Synthesis of 2-alkynylquinolines from 2-chloro and 2,4-dichloroquinoline via Pd/C-catalyzed coupling reaction in water

The Pd/C-CuI-PPh3 catalyst system facilitated Sonogashira coupling of 2-chloroquinoline and 2,4-dichloroquinoline with terminal alkynes in water without generating any significant side products. A variety of 2-alkynylquinolines were prepared from 2-chloroquinoline in good to excellent yields and the 2,4-dichloroquinoline afforded monosubstituted product i.e., 2-alkynyl-4-chloro quinoline with high regioselectivity. The methodology was found to be effective for the alkynylation of 1-chloroisoquinoline and 3-methyl-2-chloroquinoline.

Rad51/BRCA2 disruptors inhibit homologous recombination and synergize with olaparib in pancreatic cancer cells

Olaparib is a PARP inhibitor (PARPi). For patients bearing BRCA1 or BRCA2 mutations, olaparib is approved to treat ovarian cancer and in clinical trials to treat breast and pancreatic cancers. In BRCA2-defective patients, PARPi inhibits DNA single-strand break repair, while BRCA2 mutations hamper double-strand break repair. Recently, we identified a series of triazole derivatives that mimic BRCA2 mutations by disrupting the Rad51-BRCA2 interaction and thus double-strand break repair. Here, we have computationally designed, synthesized, and tested over 40 novel derivatives. Additionally, we designed and conducted novel biological assays to characterize how they disrupt the Rad51-BRCA2 interaction and inhibit double-strand break repair. These compounds synergized with olaparib to target pancreatic cancer cells with functional BRCA2. This supports the idea that small organic molecules can mimic genetic mutations to improve the profile of anticancer drugs for precision medicine. Moreover, this paradigm could be exploited in other genetic pathways to discover innovative anticancer targets and drug candidates.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2682-49-7 is helpful to your research. Application of 2682-49-7

A green approach for organic transformations using microwave reactor

Microwave-assisted organic transformation (MAOR) is presently gaining wide popularity in the field of organic synthesis. The conventional heating technique is gradually being removed from the laboratory and a novel microwave heating technique established to be used in both academia and industry. As compared to the classical organic methodology, the green technology tools have several advantages like dramatically reduced reaction times, improved yields, site selectivity, and the increased product purities with simplification of work-up procedures. In the current study, we have briefly described the overview of recent developments and applications of microwave irradiation in organic transformation with schematic compiling of the organic reactions, bioactive heterocyclic compounds, and so on. This review also presents a critical analysis of the various advantages of microwave irradiation in organic synthesis/transformation compared to the classical or conventional heating. So, we believe that our current study of the green microwave heating technique will be highly beneficial for the researchers from both academia and industry in their near future.

Molecular Docking Studies and Synthesis of Amino-oxy-diarylquinoline Derivatives as Potent Non-nucleoside HIV-1 Reverse Transcriptase Inhibitors

In this study, amino-oxy-diarylquinolines were designed using structure-guided molecular hybridization strategy and fusing of the pharmacophore templates of nevirapine (NVP), efavirenz (EFV), etravirine (ETV, TMC125) and rilpivirine (RPV, TMC278). The anti-HIV-1 reverse transcriptase (RT) activity was evaluated using standard ELISA method, and the cytotoxic activity was performed using MTT and XTT assays. The primary bioassay results indicated that 2-amino-4-oxy-diarylquinolines possess moderate inhibitory properties against HIV-1 RT. Molecular docking results showed that 2-amino-4-oxy-diarylquinolines 8(a-d) interacted with the Lys101 and His235 residue though hydrogen bonding and interacted with Tyr318 residue though pi-pi stacking in HIV-1 RT. Furthermore, 8a and 8d were the most potent anti-HIV agents among the designed and synthesized compounds, and their inhibition rates were 34.0% and 39.7% at 1 muM concentration. Interestingly, 8a was highly cytotoxicity against MOLT-3 (acute lymphoblastic leukemia), with an IC 50 of 4.63¡À0.62 mug/mL, which was similar with that in EFV and TMC278 (IC 50 7.76¡À0.37 and 1.57¡À0.20 mug/ml, respectively). Therefore, these analogs of the synthesized compounds can serve as excellent bases for the development of new anti-HIV-1 agents in the near future.

