4-Chlorobenzenamine and 3-Hydroxy-2-naphthoic acid condensation.

Общее описание

A cell-permeable naphthamide compound that effectively blocks the interaction between the KIX domain of CBP and the KID domain of CREB in HEK293T-based and cell-free Renilla luciferase (RLuc) complementation assays (IC₅₀ = 2.26 and 2.9 M, respectively) by directly binding to CBP′s KIX domain (K_d ~8.6 M using a recombinant KIX). Shown to inhibit CRE- (cAMP response element) dependent transcription activity induced by forskolin in a HEK293T-based RLuc reporter assay (IC₅₀<2.5 M), while exhibiting little effect against the KID-independent CREB-VP16 transcription activity. Also reported to inhibit the enzymatic activity of Firefly luciferase (IC₅₀ ~1 M), but not that of RLuc.
