$165
MW: 445.4 Da
CAS Registry #: 328968-36-1
Formula: C24H19N3O6
Target: p300
Background:
C646 binds to p300 as the Z-isomer forming hydrogen bonds between Thr1411, tYR1467, Trp1466 and Arg1410 on the side chains of p300 and oxygen atoms of C646. C646 is also capable of inhibiting a variety of p300 HAT mutants, including T1411A, Y1467F, W1466F and R1410A with IC50 values of 3.4 µM, 7 µM, 5 µM and 2.5 µM respectively.
Description:
C646, a pyrazolone-containing small molecule, is a cell-permeable histone acetyltransferase (HAT) inhibitor that competitively and selectively inhibits the HAT activity of p300, a transcriptional co-activator involved in a variety of gene regulatory pathways and protein acetylation events, with the Ki value of 400 nM and an IC50 value of 1.6 µM .
