产品介绍
LV-320 是一种有效且非竞争性的ATG4B抑制剂,其IC50值为 24.5 μM,Kd值为 16 μM。 LV-320 抑制ATG4B的酶促活性,阻断细胞自噬,并且稳定无毒,在体内具有活性。

产品描述

LV-320 is a potent and uncompetitive ATG4B inhibitor with an IC 50 of 24.5 μM and a K d of 16 μM. LV-320 inhibits ATG4B enzymatic activity, blocks autophagic flux in cells, and is stable, non-toxic and active in vivo. These findings suggest that LV-320 will serve as a relevant chemical tool to study the various roles of ATG4B in cancer and other contexts [1].

体外活性

LV-320 (0-120 μM; SKBR3, MCF7, JIMT1, and MDA-MB-231 cells) treatment leads to a dose-dependent increase in endogenous LC3B-II and protein p62 levels in all four cell lines [1]. LV-320 (120 μM; 48 hours; MDA-MB-231 cells) treatment results in an increase in LC3B-II, indicating that LV-320 blocks autophagic flux [1]. Western Blot Analysis [1] Cell Line: SKBR3, MCF7, JIMT1, and MDA-MB-231 cells Concentration: 0 μM, 25 μM, 50 μM, 75 μM, 100 μM, or 120 μM Incubation Time: Result: Resulted in a dose-dependent increase in endogenous LC3B-II and protein p62 levels in all four cell lines. Cell Autophagy Assay [1] Cell Line: MDA-MB-231 cells Concentration: 120 μM Incubation Time: 48 hours Result: Blocked autophagic flux.

体内活性

LV-320 (100-200 mg/kg; oral gavage; three times over two days; GFP-LC3 mice) treatment leads to a terminal blood level of 169 μM and a liver level of 104 μM. The expression of GFP-LC3 puncta is significantly greater accumulation in LV-320 treated animals compared to controls. LC3B-II protein is also increased in LV-320-treated animals. The treatment do not cause significant toxicity in mice at either dose [1]. Animal Model: GFP-LC3 mice (females, 9-14 weeks) [1] Dosage: 100 mg/kg or 200 mg/kg Administration: Oral gavage; three times over two days (Pharmacokinetic study) Result: Terminal blood levels were 169 μM and liver levels were 104 μM. LC3B-II protein level was also increased.
