Ma, Junlong; Chen, Heng; Yang, Jie; Yu, Zutao; Huang, Pan; Yang, Haofeng; Zheng, Bifeng; Liu, Rangru; Li, Qianbin; Hu, Gaoyun; Chen, Zhuo published the artcile< Binding pocket-based design, synthesis and biological evaluation of novel selective BRD4-BD1 inhibitors>, Safety of 3-(3-Chlorophenyl)-3-oxopropanenitrile, the main research area is neoplasm antitumor BRD4 BD1; BD1 inhibitor; BRD4; Cancer; Computer-aided drug design; Fibrosis; Structure-activity relationship.

Bromodomain-containing protein 4 (BRD4), consisting of two tandem bromodomains (BD1 and BD2), is key epigenetic regulator in fibrosis and cancer, which has been reported that BD1 and BD2 have distinct roles in post-translational modification. But there are few selective inhibitors toward those two domains. Herein, this study designed and synthesized a series of novel selective BRD4-BD1 inhibitors, using computer-aided drug design (CADD) approach focused on exploring the difference of the binding pockets of BD1 and BD2, and finding the His437 a crucial way to achieve BRD4-BD1 selectivity. Our results revealed that the compound 3u(I) is a potent selective BRD4-BD1 inhibitor with IC50 values of 0.56 μM for BD1 but >100 μM for BD2. I exhibited a broad spectrum of anti-proliferative activity against several human cancer and fibroblastic cell lines, which might be related to its capability of reducing the expression of c-Myc and collagen I. Furthermore, I could induce apoptosis in A375 cells. To the contrary, the selective BD2 inhibitor, RVX-208, did not indicate any of these activities. Our findings highlight that the function of BRD4-BD1 might be predominant in fibrosis and cancer. And it is rational to further develop novel selective BRD4-BD1 inhibitors.

Herein, document of a large collection of 108 2-amino-4,6-disubstituted-pyrimidine derivatives as potent, structurally simple, and highly selective A1AR ligands. The most attractive ligands were confirmed as antagonists of the canonical cyclic adenosine monophosphate pathway, and some pharmacokinetic parameters were preliminarilly evaluated. The library, built through a reliable and efficient three-component reaction, comprehensively explored the chem. space allowing the identification of the most prominent features of the structure-activity and structure-selectivity relationships around this scaffold. These included the influence on the selectivity profile of the aromatic residues at positions R4 and R6 of the pyrimidine core but most importantly the prominent role to the unprecedented A1AR selectivity profile exerted by the Me group introduced at the exocyclic amino group. The structure-activity relationship trends on both A1 and A2AARs were conveniently interpreted with rigorous free energy perturbation simulations, which started from the receptor-driven docking model that guided the design of these series.

A series of novel imidazoline derivatives was synthesized and evaluated as neuropeptide Y (NPY) Y5 receptor antagonists. Optimization of previously reported imidazoline leads, I and II, was attempted by introduction of substituents at the 5-position on the imidazoline ring and modification of the bis(4-fluorophenyl) moiety. A number of potent derivatives without human ether-a-go-go related gene potassium channel (hERG) activity were identified. Selected compounds, including III, were shown to have excellent brain and CSF permeability. Compound III displayed a suitable pharmacokinetic profile for chronic in vivo studies and potently inhibited D-Trp34NPY-induced acute food intake in rats. Oral administration of III resulted in a potent reduction of body weight in a diet-induced obese mouse model.
