Wirkmechanismus (Mechanism of Action)

Targets/IC₅₀/Ki	HDAC1 (Cell-free assay) 7 nM(Ki) HDAC3/SMRT 8.2 nM(Ki) HDAC6 17 nM(Ki) HDAC2 (Cell-free assay) 19 nM(Ki) HDAC10 24 nM HDAC8 280 nM
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 Aktivität
Kinase-Assay	Die HDAC-Aktivität wird unter Verwendung eines kontinuierlichen Trypsin-gekoppelten Assays gemessen. Für die Inhibitorkarakterisierung werden Messungen in einem Reaktionsvolumen von 100 μL unter Verwendung von 96-Well-Assay-Platten durchgeführt. Für jedes Isoenzym wird das HDAC-Protein in Reaktionspuffer [50 mM HEPES, 100 mM KCl, 0,001% Tween 20, 5% DMSO (pH 7,4), ergänzt mit Rinderserumalbumin in Konzentrationen von 0% (HDAC1), 0,01% (HDAC2, 3, 8 und 10) oder 0,05% (HDAC6)] mit Abexinostat (PCI-24781) in verschiedenen Konzentrationen gemischt und 15 Minuten inkubiert. Trypsin wird zu einer Endkonzentration von 50 nM hinzugefügt, und Acetyl-Gly-Ala-(N-acetyl-Lys)-AMC wird zu einer Endkonzentration von 25 μM (HDAC1, 3 und 6), 50 μM (HDAC2 und 10) oder 100 μM (HDAC8) hinzugefügt, um die Reaktion zu initiieren. Negativkontrollreaktionen werden in Abwesenheit dieser Verbindung in acht Replikaten durchgeführt. Die Reaktionen werden in einem Fluoreszenz-Plattenlesegerät überwacht. Nach einer 30-minütigen Verzögerungszeit wird die Fluoreszenz über einen Zeitraum von 30 Minuten unter Verwendung einer Anregungswellenlänge von 355 nm und einer Detektionswellenlänge von 460 nm gemessen. Die Zunahme der Fluoreszenz mit der Zeit wird als Maß für die Reaktionsrate verwendet. Hemmkonstanten K_i(app) werden mit dem Programm BatchKi erhalten.
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.