Synthesis and biological evaluation of 2-aminothiazole-thiazolidinone conjugates as potential antitubercular agents

Aim: Mycobacterium tuberculosis, which causes tuberculosis, continues to infect millions of the global population, resulting in 1.8 million deaths worldwide in 2015. Methodology: Hybrids of 2-amino-4-methylthiazole bearing 5-acetyl/5-ethyl carboxylate functionality with 5-arylidene thiazolidinone moiety (6a-k and 9a-d) were synthesized and screened for antitubercular and antimicrobial activities. Results & discussion: 5-ethyl carboxylate derivative 6k revealed half antitubercular activity (minimal inhibitory concentration = 1.56 mug/ml) than the acetyl analog 6c (minimal inhibitory concentration = 0.78 mug/ml), however, it exhibited more potent broad spectrum antibacterial and antifungal activities in addition to its excellent safety profile with high selectivity toward M. tuberculosis over normal human lung cells. Collectively, these data suggested that compound 6k can be considered as an ideal lead compound for further optimization.

Chronic ethanol ingestion and the risk of acute lung injury: A role for glutathione availability?

Although pulmonary function is not altered, a history of alcohol abuse is an independent outcome variable in the development of acute respiratory distress syndrome. In the absence of cirrhosis, alcohol abuse decreased glutathione, the key antioxidant lining the alveolar space, by 80% and is associated with alveolar banner leak. Neither the glutathione pool nor barrier leak was corrected by abstinence for 1 week. This aberrant glutathione homeostasis may contribute to enhanced alveolar permeability, thereby increasing susceptibility to the development of acute respiratory distress syndrome. In a rat model, chronic ingestion of ethanol decreased pulmonary glutathione concentration, increased alveolar barrier permeability, and increased the risk of acute lung injury. In alveolar type II cells, chronic ingestion of ethanol altered cellular functions such as decreased surfactant processing, decreased banner integrity, and increased sensitivity to cytotoxin-induced apoptosis in vitro and in vivo. In alveolar macrophages, chronic ingestion of ethanol decreased phagocytosis of microorganisms and decreased cell viability, events that would increase the risk of pneumonia. A central role for glutathione availability was demonstrated by the normalization of cellular function and viability of type II cells and macrophages as well as decreased sensitivity to endotoxemia-induced acute lung injury when glutathione precursors were added to the ethanol diet. These results support the suggestion that chronic ingestion of ethanol increased the risk of acute lung injury not through ethanol per se but through the chronic oxidative stress that resulted from ethanol-induced glutathione depletion. Because chronic oxidative stress alters cellular functions and viability, the lung becomes more susceptible when a second hit such as sepsis occurs.

Appendix A. dithioloquinolinethiones as new potential multitargeted antibacterial and antifungal agents: Synthesis, biological evaluation and molecular docking studies

Herein we report the design, synthesis, molecular docking study and evaluation of antimicrobial activity of ten new dithioloquinolinethiones. The structures of compounds were confirmed by 1H NMR, 13C NMR and HPLC-HRMS. Before evaluation of their possible antimicrobial activity prediction of toxicity was performed. All compounds showed antibacterial activity against eight Gram positive and Gram negative bacterial species. All compounds appeared to be more active than ampicillin and almost all than streptomycin. The best antibacterial activity was observed for compound 8c 4,4,8-trimethyl-5-{[(4-phenyl-5-thioxo-4,5-dihydro-1,3,4-thiadiazol-2-yl)thio]acetyl}-4,5-dihydro-1H-[1,2]dithiolo[3,4c]quino lone-1-thione). The most sensitive bacterium En.cloacae followed by S. aureus, while L.monocytogenes was the most resistant. All compounds were tested for antifungal activity also against eight fungal species. The best activity was expressed by compound 8d (5-[(4,5-Dihydro-1,3-thiazol-2-ylthio)acetyl]-4,4-dimethyl-4,5-dihydro-1H-[1,2]dithiolo[3,4-c]quinoline-1-thione). The most sensitive fungal was T. viride, while P. verrucosum var. cyclopium was the most resistant one. All compounds were more potent as antifungal agent than reference compound bifonazole and ketoconazole. The docking studies indicated a probable involvement of E. coli DNA GyrB inhibition in the anti-bacterial mechanism, while CYP51ca inhibition is probably responsible for antifungal activity of tested compounds. It is interesting to mention that docking results coincides with experimental.
