Structural characterization and QSAR modeling of 1,2,4-triazole derivatives as alpha-glucosidase inhibitors

In order to identify potential new drugs that could be useful in preventing and treating diabetes, we benchmarked several exchange-correlation functionals and ab initio methods to accurately describe the structural, electronic and vibrational properties of 1,2,4-triazole (Tz) and 1,2,4-triazolone (TzO). This theoretical approach was employed to develop a QSAR model to correlate the quantum chemical descriptors of 1,2,4-triazolone derivatives with their antidiabetic activity. The best statistically significant correlations between the biological activity and the descriptors were generated after a multiple linear regression (MLR) analysis. A QSAR model was successfully developed and a good correlation between the experimental and predicted activity values was described.

Neutral Chiral Tetrakis-Iodo-Triazole Halogen-Bond Donor for Chiral Recognition and Enantioselective Catalysis

Halogen bonding represents a powerful tool in the field of noncovalent interactions. However, applications in enantioselective recognition and catalysis remain almost nonexistent, due in part to the distinct features of halogen bonds, including long covalent and noncovalent bond distances and high directionality. Herein, this work presents a novel chiral tetrakis-iodo-triazole structure as a neutral halogen bond donor for both chiral anion-recognition and enantioinduction in ion-pair organocatalysis. NMR-titration studies revealed significant differences in anion affinity between the halogen bonding receptor and its hydrogen bonding parent. Selective recognition of chiral dicarboxylates and asymmetric induction in a benchmark organocatalytic reaction were demonstrated using the halogen bond donor. Inversions in the absolute sense of chiral recognition, enantioselectivity, and chiroptical properties relative to the related hydrogen donor were observed. Computational modeling suggested that these effects were the result of distinct anion-binding modes for the halogen- versus hydrogen-bond donors.

Effect of Alkyl Side Chains of Polymer Donors on Photovoltaic Performance of All-Polymer Solar Cells

In this manuscript, we investigate the effect of alkyl side chains of polymer donors on photovoltaic performance of all-polymer solar cells (all-PSCs) based on polymer acceptors containing a boron-nitrogen coordination bond (B <- N). We develop three polymer donors, CD-C12, CD-C16, and CD-C20, with 4,8-di(thiophen-2-yl)benzo[1,2-b:4,5-b']dithophen-alt-5,6- difluoro-7-(thiophen-2-yl)-2H-benzo [d][1,2,3]triazole as the main chain and 2-butyloctyl, 2-hexyldecyl, and 2-octyldodecyl as the side chains, respectively. The three polymer donors exhibit similar LUMO/HOMO energy levels and similar absorption spectra. However, they show different aggregation tendency in solution and different solid stacking properties. Among the three polymers, CD-C16 containing medium-length alkyl side chains exhibits the strongest aggregation behavior in solution and much enhanced crystallinity in films. The three polymer donors are blended with a B <- N-based polymer acceptor PBN-14 to prepare all-PSCs. The device of CD-C16 with medium-length alkyl side chains shows small-size phase separation, which leads to a power conversion efficiency (PCE) of up to 9.8%. In comparison, the active layers of CD-C12 and CD-20 show large-scale phase separation and decreased PCEs of the devices. The optimal all-PSC device performance of CD-16 is ascribed to the strong aggregation behavior of polymer backbones in solution and the high crystallinity, which inhibit the oversized crystals of the polymer acceptor and lead to ideal phase separation morphology of the donor/acceptor blend. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

Bis-BODIPY linked-triazole based on catechol core for selective dual detection of Ag+ and Hg2+

Herein, we introduced a new chemosensor, bis-BODIPY linked-triazole based on catechol (BODIPY-OO) prepared by bridging two units of BODIPY fluorophore/triazole binding group with a catechol unit. A solution of this compound displayed 4- and 2-fold enhancements in fluorescence intensity after adding a mole equivalent amount of Ag+ and Hg2+ ions in methanol media, respectively. H-1 NMR titrations of BODIPY-OO with Ag+ and Hg2+ suggested that the triazole was involved in the recognition process. BODIPY-OO showed high sensitivity toward Ag+ and Hg2+ over other metal ions with detection limits of 0.45 mu M and 1 mu M, respectively. It can also distinguish Hg2+ from Ag+ by addition of an EDTA. This compound can therefore be employed as practical fluorescent probe for monitoring the presence of Ag+ and Hg2+ ions.

