Engineered (Lys)(6)-Tagged Recombinant Sulfide-Reactive Hemoglobin I for Covalent Immobilization at Multiwalled Carbon Nanotubes

The recombinant HbI was fused with a poly-Lys tag ((Lys)(6)-tagged rHbI) for specific-site covalent immobilization on two carbon nanotube transducer surfaces, i.e., powder and vertically aligned carbon nanotubes. The immobilization was achieved by following two steps: (1) generation of amine-reactive ester from the carboxylic acid groups of the surfaces and (2) coupling these groups with the amine groups of the Lys-tag. We analyzed the immobilization process using different conditions and techniques to differentiate protein covalent attachment from physical adsorption. Fourier transform infrared microspectroscopy data showed a 14 cm(-1) displacement of the protein’s amide I and amide II peaks to lower the frequency after immobilization. This result indicates a covalent attachment of the protein to the surface. Differences in the morphology of the carbon substrate with and without (Lys)(6)-tagged rHbI confirmed protein immobilization, as observed by transmission electron microscopy. The electrochemical studies, which were performed to evaluate the redox center of the immobilized protein, show a confinement suitable for an efficient electron transfer system. More importantly, the electrochemical studies allowed determination of a redox potential for the new (Lys)(6)-tagged rHbI. The data show that the protein is electrochemically active and retains its biological activity toward H2S.

Diastereoselective Acylation of Racemic Heterocyclic Amines with N-Phthaloyl and N-Naphthaloyl (S)-Amino Acyl Chlorides: Possibility of Parallel Kinetic Resolution

The acylative kinetic resolution of racemic 2-methyl-1,2,3,4-tetrahydroquinoline and 3,4-dihydro-3-methyl-2H-[1,4]benzoxazines with acyl chlorides of N-naphthaloyl-(S)-alanine and N-naphthaloyl-(S)-phenylalanine has been studied. It has been shown that diastereoselective acylation of racemic amines with N-naphthaloyl (S)-amino acyl chlorides results in the predominant formation of (R,S)-amides, whereas acylation of the same amines with N-phthaloyl (S)-amino acyl chlorides proceeds with the opposite diastereoselectivity. The parallel kinetic resolution of racemic 3,4-dihydro-3-methyl-2H-[1,4]benzoxazine using a mixture of acylating agents derived from a single precursor, (S)-phenylalanine, was carried out.

Evaluating the rote of a urea-like motif in enhancing the thermal and mechanical strength of supramolecular gels

The geometry and spatial orientation of gelator molecules and the mode of various intermolecular non-covalent interactions are the key parameters that dictate the structure and properties of low molecular weight gelators (LMWGs). The effect of intermolecular non-covalent interactions in tuning the gelation properties was analysed for dipyridyl hydrazone (HL1) with an amide-like hydrogen bonding moiety and semicarbazone (HL2) with a urea-like motif. The gelation properties of the hydrazone and semicarbazone compounds were studied in a series of solvents and solvent mixtures and the SEM images of the xerogels revealed that the morphology of the HL2 gelator was more fibrous in nature compared to HL1. The mechanical and thermal stability of HL2 was higher than HL1, which was confirmed by rheology and gel-sol transition temperature experiments, respectively. The key non-covalent interactions responsible for gel formation were assigned using X-ray diffraction techniques and the results were corroborated with the gelation properties. The stimuli-responsive properties of the gelators were studied by analysing the effect of metal salts and anions on the gelation properties of HL1 and HL2 and the results indicated that metal complexation disrupted the gel network whereas the addition of anions did not alter the gelation ability of the gelators. The tuning of gelation properties by metal complexation and the comparison of intermolecular non-covalent interactions of the gelators enabled us to identify the key parameters responsible for gel-network formation in HL1 and HL2.

Diphenylsilane as a coupling reagent for amide bond formation

A simple procedure for amide bond formation using diphenylsilane as a coupling reagent is described. This methodology enables the direct coupling of carboxylic acids with primary and secondary amines, releasing only hydrogen and a siloxane as by-products. Only one equivalent of each partner is needed, providing a more sustainable amidation method producing minimal wastes. This methodology was also extended to the synthesis of peptides and lactams by addition of Hunig’s base (DIPEA) and 4-dimethyl-aminopyridine (DMAP).

Synthesis of Rhizopus arrhizus Lipase Nanoparticles for Biodiesel Production

We developed a nanoparticulate Rhizopus arrhizus lipase formulation to enhance its activity and to increase the conversion yield of lipids into fatty acid methyl esters (FAME, a. k. a., biodiesel). More than 95% purity of the lipase was achieved in a two-step purification. Nanoparticle formulation was afforded by co-lyophilization of the lipase with methyl-beta-cyclodextrin (M beta CD), an established lyoprotectant. Scanning electron microscopy and dynamic light scattering measurements showed a size of 75200 nm for the nanoparticles depending on the ratio of lipase-to-M beta CD employed during co-lyophilization. Fourier transform infrared spectroscopic analysis by Gaussian curve fitting of the resolution-enhanced amide I region of lyophilized and nanoparticulate lipase indicated a more native-like secondary structure in the latter. A 98% substrate-to-FAME conversion was achieved in 10 h in n-hexane by lipase nanoparticles, whereas the crude and lyophilized enzyme showed 65 and 70% conversion in 18 h, respectively. In this aspect, the lipase nanoparticles were superior to all other reported systems. Operational stability after 5 catalytic conversions of nanoparticles was found to be > 81%. In summary, we herein developed a novel lipase formulation for efficient catalysis in lipid-to-biodiesel conversion.
