Rong, Deqin;Zhou, Kaixin;Fang, Wei;Yang, Hong;Zhang, Yi;Shi, Qiongyu;Huang, Yuting;Li, Jiayi;Dong, Hui;Li, Lanlan;Ding, Jian;Huang, Xun;Wang, Yuanxiang research published 《 Structure-Aided Design, Synthesis, and Biological Evaluation of Potent and Selective Non-Nucleoside Inhibitors Targeting Protein Arginine Methyltransferase 5》, the research content is summarized as follows. PRMT5 is a major type II protein arginine methyltransferase and plays important roles in diverse cellular processes. Overexpression of PRMT5 is implicated in various types of cancer. Many efforts have been made to develop potent and selective PRMT5 inhibitors, the most potent of which is usually derived from nucleoside structures. Here, we designed a novel series of non-nucleoside PRMT5 inhibitors through the structure-aided drug design approach. SAR exploration and metabolic stability optimization led to the discovery of compound 41 as a potent PRMT5 inhibitor with good selectivity. Addnl., compound 41 exerted antiproliferative effects against A375 cells by inducing apoptosis and potently inhibited the methyltransferase activity of PRMT5 in cells. Moreover, it showed attractive pharmacokinetic properties and markedly suppressed the tumor growth in an A375 tumor xenograft model. These results clearly indicate that 41 is a highly potent and selective non-nucleoside PRMT5 inhibitor.

An novel high affinity multi-target directed ligands (MTDLs) against AChE and NMDAR, with reduced hepatotoxicity, performed in-silico structure-based modifications on tacrine, chem. synthesis of the derivatives and in-vitro validation of their activities. Nineteen such derivatives I [R = H, methylcarbamoyl, hydrazinecarbonyl, ethoxycarbonyl; R¹ = 2-furanyl, 1-methylpyrazol-4-yl, 2-FC₆H₄, etc.] showed inhibition with IC₅₀ values in the range of 18.53 ± 2.09 – 184.09 ± 19.23 nM against AChE and 0.27 ± 0.05 – 38.84 ± 9.64μM against NMDAR. Some of the selected compounds protected rat primary cortical neurons from glutamate induced excitotoxicity. Two of the tacrine derived MTDLs, I [R = H, R¹ = 1-methylpyrazol-4-yl; R = H, R¹ = 2-FC₆H₄] exhibited in-vivo efficacy in rats by protecting against behavioral impairment induced by administration of the excitotoxic agent, monosodium glutamate.

Signaling via the receptor tyrosine kinase CSF1R is thought to play an important role in recruitment and differentiation of tumor-associated macrophages (TAMs). TAMs play pro-tumorigenic roles, including the suppression of anti-tumor immune response, promotion of angiogenesis and tumor cell metastasis. Because of the role of this signaling pathway in the tumor microenvironment, several small mol. CSF1R kinase inhibitors are undergoing clin. evaluation for cancer therapy, either as a single agent or in combination with other cancer therapies, including immune checkpoint inhibitors. Herein the authors describe the authors’ lead optimization effort that resulted in the identification of a potent, cellular active and orally bioavailable bis-amide CSF1R inhibitor. Docking and biochem. anal. allowed the removal of a metabolically labile and poorly permeable Me piperazine group from an early lead compound Optimization led to improved metabolic stability and Caco2 permeability, which in turn resulted in good oral bioavailability in mice.

Dual-specificity tyrosine-(Y)-phosphorylation regulated kinase 1A (DYRK1A) is a therapeutic target of interest due to the roles it plays in both neurol. diseases and cancer. We present the development of the first macrocyclic inhibitors of DYRK1A. Initial lead inhibitor JH-XIV-68-3 (3) displayed selectivity for DYRK1A and close family member DYRK1B in biochem. and cellular assays, and demonstrated antitumor efficacy in head and neck squamous cell carcinoma (HNSCC) cell lines. However, we noted that it suffered from rapid aldehyde oxidase (AO)-mediated metabolism To overcome this liability, we generated a derivative (JH-XVII-10 (10)), where fluorine was introduced to block the 2-position of the azaindole and render the mol. resistant to AO activity. We showed that 10 maintains remarkable potency and selectivity in biochem. and cellular assays as well as antitumor efficacy in HNSCC cell lines and improved metabolic stability. Therefore, 10 represents a promising new scaffold for developing DYRK1A-targeting chem. probes and therapeutics.
