Vadimezan

SKU: orb1300915

Description

Vadimezan (DMXAA) is a murine STING agonist and vascular disrupting agent with antitumor activity. It selectively disrupts tumor blood flow and induces type I interferon, making it a valuable tool for studying cancer immunotherapy and vascular biology in both in vitro and in vivo models.

In Vivo
METHODS: To assay antitumor activity in vivo, Vadimezan (20 mg/kg) and BMS1166 (250 µg/mL) were injected intraperitoneally into Balb/c nude mice bearing DLBCL tumor LY1 once daily for eight days. RESULTS: Vadimezan and BMS1166 acted at effective concentrations. The combination treatment significantly inhibited the growth of GCB-like DLBCL cells compared to monotherapy. METHODS: To assay antitumor activity in vivo, Vadimezan (25,5,5,25 mg/kg; 25,0,0,25 mg/kg; 25,25,25,25 mg/kg) was administered intraperitoneally every three days to C57BL/6J mice bearing mouse mesothelioma AE17 for four doses. RESULTS: In group 1, 2/4 mice were cured, of which 2/4 showed long-term survival, but toxicity problems were observed. A better, less toxic response was observed in Group 2, with all four mice cured and showing long-term survival. In group 3, only 1 mouse was cured, but none showed long-term survival, possibly due to associated toxicity issues.

In Vitro
METHODS: DLBCL cells LY1 and LY3 were treated with Vadimezan (0-300 µM) for 24 h. Cell viability was measured by CCK-8 assay. RESULTS: Vadimezan treatment decreased the viability of DLBCL cells in a dose-dependent manner, with IC50s of 177 μM and 165 μM for LY1 and LY3, respectively. METHODS: Human lung cancer cells A549 were treated with Vadimezan (0.1-1 µM) for 24 h. The expression levels of target proteins were detected by Western Blot. RESULTS: Vadimezan induced a significant increase in the cytoplasmic level of cytochrome c and the activation of caspase 3, which ultimately led to apoptosis and death of A549 cells.

Cell Research
DLD-1 human colon carcinoma and H460 human non-small cell lung carcinoma cells are routinely maintained as monolayer cultures in RPMI 1640 culture medium supplemented with foetal calf serum (10%), sodium pyruvate (2 mM), penicillin/streptomycin (50 IU mL 1/50 μg mL-1) and l-glutamine (2 mM). Chemosensitivity is assessed using the MTT assay and all assays are performed under aerobic conditions. Briefly, cells are plated into each well of a 96-well culture plate and incubated overnight in an atmosphere containing 5% CO2. Culture medium is completely removed from each well and replaced with medium containing a range of drug concentrations. In the case of menadione alone, the duration of drug exposure is 1 hour, after which the cells are washed twice with Hanks' balanced salt solution prior to the addition of 200 μL fresh RPMI 1640 medium to each well of the plate. In the case of DMXAA alone, the duration of drug exposure is 3 hours. Following a four-day incubation, cell survival is determined using the MTT assay. For combinations of DMXAA with menadione, cells are initially set up and a non-toxic (>95% cell survival) concentration of DMXAA is selected. Cells are then initially exposed to DMXAA (2 mM) for a period of 2 hours, following which the medium is removed and replaced with medium containing the inhibitor (DMXAA at a constant concentration of 2 mM) and menadione (at a range of drug concentrations). Following a further 7-hour incubation, cells are washed twice with Hanks' balanced salt solution prior to the addition of growth medium.(Only for Reference)
