Rodrigues, Carina Alexandra;Zomer, Ana Paula Lourencao;Rotta, Eliza Mariane;Visentainer, Jesui Vergilio;Maldaner, Liane research published 《 A μ-QuEChERS method combined with UHPLC-MS/MS for the analysis of phenolic compounds in red pepper varieties》, the research content is summarized as follows. In this study, a method based on QuEChERS method miniaturization followed by UHPLC-MS/MS anal. was used for the first time to determine phenolic acids and flavonoids in red pepper (Capsicum spp.). Under the optimized extraction and anal. conditions, fourteen phenolic compounds in eleven varieties of red pepper belonging to four domesticated species, C. baccatum L., C. chinense Jacq., C. frutescens L., and C. annuum L., were evaluated. 4-Hydroxybenzoic, p-coumaric, vanillic and ferulic acids, and naringenin were the phenolic compounds found in all varieties evaluated. Among them, vanillic and ferulic acids and naringenin were found in higher amounts, accounting for 92.2% of the total phenolic compounds quantified in all varieties evaluated. Overall, this study reveals relevant and innovative data about the composition of the phenolic compounds of red peppers, especially for those varieties little or not yet studied, such as “Cambuci,” “Dedo-de-moca,” “Big Red Mama,” “Brazilian Moruga,” “Biquinho,” “Naga Morich,””Fatalii Gourmet Jigsaw,” and “Bhut Jolokia Assam”, which will boost its potential uses in agro-food, cosmetic and pharma industry, as well as in health promotion. Furthermore, data support that the μ-QuEChERS method was more cost-effective, less time-consuming, and environmentally friendly, constituting a promising trend for phenolic compounds determination in plant matrixes.

Rober, Matthias;Scheibel, Thomas;Borner, Hans G. research published 《 Toward Activatable Collagen Mimics: Combining DEPSI “Switch” Defects and Template-Guided Self-Organization to Control Collagen Mimetic Peptides》, the research content is summarized as follows. Collagen mimetic peptides (CMPs), which imitate various structural or functional features of natural collagen, constitute advanced models illuminating the folding aspects of the collagen triple helix (CTH) motif. In this study, the CMPs of repeating Gly-Pro-Pro (GPP) triplets are tethered to an organic scaffold based on a tris(2-aminoethyl) amine (TREN) derivative (TREN(sucOH)₃). These three templated peptide strands are further expanded via native chem. ligation to increase the number of GPP triplets and lead to a TREN(sucGPPGPPG(Ψ)SPGPPCPP[GPP]₄)₃ construct. The incorporation of an ester switch segment, G(Ψ)S, as a positional O-acyl isopeptide (DEPSI) defect into the peptide strands allows the pH-controlled acceleration of CTH formation. The strand assembly process is monitored by CD (CD) spectroscopy. The results of pH jump experiments and thermal denaturation studies provide new insights into the contributions of structural DEPSI defects to the template-guided self-assembly of the CTH motif. While the organic scaffold drives the CTH formation, the switch defects act as temporary opponents and slow down the folding. CD spectroscopy data confirm that the switch defects contribute to the formation of a more stable CTH motif by enhancing the structural dynamics at the early stage of the folding process.

Richard-Bildstein, Sylvia;Aissaoui, Hamed;Pothier, Julien;Schafer, Gabriel;Gnerre, Carmela;Lindenberg, Eleanor;Lehembre, Francois;Pouzol, Laetitia;Guerry, Philippe research published 《 Discovery of the Potent, Selective, Orally Available CXCR7 Antagonist ACT-1004-1239》, the research content is summarized as follows. The chemokine receptor CXCR7, also known as ACKR3, is a seven-transmembrane G-protein-coupled receptor (GPCR) involved in various pathologies such as neurol. diseases, autoimmune diseases, and cancers. By binding and scavenging the chemokines CXCL11 and CXCL12, CXCR7 regulates their extracellular levels. From an original high-throughput screening campaign emerged an arylketoamide hit among others. The hit-to-lead optimization led to the discovery of a novel chemotype series of acylaminopiperidinecarboxamides. This series provided CXCR7 antagonists that block CXCL11- and CXCL12-induced ss-arrestin recruitment. Further structural modifications on the acylaminopiperidinecarboxamide framework yielded compounds with high CXCR7 antagonistic activities and balanced ADMET properties. The effort described herein culminated in the discovery of ACT-1004-1239 I. Biol. characterization of I demonstrated that it is a potent, insurmountable antagonist. Oral administration of I in mice up to 100 mg/kg led to a dose-dependent increase of plasma CXCL12 concentration

An isocratic RP-HPLC was developed and validated for isolation of 1′-Acetoxychavicol acetate (ACA) from Alpinia galanga extract (AGE). Nucleodur C18 column was used as the stationary phase and mixture of acetonitrile/0.1% formic acid in water (60/40, volume/volume) were used as mobile phase. The elution was carried out with a flow rate of 1 mL/min. Further, the method was validated as per ICH Q2 [R1] guidelines in terms of linearity, LOD, LOQ, recovery, precision and specificity. The validated method was utilized for two purposes i.e. optimizing the isolation of ACA from AGE and quantifying ACA′s concentration and release from its nanoemulsion. To achieve high yield of ACA, Central composite design (CCD) was used to optimize sieve number and solid to solvent ratio. The retention time of standard and isolated ACA were found at 5.63 min and 5.46 min resp. The results indicated that the validated method was linear, accurate, precise and specific. During optimization, excellent correlation was observed between practical yield (3.89 ± 0.23% weight/weight of dried rhizomes) and predicted yield (3.73% weight/weight of dried rhizomes) of ACA with p value more than 0.05. The percentage of ACA loaded in the nanoemulsion was found to be 99.12 ± 0.39. The in vitro diffusion studies showed 90.12 ± 2.21% release of ACA at the end of 24 h. It was concluded that the validated method has been successfully utilized to isolate the ACA from AGE and quantify the amount of ACA present in nanoemulsion.
