The aims of this study are to isolate and characterize acid soluble collagen (ASC) and pepsin soluble collagen (PSC) extracted from silver catfish (Pangasius sp.) skin. Isolated ASC and PSC collagen were characterized in terms of chemical composition (moisture, protein, fat and ash content), protein concentration, functional group, solubility, and morphological properties as compared to commercial collagen. Yields of ASC and PSC were 4.27% and 2.27%, respectively. The chemical compositions of raw skin were 34.64%, 2.81%, 3.68%, and 0.31%, while the chemical compositions of ASC and PSC were 94.21%, 3.48%, 0.81%, 59.15%, and 88.25%, 3.46%, 0.92%, and 29.24%, for moisture, protein, fat, and ash, respectively. ASC and PSC had protein concentrations of 2.27 mg/mL and 2.70 mg/mL, respectively. Functional group analysis revealed that both isolated collagens exhibited Amide A, II and III as a fingerprint for collagen structure. The highest solubility was found at pH 4 for ASC, pH 1 for PSC, and pH 5 for commercial collagen. The morphology of the isolated collagens was porous and they contained fibril. In conclusion, the characteristics of the isolated ASC and PSC from silver catfish (Pangasius sp.) skin indicate that value-added collagen can be produced from the alternative source of freshwater fish.

The metal-catalyzed dehydrogenative coupling of alcohols and amines to access amides has been recognized as an atom-economic and environmental-friendly process. Apart from the formation of the amide products, three other kinds of compounds (esters, imines and amines) may also be produced. Therefore, it is of vital importance to investigate product distribution in this transformation. Herein, N-heterocyclic carbene-based Ru (NHC/Ru) complexes [Ru-1]-[Ru-5] with different ancillary ligands were prepared and characterized. Based on these complexes, we selected condition A (without an added NHC precursor) and condition B (with an added NHC precursor) to comprehensively explore the selectivity and yield of the desired amides. After careful evaluation of various parameters, the Ru loadings, added NHC precursors and the electronic/steric properties of ancillary NHC ligands were found to have considerable influence on this catalytic process.

Since the first report by Evans in asymmetric Friedel-Crafts reactions, the use of acyl-imidazoles has blossomed as powerful ester/amide surrogates. The imidazole scaffold indeed displays stability and special activation features allowing both better reactivity and selectivity in traditional ester/amide functionalizations: alpha-(enolate chemistry), beta-(conjugate additions), alpha,beta-(cycloadditions) or gamma/delta-(vinylogous). An overview of the contemporary and growing interest in acyl-imidazoles in metal- and organo-catalyzed transformations (bio-hybrid catalytic systems will be fully described in a back-to-back Minireview) will be highlighted. Moreover, post-functionalization expediencies are also going to be discussed in this Minireview.

Programmed Nanococktail Based on pH-Responsive Function Switch for Self-Synergistic Tumor-Targeting Therapy

Tumor-targeting combination chemotherapy is an important way to improve the therapeutic index and reduce the side effects as compared to traditional cancer treatments. However, one of the major challenges in surface functionalization of nanoparticle (NP) is accomplishing multiple purposes through one single ligand. Upon such consideration, methotrexate (MTX), an anticancer drug with a targeting moiety inspired by the similar structure of folate, could be used to covalently link with lipid-polymer conjugate (DSPE-PEG) via a pH-sensitive dynamic covalent imine (CH=N) bond to synthesize the acid-induced function targeting-anticancer switching DSPE-PEG-CH=N-MTX. We hypothesize that using this kind of MTX prodrug to functionalize NP’s surface would be conductive to combine the early phase active targeting function and the late-phase anticancer function in one nanosystem. Herein, a nanococktail is programmed for codelivery of epirubicin (EPI) and MTX by co-self-assembly of acid-dissociated EPI-phospholipid (PC) complex and acid-cleavable DSPE-PEG-CH=N-MTX conjugate. The obtained nanococktail (MTX-PEG-EPI-PC NPs) could not only actively target folate receptors-overexpressing tumor cells but also respond to acidic endo/lysosomes for triggering the on-demand release of pharmaceutically active EPI/MTX. The intracellular drug distribution also demonstrated that the system could codeliver two drugs to individual target sites of action, inducing the significant synergistic anticancer efficiency based on different anticancer mechanisms. More importantly, the in vivo tumor accumulation and anticancer efficacy of MTX-PEG-EPI-PC NPs (via cleavable imine bond) were significantly enhanced as compared to the individual free drug, both free drugs, PEG-EPI-PC NPs, and MTX-PEG-EPI-PC NPs (via the uncleavable amide bond). This self-synergistic tumor-targeting therapy might represent a promising strategy for cancer treatment.

Backbone and ILVM methyl resonance assignments of human thymidylate synthase in apo and substrate bound forms

Human thymidylate synthase (hTS) is a 72 kDa homodimeric enzyme responsible for the conversion of deoxyuridine monophosphate (dUMP) to deoxythymidine monophosphate (dTMP), making it the sole source of de novo dTMP in human cells. As a result, hTS is an attractive anti-cancer therapeutic target. Additionally, hTS is known to possess a number of interesting biophysical features, including adoption of active and inactive conformations, positively cooperative substrate binding, half-the-sites activity, and interacting with its own mRNA. The physical mechanisms underlying these properties, and how they may be leveraged to guide therapeutic development, are yet to be fully explored. Here, as a preface to detailed NMR characterization, we present backbone amide and ILVM methyl resonance assignments for hTS in apo and dUMP bound forms. In addition, we present backbone amide resonance assignments for hTS bound to a substrate analog and the native cofactor.
