Propargyl-15(2),17(3)-dimethoxy-13(1)-amide of bacteriochlorin e (BChl) and a 4-(4-N, N-dimethylaminostyryl)-N-alkyl-1,8-naphthalimide bearing azide group in the N-alkyl fragment were conjugated by the copper(I)-catalyzed 1,3-dipolar cycloaddition to produce a novel dyad compound BChl-NI for anticancer photodynamic therapy (PDT) combining the modalities of a photosensitizer (PS) and a fluorescence imaging agent. A precise photophysical investigation of the conjugate in solution using steady-state and time-resolved optical spectroscopy revealed that the presence of the naphthalimide (NI) fragment does not decrease the photosensitizing ability of the bacteriochlorin (BChl) core as compared with BChl; however, the fluorescence of naphthalimide is completely quenched due to resonance energy transfer (RET) to BChl. It has been shown that the BChl-NI conjugate penetrates into human lung adenocarcinoma A549 cells, and accumulates in the cytoplasm where it has a mixed granular-diffuse distribution. Both NI and BChl fluorescence in vitro provides registration of bright images showing perfectly intracellular distribution of BChl-NI. The ability of NI to emit light upon excitation in imaging experiments has been found to be due to hampering of RET as a result of photodestruction of the energy acceptor BChl unit. Phototoxicity studies have shown that the BChl-NI conjugate is not toxic for A549 cells at tested concentrations (<8 mu M) without light-induced activation. At the same time, the concentration-dependent killing of cells is observed upon the excitation of the bacteriochlorin moiety with red light that occurs due to reactive oxygen species formation. The presented data demonstrate that the BChl-NI conjugate is a promissing dual function agent for cancer diagnostics and therapy.

Fourier transform infrared imaging (FTIRI) can be used to obtain the composition and structure information of sample. Here, FTIRI combined with spectral polarization analysis method was applied to investigate the fine anisotropy of bovine nasal cartilage (BNC). The upper BNC tissue was sliced into a three-dimensional (3D) block with three planes (XY, YZ, and XZ) parallel to horizontal section, forward section, and lateral section, respectively. The anisotropy of collagen fiber in BNC was represented by the absorbance of amide II (1590-1500 cm(-1)) at different polarization directions. It was found that collagen fiber showed little anisotropy in plane XY, XZ, and along the direction Z in plane YZ. It was more important that collagen fiber showed strong anisotropy along direction Y in plane YZ (transverse axis) of BNC, possibly including arched or wavy fiber orientation even a mixture of both in nasal septum top end. Two anisotropic deflections ranging from 600 to 930 mu m and from 2680 to 2980 mu m were quantitatively calculated. This study is of important significance for further understanding the physiological structure of nasal septum and provides remarkable experimental support for being a good transplant material in cartilage reshaping studies.

Chemistry is the experimental science by definition. We want to make observations to prove hypothesis.

The cobalt(I) pincer complex, [Co(N-2)-((PNP)-P-cy)] ((cy)pNP = anion of 2,5-bis-((dicyclohexylphosphino)methyl)pyrrole), reacts with aromatic, vinylic, and aliphatic aldehydes to produce the corresponding hydrocarbon products and [Co(CO)-((PNP)-P-cy)]. The pathway for aldehyde decarbonylation is found to involve initial coordination of the aldehyde to Co(I), followed by oxidative addition of the C-H bond to produce a cobalt(III) acyl hydride. The acyl hydride species then undergoes CO deinsertion, followed by reductive elimination to afford the decarbonylated product and [Co(CO)((PNP)-P-cy)]. Reactions of [Co(N-2)((PNP)-P-cy)] with other carbonyl containing groups such as carboxylic acids and amides also proceed via oxidative addition to give Co(III) intermediates arising from activation of the X-H (X = 0 or NH) bond. In these cases, however, the Co(III) species extrude molecular hydrogen to produce Co(II) species of the form [Co(X{O}CR)((PNP)-P-cy)] (X = O or NH). The ability of [Co(N-2)((PNP)-P-cy)] to undergo facile oxidative addition is discussed in the context of potential bond activation processes mediated by well-defined Co species.

Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 3211-76-5, Name is L-SelenoMethionine, molecular formula is , belongs to amides-buliding-blocks compound.

