of N-myc in neuroblastoma cells. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Viability AssayCell Line: SH-SY5Y, IMR-32, NGP, SKNF-1 and SK-N-BE(2) cells Concentration: 1 µM, 5 µM, 10 µM or 20 µM Incubation Time: 2-4 days Result: Effectively and dose-dependently inhibits the viability of all neuroblastoma cell lines after 2 days (SH-SY5Y and IMR-32), 3 days (NGP cells) or 4 days (SKNF-1 and SK-N-BE(2) cells) treatment.
In Vivo
Sparstolonin B (100 μg/mouse; i.p.) suppresses LPS-provoked inflammation in mice . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: 5-6-week-old male C57Bl/6 mice (body weight 18-20 g) Dosage: 100 μg/mouse Administration: I.p. Result: Significantly lower TNFα and IL-1β expression levels in LPS-induced sepsis mouse model.
