One-pot multicomponent green Hantzsch synthesis of 1,2-dihydropyridine derivatives with antiproliferative activity.

Project description:A rapid route for obtaining unsymmetrical 1,2-dihydropyridines (1,2-DHPs) as opposed to 1,4-dihydropyridines (1,4-DHPs) has been achieved via a one-pot multicomponent Hantzsch reaction. A benign protocol has been developed for the preparation of various 1,2-dihydropyridine derivatives using heterogenized phosphotungstic acid on alumina support (40 wt %). High yields of over 75% have been accomplished in just 2-3.5 h after screening several heterogeneous catalysts and investigating the optimal reaction conditions. The catalyst chosen has passed the heterogeneity test and was shown to have the potential of being reused for up to 8 consecutive cycles before having a significant loss in activity. In addition, aromatic aldehydes gave the aforementioned regioisomer while the classical 1,4-DHPs were obtained when carrying out the reaction using aliphatic aldehydes. The preliminary study of the antiproliferative activity against human solid tumor cells demonstrated that 1,2-DHPs could inhibit cancer cell growth in the low micromolar range.

Imidazo[1,2-a]pyridine derivatives synthesis from lignin β-O-4 segments via a one-pot multicomponent reaction.

Project description:The catalytic conversion of lignin into N-containing chemicals is of great significance for the realization of value-added biorefinery concept. In this article, a one-pot strategy was designed for the transformation of lignin β-O-4 model compounds to imidazo[1,2-a]pyridines in yields up to 95% using 2-aminopyridine as a nitrogen source. This transformation involves highly coupled cleavage of C-O bonds, sp3C-H bond oxidative activation, and intramolecular dehydrative coupling reaction to construction of N-heterobicyclic ring. With this protocol, a wide range of functionalized imidazo[1,2-a]pyridines sharing the same structure skeleton as those commercial drug molecules, such as Zolimidine, Alpidem, Saripidem, etc., were synthesized from different lignin β-O-4 model compounds and one β-O-4 polymer, emphasizing the application feasibility of lignin derivatives in N-heterobicyclic pharmaceutical synthesis.

Efficient One-Pot Synthesis of Novel Caffeic Acid Derivatives as Potential Antimalarials.

Project description:New protocol for the preparation of the novel caffeic acid derivatives using the Wittig reaction has been applied to follow the principles of green chemistry. The compounds have been evaluated against chloroquine-sensitive and chloroquine-resistant P. falciparum strains. Their cytotoxicity to normal human dermal fibroblasts and their propensity to induce hemolysis have been also determined. Ethyl (2E)-3-(2,3,4-trihydroxyphenyl)-2-methylpropenoate has exhibited the highest antiplasmodial activity against P. falciparum strains without the cytotoxic and hemolytic effects. This derivative is significantly more potent than caffeic acid parent structure. The application of our one-step procedure has been shown to be rapid and efficient. It allows for an easy increase of input data to refine the structure-activity relationship model of caffeates as the antimalarials. The one-step approach meets the conditions of "atom economy" and eliminates hazardous materials. Water has been used as the effective medium for the Wittig reaction to avoid toxic organic solvents.

Efficient one-pot synthesis of functionalised imidazo[1,2-a]pyridines and unexpected synthesis of novel tetracyclic derivatives by nucleophilic aromatic substitution.

Project description:Novel tetracyclic imidazo[1,2-a]pyridine derivatives have been prepared by intramolecular nucleophilic aromatic substitution of 5-fluoroimidazo[1,2-a]pyridines under basic conditions. Use of the non-nucleophilic alcoholic solvent tert-butanol, rather than methanol, increased the yield of the tetracycles by reducing the competing intermolecular reaction observed for methanol. In addition, a modified protocol for the dehydration of formamides to isocyanides has been found to be tolerant of an unprotected hydroxyl functional group and one-pot conversion to imidazo[1,2-a]pyridyl-aminocyclohexanol analogues is reported.

Efficient and stable organic solar cells enabled by multicomponent photoactive layer based on one-pot polymerization.

