In vitro
Abexinostat (PCI-24781) exhibits potent antitumor activity against a variety of tumor cell lines with GI50 ranging from 0.15 μM to 3.09 μM, and also has an antiproliferative effect on HUVEC endothelial cells with GI50 of 0.43 μM. Treatment with this compound causes dose-dependent accumulation of both acetylated histones and acetylated tubulin in HCT116 or DLD-1 cells, induces expression of p21, and leads to PARP cleavage and accumulation of the γH2AX. Inhibition of HDAC enzymes by PCI-24781 leads to a significant reduction in the transcription of genes specifically associated with HR, including RAD51. Consistent with inhibition of HR, it results in a decreased ability to perform homology directed repair of I-SceI-induced chromosome breaks in transfected CHO cells. It induces S phase depletion, G2 cell cycle arrest, and apoptosis in soft tissue sarcoma (STS) cells, and also causes Rad51 transcriptional repression in STS cells potentially mediated via enhanced E2F1 binding to the Rad51 proximal promoter. Additionally, this compound induces caspase and reactive oxygen species-dependent apoptosis through NF-κB mechanisms in Hodgkin lymphoma and non-Hodgkin lymphoma cell lines.
Kinase Assay
HDAC-activiteit
HDAC-activiteit wordt gemeten met behulp van een continue, trypsine-gekoppelde test. Voor de karakterisering van de remmer worden metingen uitgevoerd in een reactievolume van 100 μL met behulp van 96-wells assayplaten. Voor elk isozym wordt het HDAC-eiwit in reactiebuffer [50 mM HEPES, 100 mM KCl, 0,001% Tween 20, 5% DMSO (pH 7,4), aangevuld met runder serumalbumine in concentraties van 0% (HDAC1), 0,01% (HDAC2, 3, 8 en 10), of 0,05% (HDAC6)] gemengd met Abexinostat (PCI-24781) in verschillende concentraties en gedurende 15 minuten geïncubeerd. Trypsine wordt toegevoegd tot een uiteindelijke concentratie van 50 nM, en acetyl-Gly-Ala-(N-acetyl-Lys)-AMC wordt toegevoegd tot een uiteindelijke concentratie van 25 μM (HDAC1, 3 en 6), 50 μM (HDAC2 en 10), of 100 μM (HDAC8) om de reactie te starten. Negatieve controlereacties worden uitgevoerd in afwezigheid van deze verbinding in acht replicaten. Reacties worden gemonitord in een fluorescentieplaatlezer. Na een lagtijd van 30 minuten wordt de fluorescentie gedurende een tijdsbestek van 30 minuten gemeten met een excitatiegolflengte van 355 nm en een detectiegolflengte van 460 nm. De toename in fluorescentie met de tijd wordt gebruikt als maat voor de reactiesnelheid. Inhibitieconstanten Ki(app) worden verkregen met behulp van het programma BatchKi.
In vivo
Abexinostat (PCI-24781) was administered at 200 mg/kg once daily every other day (q.o.d.), which significantly inhibited the growth of HCT116 and DLD-1 xenografts in mice by 69% and 59%, respectively. In the HCT116 model, administration of this compound at 20 mg/kg, 40 mg/kg, 80 mg/kg, or 160 mg/kg once daily for 4 consecutive days followed by 3 days without treatment each week (q.d. × 4 per week) caused inhibition of tumor growth by 48%, 57%, 82.2%, or 80.0%, respectively.
