Brazilein
Based on 2 publication(s) in Google Scholar
Brazilein is a compound with anti-inflammatory and neuroprotective activities, with an IC50 of 500 μM against guinea pig Na+,K+-ATPase. Brazilein reduces iNOS mRNA expression, thereby inhibiting nitric oxide production in immune cells. Brazilein suppresses inflammatory responses by reducing the mRNA expression of TNF-α and IL-6, but has no effect on IL-1β expression. Brazilein reduces the cerebral infarction volume and improves the neurological function scores of rats with cerebral ischemia-reperfusion injury. Brazilein induces apoptosis of splenic lymphocytes in mice. Brazilein inhibits humoral immune responses in mice, and causes thymus and spleen atrophy as well as body weight loss in mice. Brazilein also possesses antimalarial and antibacterial activities. Brazilein is also a red dye. Brazilein can be used in studies related to the infection, nervous system, cardiovascular system and inflammatory diseases.

Brazilein (3.5-28 μM; 16 h) inhibits LPS (HY-D1056)-induced NO production in BV2 and RAW 264.7 cells, with IC50 values of 18.77 μM and 264.18 μM[1].
Brazilein (10-50 μM; 4 h) dose-dependently inhibits LPS-induced mRNA expression of iNOS, TNF-α and IL-6 in BV2 mouse microglia, but exerts no effect on the mRNA expression of IL-1β[1].
Brazilein (1-10 μg/mL; 72 h) dose-dependently inhibits Concanavalin A (HY-P2149)-induced proliferation of mouse splenic T lymphocytes, with an inhibition rate of 56.18% at 10 μg/mL (72 h), 27.25% at 5 μg/mL (72 h), and 10.67% at 1 μg/mL (72 h)[3].
Brazilein (1-10 μg/mL; 72 h) dose-dependently inhibits LPS-induced proliferation of mouse splenic B lymphocytes in vitro, with an inhibition rate of 68.38% at 10 μg/mL (72 h), 54.41% at 5 μg/mL (72 h), 46.69% at 2.5 μg/mL (72 h), and 26.11% at 1 μg/mL (72 h)[3].
Brazilein (1-10 μg/mL; 72 h) induces apoptosis of mitogen-stimulated mouse splenic lymphocytes in a dose-dependent manner in vitro[3].

Brazilein (1-48 mg/kg; intravenous injection; continuous infusion at 0.4 mL/kg/min) dose-dependently alters the electrocardiographic parameters of anesthetized guinea pigs, but does not induce ventricular arrhythmias even at the lethal dose of 48 mg/kg, which causes death via dyspnea[2].
Brazilein (12.5-50 mg/kg/day; intraperitoneal injection; 7 days) exhibits dose-dependent in vivo immunosuppressive activity in healthy mice[3].
