15 nM
In vitro
Tubastatin A es selectivo en todas las isozimas excepto HDAC8 y mantiene una selectividad más de 1000 veces mayor contra todas las isoformas excluyendo HDAC8, donde tiene aproximadamente 57 veces más selectividad. Este compuesto induce preferentemente la hiperacetilación de α-tubulina a 2.5 μM. Se observa una ligera inducción de la hiperacetilación de histonas para este químico a 10 μM. Muestra una protección dosis-dependiente contra la muerte celular neuronal inducida por ácido homocisteico, comenzando a 5 μM con una protección casi completa a 10 μM. Este compuesto (10 μM) induce un aumento en los niveles de α-tubulina acetilada y la restauración de la expresión de cilios primarios en las líneas celulares de colangiocarcinoma (18 veces); y la restauración de los cilios primarios se correlacionó con la regulación a la baja de las vías de señalización Hedgehog (Hh) y MAPK, así como con la disminución de las tasas de proliferación celular (en promedio un 50%) y la invasión (un 40%). Muestra una inhibición significativa de TNF-α e IL-6 en macrófagos THP-1 humanos estimulados por LPS con una IC50 de 272 nM y 712 nM. Este inhibidor inhibe la secreción de óxido nítrico (NO) en macrófagos murinos Raw 264.7 de forma dosis-dependiente con una IC50 de 4.2 μM.
Ensayo de quinasa
Ensayos enzimáticos de HDAC
Tubastatin A se disuelve y diluye en tampón de ensayo (50 mM HEPES, pH 7.4, 100 mM KCl, 0.001% Tween-20, 0.05% BSA y 20 μM tris(2-carboxietil)fosfina) a 6 veces la concentración final. Las enzimas HDAC se diluyen a 1.5 veces la concentración final en tampón de ensayo y se preincuban con este compuesto durante 10 minutos antes de la adición del sustrato. La cantidad de FTS (HDAC1, HDAC2, HDAC3 y HDAC6) o MAZ-1675 (HDAC4, HDAC5, HDAC7, HDAC8 y HDAC9) utilizada para cada enzima es igual a la constante de Michaelis (Km), según lo determinado por una curva de titulación. FTS o MAZ-1675 se diluye en tampón de ensayo a 6 veces la concentración final con 0.3 μM de tripsina de grado de secuenciación. La mezcla de sustrato/tripsina se añade a la mezcla de enzima/compuesto y la placa se agita durante 60 segundos y luego se coloca en un lector de microplacas SpectraMax M5. La reacción enzimática se monitoriza para la liberación de 7-amino-4-metoxi-cumarina durante 30 minutos, después de la desacetilación de la cadena lateral de lisina en el sustrato peptídico, y se calcula la tasa lineal de la reacción.
In vivo
Tubastatin A reduce el crecimiento del colangiocarcinoma in vivo. Este compuesto (10 mg/kg) induce pesos tumorales medios 6 veces menores en un modelo ortotópico de rata singénica de colangiocarcinoma, y una reducción de las relaciones peso tumoral/peso hepático y peso corporal (5 y 5.6 veces, respectivamente), así como una mayor frecuencia de colangiocitos ciliados en comparación con los controles (29% frente a 1.4%). Disminuye significativamente la cantidad de células PCNA-positivas en los tumores tratados en comparación con los controles vehiculares (34% frente a 65%). Este químico muestra una inhibición significativa del volumen de la pata a 30 mg/kg i.p. en un modelo animal de inflamación inducida por el adyuvante completo de Freund (FCA). A 30 mg/kg i.p., atenúa significativamente las puntuaciones clínicas (~ 70%) y la expresión de IL-6 en los tejidos de la pata de ratones DBA1 con artritis inducida por colágeno.

Preguntas frecuentes

Pregunta 1:
We are planning to order some, but I found out there are two versions of it. One has HCl and one does not. Which one do you recommend for live cell use? Will the HCl containing version significantly change the pH?

Respuesta:
S8049 and S2627 have the same molecular structure. The only difference is S2627 containing HCl and has higher solubility in DMSO (74 mg/mL vs. S8049 9 mg/mL). Since they are the same molecule, its biological function should be similar. I would recommend to use S2627 for cell culture study.

Pregunta 2:
What vehicle do you recommend to dissolve it for in vivo experiments?

Respuesta:
It can be dissolved in 2% DMSO/30% PEG 300/PBS at 2.5 mg/mL as a clear solution, and is also a clear solution in 2% DMSO/ corn oil at 2.5 mg/mL. This compound in 2% DMSO/0.5% Tween 80/PBS is a homogeneous suspension at 2.5 mg/mL at first. After stay for a while, the precipitation goes out at the bottom of the tube.
