产品详情
生物活性:
MSC-4381 (MCT4-IN-1) is an orally active and selective monocarboxylate transporter 4 (MCT4/SLC16A3) inhibitor with an IC50 of 77 nM and a Ki of 11 nM. MSC-4381 targets to the cytosolic domain of MCT4. MSC-4381 results in lactate efflux inhibition and reduction of cellular viability in MCT4 high expressing cells. MSC-4381 has the potential for MCT4 transporter inhibition research. MSC-4381 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

体内研究:
MSC-4381 (化合物 18n;30 mg/kg;口服单剂量) 仅与 MCT1/2 抑制剂联合使用时表现出显著的肿瘤细胞内乳酸积累。 MSC-4381 (30 mg/kg/天;持续 15 天) 未显示出显著的抗肿瘤活性。 MSC-4381 (0.2 mg/kg;iv) 的 T1/2 为 1 小时,CL 为 0.33 L/h kg,Cmax 为 489 ng/mL,小鼠的 Vss 为 0.4 L/kg。Animal Model:MC38 tumor-bearing C57/BL6 mice
Dosage:30 mg/kg
Administration:PO; single dose
Result:Only combined with MCT1/2 inhibitor exhibited a significant tumoral intracellular lactate accumulation.
Animal Model:Mice
Dosage:0.2 mg/kg (Pharmacokinetic Analysis)
Administration:IV
Result:Had a T1/2 of 1 hours, a CL of 0.33 L/h?kg, a Cmax of 489 ng/mL and a Vss of 0.4 L/kg for mice.

体外研究:
MSC-4381 (化合物 18n) 抑制 MDA-MB-231 细胞系中的乳酸流出,IC50 为 1 nM。通过荧光互相关光谱 (FCCS) 确认了靶向活性,Ki 为 11 nM。 MSC-4381 在 SNU-398 和 MiaPaca2 中对乳酸流出的抑制程度相似,在 RT-4 细胞系中仅低 600 倍。
