Home Apoptosis OXPHOS inhibitor - Autophagy activator - Mitochondrial Metabolism inhibitor VLX600 For research use only.

VLX600

VLX600 is a novel iron-chelating inhibitor of oxidative phosphorylation (OXPHOS), potentiates the effect of radiation in tumor spheroids in a synergistic manner. VLX600 shows enhanced cytotoxic activity under conditions of nutrient starvation. VLX600 induces autophagy and mitochondrial inhibition with antitumor activity.

Biological Activity

Description VLX600 is a novel iron-chelating inhibitor of oxidative phosphorylation (OXPHOS), potentiates the effect of radiation in tumor spheroids in a synergistic manner. VLX600 shows enhanced cytotoxic activity under conditions of nutrient starvation. VLX600 induces autophagy and mitochondrial inhibition with antitumor activity.
Targets
OXPHOS [2]
In vitro
In vitro

VLX600 shows enhanced cytotoxic activity under conditions of nutrient starvation.[1] Mitochondrial inhibition with VLX600 has a direct antitumor effect in vitro while appearing to promote glycolysis through increased AKT signaling and glucose transporter expression. When combined with imatinib, VLX600 prevents imatinib-induced cell cycle escape and reduces p27 expression, leading to increased apoptosis when compared to imatinib alone.[3]
Cell Research Cell lines human GIST-T1 cell line, human HG129 cell line, human GIST-882 cell line,
Concentrations 2 μM, 6 μM, 12 μM
Incubation Time 48–72h
Method

To measure cell viability, 1 × 104 GIST-T1, GIST-882, and HG129 cells are seeded in replicates of 5 in a 96-well flat-bottomed plate (Falcon) and cultured for 48–72h with VLX600 or DMSO-only solvent controls.
In Vivo
In vivo

VLX600 induces the formation of autolysosomes in vivo. VLX600 displays tumour growth inhibition in vivo.[1] When combined with imatinib, VLX600 reduces p27 expression in vivo, and prevents imatinib-induced cell cycle escape, likely potentiating the antitumoral effects of Kit inhibition.[3]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
