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].

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

Sparstolonin B (100 μg/mouse; i.p.) suppresses LPS-provoked inflammation in mice[1]. Animal Model: 5-6-week-old male C57Bl/6 mice (body weight 18-20 g)[1]
