Novel 1H-pyrazolo[3,4-d]pyrimidin-6-amino derivatives as potent selective Janus kinase 3 (JAK3) inhibitors. Evaluation of their improved effect for the treatment of rheumatoid arthritis

Selective JAK3 inhibitors have been shown to have a potential benefit in the treatment of autoimmune disorders. Here we report the identification of a series of pyrazolopyrimidine derivatives as potent JAK3 inhibitors that exploit a unique cysteine (Cys909) residue in JAK3. Most of these compounds (13k, 13n and 13 t), displayed stronger anti-JAK3 kinase activity and selectivity than tofacitinib. Furthermore, the most active inhibitor 13t (IC50 = 0.1 nM), also exhibited favourable selectivity for JAK3 in a panel of 9 kinases which contain the same cysteine. In a series of cytokinestimulated cellular analysis, compound 13 t, could potently block the JAK3-STAT signaling pathway. Further biological studies, including cellular antiproliferative activity assays and a rat adjuvant-induced arthritis model for in vivo evaluation, also indicated its efficacy and low toxicity in the treatment of rheumatoid arthritis. The results of these experimental explorations suggested that 13t is a promising lead compound for the development of selective JAK3 inhibitor with therapeutic potential in rheumatoid arthritis.

Preparation method and application of novel 6-amino-1H-pyrazolo[3,4-d]pyrimidine JAK kinase inhibitors

The present invention provides drugs used for preventing, treating and/or ameliorating autoimmune diseases (such as psoriasis, rheumatoid arthritis, inflammatory enteritis diseases, Sjogren's syndrome, Behcet's disease, multiple sclerosis and systemic lupus erythematosus). The drugs have excellent JAK kinase inhibitory activity. The present invention also provides pharmaceutically acceptable compositions including the above compounds, and methods for preparing the compounds.

Design, synthesis and biological evaluation of novel 7H-pyrrolo[2,3-d]pyrimidine derivatives as potential FAK inhibitors and anticancer agents

A series of 7H-pyrrolo[2,3-d]pyrimidine derivatives possessing a dimethylphosphine oxide moiety were designed, synthesized and evaluated as novel Focal adhesion kinase (FAK) inhibitors. Most compounds potently suppressed the enzymatic activities of FAK, with IC50 values in the 10?8–10?9 M range, and potently inhibited the proliferation of breast (MDA-MB-231) and lung (A549) cancer cell lines. The representative compound 25b exhibited potent enzyme inhibition (IC50 = 5.4 nM) and good selectivity when tested on a panel of 26 kinases. 25b exhibited antiproliferative activity against A549 cells (IC50 = 3.2 μM) and relatively less cytotoxicity to a normal human cell line HK2. Compound 25b also induced apoptosis and suppressed the migration of A549 cells in a concentration-dependent manner. Further profiling of compound 25b revealed it had good metabolic stability in mouse, rat and human liver microsomes in vitro and showed weak inhibitory activity against various subtypes of human cytochrome P450. The docking study of compound 25b was performed to elucidate its possible binding modes and to provide a structural basis for further structure-guided design of FAK inhibitors.

Structure-based design and synthesis of pyrimidine-4,6-diamine derivatives as Janus kinase 3 inhibitors

Janus kinases (JAKs) play a key role in the proliferation, apoptosis and differentiation of immune cells, and JAKs are considered as an attractive target for the treatment of inflammatory and autoimmune diseases. Here we show the design and optimization of pyrimidine-4,6-diamine derivatives as selectivity JAK3 inhibitors. Compound 11e, which might interact with unique cysteine (Cys909) residue in JAK3, exhibited excellent JAK3 inhibitory activity (IC50 = 2.1 nM) and high JAK kinase selectivity. In cellular assay, 11e showed moderate potency inhibiting IL-2-stimulated T cell proliferation. The data supports the further development of novel JAKs inhibitors.
