- Design and synthesis of new 2-anilinoquinolines bearing N-methylpicolinamide moiety as potential antiproliferative agents
-
A series of new 2-anilinoquinolines 6a–o possessing the substantial N-methylpicolinamide motif at C5 has been designed and synthesized as sorafenib analogs. The antiproliferative activities of the target compounds were preliminarily appraised against a panel of three human cancer cell lines (MCF-7, SK-BR3, and HCT116), and a selected array was further tested over a panel of approximately 60 cancer cell lines at NCI at 10?μM concentration. Interestingly, compounds 6c, 6d, 6j, 6k, and 6l showed promising selective anticancer activities (growth inhibition >80%) toward certain cancer cells at 10?μM testing dose. Compounds 6d and 6j were advanced to five-dose testing mode to determine their GI50 values and compared with our previously reported ureidoquinoline B and sorafenib as reference compounds. The 4-chloro-3-trifluoromethylaniline derivative 6j manifested superior potency than both compound B and sorafenib over eleven and eight cell lines, respectively. It showed GI50 values of 0.36, 0.66, 0.68, and 0.60?μM against the breast MDA-MB-468, renal A498, and melanoma SK-MEL-5 and UACC-62 cell lines, respectively. Moreover, both 6d and 6j exerted low cytotoxic effects against HFF-1 normal cell line. Furthermore, compounds 6d and 6j were tested against both B-RafV600E and C-Raf kinases and displayed modest inhibitory activities, which were justified by molecular docking study. Compound 6j could serve as a promising candidate for further development of potent anticancer chemotherapeutics.

- Novel 5-substituted-2-anilinoquinolines with 3-(morpholino or 4-methylpiperazin-1-yl)propoxy moiety as broad spectrum antiproliferative agents: Synthesis, cell based assays and kinase screening
-
A series of new 2-anilinoquinolines possessing 3-(morpholino or 4-methylpiperazin-1-yl)propoxy moiety at C5 of quinoline has been designed and synthesized as potential anticancer agents. Their antiproliferative activities were evaluated against a panel of 60 cancer cell lines at NCI and compared with gefitinib as a reference compound. Most of the tested compounds displayed potent and broad spectrum antiproliferative activities. Compounds 7d, 7f and 7g showed strong inhibitory and lethal effects at 10?μM concentration. Moreover, they manifested superior potencies and efficacies than gefitinib across the most tested cell lines. Compound 7d, with 4-chloro-3-trifluoromethylphenyl group, proved to be the most potent and efficacious derivative in this series, with mean GI50and TGI values of 1.62?μM and 3.47?μM, respectively. Kinase screening of 7d against a panel of 47 oncogenic kinases revealed its selective inhibitory effect (96% inhibition) towards TrkA kinase. Furthermore, the most potent compounds showed low cytotoxic effects against HFF-1 normal cell line.

- Synthesis and in vivo evaluation of 5-methoxy-2-(phenylethynyl)quinoline (MPEQ) and [11C]MPEQ targeting metabotropic glutamate receptor 5 (mGluR5)
-
The synthesis and in vivo evaluation of 5-methoxy-2-(phenylethynyl) quinoline (MPEQ) 3 as a potential mGluR5 selective radioligand is described. We have identified MPEQ 3 exhibiting the analgesic effect in the neuropathic pain animal model. The effect of mGluR5 on neuronal activity in rat brain was evaluated through FDG/PET imaging in the presence of MPEQ 3. In addition, the PET study of [11C]MPEQ 3 proved that accumulation of [ 11C]MPEQ 3 in rat brain was correlated to the localization of the mGluR5.

- Synthesis and biological evaluation of 2-(arylethynyl)quinoline derivatives as mGluR5 antagonists for the treatment of neuropathic pain
-
We described here the synthesis and biological evaluation of mGluR5 antagonists containing a quinoline ring structure. Using intracellular calcium mobilization assay (FDSS assay), we identified compound 5n, showing high inhibitory activity against mGluR5. In addition, it was found that compound 5n has excellent stability profile. Finally, this compound exhibited favorable analgesic effects in spinal nerve ligation model of neuropathic pain, which is comparable to gabapentin.
