A series of new quinoline derivatives was designed, synthesized and evaluated for their antiproliferative activity. The results demonstrated that compounds 11p, 11s, 11v, 11x and 11y exhibited potent antiproliferative activity with IC50 value of lower than 10 μM against seven human tumor cell lines, and N-(3-methoxyphenyl)-7- (3-phenylpropoxy)quinolin-4-amine 11x was found to be the most potent antiproliferative agent against HCT-116, RKO, A2780 and Hela cell lines with an IC50 value of 2.56, 3.67, 3.46 and 2.71 μM, respectively. The antitumor efficacy of the representative compound 11x in mice was also evaluated, and the results showed that compound 11x effectively inhibited tumor growth and decreased tumor weight in animal models. Further investigation on mechanism of action indicated that compound 11x could inhibit colorectal cancer growth through ATG5-depenent autophagy pathway. Therefore, these quinoline derivatives are a new class of molecules that have the potential to be developed as new antitumor drugs.

Co(III)-Catalyzed Enaminone-Directed C-H Amidation for Quinolone Synthesis
Shi, Pengfei,Wang, Lili,Chen, Kehao,Wang, Jie,Zhu, Jin
, p. 2418 - 2421 (2017/05/12)
We report herein the development of a Co(III)-catalyzed enaminone-directed C-H amidation method for synthetic access to quinolones, an important heterocyclic scaffold for diverse pharmaceutically active structures. The C-H coupling with dioxazolones and subsequent deacylation of an installed amide group allow consecutive C-N coupling generation of quinolones with wide-ranging compatible substituent patterns.

Tropical protozoal infections are a significant cause of morbidity and mortality worldwide; four in particular (human African trypanosomiasis (HAT), Chagas disease, cutaneous leishmaniasis, and malaria) have an estimated combined burden of over 87 million disability-adjusted life years. New drugs are needed for each of these diseases. Building on the previous identification of NEU-617 (1) as a potent and nontoxic inhibitor of proliferation for the HAT pathogen (Trypanosoma brucei), we have now tested this class of analogs against other protozoal species: T. cruzi (Chagas disease), Leishmania major (cutaneous leishmaniasis), and Plasmodium falciparum (malaria). Based on hits identified in this screening campaign, we describe the preparation of several replacements for the quinazoline scaffold and report these inhibitors' biological activities against these parasites. In doing this, we have identified several potent proliferation inhibitors for each pathogen, such as 4-((3-chloro-4-((3-fluorobenzyl)oxy)phenyl)amino)-6-(4-((4-methyl-1,4-diazepan-1-yl)sulfonyl)phenyl)quinoline-3-carbonitrile (NEU-924, 83) for T. cruzi and N-(3-chloro-4-((3-fluorobenzyl)oxy)phenyl)-7-(4-((4-methyl-1,4-diazepan-1-yl)sulfonyl)phenyl)cinnolin-4-amine (NEU-1017, 68) for L. major and P. falciparum.

We previously reported that substituted 4-aminoquinolines with a phenyl ether substituent at the 7-position of the quinoline ring and the capability of intramolecular hydrogen bonding between the protonated amine on the side chain and a hydrogen bond acceptor on the amine's alkyl substituents exhibited potent antimalarial activity against the multidrug resistant strain P. falciparum W2. We employed a parallel synthetic method to generate diaryl ether, biaryl, and alkylaryl 4-aminoquinoline analogues in the background of a limited number of side chain variations that had previously afforded potent 4-aminoquinolines. All subsets were evaluated for their antimalarial activity against the chloroquine-sensitive strain 3D7 and the chloroquine-resistant K1 strain as well as for cytotoxicity against mammalian cell lines. While all three arrays showed good antimalarial activity, only the biaryl-containing subset showed consistently good potency against the drug-resistant K1 strain and good selectivity with regard to mammalian cytotoxicity. Overall, our data indicate that the biaryl-containing series contains promising candidates for further study.
