N-(p-Coumaroyl) Serotonin
Based on 1 Customer Validation
N-(p-Coumaroyl) Serotonin is an orally active polyphenol found in safflower seeds with potent anti-inflammatory, antioxidant, and antitumor activities. N-(p-Coumaroyl) Serotonin suppresses NF‑κB, TLR4/MyD88 and MAPK signaling, activates NQO1/HO‑1 pathways, and inhibits pro‑inflammatory cytokines, iNOS and COX‑2 and ROS production. N-(p-Coumaroyl) Serotonin induces S‑phase arrest and apoptosis in glioblastoma cells, reduces atherosclerotic lesions, and alleviates renal and vascular injuries. N-(p-Coumaroyl) Serotonin acts as a vasodilator, regulates calcium dynamics. N-(p-Coumaroyl) Serotonin can be used for the research of neurodegenerative diseases, atherosclerosis, glioblastoma, and acute renal failure.

N-(p-Coumaroyl) Serotonin (CS) (12.5-100 μM, 1 h pre-incubation + 20 h LPS challenge) dose-dependently suppresses LPS-induced IL-6, TNF-α, MCP-1 secretion and NO production in BV2 microglia[1].
N-(p-Coumaroyl) Serotonin (12.5-100 μM) significantly inhibits LPS-induced signaling cascades in murine BV2 microglial cells. At 60 min post-LPS challenge, it dose-dependently suppresses the phosphorylation of p38, JNK, and ERK MAPKs, as well as the protein levels of TLR4 and MyD88. Furthermore, at 20 h post-LPS challenge, it robustly reduces the phosphorylation of IκBα and NF-κB p65 and inhibits the nuclear translocation of p65, thereby blocking the activation of the IκB/NF-κB signaling axis[1].

N-(p-Coumaroyl) Serotonin (50-200 μM; 72 h) induces dose-dependent S-phase cell cycle arrest and sub-G0/G1 phase accumulation (apoptosis) in U251MG and T98G glioblastoma cells[3].
N-(p-Coumaroyl) Serotonin (77 μM; 24 h) activates caspase-8 in U251MG glioblastoma cells[3].
N-(p-Coumaroyl) Serotonin (150-200 μM; 24 h) induces mitochondrial membrane depolarization in U251MG glioblastoma cells[3].
N-(p-Coumaroyl) Serotonin (50-200 μM; 72 h) induces dose-dependent increases in CD71 and CD15 expression in U251MG and T98G glioblastoma cells after 72 hours of treatment, while leaving CD24, CD44, and CD56 expression unchanged[3].
