Indican (Indoxyl-β-D-glucoside) 是吲哚酚的一种糖苷，染料靛蓝和靛玉红的前体。它的主要代谢物是硫酸吲哚酚 (IS)。其中 IS 是尿毒症毒素，是有机阴离子转运蛋白1 (OAT 1)、OAT 3 和多药耐药相关蛋白4 (MRP 4) 的底物 抑制剂。

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。

PU 23 是一种多药抗性蛋白4(MRP4)的抑制剂。

MK-571 sodium (L-660711 sodium salt) 是一种可口服的选择性白三烯 D4受体拮抗剂，在豚鼠和人肺膜的 Ki 分别为0.22 和 2.1 nM。

Estradiol 17-(β-D-glucuronide) (E217G) is an estrogen metabolite formed in the liver and subsequently excreted in bile.1It acts as a substrate of the multidrug resistance protein 2 (MRP2; Km= 75 μM), and through MRP2-mediated transport, functions as a cholestatic agent, decreasing bile flow.1,2In addition to binding to the MRP2 transport site, E217G has been shown to bind to an allosteric site that through positive cooperativity activates its own transportviaMRP2 and the transport of other MRP2 substrates, including the non-cholestatic estrogen metabolite, estradiol 3-(β-D-glucuronide) .2,3E217G has also been reported to be transported by MDR1, MRP1, MRP3, MRP4, MRP7, ABCG2 (a breast cancer resistance protein transporter), and the rat organic anion-transporting polypeptides 1-4.2 1.Loe, D.W., Almquist, K.C., Cole, S.P., et al.ATP-dependent 17β-estradiol 17-(β-D-glucuronide) transport by multidrug resistance protein (MRP).
