Yu, Ru-Nan;Chen, Cheng-Juan;Shu, Lei;Yin, Yuan;Wang, Zhi-Jian;Zhang, Tian-Tai;Zhang, Da-Yong research published 《 Structure-based design and synthesis of pyrimidine-4,6-diamine derivatives as Janus kinase 3 inhibitors》, the research content is summarized as follows. 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 I, 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, I showed moderate potency inhibiting IL-2-stimulated T cell proliferation. The data supports the further development of novel JAKs inhibitors.
