Synthesis of novel 1H-Pyrazolo[3,4-b]pyridine derivatives as DYRK 1A/1B inhibitors

As DYRK1A and 1B inhibitors, 1H-pyrazolo[3,4-b]pyridine derivatives were synthesized. Mostly, 3-aryl-5-arylamino compounds (6) and 3,5-diaryl compounds (8 and 9) were prepared and especially, 3,5-diaryl compound 8 and 9 showed excellent DYRK1B inhibitory enzymatic activities with IC50 Values of 3–287 nM. Among them, 3-(4-hydroxyphenyl), 5-(3,4-dihydroxyphenyl)-1H-pyrazolo[3,4-b]pyridine (8h) exhibited the highest inhibitory enzymatic activity (IC50 = 3 nM) and cell proliferation inhibitory activity (IC50 = 1.6 μM) towards HCT116 colon cancer cells. Also compound 8h has excellent inhibitory activities in patient-derived colon cancer organoids model as well as in 3D spheroid assay model of SW480 and SW620. The docking study supported that we confirmed that compound 8h binds to DYRK1B through various hydrogen bonding interactions and hydrophobic interactions.

Discovery of a Novel Series of 7-Azaindole Scaffold Derivatives as PI3K Inhibitors with Potent Activity

The phosphoinositide 3-kinase (PI3K) inhibitors potently inhibit the signaling pathway of PI3K/AKT/mTOR, which provides a promising new approach for the molecularly targeted cancer therapy. In this work, a novel series of 7-azaindole scaffold derivatives was discovered by the fragment-based growing strategy. The structure-activity relationship profiles identified that the 7-azaindole scaffold derivatives exhibit potent activity against PI3K at molecular and cellular levels as well as cell proliferation in a panel of human tumor cells.

Identification of GZD824 as an orally bioavailable inhibitor that targets phosphorylated and nonphosphorylated breakpoint cluster region-Abelson (Bcr-Abl) kinase and overcomes clinically acquired mutation-induced resistance against imatinib

Bcr-AblT315I mutation-induced imatinib resistance remains a major challenge for clinical management of chronic myelogenous leukemia (CML). Herein, we report GZD824 (10a) as a novel orally bioavailable inhibitor against a broad spectrum of Bcr-Abl mutants including T315I. It tightly bound to Bcr-AblWT and Bcr-AblT315I with Kd values of 0.32 and 0.71 nM, respectively, and strongly inhibited the kinase functions with nanomolar IC50 values. The compound potently suppressed proliferation of Bcr-Abl-positive K562 and Ku812 human CML cells with IC 50 values of 0.2 and 0.13 nM, respectively. It also displayed good oral bioavailability (48.7%), a reasonable half-life (10.6 h), and promising in vivo antitumor efficacy. It induced tumor regression in mouse xenograft tumor models driven by Bcr-AblWT or the mutants and significantly improved the survival of mice bearing an allograft leukemia model with Ba/F3 cells harboring Bcr-AblT315I. GZD824 represents a promising lead candidate for development of Bcr-Abl inhibitors to overcome acquired imatinib resistance.