Project description:Degradation of the kinetically trapped bulk heterojunction film morphology in organic solar cells (OSCs) remains a grand challenge for their practical application. Herein, we demonstrate highly thermally stable OSCs using multicomponent photoactive layer synthesized via a facile one-pot polymerization, which show the advantages of low synthetic cost and simplified device fabrication. The OSCs based on multicomponent photoactive layer deliver a high power conversion efficiency of 11.8% and exhibit excellent device stability for over 1000 h (>80% of their initial efficiency retention), realizing a balance between device efficiency and operational lifetime for OSCs. In-depth opto-electrical and morphological properties characterizations revealed that the dominant PM6-b-L15 block polymers with backbone entanglement and the small fraction of PM6 and L15 polymers synergistically contribute to the frozen fine-tuned film morphology and maintain well-balanced charge transport under long-time operation. These findings pave the way towards the development of low-cost and long-term stable OSCs.

Project description:BackgroundThe emergence of drug resistance to the existing antibacterial and anti-HIV-1 therapeutics has posed an urgent medical need to develop new molecules. We describe in this regard, a series of novel N'-arylidene-4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carbohydrazide derivatives with anti-HIV-1 and antibacterial activities were designed and synthesized in this study.MethodsThe synthesized compounds were evaluated for the blocking of both the IN ST process and cell-based HIV-1 replication. The synthesized compounds were also examined for in vitro antibacterial activities using the minimum inhibitory concentration (MIC) assay.ResultsThe results revealed the moderate antibacterial activity of the synthesized compounds. Moreover, no significant integrase inhibitory and anti-HIV-1 activities were observed for the synthesized compounds at concentrations < 100 µM.ConclusionsAccording to the docking analyses, the orientation of the designed scaffold in the active site of integrase is similar to the other inhibitors of the HIV integrase and can be regarded as an acceptable template for further structural modification to improve potencies.

Stereoselective Synthesis of Spirooxindole Derivatives Using One-Pot Multicomponent Cycloaddition Reaction and Evaluation of Their Antiproliferative Efficacy.

Project description:A highly stereoselective, one-pot, multicomponent method has been developed to synthesize pyrrolizidine- and N-methyl pyrrolidine-substituted spirooxindole derivatives. The [3 + 2] cycloaddition reaction involves the reaction between the dipole azomethine ylides, generated in situ from the reaction between isatin and secondary amino acids such as L-proline or sarcosine, and α,β-unsaturated carbonyl compounds as the dipolarophile. The reaction condition was optimized to achieve excellent regio- and stereoselectivity. Products were obtained in good yield using ethanol as a solvent at the reflux temperature. The newly synthesized spirooxindole derivatives were evaluated for their antiproliferative efficacy against National Cancer Institute (NCI)-60 cancer cell lines and DNA G-quadruplex (G4) interaction capacity. Compound 14b produced selective cytotoxicity against leukemia, renal, colon, and prostate cancer cell lines at a 10 μM concentration. The G4 interaction studies further suggested that these spirooxindole derivatives were devoid of any activity as DNA G4 ligands.

2-oxo-1,2-dihydroquinoline 8-monooxygenase: phylogenetic relationship to other multicomponent nonheme iron oxygenases.

Project description:2-Oxo-1,2-dihydroquinoline 8-monooxygenase, an enzyme involved in quinoline degradation by Pseudomonas putida 86, had been identified as a class IB two-component nonheme iron oxygenase based on its biochemical and biophysical properties (B. Rosche, B. Tshisuaka, S. Fetzner, and F. Lingens, J. Biol. Chem. 270:17836-17842, 1995). The genes oxoR and oxoO, encoding the reductase and the oxygenase components of the enzyme, were sequenced and analyzed. oxoR was localized approximately 15 kb downstream of oxoO. Expression of both genes was detected in a recombinant Pseudomonas strain. In the deduced amino acid sequence of the NADH:(acceptor) reductase component (OxoR, 342 amino acids), putative binding sites for a chloroplast-type [2Fe-2S] center, for flavin adenine dinucleotide, and for NAD were identified. The arrangement of these cofactor binding sites is conserved in all known class IB reductases. A dendrogram of reductases confirmed the similarity of OxoR to other class IB reductases. The oxygenase component (OxoO, 446 amino acids) harbors the conserved amino acid motifs proposed to bind the Rieske-type [2Fe-2S] cluster and the mononuclear iron. In contrast to known class IB oxygenase components, which are composed of differing subunits, OxoO is a homomultimer, which is typical for class IA oxygenases. Sequence comparison of oxygenases indeed revealed that OxoO is more related to class IA than to class IB oxygenases. Thus, 2-oxo-1,2-dihydroquinoline 8-monooxygenase consists of a class IB-like reductase and a class IA-like oxygenase. These results support the hypothesis that multicomponent enzymes may be composed of modular elements having different phylogenetic origins.
