Overview

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

In Vitro

LV-320 (0-120 µM; SKBR3, MCF7, JIMT1, and MDA-MB-231 cells) treatment results in a dose-dependent increase in endogenous LC3B-II and protein p62 levels in all four cell lines. 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. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Western Blot AnalysisCell 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 AssayCell Line: MDA-MB-231 cells Concentration: 120 µM Incubation Time: 48 hours Result: Blocked autophagic flux.

In Vivo

LV-320 (100-200 mg/kg; oral gavage; three times over two days; GFP-LC3 mice) treatment results in 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 . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: GFP-LC3 mice (females, 9-14 weeks) 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.
