Ceefourin 1 是一种具有高度选择性的多药抗性蛋白 4 (MRP4) 抑制剂。它能够抑制多种 MRP4 底物的转运，但对其他 ABC 转运蛋白无影响。它是苯并噻唑，常作为高危神经母细胞瘤的化学增敏剂。

Ceefourin 1 is a highly selective multidrug resistance protein 4 (MRP4) inhibitor.

Ceefourin 1 and Ceefourin 2, that inhibit transport of a broad range of MRP4 substrates, yet are highly selective for MRP4 over other ABC transporters, including P-glycoprotein (P-gp), ABCG2 (Breast Cancer Resistance Protein;?BCRP) and MRP1 (multidrug resistance protein 1;?ABCC1).?Both compounds are more potent MRP4 inhibitors in cellular assays than the most widely used inhibitor, MK-571, requiring lower concentrations to effect a comparable level of inhibition.?Furthermore, Ceefourin 1 and Ceefourin 2 have low cellular toxicity, and high microsomal and acid stability.
