Synthesis of 2-oxoquinoline derivatives as dual pim and mTORC protein kinase inhibitors
Giri R. Gnawali ; Koichi Okumura ; Karolina Perez , et al. Med. Chem. Res.,2022,31(7):1154-1175. DOI: 10.1007/s00044-022-02904-z PubMed ID: 36389181

Abstract: Compound VBT-5445 was identified as an inhibitor to block the association of Pim and the protein Enhancer of Decapping 3 (EDC3), a Pim substrate, which normally functions to enhance the decapping of messenger RNA (mRNA). It was also shown to inhibit both the Pim and mTORC protein kinases. The activity of this compound class can be fine-tuned by structural modification. A series of VBT analogs were designed, synthesized, and evaluated. These compounds decrease the growth of multiple cancer types, including pancreas, prostate, breast, lung, and leukemia. Notably, 6-methyl (GRG-1-31, 6d), 4-chloro (GRG-1-34, 6e), 4-Bromo (GRG-1-35, 6f), and phenylthio substituted (GRG-1-104, 6n) derivatives are highly potent at inhibiting tumor growth. The ability of these compounds to block cancer growth in vitro is highly correlated with their activity as mTORC inhibitors. The toxicity of GRG 1–34 is low in mice treated with twice-daily gavage for 30 days and did not induce weight loss. Pharmacokinetics of a single oral dose demonstrated a peak concentration at 0.5?h after gavage. In summary, further development of this compound class has the potential to inhibit important signaling pathways and impact cancer treatment.

97%; 0.05% | With hydrogen; acetic acid;nickel; at 40 - 45℃; under 13501.4 Torr; for 4h; | Example of the preparation of 2-aminomethyl-3-chloro-5-trifluoromethylpyridine 400g of acetic acid and 6g of Ni-Ra (previously washed with water until washings were at a pH of 7) were loaded in a 1L stainless steel reactor. The reactor was purged with nitrogen and then hydrogen. Heating was applied to the reactor to raise the temperature up to 40C and the reactor pressure was raised to 18 bar with hydrogen. 120g of 3-chloro-2-cyano-5-trifluoromethylpyridine (0.571 mol) were added by pump over 2 hours. The reaction was exothermic and temperature raised to 45C. Hydrogen consumption was monitored. After 2 hours, no more hydrogen was consumed and the reaction was complete. The mixture was cooled down to 20C and then vented off and purged with nitrogen. The catalyst was filtered. The solution of 2-aminomethyl-3-chloro-5-trifluoromethylpyridine acetic acid salt was assayed by liquid chromatography. 0.558 moles of 2-aminomethyl-3-chloro-5-trifluoromethylpyridine was formed and a 97% yield of 2-aminomethyl-3-chloro-5-trifluoromethylpyridine over 3-chloro-2-cyano-5-trifluoromethylpyridine was obtained. A yield of only 0.05% yield of the dechlorinated analogue was obtained. |
