生物活性

製品説明	Brequinar is an inhibitor of dihydroorotate dehydrogenase (DHODH) with an IC50 of ∼20 nM in vitro.
in vitro	Brequinar sodium (BQR) reduces of PyN levels in Con A-stimulated T cells and inhibition of cell proliferation at low concentrations, which can be reversed by uridine. However, uridine is unable to reverse the effects of high concentrations of BQR. BQR possesses the ability of inhibiting tyrosine phosphorylation.^[2]
in vivo	Brequinar sodium (BQR) induces anemia through inhibition of DHO-DHase activity and de novo pyrimidine synthesis in vivo. Coadministration of BQR with uridine prevents anemia.^[2]

細胞アッセイ	細胞株	splenic T cells isolated from BALB/c mice
	濃度	0.26, 1.3, 2.6 μM
	反応時間	40-66 h
	実験の流れ	Lymphocytes are isolated from BALB/c spleen by centrifugation through a Ficol gradient and are depleted of macrophages and B cells by adherence to goat anti-mouse IgG-coated plates. The nonadherent cells are harvested and cultured at 4 to 5× 10⁵/ml in RPMI 1640 supplemented with 10% FBS. Stimulation is performed with 5 μg/ml Con A in the presence of indicated concentrations of Brequinar or uridine. After 40 to 66 h, the cells are harvested and the levels of cell proliferation or purine NTP and PyNTP are quantified.
