Obtucarbamate A was purified from Disporum cantoniense with good antitussive property. In present work, a series of obtucarbamate A derivatives were designed and synthesized from obtucarbamate A by microwave method, and their antitussive activity were evaluated. The results showed that the toluene diisocyanate was obtained with a yield of 95.1% using a simple method, 1-methyl-2-pyrrolidinone as solvent, temperature of 190 degrees C, microwave irradiation at 60 W power for 30 min. All compounds have good antitussive activity, and small steric hindrance unsaturated groups of ester chains and amino groups favor activity. It is the first reported of obtucarbamate A derivatives used as antitussive, and the results provide a basis for the application of obtucarbamate derivatives as new antitussive.

Anoectochilus roxburghii (Wall.) Lindl. (Orchidaceae) or more commonly known as Jin Xian Lian is a widely adapted medicinal herb in the Asian continent. However, till date there are limited rapid analytical method such as thin layer chromatography method that acts as standard for quantifying the active ingredients of A. roxburghii. In this research, a simple and rapid method high performance thin layer chromatography (HPTLC)-anisaldehydesulfuric acid derivative with iterative calibration method was developed and validated to quantify the non UV sensitive bioactive compound kinsenoside in wild, cultivated and tissue cultured A. roxburghii plants. The optimum mobile phase identified for kinsenoside in A. roxburghii was chloroform/methanol/water (45:30:4,%v/v/ v). It was also proved that HPTLC method for determination of kinsenoside showed good accuracy, precision, stability and repeatability, with wide working concentration range of 0.099?6.365 mg/mL. Intra-day and interday precision (% RSD) of the developed HPTLC method were 5.08?7.57% and 6.72?8.72%, respectively. The % RSD of iterative calibration method was 3.139%. Through this study, it can be concluded that the proposed HPTLC method with iterative calibration approach was successfully applied for quantitative analysis of kinsenoside in three types of A. roxburghii plants.

The radiation-induced reactions of ligands play an important role in the sensitization of metal oxide nanocluster resists. However, the details in the radiation chemistry of ligands for metal oxide nanocluster resists are still unknown. In this study, the radiation-induced reactions of carboxylic acid ligands were investigated using a pulse radiolysis method. The rate constants for the reactions of molecular and ionic forms of tiglic, angelic, o-toluic, and p-toluic acids with hydrated electrons were determined. The rate constants for the reactions of tiglic, angelic, benzoic, o-toluic, and p-toluic acids with dodecane radical cations were also determined. The radical ions of tiglic and angelic acids were more unstable than those of benzoic, o-toluic, and p-toluic acids. The results obtained in this study indicate that the molecular structures of ligands affect their reactivity to cationic and anion species and the stability of their radical cations and anions.

All the four compounds were characterized by single-crystal X-ray diffraction, powder X-ray diffraction (XRD), IR spectroscopy, thermogravimetric analysis (TGA), and X-ray photoelectron spectroscopy (XPS). These compounds can serve as efficient heterogeneous catalysts for the cyanosilylation of different carbonyl compounds under ambient temperature and solvent-free conditions, and Cu-POM shows much better catalytic performance than the other three compounds. The cycle experiment showed that Cu-POM can be reused for at least five cycles without significant loss of catalytic activity. The IR spectroscopy and XRD analysis revealed that Cu-POM can retain its integrity after catalysis.

