5,10,15,20-tetra(4-aminophenyl)porphyrinatonickel(II) was covalently connected to multi-walled carbon nanotube (MWCNT) through an amide linkage and characterized by using many spectroscopic techniques. In FT-IR, the carbonyl peak (C = O) of MWCNT-NiTAP is shifted to higher frequency as compared to the reported MWCNT-TAP due to Ni ion substitution. Notable changes in the FT-IR and XP spectra confirms the covalent functionalization of Ni-TAP with MWCNTs. Raman spectra indicate that the ID/IG ratio is less for MWCNT-NiTAP as compared to MWCNT, MWCNT-COOH, MWCNT-ZnTAP and MWCNT-CuTAP which is due to improved electronic properties of MWCNT-NiTAP. TGA plots of MWCNT-NiTAP reveals that similar to 30% weight loss in the temperature range of 150-800 degrees C. Considerable shift in the absorption and emission spectra of the nano hybrid clearly indicate different electronic interaction between porphyrin and MWCNT due to nickel ion substitution. PL spectra of MWCNT-NiTAP exhibited fluorescence quenching of Ni-TAP Soret band by MWCNTs. This quenching is owing to the energy or electron transfer between Ni-TAP and MWCNTs.

This study investigates the effect of agar addition and ultrasound treatment on the properties of edible films made from smooth hound (Mustellus mustellus) skin gelatin. The FTIR spectra showed the classic profile of gelatin spectrum presenting three characteristic absorption peaks related to amide I (1620-1690 cm(-1)), amide II (1540-1580 cm(-1)) and amide III (1230-1280 cm(-1)). The agar addition or ultrasound treatment did not cause important influence on FTIR spectra. Agar addition resulted in an improvement of the film rigidity, since blended films of gelatin:agar (25:75) showed important increase of the film tensile strength (12.3 MPa) and a decrease in elongation at break (135%), as compared to the 100% gelatin-based films. All the films were colorless ( increment E < 6.8 and opacity < 2.5) and agar addition resulted in a slight increase of the L* values of the blended films that become more transparent. The ultrasound treatment had no significant effect on the mechanical and color properties. The water contact angle was increased for the blended films, which imply the increase of their hydrophobicity. At 120 s the increase in water contact angle was 11.5 and 36.6% for the gelatin:agar (50:50) and (25:75) films, respectively, as compared to the 100% gelatin-based film that suggested a decrease in surface hydrophilicity of the blended films. Agar addition (gelatin:agar; 25:75) decreased the film water solubility by 34%, which suggested that agar could improve their water resistance. Overall, agar addition improved barrier properties of smooth hound gelatin films encouraging their use as a food packaging material. But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 87-32-1, you can contact me at any time and look forward to more communication.

A novel in vitro anti-tumor protein (J2-C2) with a molecular weight of 27,153.0Da was isolated from the edible portion of Arca inflata. Physical and structural properties of J2-C2 were characterized using physicochemical and instrumental analyses. Gel electrophoresis analysis showed that J2-C2 is a homogeneous, monomeric protein with an isoelectric point of 6.3. The purity of the isolated native J2-C2 was >99%, as determined by RP-HPLC. The carbohydrate content assay showed that J2-C2 was not a glycoprotein. The FT-IR spectrum of J2-C2 gave characteristic amide absorption bands at 1645.71 and 1541.46 cm(-1). Secondary structure analysis by CD spectroscopy revealed that J2-C2 had 34.0% alpha-helix, 27.5% beta-sheet, 13.4% beta-turn and 25.1% random coil. In-gel and nano ESI-MS/MS sequencing analysis combined with transcriptome unigene analysis yielded the complete amino acid sequence of J2-C2. Aligning with NCBI BLAST database, J2-C2 showed 77% homology with predicted triosephosphate isomerase (TIM) derived from Crassostrea gigas. Therefore, J2-C2 was considered to be a new TIM-like protein in A. inflata. The anti-tumor effect of J2-C2 against three human tumor cells was measured by MTT assay, and the IC50 values of J2-C2 were 42.38, 45.64 and 48.73 mu M against A549, HepG2 and SPC-A-1 cell lines, respectively.

The synthesis of organic-inorganic hybrid materials using individual metal-organic molecules as building blocks has been of interest for the last few decades. These hybrid materials are appealing due to the opportunities they provide with respect to a variety of potential applications. Here, we report a novel metal-organic nanostructure made by a hybrid synthetic process that is comprised of thermal evaporation (TE) and atomic layer deposition (ALD) for the metalation of an organic layer. In this work, 5,10,15,20-tetrakis(4-hydroxyphenyl)-21H,23H-porphyrin (p-(H-6)THPP) and tin(ii) bis(trimethylsilyl)amide (Sn(btsa)(2)) (or diethylzinc (DEZ)) were utilized as the main organic layer and ALD precursors, respectively. Sn and Zn atoms were coordinated sequentially via surface chemical reactions on specific functional groups of the p-(H-6)THPP layer, which was deposited on a solid substrate. X-ray photoelectron spectroscopy (XPS) and UV-vis absorption spectroscopy were used to characterize and confirm the growth mechanism and optical properties of the synthesized hybrid films. This method should serve as a major breakthrough for building advanced organic-inorganic materials-based devices.