The syntheses of zinc(II) tetra-[3-(4-phenoxy) (propanoic acid) phthalocyanine] (2) and zinc(II) mono[3-(4-phenoxy) (propanoic acid) phthalocyanine (3) are reported in this work. Compounds 2 and 3 were covalently linked to glutathione capped silver (AgNPs-GSH), gold (AuNPs-GSH) and silver-gold alloy (Ag(3)Au(1)NPs-GSH) nanoparticles (NPs) via an amide bond formation to afford the conjugates: 2-AgNPs-GSH, 3-AgNPs-GSH, 2-AuNPs-GSH, 3-AuNPs-GSH, 2-Ag(3)Au(1)NPs-GSH and 3-Ag(3)Au(1)NPs-GSH. The photophysicochemical behaviours of the compounds and their conjugates with NPs were assessed in solution. The conjugates afforded a decrease in fluorescence quantum yields and lifetimes with improved triplet quantum yields in comparison to the compounds. Accordingly, the AgNPs and AuNPs conjugates with the compounds afforded high singlet quantum yields. On the contrary, the conjugates of the alloy afforded decreased singlet quantum yields probably due to the screening effect. The compounds and their conjugates with NPs could serve as a viable and efficacious photosensitizer for photodynamic therapy. (C) 2017 Elsevier B.V. All rights reserved.

Using near-infrared (NIR) spectroscopy, we aimed to develop a method of monitoring the increasing number of amide bonds with the elongation of the chain length of peptides. Because peptide synthesis can be monitored by evaluating the increasing number of amide bonds with dehydration occurring between amino acids, polyglycine, which has the simplest structure among polyamino acids, was studied, and the key bands whose absorption intensities increased with the elongation of the chain length, such as the bands attributed to glycine, diglycine, triglycine, and tetraglycine, were searched. The bands due to the combinations of the amide A and amide II/III modes in the region of 5000-4500 cm(-1) were revealed to be good candidates for key bands, their second derivative intensities increased as the number of amide bonds increased, regardless of pH, solvent species, and the presence of protecting groups. The number of amide bonds was evaluated by a partial least square regression using the abovementioned combination bands, and a calibration model with a high determination coefficient (>0.99) was constructed. These results not only have demonstrated the usefulness of NIR spectroscopy as a process analytical technology tool for the process of synthesizing the peptide in a microflow reactor but also have provided basic knowledge for analyzing amide bonds in the NIR spectra of proteins, polyamino acids, polypeptides, and polyamides.

Alzheimer’s disease (AD), a common chronic neurodegenerative disease, has become a major public health concern. Despite years of research, therapeutics for AD are limited. Overexpression of secretory glutaminyl cyclase (sQC) in AD brain leads to the formation of a highly neurotoxic pyroglutamate variant of amyloid beta, pGluAp, which acts as a potential seed for the aggregation of full length A beta. Preventing the formation of pGlu-A beta through inhibition of sQC has become an attractive disease-modifying therapy in AD. In this current study, through a pharmacophore assisted high throughput virtual screening, we report a novel sQC inhibitor (Cpd-41) with a piperidine-4-carboxamide moiety (IC50 = 34 mu M). Systematic molecular docking, MD simulations and X-ray crystallographic analysis provided atomistic details of the binding of Cpd-41 in the active site of sQC. The unique mode of binding and moderate toxicity of Cpd-41 make this molecule an attractive candidate for designing high affinity sQC inhibitors. (C) 2020 Elsevier B.V. All rights reserved.

Copper(II) complexes of five peptide ligands containing at least three histidine residues have been tested as catalysts in catechol oxidation and superoxide dismutation. All systems exhibit considerable catechol oxidase-like activity, and the Michaelis-Menten enzyme kinetic model is applicable in all cases. Beside the Michaelis-Menten parameters, the effects of pH, catalyst and dioxygen concentration on the reaction rates are also reported. Considering the rather different sequences, the observed oxidase activity seems to be a general behavior of copper(II) complexes with multihistidine peptides. Interestingly, in all cases {N-im/2N(im),2N(-)} coordinated complexes are the pre-active species, the bound amide nitrogens were proposed to be an acid/base site for facilitating substrate binding. The studied copper(II)-peptide complexes are also able to effectively dismutate superoxide radical in the neutral pH range.

To reveal insights into the inhibition of BCR-ABL and its mutants, structure-based computing methods, such as docking, molecular dynamics (MD) simulation, the molecular mechanics generalized born surface area (MMGBSA), and biological characterizations, were employed to analyze two main pharmacophore zones and two related regions of imatinib derivatives. The hydrophobic and halogen interactions formed by the trifluoromethyl, as well as T-shaped p-p interactions formed by the pyrimidine, were confirmed. For the imatinib derivatives, the impacts of the amide moiety (region A) and the pyridine (region B) on the formed interactions were explored. To reveal insights into the inhibition of BCR-ABL mutants, the bioactivities of imatinib, nilotinib and flumatinib against BCR-ABL mutants were evaluated, and a point mutant (Y253F) of BCR-ABL was simulated. The results of our structure-based analysis and biological characterization of imatinib derivatives towards the inhibition of wild-type BCR-ABL and its mutants may provide new ideas for the design of imatinib analogs with potent activity.
