Se ha demostrado que C646, un potente y selectivo inhibidor de la histona acetiltransferasa p300/CBP (Ki 400 nM), tiene actividad pleiotrópica, incluidos los efectos neuroprotectores, anticancerígenos y de transición mesenquimal antiepitelial (anti-EMT) [1-4].
C646(10µM; 2 h) suprime la producción de citoquinas estimuladas por LPS[5]. C646(10-50 µM) inhibe la acetilación de la histona H3 y la proliferación de células cancerosas de páncreas [6]. C646(20 µM; 4 h) activa la señalización de insulina y aumenta la translocación de la membrana de los sustratos de proteínas del receptor de insulina (IRS) en ausencia de insulina en las células Hepa1-6[7].
C646(10 ul; una dosis por día; 7 días) alodinia mecánica atenuada e hiperalgesia térmica, acompañada de una expresión suprimida de COX-2 en la médula espinal[8]. El tratamiento C646(1 µg/gm; i.v;14 días) atenuó la acetilación p300 y H3K56 y mejoró la rigidez arterial y la reserva de flujo coronario (CFR) a través de la mejora de la disfunción de las células endoteliales (EC) y la supresión de NF-κB[9].

Método de preparación | En este ensayo, la producción de Ac-H4-15 marcado con 14C se monitorea electroforóricamente. Las reacciones se realizaron en 20 mM HEPES (pH 7.9), y contuvieron 5 mM DTT, 80 µM EDTA, 40 µg/ml BSA, 100 µM H4-15, y 5 nM p300. DMSO se mantuvo constante al 2.5%, , y los inhibidores (incluyendo C646) se examinaron a 25 µM. Las reacciones se incubaron a 30 C durante 10 minutos, se inició con la adición de una mezcla 1:1 de 12C-acetyl-CoA y 14C-acetyl-CoA a una concentración final de 20 µM, y se permitió ejercutar durante 10 minutos a 30 C. Luego, las reacciones se atenúan con la adición de un R14% de SDS (w/v). La rotación se mantuvo por debajo del 10%. |
