Methods: We recruited 66 men aged 65-80 years. The 3-day frequency volume chart (FCV), International Prostate Symptom Score (IPSS), and quality of life score were used to assess micturition behavior. Participants with the total IPSS > 0 and ≥ 1.5 micturition on an average for three nights were included in the nocturia group. Participants with the total IPSS < 8 and < 1.5 micturition at night were included in the control group. Metabolites were compared between the groups using an unpaired t test. Results: The nocturia and control groups consisted of 45 and 21 men, resp. There were no differences in the background factors between the groups except for receiving anticholinergic drug and having life style-related diseases. The FVC revealed that nocturnal urine volume, 24 h micturition frequency, and nocturnal micturition frequency were significantly higher in the nocturia group than in the control group. The metabolomic anal. revealed 16 metabolites, which were differentially expressed between the groups. The multivariate anal. showed that increased serotonin level and decreased 3-hydroxypropionic acid and 3-indoleacetonitrile levels were associated with nocturia. Conclusions: These findings suggest that abnormal urinary metabolites including serotonin, 3-hydroxypropionic acid, and 3-indoleacetonitrile are involved in the pathogenesis of nocturia in elderly men.

Kim, Yong-Guy;Lee, Jin-Hyung;Park, Sunyoung;Lee, Jintae research published 《 The anticancer agent 3,3′-diindolylmethane inhibits multispecies biofilm formation by acne-causing bacteria and Candida albicans》, the research content is summarized as follows. The Gram-pos. anaerobic bacterium Cutibacterium acnes is a major inhabitant of human skin and has been implicated in acne vulgaris formation and in the formation of multispecies biofilms with other skin-inhabiting organisms like Staphylococcus aureus and Candida albicans. Indoles are widespread in nature (even in human skin) and function as important signaling mols. in diverse prokaryotes and eukaryotes. In the present study, we investigated the antibacterial and antibiofilm activities of 20 indoles against C. acnes. Of the indoles tested, indole-3-carbinol at 0.1 mM significantly inhibited biofilm formation by C. acnes without affecting planktonic cell growth, and the anticancer drug 3,3′-diindolylmethane (DIM) at 0.1 mM (32μg/mL) also significantly inhibited planktonic cell growth and biofilm formation by C. acnes, whereas the other indoles and indole itself were less effective. Also, DIM at 0.1 mM successfully inhibited multispecies biofilm formation by C. acnes, S. aureus, and C. albicans. Transcriptional analyses showed that DIM inhibited the expressions of several biofilm-related genes in C. acnes, and at 0.05 mM, DIM inhibited hyphal formation and cell aggregation by C. albicans. These results suggest that DIM and other indoles inhibit biofilm formation by C. acnes and have potential use for treating C. acnes associated diseases.

Kim, Kyunghee;Kloxin, Christopher J.;Saven, Jeffery G.;Pochan, Darrin J. research published 《 Nanofibers produced by electrospinning of ultrarigid polymer rods made from designed peptide bundlemers》, the research content is summarized as follows. Mimicking the hierarchical assembly of natural fiber materials is an important design challenge in the manufacturing of nanostructured materials with biomols. such as peptides. Here, we produce nanofibers with control of structure over multiple length scales, ranging from peptide mol. assembly into supramol. building blocks called “bundlemers,” to rigid-rod formation through a covalent connection of bundlemer building blocks, and, ultimately, to uniaxially oriented fibers made with the rigid-rod polymers. The peptides are designed to phys. assemble into coiled-coil bundles, or bundlemers, and to covalently interact in an end-to-end fashion to produce the rigid-rod polymer. The resultant rodlike polymer exhibits a rigid, cylindrical nanostructure confirmed by transmission electron microscopy (TEM) and, correspondingly, exhibits shear-thinning behavior at low shear rates observed in many nanoscopic rod systems. The rigid-rod chains are further organized into final fiber materials via electrospinning processing, all the while preserving their unique rodlike structural characteristics. Morphol. and structural investigations of the nanofibers through SEM, transmission electron microscopy, and X-ray scattering, as well as mol. characterization via Fourier transform IR (FTIR) and Raman spectroscopy, show that continuous nanofibers are composed of oriented rigid-rod chains constituted by α-helical peptides within bundle building blocks. Mech. properties of electrospun fibers are also presented. The ability to produce nanofibers from the oriented rigid-rod polymer reveals bundlemer chains as a viable tool for the development of new fiber materials with targeted structure and properties.

