生物活性

ABS-752 is an orally active prodrug of CRBN-modulating molecular glue targeting. ABS-752 can effectively degrade GSPT1. ABS-752 can degrade NEK7. ABS-752 does not form ternary complexes with CRBN and the neosubstrates. ABS-752 is a prodrug activated by the monoamine oxidase, VAP-1, to an aldehyde intermediate and subsequently to the active molecule, ABT-002. ABS-752 can be used for the study of hepatocellular carcinoma (HCC)[1].

IC50 & Target[1]

GSPT1

 

体外研究
(In Vitro)

ABS-752 (6-24 小时) 可降解 Hep3B 细胞中的 GSPT1、NEK7 和 CK1α,以及 Kelly 细胞中的 SALL4,但不会降解 H929 细胞中的 IKZF1[1]
ABS-752 (0.01-10 μM,48-72 小时) 主要通过 GSPT1 对 Hep3B 细胞发挥细胞毒性[1]
ABS-752 (0.1-10 μM,24 小时) 可诱导 Hep3B 野生型细胞中 NEK7 的降解,且该降解现象在 G575N 突变体中仍然存在[1]
PXS-4728A 可消除 ABS-752 (0.1 nM-30 μM,72 小时) 在 Hep3B 和 KG-1 细胞系中的活性及其对靶蛋白的下调作用[1]
ABS-752 (0.1 nM-30 μM,72 小时) 在添加 FBS 的培养基中显著降低了 Hep3B 和 KG-1 细胞的活力,但在添加人血清的培养基中则没有这种效果[1]

Western Blot Analysis[1]

Cell Line: Hep3B cells, G575N mutant Hep3B cells
Concentration: 0.01 μM, 0.1 μM, 1 μM, 10 μM
Incubation Time: 48 h
Result: In G575N mutant Hep3B cells, GSPT1 is not degraded; however, in wild-type Hep3B cells, GSPT1 is effectively degraded.
体内研究
(In Vivo)

ABS-752 (1-10 mg/kg, p.o., twice daily for 14 days) exhibits potent antitumor activity in a Hep3B cell xenograft mouse model and degraded GSPT1 and NEK7 in tumor tissue[1].
ABS-752 (100 mg/kg, p.o., twice daily for 20-21 days) effectively inhibits tumor growth in a human hepatocellular carcinoma patient-derived liver cancer xenograft mouse model[1].

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

Animal Model: Female NSG mice subcutaneously implanted with Hep3B human liver cancer cell line[1].
Dosage: 1 mg/kg, 3 mg/kg, 10 mg/kg
Administration: P.o., twice daily for 14 days
Result: The 10 mg/kg group showed complete tumor regression.
The 3 mg/kg and 1 mg/kg groups showed significant and moderate tumor growth inhibition, respectively.
GSPT1 and NEK7 degradation was observed in the tumor samples.
Animal Model: 10 Subcutaneous patient-derived liver cancer xenograft (PDX) models were developed in female BALB/c nude mice[1].
Dosage: 100 mg/kg
Administration: P.o., twice daily for 20-21 days
Result: Of the 10 PDX models, 8 showed tumor growth inhibition, with 4 of them having a TGI >50%.

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.
