Histone Deacetylase Inhibitor VII, 106 - CAS 937039-45-7 - Calbiochem,N¹-(2-Aminophenyl)-N⁷- p-tolylheptanediamide, Pimelic Diphenylamide 106

一般描述

A cell-permeable p-tolylbenzamide and a Histone Deacetylase (HDAC) Inhibitor IV (Cat. No. 382170) analog that acts as a selective inhibitor against class I HDAC1,2,3 (IC50 = 0.15, 0.76, and 0.37 μM with 15, 30, and 180 min preincubation, respectively), while exhibiting much lower acitivity against class I HDAC8 (IC50 ≥ 5μM with 3 h preincubation) and no activity against class II HDAC4/5/7 even at concentrations as high as 180μM. Although the mode of inhibition is mechanistically competitive and reversible, due to the slow- and tight-binding nature, long preincubation is often required for effective in vitro enzyme inhibition, while 106-induced cellular H3 hyperacetylation is shown to persist for more than 6 hours after inhibitor removal by washing in GM15850 culture. 106 is reported to be less cytotoxic than TSA (Cat. No. 647925), MS-275, and SAHA (EC50 = 6.3, 0.328, 0.768, and 1.5 μM, respectively, in GM15850 killing). A cell-permeable p-tolylbenzamide and a Histone Deacetylase (HDAC) Inhibitor IV (Cat.
