Werkingsmechanisme (Mechanism of Action)

Kenmerken	A synthetic derivative Geldanamycin, with lower hepatotoxicity than parent antibiotic & higher potency and bioavailability than the similar derivative 17-AAG.
Targets/IC₅₀/Ki	HSP90 (Cell-free assay) 62 nM
In vitro	Alvespimycin (17-DMAG) Hydrochloride vertoont ongeveer 2 keer zoveel potentie tegen humane Hsp90 dan 17-AAG, met een IC50 van 62 nM versus 119 nM. In SKBR3- en SKOV3-cellen die het Hsp90-clientproteïne Her2 overexpresseren, veroorzaakt Alvespimycin (17-DMAG) Hydrochloride down-regulatie van Her2 met een EC50 van respectievelijk 8 nM en 46 nM, evenals inductie van Hsp70 met een EC50 van respectievelijk 4 nM en 14 nM, wat leidt tot significante cytotoxiciteit met een GI50 van respectievelijk 29 nM en 32 nM, consistent met Hsp90-inhibitie. Alvespimycin (17-DMAG) Hydrochloride in combinatie met vorinostat induceert synergetisch apoptose van de gekweekte MCL-cellen evenals primaire MCL-cellen, krachtiger dan elk middel afzonderlijk, door de niveaus van cycline D1 en CDK4, evenals die van c-Myc, c-RAF en Akt, aanzienlijk te verzwakken. In tegenstelling tot 17-AAG, dat alleen actief is voor IKKβ in chronische lymfatische leukemie (CLL)-cellen, leidt behandeling met Alvespimycin (17-DMAG) Hydrochloride effectief tot depletie van het Hsp90-clientproteïne, wat resulteert in verminderde NF-κB p50/p65 DNA-binding, verminderde transcriptie van NF-κB-doelgenen en caspase-afhankelijke apoptose. Door zich op de NF-κB-familie te richten, medieert Alvespimycin (17-DMAG) Hydrochloride selectief dosis- en tijdsafhankelijke cytotoxiciteit tegen CLL-cellen, maar niet tegen normale T-cellen of NK-cellen die belangrijk zijn voor immuunsurveillance.
Kinase Assay	Fluorescentiepolarisatie (FP)-gebaseerde competitieve bindingsassay
Kinase Assay	Deze assay maakt gebruik van een boron difluoride dipyrromethene (BODIPY) gelabeld geldanamycine-analoog (BODIPY-AG) als sonde en meet fluorescentiepolarisatie bij binding van de sonde aan een eiwit. Native humaan Hsp90-eiwit (α + β isovormen) wordt geïsoleerd uit HeLa-cellen. De BODIPY-AG-oplossing wordt vers bereid in FP-assaybuffer (20 mM HEPES-KOH, pH 7.3, 1.0 mM EDTA, 100 mM KCl, 5.0 mM MgCl₂, 0.01% NP-40, 0.1 mg/mL vers rundvlees γ-globuline (BGG), 1.0 mM vers DTT, en protease-inhibitor van stockoplossing in DMSO). Competitiecurves worden verkregen door 10 μL van een oplossing die BODIPY-AG en Hsp90 bevat te mengen met een seriële verdunning van 17-DMAG, vers bereid in FP-assaybuffer vanuit een stockoplossing in DMSO. De eindconcentraties zijn 10 nM BODIPY-AG, 40 of 60 nM Hsp90, variërende concentraties van 17-DMAG (0.10 nM-10 μM), en ≤0.25% DMSO in een 384-well microplaat. Na incubatie van 3 uur bij 30 °C wordt de fluorescentie-anisotropie (γ_Ex = 485 nm, γ_Em = 535 nm) gemeten op een EnVision 2100 multilabel plaatreader. De IC50-waarde van 17-DMAG wordt verkregen uit de competitiecurves.
In vivo	De behandeling met Alvespimycin (17-DMAG) Hydrochloride aan 5 mg/kg of 25 mg/kg driemaal per week vermindert de tumorgroei van TMK-1 xenografts aanzienlijk door het vaatoppervlak en het aantal prolifererende tumorcellen in coupes significant te verlagen. In overeenstemming met de inhibitie van FAK signaling in vivo, onderdrukt de behandeling met Alvespimycin (17-DMAG) Hydrochloride aan 25 mg/kg driemaal per week de tumorgroei en metastase van ME180- en SiHa-xenografts bij muizen significant. Toediening van Alvespimycin (17-DMAG) Hydrochloride aan 10 mg/kg gedurende 16 dagen verlaagt het aantal witte bloedcellen aanzienlijk en verlengt de overleving in een TCL1-SCID transplantaat-muismodel.
