MedKoo Cat#: 200170 | Name: Alvespimycin HCl
Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Alvespimycin is an analogue of the antineoplastic benzoquinone antibiotic geldanamycin. Alvespimycin binds to HSP90, a chaperone protein that aids in the assembly, maturation and folding of proteins. Subsequently, the function of Hsp90 is inhibited, leading to the degradation and depletion of its client proteins such as kinases and transcription factors involved with cell cycle regulation and signal transduction. Check for active clinical trials or closed clinical trials using this agent.

Biological target:
Alvespimycin hydrochloride (17-DMAG hydrochloride; KOS-1022; BMS 826476) is an inhibitor of Hsp90, with EC50 of 62±29 nM.
In vitro activity:
Exposure of human SH-SY5Y neuroblastoma cells to 17-DMAG (10−11 to 10−8 m) for 24 h and 48 h did not affect cell viability as measured by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. However, 17-DMAG at concentrations of 10−7 to 10−5 m caused significant reductions in cell viability for 24 h and 48 h (P < 0.001) (Fig. 5A). In the subsequent experiments, concentrations of 17-DMAG were below 10 nm. As shown in Fig. 5B, after exposure to 2 μm rotenone for 48 h, the cell viability decreased by 30% compared to the control group (P < 0.001). Pretreatment with 17-DMAG at concentrations of 1 nm and 3 nm significantly attenuated rotenone-induced cell death (P < 0.05 and P < 0.01). This result suggested that 17-DMAG was effective in inhibiting rotenone-induced cell death. Reference: FEBS J. 2014 Feb;281(4):1110-22. https://pubmed.ncbi.nlm.nih.gov/24304935/
In vivo activity:
Consistent with past reports, this study found that hyperglycemia led to extensive HT in ischemic areas of the brain in MCAO model rats at 24 h post-MCAO. Relative to animals injected with vehicle control, animals administered 17-DMAG exhibited significant reductions in both infarct size and hemorrhage volume at 24 h post-MCAO (Figures 1(b)–1(d)). There was also a clear correlation between infarct size and hemorrhage volume in these animals (Figures 1(b)–1(d)). Relative to sham controls, MCAO model animals exhibited clear neurological deficits that were partially reversed in MCAO model animals that had been treated with 17-DMAG (Figure 1(e)).
