(+)-JQ1 Inibitore di BET

N. Cat.S7110

(+)-JQ1 è un inibitore del bromodominio BET, con IC50 di 77 nM/33 nM per BRD4(1/2) in saggi acellulari, che si lega a tutti i bromodomini della famiglia BET, ma non ai bromodomini al di fuori della famiglia BET. Il (+)-JQ1 sopprime la proliferazione cellulare inducendo l'autophagy. Il (+)-JQ1 inibisce l'espressione dei geni bersaglio della Nuclear receptor binding SET domain protein 3 (NSD3).

Metodo per preparare il liquido master di DMSO: mg farmaco predissolto in μL DMSO ( Concentrazione del liquido master mg/mL, Vi preghiamo di contattarci prima se la concentrazione supera la solubilità del DMSO del lotto del farmaco. )

Metodo per preparare la formulazione in vivo: Prendere μL DMSO liquido master, quindi aggiungereμL PEG300, mescolare e chiarire, quindi aggiungereμL Tween 80, mescolare e chiarire, quindi aggiungere μL ddH2O, mescolare e chiarire.

Metodo per preparare la formulazione in vivo: Prendere μL DMSO liquido master, quindi aggiungere μL Olio di mais, mescolare e chiarire.

Nota: 1. Si prega di assicurarsi che il liquido sia limpido prima di aggiungere il solvente successivo.
2. Assicurarsi di aggiungere il/i solvente/i in ordine. È necessario assicurarsi che la soluzione ottenuta, nell'aggiunta precedente, sia una soluzione limpida prima di procedere all'aggiunta del solvente successivo. Metodi fisici come il vortex, gli ultrasuoni o il bagno d'acqua calda possono essere utilizzati per facilitare la dissoluzione.

In vitro
L'enantiomero (+)-JQ1 si lega direttamente al sito di legame Kac dei bromodomini BET. Questo composto (500 nM) si lega a BRD4 in modo competitivo con la cromatina, con conseguente differenziazione e arresto della crescita delle cellule NMC. Questa sostanza chimica (500 nM) attenua la rapida proliferazione delle linee cellulari NMC 797 e Per403, come dimostrato dalla ridotta colorazione di Ki67. Questo composto (500 nM) diminuisce potentemente l'espressione di entrambi i geni bersaglio di BRD4 nelle cellule NMC 797. Inibisce la vitalità cellulare con IC50 di 4 nM nelle cellule NMC 11060. Porta a una robusta inibizione dell'espressione di MYC nelle linee cellulari di MM. Questo composto inibisce la proliferazione di KMS-34 e LR5 con IC50 di 68 nM e 98 nM, rispettivamente. Le cellule MM.1S trattate con questa sostanza chimica (500 nM) mostrano una marcata diminuzione della proporzione di cellule in fase S, con un concomitante aumento delle cellule arrestate in G0/G1. Esso (500 nM) provoca una pronunciata senescenza cellulare mediante colorazione della beta-galattosidasi. L'esposizione a questo composto (800 nM) porta a una significativa riduzione della vitalità cellulare nella maggior parte dei campioni di MM derivati da pazienti CD138+ testati. Inibisce la crescita delle cellule LP-1 con GI50 di 98 nM. Questa sostanza chimica (625 nM) determina un aumento della percentuale di cellule LP-1 in G0/G1. Essa (500 nM) sopprime l'espressione di MYC, BRD4 e CDK9 nelle cellule LP-1. Questo composto (1 μM) attiva la trascrizione dell'HIV nelle cellule T Jurkat infette in modo latente. Esso (50 μM) stimola prevalentemente la trascrizione dell'HIV dipendente da Tat sia nelle cellule Jurkat che HeLa. Questa sostanza chimica (5 μM) induce la dissociazione di Brd4 che consente a Tat di reclutare SEC al promotore dell'HIV e indurre la fosforilazione del CTD della Pol II e la trascrizione virale nelle cellule J-Lat A2. Permette a Tat di aumentare la fosforilazione del T-loop di CDK9 e dissocia parzialmente P-TEFb da 7SK snRNP nelle cellule T Jurkat.
In vivo
(+)-JQ1 (50 mg/kg) inibisce la crescita tumorale nei topi con xenotrapianti NMC 797. Questo composto provoca l'eradicazione delle macchie nucleari NUT nei topi con xenotrapianti NMC 797, coerentemente con il legame competitivo alla cromatina nucleare. Induce una forte espressione della cheratina (grado 31) negli xenotrapianti NMC 797. Questa sostanza chimica promuove la differenziazione, la regressione tumorale e la sopravvivenza prolungata in modelli murini di xenotrapianti NMC. Porta a un significativo prolungamento della sopravvivenza globale di topi SCID-beige xenotrapiantati ortotopicamente dopo iniezione endovenosa con cellule MM.1S-luc+ rispetto agli animali trattati con veicolo. Questo composto porta a un aumento altamente significativo della sopravvivenza dei topi portatori di xenotrapianti Raji.

Domande Frequenti (Frequently Asked Questions)

Domanda 1:
How can I reconstitute it for in vivo injection?

Risposta:
It does not dissolve in water/PBS. The vehicle we recommend is 2% DMSO+30% PEG 300+5% Tween 80+ddH2O. This compound can be dissolved in the vehicle at 5mg/ml and you can use it for IV injection.
