Two structurally isomeric azobenzene-and cholesteryl-based derivatives with varying alkyl chain lengths were developed as ALS-type gelators (N2 and N4) and synthesized and characterized spectroscopically. Of the two, N4 acted as a more efficient gelator than N2 since N4 could gel a larger number of solvents. The critical gelation concentration (CGC) of N4 was found to be less than that of N2 in the same solvent system. The morphological analyses of both gelators using SEM and TEM revealed that N4 exhibited self-assembled fibrous structures, whereas N2 exhibited spherical nanoparticles. The van der Waals interactions between the cholesteryl units, hydrogen bonding between the amide linkages and p-p stacking between the azobenzene units provided the driving force for the aggregation and gel formation. These driving forces were evidenced by temperature dependent H-1-NMR, FTIR and XRD analyses. Increasing the temperature of the gels shifted (upfield and downfield) the protons in the H-1-NMR spectra as well as the absorption bands in the FTIR spectra indicating that the intermolecular forces between the molecules became disrupted and caused gel -> sol transitions. These transitions were reversible after cooling to room temperature. Similarly, the gel -> sol transitions could be triggered by UV light (due to trans/cis isomerization); however, the transition was irreversible in the presence of visible light due to the formation of the more stable cis isomer. Hence, the gel state could be retained by heating and cooling the cis-conformation. In addition, the length of the molecule as determined by simulation software was found to match the values observed from the XRD analysis, and the interlayer distances were found to be 1.78 and 1.85 nm for N2 and N4, respectively. Based on this evidence, an aggregation mechanism was proposed. The differential scanning calorimetry (DSC) and polarized optical microscopy (POM) results revealed that both gelators exhibited grainy nematic mesophase textures during the heating and cooling cycles. These gelators underwent phase-selective gelation in the solvent mixtures containing gelling and nongelling solvents, which demonstrated the applicability of these gelators for the separation and purification of solvents.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 84358-13-4, in my other articles.

The present study deals with a gram-positive and rod-shaped bacterium SCRB 19 isolated from chromium contaminated tannery wastewater of common effluent treatment plant (CETP), Kanpur (U.P), India. Based on 16S rRNA gene sequencing investigation, the bacterium was recognized as Microbacterium paraoxydans. This bacterium exhibits relatively elevated tolerance to Cr(VI) (<= 1000 mg/L). The Cr(VI) reduction potential of isolated bacterium was studied at 100, 200 300 and 500 mg/L of Cr(VI) and the results revealed that bacterium reduced 93.45, 87.28, 72.01 and 39.24 % of Cr(VI) at their respective concentrations. The bacterial cell exterior showed the morphological changes and intracellular accumulation during the reduction of Cr(VI) was evidenced by SEM and EDX analysis. The Cr (VI) reduced product was bound with membrane functional groups such as amide and carboxyl group were determined through FTIR spectroscopy. The prominent peaks determined by XRD and XPS analysis corroborate the presence of possible reduced chromium species. The suspended culture of Microbacterium paraoxydans SCRB19 also showed chromate reductase enzyme activity of 1.603 +/- 0.041 U/mL. Hence, this strain can be a promising bio-agent for ecofriendly clean up strategies of toxic Cr(VI) from polluted environments.

Five new multicomponent solid forms of the biologically active 1,2,4-thiadiazole derivative (TDZH) with dicarboxylic and hydroxybenzoic acids have been discovered by combined virtual/experimental cocrystal screening. The interplay between the intrinsic hierarchy of the donor/acceptor groups in the TDZH/coformer molecules and the hydrogen bond pattern in the multicomponent crystals was rationalized using quantitative analysis of molecular electrostatic potential (MEP) surfaces along with periodic DFT computations. All the TDZH cocrystals are based on a carboxy-aminothiadiazole heterosynthon which is stabilized by a combination of enthalpic factors and the supramolecular chelating effect. According to the analysis of the non-covalent interaction energies, the mean energy value of this heterosynthon equals similar to 77 kJ mol(-1), which is comparable to the well-known carboxyl-amide and carboxyl-pyridine synthons in terms of the dissociation energy. The thermal stability of the multicomponent crystals was investigated by the DSC and TG methods. The pH-solubility behavior of the cocrystals was investigated at different pH values using eutectic concentrations of the components. Three out of five co-crystals were found to be more soluble than the parent TDZH at low pH values (approximate to 2.0). However, cocrystallization significantly alters the solubility-pH dependence of TDZH, increasing the compound solubility at neutral pH values.

