Autophagy inducers represent new promising agents for the treatment of a wide range of medical illnesses. However, safe autophagy inducers for clinical applications are lacking. Inhibition of cdc2-like kinase 1 (CLK1) was recently found to efficiently induce autophagy. Unfortunately, most of the known CLK1 inhibitors have unsatisfactory selectivity. Herein, we report the discovery of a series of new CLK1 inhibitors containing the 1H-[1,2,3]triazolo[4,5-c]quinoline scaffold. Among them, compound 25 was the most potent and selective, with an IC50 value of 2 nM against CLK1. The crystal structure of CLK1 complexed with compound 25 was solved, and the potency and kinase selectivity of compound 25 were interpreted. Compound 25 was able to induce autophagy in in vitro assays and displayed significant hepatoprotective effects in the acetaminophen (APAP)-induced liver injury mouse model. Collectively, due to its potency and selectivity, compound 25 could be used as a chemical probe or agent in future mechanism-of-action or autophagy-related disease therapy studies.

Herein, we reported the preparation and in vitro development of a novel series of quinoline-based mTOR inhibitors, some of which were obtained via introducing a ring-opening strategy. As for enzymatic activity, more than half of these quinoline derivatives exhibited moderate to potent inhibition against mTOR. Among them, six compounds showed IC50 values below 50 nM. In particular, several quinolines exhibited remarkably enhanced anti-proliferative activities against all the three tested tumor cell lines in contrast to the initial lead 9. As a representative in this series, compound 24 demonstrated IC50 values of 0.11, 0.17 and 0.04 μM against HCT-116, PC-3 and MCF-7 cell lines, respectively. Besides, compounds 17 and 24 were identified to be selective over class I PI3Ks. Further Western blot analysis validated the dual inhibition of mTORC1 and mTORC2 as a result of compound 24 treatment in the MCF-7 cell line, which was beneficial for conquering the S6K/IRS1/PI3K negative feedback loop. Moreover, acceptable stability was displayed by compound 17, another representative of this series, in simulated intestinal fluid (SIF), simulated gastric fluid (SGF), as well as rat liver microsome (RLM). By virtue of the favorable biological profiles, several quinolines merit further in vivo investigation.
