GNE-049 (GNE049) 是一种有效的、选择性的、口服的 CBP/p300 bromodomain 抑制剂，生化 IC50 分别为 1.1/2.3 nM。

GNE-049 (GNE049) is a potent, selective, orally available inhibitor of CBP/p300 bromodomain with biochemical IC50 of 1.1/2.3 nM, respectively; displays 3,850-fold selectivity over BRD4; shows excellent potency (12 nM) in a BRET cellular assay and inhibits the expression of MYC with EC50 of 14 nM in MV-4-11 cells; demonstrates significant dose-dependent inhibition of AR signaling and PC proliferation in vitro and in vivo.

GNE-049 is selected for further profiling as it has the best balance ofliver microsomes (LM) stability, selectivity, and cellular potency GNE-049 has excellent potency in the BRET cellular assay and, in an orthogonal measure of the target engagement, GNE-049 is shown to inhibit the expression of MYC (MV4-11 cell line) with an EC50 of 14 nM.

GNE-049 demonstrates acceptable PK in mouse, rat, dog, and monkey. Determination of potency versus a selection of bromodomains revealed that GNE-049 is selective for CBP/P300 and, importantly, quite selective (3820-fold) over BRD4(1). GNE-049 is further evaluated in a rat single dose (30-250 mg/kg QD) toxicokinetic study. Adverse central nervous system (CNS)-related signs (e.g., marked hyperactivity and vocalization) are observed in several of the rats at the 250 mg/kg dose level. Furthermore, at the 250 mg/kg dose level, the ratio of the unbound drug concentration in brain to unbound drug concentration in plasma (Kp,uu) 3 h post dose is determined to be 0.43, indicating that GNE-049 is penetrating into the CNS and potentially resulting in the observed toxicity.
