In vitro
Vemurafenib (PLX4032) inibisce B-RAFV600E, C-RAF, così come B-RAF wildtype, con IC50 di 31 nM, 48 nM e 100 nM, rispettivamente. Questo composto inibisce anche diverse chinasi non-RAF, tra cui ACK1, KHS1 e SRMS, con IC50 da 18 nM a 51 nM. Nelle linee cellulari di melanoma, l'effetto inibitorio dipende dallo stato mutazionale di B-RAF, poiché inibisce potentemente quelle che ospitano mutanti B-RAF V600, inclusi V600E, V600D, V600K e V600R, ma non il tipo wildtype o altri mutanti. I valori di IC50 su queste cellule, inclusi MALME-3M, Colo829, Colo38, A375, SK-MEL28 e A2058, vanno da 20 nM a 1 μM. In queste cellule, Vemurafenib (da 0,1 μM a 30 μM) inibisce anche la fosforilazione sia di MEK1/2 che di ERK1/2. È altamente efficace nel trattamento del melanoma, per la sua capacità di inibire B-RAFV600E. Tuttavia, questo composto mostra un effetto limitato nei pazienti con cancro del colon che portano anche l'oncoproteina B-RAFV600E. La ragione di ciò è che, nelle cellule di cancro del colon, l'inibizione di B-RAFV600E da parte di esso si traduce in una rapida attivazione di feedback dell'EGFR, che compensa la proliferazione cellulare inibita da PLX4032.
Saggio chinasico
Misurazioni dell'attività chinasica di RAF
Le attività chinasiche di RAF wild-type e mutanti sono determinate misurando la fosforilazione della proteina BAD biotinilata in presenza di Vemurafenib (PLX4032). Per ogni enzima (0,01 ng), vengono eseguite reazioni da 20 μL in 20 mM Hepes (pH 7,0), 10 mM MgCl2, 1 mM DTT, 0,01% (v/v) Tween-20, 50 nM di proteina biotina-BAD e 1 mM di ATP a temperatura ambiente. Le reazioni vengono interrotte a 5 minuti con 5 μL di una soluzione contenente 20 mM Hepes (pH 7,0), 200 mM NaCl, 80 mM EDTA, 0,3% (p/v) di albumina sierica bovina (BSA). La soluzione di arresto include anche anticorpi anti-fosfo-BAD (Ser112), perline donatrici rivestite di streptavidina e perline accettrici di proteina A. L'anticorpo e le perline vengono pre-incubati nella soluzione di arresto al buio a temperatura ambiente per 30 minuti. La diluizione finale dell'anticorpo è 1/2000 e la concentrazione finale di ogni perlina è 10 μg/mL. Le piastre del saggio vengono incubate a temperatura ambiente per un'ora e poi lette su un lettore PerkinElmer AlphaQuest. Le attività mutanti sono la media di due diversi lotti di proteine purificate saggiate in duplicato in tre diversi esperimenti.
In vivo
In modelli di xenotrapianto di topi mutanti B-RAFV600E, Vemurafenib (PLX4032) (6 mg/kg–20 mg/kg) inibisce la crescita tumorale. In modelli di xenotrapianto di topi con cellule LOX, Colo829 e A375, questo composto (12,5 mg/kg–100 mg/kg) inibisce la crescita tumorale e prolunga la sopravvivenza dei topi.

Domande Frequenti (Frequently Asked Questions)

Domanda 1:
How about its half-life?

Risposta:
It was reported that this compound has a half-life of 57 hours.

Domanda 2:
When prepared in 4% DMSO/30% PEG 300/5% Tween 80/ddH2O solutions, it forms a pellet down the tube?

Risposta:
When preparing this kind of vehicle, please dissolve it in DMSO clearly first. If it dissolves not readily, please sonicate and warm in the water bath at about 45 degree. Then add PEG and Tween. After they mixed homogeneously, then dilute with water.