Highly-conductive two-dimensional covalent organic framework (COF) displays prominent applications in various fields of science and technology. This paper reports the design and liquid-liquid interface synthesis of a novel Zr-coordinated amide porphyrin-based 2D COF (Zr-amide-Por-based 2D COF). The COF adopts a graphenelike multilayer structure with the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) band gap of 1.6 eV. The ordered multilayer structure of the amide COF was confirmed through a series of characterization techniques, including scanning electron microscopy, high-resolution transmission electron microscopy, atomic force microscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. In particular, the inherent-ordered structure of Zr-amide-Por-based 2D COF with Zr as the catalytically active center confers several distinct advantages to the material, such as high conductivity and high electrocatalysis performance. A molecularly imprinted tetracycline electrochemiluminescence sensor was constructed based on the Zr-amide-Por-based 2D COF, and gate control effect was used as a signal-generation mechanism. Under optimal conditions, the sensor showed a good linear relationship with tetracycline in the concentration range of 5-60 pM, with a detection limit of 2.3 pM. Because the sensor is rapid, cost-efficient, highly sensitive, and specific, it can be considered as a viable platform for veterinary drug residue monitoring.

Aggregation of proteins has been related to some neurodegenerative diseases such as Alzheimer’s and Parkinson’s among others. Raman spectroscopy is a useful technique for the investigation of protein conformation and of changes in their secondary structure. In this study, a surface enhanced Raman spectroscopy (SERS) substrate based on the immobilization of plasmonic gold nanostars on a glass slide via silanization of the surface has been prepared and characterized. Gold nanostars were synthesized via a seed-growth method using gold nanoparticles as seeds obtained via stainless steel as the reducing agent. The plasmonic substrate provided an enhancement of 5.7 x 10(2 )fold, as shown for the Raman signal of crystal violet. Using this SERS-active substrate, the investigation of aggregation processes of bovine serum albumin (BSA) and myoglobin proteins upon temperature and solvent modification has been enabled with enhanced sensitivity. Both curve fitting and deconvolution of the amide I band, as well as 2D correlation analysis, were employed for the evaluation of the changes in the SERS spectra of the protein samples. The amide I band within the SERS spectra of the BSA protein revealed a decrease in the alpha-helix structures within the secondary structure of the protein while the presence of beta-sheet structures increased with temperature and solvent concentration.

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).

Treatment of the ortho-triazacyclophane 1,4-dimethyltribenzo[b,e,h][1,4,7] triazacyclonona- 2,5,8-triene [(C6H5)(3)(NH)(NCH3)(2), L1] with Fe[N(SiMe3)(2)](2) yields the dimeric iron(II) complex bis(mu-1,4-dimethyltribenzo[b,e,h][1,4,7] triazacyclonona- 2,5,8-trien-7-ido) bis[(mu -1,4-dimethyltribenzo[b,e,h][1,4,7] triazacyclonona- 2,5,8-trien-7-ido) iron(II)], [Fe(C20H18N3)(4)] or Fe-2(L1)(4) (9). Dissolution of 9 in tetrahydrofuran(THF) results in solvation by two THF ligands and the formation of a simpler monoiron complex, namely bis(mu-1,4-dimethyltribenzo[b,e,h][1,4,7] triazacyclonona-2,5,8-trien-7-ido-kappa N-7) bis(tetrahydrofuran- kappa O) iron(II), [Fe(C20H18N3)(2)(C4H8O)(2)] or(L1)(2)Fe(THF)(2) (10). The reaction is reversible and 10 reverts in vacuo to diiron complex 9. In the structures of both 9 and 10, the monoanionic triazacyclophane ligand L1(-) is observed in only the less-symmetric saddle conformation. No bowl-shaped crown conformers are observed in the solid state, thus preventing chelating kappa(3)-coordination to the metal as had been proposed earlier based on density functional theory(DFT) calculations. Instead, the L1(-) ligands are bound in either a eta(2)-chelating fashion through the amide and one amine donor(for one of the four ligands of 9), or solely through their amide N atoms in an even simpler monodentate eta(1)-coordination mode. Density functional calculations on dimer 9 revealed nearly full cationic charges on each Fe atom and no bonding interaction between the two metal centers, consistent with the relatively long Fe center dot center dot center dot Fe distance of 2.912(1) angstrom observed in the solid state.
