In this study, we described a series of N-(pyrimidin-2-yl)-1,2,3,4-tetrahydroisoquinolin-6-amine derivatives as selective JAK2 (Janus kinase 2) inhibitors. Systematic exploration of the structure-activity relationship though cyclization modification based on previously reported compound 18e led to the discovery of the superior derivative 13ac. Compound 13ac showed excellent potency on JAK2 kinase, SET-2, and Ba/F3V617F cells (high expression of JAK2V617F mutation) with IC50 values of 3, 11.7, and 41 nM, respectively. Further mechanistic studies demonstrated that compound 13ac could downregulate the phosphorylation of downstream proteins of JAK2 kinase in cells. Compound 13ac also showed good selectivity in kinase scanning and potent in vivo antitumor efficacy with 82.3% tumor growth inhibition in the SET-2 xenograft model. Moreover, 13ac significantly ameliorated the disease symptoms in a Ba/F3-JAK2V617F allograft model, with 77.1% normalization of spleen weight, which was more potent than Ruxolitinib.
A Continuous Flow Strategy for the Facile Synthesis and Elaboration of Semi-Saturated Heterobicyclic Fragments

An efficient hydrogenation protocol under continuous flow conditions was developed for the synthesis of underrepresented semi-saturated bicyclic fragments containing highly sp3-rich skeletons for fragment-based drug discovery (FBDD) programs. Excellent yields were generally achieved by using Pd/C (10 % w/w) and RaNi at 25–150 °C under 4–100 bar of hydrogen pressure. The generated fragments, with appropriate physicochemical properties, present diverse hydrogen-bonding pharmacophores and useful vectors for their synthetic elaboration in the optimization stage. Successive, simple functionalizations in continuous flow were accomplished to demonstrate the opportunity to develop multi-step continuous flow synthesis of valuable starting points for FBDD campaigns. A conclusive quality control (QC) was essential to discard those structures which do not fit the typical fragment library parameters.
