CAS No. : 2079885-05-3
MCE 国际站:L-Moses
产品活性:L-Moses (L-45) 是第一个有效的选择性 p300/CBP 相关因子 (PCAF) 溴结构域 (Brd) 抑制剂,Kd 为 126 nM。
研究领域:Epigenetics
作用靶点:Epigenetic Reader Domain
In Vitro: L-Moses (L-45) disrupts PCAF-Brd histone H3.3 interaction in cells using a nanoBRET assay, and a co-crystal structure of L-Moses with the homologous Brd PfGCN5 from Plasmodium falciparum rationalizes the high selectivity for PCAF and GCN5 bromodomains. A structure using highly homologous (64 % identity) Brd from Plasmodium falciparum, PfGCN5, of which L-Moses is also a potent ligand (isothermal titration calorimetry (ITC) KD 280 nM), is successfully obtained (PDB: 5TPX). L-Moses binds in the acetylated lysines (KAc) -binding pocket of PfGCN (blue ribbon and sticks) and makes H-bonds (dotted lines) through the triazole to N1436 and the first of a network of four water molecules (red spheres).
In Vivo: L-Moses (L-45) shows no observable cytotoxicity in peripheral blood mononuclear cells (PBMC), good cell-permeability, and metabolic stability in human and mouse liver microsomes, supporting its potential for in vivo use.
