生物活性

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[1][2].

IC50 & Target[1][2]

TLR2

 

TLR4

 

HIV-1

 

体外研究
(In Vitro)

Sparstolonin B (1-20 µM; 2-4 days) inhibits cell growth and viability of neuroblastoma cells[3].
Sparstolonin B inhibits TLR ligand-induced cytokine expression in mouse macrophages. Sparstolonin B inhibits MyD88 recruitment to TLR4 and TLR2[1].
Sparstolonin B generates reactive oxygen species (ROS) in neuroblastoma cells. Sparstolonin B reduces expression of N-myc in neuroblastoma cells[3].

Cell Viability Assay[3]

Cell 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.

体内研究
