Synthesis and antileishmanial evaluation of thiazole orange analogs

Cyanine compounds have previously shown excellent in vitro and promising in vivo antileishmanial efficacy, but the potential toxicity of these agents is a concern. A series of 22 analogs of thiazole orange ((Z)-1-methyl-4-((3-methylbenzo[d]thiazol-2(3H)-ylidene)methyl)quinolin-1-ium salt), a commercial cyanine dye with antileishmanial activity, were synthesized in an effort to increase the selectivity of such compounds while maintaining efficacy. Cyanines possessing substitutions on the quinolinium ring system displayed potency against Leishmania donovani axenic amastigotes that differed little from the parent compound (IC50 12–42 nM), while ring disjunction analogs were both less potent and less toxic. Changes in DNA melting temperature were modest when synthetic oligonucleotides were incubated with selected analogs (ΔTm ≤ 5 °C), with ring disjunction analogs showing the least effect on this parameter. Despite the high antileishmanial potency of the target compounds, their toxicity and relatively flat SAR suggests that further information regarding the target(s) of these molecules is needed to aid their development as antileishmanials.

Direct access of the chiral quinolinyl core of cinchona alkaloids via a br?nsted acid and chiral amine co-catalyzed chemo- and enantioselective α-alkylation of quinolinylmethanols with enals

A strategy for the facile construction of the chiral quinolinylmethanolic structure, a core featured in cinchona alkaloids, is reported. A new reactivity is harnessed by TfOH-promoted chemoselective activation of α-C-H over O-H bond in quinolinylmethanols. The new reactivity is successfully engineered with an iminium catalysis in a synergistic manner to create a powerful conjugate addition-cyclization cascade process for synthesis of chiral quinoline derived π-butyrolactones in good yields and with good to excellent enantioselectivities. The method enables the first total synthesis of natural product broussonetine in three steps.

5-Amino-2-Aroylquinolines as highly potent tubulin polymerization inhibitors

A series of aroylquinoline derivatives were synthesized and evaluated for anticancer activity. 5-Amino6-methoxy-2-aroylquinoline 15 showed more potent antiproliferative activity (IC50 values ranging from 0.2 to 0.4 nM) as compared to la (combretastatin A-4) (IC50 = 1-9-835 nM) against various human cancer cell lines and a MDR-resistant cancer cell line. Compound 15 (IC50 = 1-6 μM) exhibited more potent inhibition of tubulin polymerization than la (IC50 = 2.1 μM) and showed strong binding property to the colchicine binding site of microtubules.

New nonsymmetric phenanthrolines as very effective ligands in the palladium-catalyzed carbonylation of nitrobenzene

Inspired by the results of a previous mechanistic study, a series of mostly new nonsymmetric phenanthrolines were synthesized and tested as ligands in the palladium-catalyzed reductive carbonylation reaction of nitrobenzene to methyl phenylcarbamate. Very good results were obtained when the asymmetry was of an electronic nature (a donating substituent in the para position of one of the two pyridinic rings and an electron-withdrawing or no substituent on the para position of the other pyridinic ring), but steric hindrance in the ortho or meta position retarded the reaction. The TOF for the modified system is the highest ever reported for any carbonylation reaction of nitroarenes.

AN IMPROVED PROCESS FOR THE SYNTHESIS OF QUINOLINE DERIVATIVES

The present invention provides an improved process for the synthesis of quinoline derivatives.