Theoretical study of effects of introducing varying linkages into bis-triazoles on energetic performance

A series of novel bis-triazole compounds was designed by combining high-energy functionalities (nitro and nitramino groups) as substituents with each triazole and incorporating of varying linkages into the bis-triazoles. Then, their heats of formation (HOFs), energetic properties, HOMO-LUMO, electrostatic potential, and impact sensitivity were studied theoretically to facilitate further developments. In general, all the designed compounds possess much higher HOFs than RDX, -CH2-CH2-, -N=N-, or -NH-NH- linkages contribute to increase the HOFs, while incorporation of the bridge group -O-CH2-CH2-O- shows negative effect on HOFs. Detonation properties of most of the designed compounds can be comparable with or even better than ones of RDX, suggesting that designing the bridged bis-triazoles-based derivatives with energy-rich substituents is an efficient method to obtain potential energetic compounds. Considering the detonation performance and impact sensitivity, -NH-(I), -N=N- (V), and -NH-NH- (VI) are favorable bridged groups between energetic moieties for designing efficient energetic materials (EMs).

Synthesis and energetic properties of homocubane based high energy density materials

The energetic properties of homocubane derivatives have been evaluated for the first time. The newly synthesized compounds have been fully characterized by spectroscopic methods and single crystal X-ray analysis. Detailed computational studies carried out using the B3LYP/6-311++G(d,p) level of theory reveal that these compounds have higher densities and higher heat of formation as compared to common hydrocarbon fuels. The calculated performances of these compounds in terms of their ballistic properties, particularly density specific impulse (rho I-sp), in liquid and in solid propellant systems are substantially superior to those of the conventional fuel RP1 and binder HTPB, respectively. TGA-DTG analysis confirmed that most of these compounds are thermally stable with high onset temperatures. Most of the compounds, except oxadiazole, triazole and triazine containing cages, are also kinetically stable in terms of their HOMO-LUMO energy gap. Quite remarkably, three compounds emerged as excellent candidates for volume-limited applications owing to their high density, density specific impulse as well as kinetic and thermodynamic stabilities.

Impact of benzimidazole resistance on fitness parameters and fumonisin B1 production in Fusarium verticillioides (Sacc) Niremberg

Fusarium verticillioides laboratory isolates resistant to carbendazim were readily obtained after mutagenesis with UV-irradiation. Three resistant phenotypes that included highly (HR, Resistant factors>30), moderately (MR, Rf: 14-25) and low (LR, Rf: 2-5) resistant isolates to carbendazim were identified by fungitoxicity tests in vitro. Mutant isolates were simultaneously resistant to thiabendazole and benomyl but not to the also tubulin-blocking fungicides diethofencarb and zoxamide. No cross resistance relationship was found between carbendazim and fungicides with different modes of action such as the dicarboximide iprodione, the QoI pyraclostrobin, the imidazole prochloraz, the triazoles flusilazole and epoxiconazole. Mutation(s) for resistance to benzimidazoles did not significantly affect mycelial growth rate whereas sporulation and pathogenicity were adversely affected in most of the resistant mutants. Moreover, low temperatures suppressed the expression of carbendazim-resistance in all resistant phenotypes. Most mutant isolates produced Fumonisin B1 in similar or less quantities than the wild-type isolate both in vitro and in vivo in the absence of carbendazim with the exception of one HR isolate which had up to 3-fold increased FB1 production. Sub lethal doses of carbendazim in the growth medium in vitro resulted in a significant reduction in FB1 levels in all cases even though most mutant isolates produced higher FB1 quantities than the wild type. A significant correlation was found between F. verticillioides sporulation and FB1 production on maize seeds. The potential risk of food and feed contamination by FB1 producing F. verticillioides isolates resistant to benzimidazoles and implications on resistance management strategies are discussed.

Synthesis of novel 1,2,3-triazoles bearing 2,4 thiazolidinediones conjugates and their biological evaluation

Searching for new active molecules against M. Bovis BCG and Mycobacterium tuberculosis (MTB) H37Ra, a focused of 1,2,3-triazoles-incorporated 2,4 thiazolidinedione conjugates have been efficiently prepared via a click chemistry approach cyclocondensation of 4-amino-N-(5-methylisoxazol-3-yl)benzenesulfonamide (4), aryl aldehyde (5a-l), and mercapto acetic acid (6) with good to promising yields. The newly synthesized compounds were tested against drug-sensitive MTB and BCG. In particular, compounds 8g, 8h, 8j and 8l are highly potent against both the strains with IC90 values in the range of 1.20-2.70 and 1.24-2.65 mu g/mL, respectively. Based on the results from the antitubercular activity, SAR for the synthesized series has been developed. Most of the active compounds were non-cytotoxic against MCF-7, HCT 116 and A549 cell lines. Most active compounds were having a higher selectively index, which suggested that these compounds were highly potent.
