Nafagrel [DP 1904, SR 96325] is a thromboxane A2 synthetase inhibitor that was undergoing clinical trials with Daiichi Seiyaku, now Daiichi Pharmaceutical, for the diabetic angiopathies, lupus nephritis and Raynaud's disease in Japan. However the development of Nafagrel has been discontinued.

Sample Use Guides

Japanese normal male volunteers received repeated oral doses of 200 mg every 12 h for 4 doses, or 400 mg every 24 h for 2 doses, or 200 mg every 12 h for 14 doses.
Route of Administration: Oral
In Vitro Use Guide
Curator's Comment: An augmented contraction and elevated thromboxane (TX) B2 release were observed, when the isolated parenchyma from Sephadex-treated rats was stimulated by 5-hydroxytryptamine (5-HT).
In the Sephadex-induced hyperresponsiveness model, Nafagrel at the concentrations of 3 x 10(-7) to approximately 3 x 10(-6) M, reduced the augmented contraction.