An adequate enhancement in the development of resistance by microbial pathogens against the available chemotherapeutic agents prompted us to find out some new chemotherapeutic agents with significant therapeutic effect as antimicrobials. The present study reported the designing of 6-(1H-indol-3-yl)-4,5 ‘-bipyrimidine-2-amine (2) and its Schiff’s bases (3-12), and the computational studies were performed to assess properties (drug likeness and physicochemical). The computationally bioactive compounds (1-12) were then followed for synthesis, characterization, antimicrobial therapeutic effect and percent viability of cells. The antimicrobial therapeutic effect was obtained by disk diffusion method, in terms of zone of inhibition and minimum inhibitory concentration against the gram-positive and gram-negative bacteria [S. aureus (ATCC-25923), S. epidermidis (ATCC-29887)], [E. coli (ATCC-25922), P. mirabilis (ATCC-25933)]. The antimicrobial screening findings reveled that all the compounds (1-12) possessed very good activity and strongly recommended the computational results. The antibiotic ciprofloxacin and the solvent DMSO were used as positive and negative control in the study. The percent viability of the cells was observed using HepG2 cells by MTT assay and noticed that the percent viability of the cells was found in the range 93-97% at lowest concentration 3.125 mu M while 73-77% at the highest 100 mu M. All the compounds (1-12) and ciprofloxacin were then applied for molecular docking assessment to estimate the H-bonding with the residues of GlcN-6-P-synthase, and the findings revealed that significant H-bonding was observed with the binding affinity in the range of – 8.4 to 6.7 kcal/mol and – 7.6 to 6.0 kcal/mol, respectively.

Hydrogen sulfide (H2S) is a critical gasotransmitter playing an important role in various physiological and pathological processes. The development of fluorescent probes for rapid, sensitive, and selective lysosomal H2S sensing has attracted much attention. Herein we report a rhodamine based probe MF-N-3 that can selectively accumulate in lysosomes and give turn-on fluorescence in the presence of both H2S and protons. Results show that MF-N-3 has an exclusive response to H2S in the acidic lysosomal environment but does not respond in other organelles or in neutral environments. This strategy can circumvent the fluorescence interference from H2S of other sources, thus providing a high sensitivity and selectivity on lysosomal H2S imaging by fluorescence microscopy. This pH-dependent lysosome-targeting fluorescent probe has been successfully applied to lysosomal H2S imaging in living cells and is of great potential for applications to the environmental and biological systems.

A virtual screening conducted with nearly 4 000 000 compounds from lead-like and fragment-like subsets enabled the identification of a small-molecule inhibitor (1) of the Trypanosoma cruzi cruzain enzyme, a validated drug target for Chagas disease. Subsequent comprehensive structure-based drug design and structure-activity relationship studies led to the discovery of carbamoyl imidazoles as potent, reversible, and competitive cruzain inhibitors. The most potent carbamoyl imidazole inhibitor (45) exhibited high affinity with a K-i value of 20 nM, presenting both in vitro and in vivo activity against T. cruzi. Furthermore, the most promising compounds reduced parasite burden in vivo and showed no toxicity at a dose of 100 mg/kg. These carbamoyl imidazoles are structurally attractive, nonpeptidic, and easy to prepare and synthetically modify. Finally, these results further advance our understanding of the noncovalent mode of inhibition of this pharmaceutically relevant enzyme, building strong foundations for drug discovery efforts.

We have investigated the stereoselective formation of spiro oxindole pyrrolidines via formal [3+2] cycloaddition of oxindole imines with ketoesters and ketoamides. Bifunctional squaramide organocatalyst was able to induce enantioselectivity of up to 60 % ee, increased to 72 % ee after re-crystallization, in the formation of spiro pyrrolidines with ketoesters. Interestingly, ketoamides provided alternative spiro oxindole pyrrole products in addition to the main product, which was formed via a different reaction pathway. Structures of spiro oxindole pyrrolidine as well as pyrrole products were confirmed by X-ray crystallographic analysis. Two new squaramide based catalysts were synthesized and tested. DFT calculation helped elucidate the reaction course.

The potent nucleophilicity and remarkably low basicity of 1,3,2-diazaphospholenes (DAPs) is exploited in a catalytic, metal-free 1,4-reduction of free alpha,beta-unsaturated carboxylic acids. Notably, the reduction occurs without a prior deprotonation of the carboxylic acid moiety and hence does not consume an additional hydride equivalent. This highlights the excellent nucleophilic character and low basicity of DAP-hydrides. Functional groups such as Cbz group or alkyl halides which can be problematic with classical transition-metal catalysts are well tolerated in the DAP-catalyzed process. Moreover, the transformation is characterized by a low catalyst loading, mild reaction conditions at ambient temperature as well as fast reaction times and high yields. The proof-of-principle for a catalytic enantioselective version is described.
