Meccanismo d'azione (Mechanism of Action)

Targets/IC₅₀/Ki	p21 HDAC (Cell-free assay) 32 nM
In vitro	Dacinostat (LAQ824) attiva l'espressione del gene che codifica l'inibitore del ciclo cellulare p21 attivando il promotore p21 con il 50% dell'attivazione massima del promotore (AC50) di 0,30 μM. Inibisce la crescita cellulare sia di H1299, una linea di carcinoma polmonare non a piccole cellule, sia di HCT116, una linea di cellule di cancro al colon con IC50 di 0,15 μM e 0,01 μM, rispettivamente, e l'effetto antiproliferativo di questo composto è selettivo verso le linee cellulari tumorali, inducendo solo l'arresto della crescita nei fibroblasti normali. Inoltre, induce un aumento dose-dipendente della proteina p21 nelle cellule A549 e un aumento dello stato ipofosforilato del soppressore tumorale Rb. Uno studio recente mostra che LAQ824 induce cambiamenti della cromatina a livello del promotore del gene IL-10 che portano a un maggiore reclutamento dei repressori trascrizionali HDAC11 e PU.1 e inibisce la produzione di IL-10 nei macrofagi murini BALB/c.
Saggio chinasico	Saggio di istone deacetilasi in vitro
Saggio chinasico	Gli enzimi HDAC vengono parzialmente purificati dal lisato cellulare H1299 mediante cromatografia a scambio ionico utilizzando la colonna Q Sepharose Fast Flow. I complessi enzimatici vengono raccolti da 500 mg di lisato cellulare totale mediante immunoprecipitazione con anticorpo policlonale cdk2 o anticorpo monoclonale cdk1/cdc2. Gli immunocomplessi vengono risospesi in tampone per chinasi (50 mM Hepes, pH 8, 10 mM MgCl₂, 2,5 mM EDTA, 1 mM ditiotreitolo, 20 mM ATP, 10 mM β-glicerofosfato, 0,1 mM NaVO₄, 1 mM fluoruro di sodio, 50 mM ATP, 10 μCi di [γ-³²P]ATP) insieme a 1 μg di substrato proteico ricombinante pRb (cdk2) o 10 mL di miscela di istoni H1 contenente 20 μg di substrato (cdc2). Le istoni Rb e H1 fosforilate vengono risolte mediante elettroforesi e quantificate utilizzando un PhosphorImager. Questo composto, Dacinostat (LAQ824), viene utilizzato nel saggio.
In vivo	Dacinostat (LAQ824) produce effetti inibitori sulla crescita tumorale in modo dose-dipendente senza citotossicità generale in HCT116 e xenotrapianti di tumori del colon umano in topi nudi quando somministrato a 100 mg/kg.
