生物活性

JMV7048 is an effective PROTAC degrader targeting PXR (Pregnane X Receptor) with a DC50 of 379 nM. JMV7048 induces the polyubiquitination and degradation of PXR protein by recruiting E3 CRBN ubiquitin ligase and the 26S proteasome. JMV7048 significantly enhances the sensitivity of colon cancer stem cells to chemotherapy by reducing the expression of PXR protein in these cells, thereby significantly delaying cancer recurrence in vivo. JMV7048 is composed of the PXR agonist JMV6944 (HY-162738), linker (HY-162736), and Thalidomide 5-fluoride (HY-W087383) (Red: JMV6944; Blue: Thalidomide 5-fluoride ligand; Black: linker)[1].

Pregnane X Receptor (PXR)

体外研究
(In Vitro)

JMV7048 (5 µM, 24 小时) 对结肠癌、肝癌和胰腺癌细胞系的癌细胞生长具有抑制作用[1]
JMV7048 (5 µM, 48 小时) 可显著降低移植入裸鼠的 CPP1 细胞的致瘤性 (即降低裸鼠中肿瘤起始的频率)[1]
JMV7048 (5 µM, 48 小时) 降低 CPP1、CPP14 和 CPP19 细胞在非附着条件下形成球体的能力,表明 JMV7048 能够影响这些细胞的自我更新能力[1]
JMV7048 (5 µM, 48 小时) 处理显著降低了 HT29 细胞在化疗药物 (5-Fluorouracil (HY-90006) 和 SN38 (HY-13704)) 处理后的存活率,表明 JMV7048 可能增强了细胞对化疗药物的敏感性[1]

Western Blot Analysis[1]

Cell Line: LS174T cells (human colon adenocarcinoma); HepG2 (human hepatoma); AsPC-1 (human metastatic pancreatic adenocarcinoma), Human hepatocytes
Concentration: 0-5000 nM, 5 μM
Incubation Time: 24 h (0-5000 nM), 0-6 h (5 μM)
Result: Potently and efficiently reduced endogenous PXR protein in LS174T cells (0-5000 nM, 24 h or 5 μM, 0-6 h).
Significantly reduced the expression of PXR in HepG2 cells and AsPC-1 cells (at the dose of 5 μM, 24 h).
Failed to degrade PXR in primary cultures of human hepatocytes (at the dose of 5 μM, 24 h).

Cell Viability Assay[1]

Cell Line: LS174T cells, HT29 cells, CPP1 cells, CPP14 cells, CPP19 cells, CRC1 cells
Concentration: 0-20 µM
Incubation Time: 72 h
Result: Resulted in no significant change in cell viability after 72 hours of treatment at concentrations as high as 20 μM, compared to treatment with the active metabolite of irinotecan (HY-16562) (SN38(HY-13704)).
体内研究
(In Vivo)

JMV7048 (25 mg/kg,静脉注射,1 天 1 次,每周 5 天,共 15 天) 在无胸腺裸鼠和 NOD/scid 小鼠中耐受性良好[1]
JMV7048 (25 mg/kg,静脉注射,1 天 1 次,持续 4 天或每周 5 天持续 2 周) 在 HT29 和 CCP1 来源的 NOD/scid 小鼠异种移植瘤模型中显示出降解 PXR 的活性[1]
联合使用 JMV7048 (25 mg/kg,静脉注射,1 天 1 次,每周 5 天,共 4 周 (HT29 细胞); 25 mg/kg,腹腔注射,1 天 2 次,每周 5 天,共 3 周 (CCP1 细胞)) 与化疗药物 (50mg/kg 5-Fluorouracil (HY-90006) + 25mg/kg Irinotecan (HY-16562),腹腔注射,每周 2 次,3 或 4 周),在 NOD/scid 小鼠异种移植 (LS174T 细胞) 模型中可以显著延缓肿瘤复发[1]
单次腹腔注射 (50 mg/kg) 或静脉注射 (25 mg/kg) 的给药方式能在血浆中实现充分的药物暴露水平,而口服灌胃 (50 mg/kg) 给药方式则显著低效[1]

药代动力学分析[1]

JMV7048 AUC (μg/L*h) Tmax (min) Cmax (μg/mL)
i.v. (25 mg/kg) 5.19 5 15.4
i.p. (30 mg/kg) 10.55 30 2
p.o. (25 mg/kg) 0.07 30 0.02

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: HT29 and CCP1-derived xenograft tumor models in NOD/scid mice
Dosage: 25 mg/kg
Administration: Intraperitoneal injection (i.p.), Intravenous injection (i.v.), 5 days a week
Result: Significantly delayed tumor relapse and extended tumor volume doubling time.
Animal Model: HT29 and CCP1-Derived Xenograft Tumor Models in NOD/scid Mice
Dosage: 25 mg/kg
Administration: Intravenous injection (i.v.), once daily for 4 days or 5 days a week for 2 weeks
Result: significantly reduced (approximately 50%) the expression of PXR in xenograft tumors, suggesting that JMV7048 maintains PXR-degrading activity in vivo.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