We report that the nucleophilic acyl substitution reaction of aliphatic and (hetero)aromatic amides by organolithium reagents proceeds quickly (20 s reaction time), efficiently, and chemoselectively with a broad substrate scope in the environmentally responsible cyclopentyl methyl ether, at ambient temperature and under air, to provide ketones in up to 93 % yield with an effective suppression of the notorious over-addition reaction. Detailed DFT calculations and NMR investigations support the experimental results. The described methodology was proven to be amenable to scale-up and recyclability protocols. Contrasting classical procedures carried out under inert atmospheres, this work lays the foundation for a profound paradigm shift of the reactivity of carboxylic acid amides with organolithiums, with ketones being straightforwardly obtained by simply combining the reagents under aerobic conditions and with no need of using previously modified or pre-activated amides, as recommended.

The palladium-catalyzed Suzuki-Miyaura cross-coupling of N-acylsuccinimides as versatile acyl-transfer reagents via selective amide N-C bond cleavage is reported. The method is user-friendly since it employs commercially-available, air-stable reagents and catalysts. The cross-coupling is enabled by half-twist of the amide bond in N-acylsuccinimides. These highly effective, crystalline acyl-transfer reagents present major advantages over perpendicularly twisted N-acylglutarimides, including low price of the succinimide activating ring, selective metal insertion under redox neutral conditions and high stability of the amide bond towards reaction conditions. Mechanistic studies indicate that oxidative addition is the rate limiting step in this widely applicable protocol.

Antitubercular 7-substituted 2-nitroimidazo[2,1-b]-[1,3]oxazines were previously shown to exhibit potent antileishmanial and antitrypanosomal activities, culminating in a new clinical investigational drug for visceral leishmaniasis (DNDI-0690). To offset development risks, we continued to seek further leads with divergent candidate profiles, especially analogues possessing greater aqueous solubility. Starting from an efficacious monoaryl derivative, replacement of the side chain ether linkage by novel amine, amide, and urea functionality was first explored; the former substitution was well-tolerated in vitro and in vivo but elicited marginal alterations to solubility (except through a less stable benzylamine), whereas the latter groups resulted in significant solubility improvements (up to 53-fold) but an antileishmanial potency reduction of at least 10-fold. Ultimately, we discovered that O-carbamate 66 offered a more optimal balance of increased solubility, suitable metabolic stability, excellent oral bioavailability (100%), and strong in vivo efficacy in a visceral leishmaniasis mouse model (97% parasite load reduction at 25 mg/kg).

In this study, the soy protein was degraded and cross-linked with trimethylolpropane triglycidyl ether (THPTG) at 80 degrees C to prepare wood adhesive for interior plywood. Namely, by adding sodium hydroxide (NaOH), functional groups (-NH2, -COOH, and -OH) in soy protein were exposed and then reacted with epoxy groups to form a crosslinked water-resistance soy-protein adhesive under alkali condition. The optimum formulation of this adhesive was investigated. The molecular weights, chemical structure, bonding properties and water-resistance were characterized by gel permeation chromatography-multi-angle laser light scattering (GPC-MALLS), Fourier transform infrared spectroscopy (FTIR), plywood bonding test and three-cycle soak test. Results showed that at 2% NaOH, the molecular weight of soy protein isolate degradation (DSP) presented as 3.473e + 04 g center dot mol(-1) was homogeneous and resulted in greater increase of amide II and amide III. The cross-linking reaction between THPTG and DSP resulted in the increase of both viscosity and sensitivity of infrared absorption peaks of -O-H (3100 cm(-1)) and C-N (1190 cm(-1)). Also, the adhesives synthesized from the SPI denatured with 2% NaOH and 9% THPTG did meet the wet strength for interior-use plywood panels (>= 0.7 MPa) according to the China Industry Standard GB/T 9846.3-2004 and water resistance according to American National Standard for Hardwood and Decorative Plywood/Hardwood Plywood and Veneer Association.
