The intestinal bile acid carrier ASBT (), the hepatic bile acid carrier NTCP (), and the steroid sulfate carrier SOAT (), all members of the solute carrier family SLC10, are established drug targets. The ASBT inhibitors odevixibat, maralixibat, and elobixibat are used to treat intrahepatic cholestasis, cholestatic pruritus, and obstipation. The peptide drug bulevirtide blocks binding of the hepatitis B and D viruses to NTCP and thereby inhibits the virus's entry into hepatocytes. Experimental SOAT inhibitors have antiproliferative effects on hormone-dependent breast cancer cells. The phenylsulfonylamino-benzanilide S1647 is an inhibitor of ASBT and SOAT. The present study aimed to comparatively analyze a set of newly synthesized and commercially available S1647 derivatives for their transport inhibition against ASBT, NTCP, and SOAT. Structure-activity relationships were systematically analyzed regarding potency and target specificity to elucidate whether this compound class is worth being further developed in preclinical studies for pharmacological ASBT, NTCP, and/or SOAT inhibition.
肠道胆汁酸载体 ASBT()、肝胆汁酸载体 NTCP()和甾体硫酸酯载体 SOAT()均属于溶质载体家族 SLC10,是已确立的药物靶点。ASBT 抑制剂奥贝胆酸、马洛胆酸和利昔胆酸用于治疗原发性胆汁性胆管炎、胆汁淤积性瘙痒和便秘。肽类药物布瓦西坦通过阻断乙型肝炎和丁型肝炎病毒与 NTCP 的结合,从而抑制病毒进入肝细胞。实验性 SOAT 抑制剂对激素依赖性乳腺癌细胞具有抗增殖作用。苯磺酰胺基苯甲酰胺 S1647 是 ASBT 和 SOAT 的抑制剂。本研究旨在比较分析一组新合成的和市售的 S1647 衍生物对 ASBT、NTCP 和 SOAT 的转运抑制作用。系统分析了构效关系,包括效力和靶标特异性,以阐明该化合物类是否值得在临床前研究中进一步开发用于药理学 ASBT、NTCP 和/或 SOAT 抑制。