Kim, Dong-in;Han, Seong-jae;Lim, Yong-beom research published 《 Unique behavior of the α-helix in bending deformation》, the research content is summarized as follows. The maximum degree of bending that can be tolerated by the rigid rod-like α-helix remains unknown; however, it should be very difficult or even impossible to make α-helixes with varying degrees of curvature in folded proteins. As an exptl. tractable model, here we utilize cyclic proteins and peptides to determine the maximum possible bending in the α-helix. We artificially enforced bending in the α-helixes by using variously sized macrocycles and compared the structural characteristics of the macrocycles with those of their linear counterparts. This differential anal. reveals that the radius of curvature (RC) for the maximally bent α-helix is approx. 10 times smaller than those of typical α-helixes found in natural proteins. Together with the novel finding of the limit of α-helix deformation, excessively bent α-helixes can be further utilized in designing de novo peptides and proteins with unique structures and peculiar functions.

Keutgen, N.;Tomaszewska-Sowa, M.;Keutgen, A. J. research published 《 Chlorophyll fluorescence of Nicotiana tabacum expressing the green fluorescent protein》, the research content is summarized as follows. Evidence that the green fluorescence protein (GFP) develops a significant toxicity in plants has not been found, but it may represent a source of free radicals as a consequence of its fluorescence. In addition green light is known to trigger the acclimatisation of the photosynthetic system towards a shady environment. Moreover, the light-harvesting system may acclimate to an increased availability of green light. Each of these effects may be induced by the GFP. Therefore, the hypothesis was tested, whether transformation of Nicotiana tabacum cv. Bursan to express the GFP could affect chlorophyll fluorescence parameters. The anal. revealed a significantly lower absorption of energy per excited cross section in GFP-transformed tobacco, a lower number of active reaction centers per excited cross section, a larger absorption and trapped energy flux leading to the reduction of the primary quinone electron acceptor of PSII per reaction center, and a lower variable fluorescence.

Appropriate synthesis methods gave six different indole derivatives substituted at the C-2 or C-3 position. ESIPT emission capacities of these derivatives were investigated. It was concluded that the indole derivative containing the 1,2-dicarbonyl group at the C-2 position has ESIPT emission. Although adding water to the DMSO solution of the ESIPT-based mol.

TD-DFT calculation for uncovering the ESIPT mechanism emerged that the ESIPT mechanism occurred as a barrierless process. The X-ray anal. and DFT conformational anal. revealed that NH and CO groups involving proton transfer mechanisms are in the cis position. A mono-exponential decay was observed in DMSO and MeOH solutions, in which lifetimes were measured as 6.1 and 5.5 ns, resp. pH studies revealed that acidic and basic solutions of mol. 7 did not influence ESIPT emission.

Kanta Mahato, Rajani;Kumar Mudi, Prafullya;Deb, Mayukh;Biswas, Bhaskar research published 《 A Direct metal-free synthetic approach for the efficient production of privileged benzimidazoles in water medium under aerobic condition》, the research content is summarized as follows. A metal-free methodol. for the synthesis of 1,2-disubstituted and 2-substituted benzimidazoles with high to excellent yields was developed. The course of synthesis involved easy work-up, straightforward purification, inexpensive reaction setup and wide substrate scope under extremely mild and operationally simple conditions which makes the synthetic strategy more lucrative, practical and reliable. The serious challenge to carry out these reactions in a pure aqueous medium was achieved at 75°C in presence of air bubbles. The applicability of this operationally simple and metal-free synthetic approach for the gram-scale synthesis of benzimidazole derivatives with good yield (∼74%) further strengthens its potentiality for the synthesis at an industrial scale.

Kang, Hee Kyoung;Park, Jonggwan;Seo, Chang Ho;Park, Yoonkyung research published 《 PEP27-2, a Potent Antimicrobial Cell-Penetrating Peptide, Reduces Skin Abscess Formation during Staphylococcus aureus Infections in Mouse When Used in Combination with Antibiotics》, the research content is summarized as follows. PEP27, a 27-amino acid (aa) peptide secreted by Streptococcus pneumoniae, is an autolytic peptide that functions as a major virulence factor. To develop a clin. applicable antimicrobial peptide (AMP), we designed PEP27 analogs with Trp substitutions to enhance its antimicrobial activity compared to that of PEP27. Particularly, PEP27-2 showed strong antimicrobial activity against a wide variety of bacteria, including multidrug-resistant (MDR) bacteria. It was found that the antimicrobial activity of PEP27-2 was increased by substituting Trp for the aa at the middle position of PEP27. We found that PEP27-2 acts as an effective cell-penetrating peptide in bacterial and mammalian cells. Here, we proved that s.c. infection with MDR Staphylococcus aureus induced skin lesions such as skeletal muscle damage, deep inflammation, and necrosis of the overlaying dermis in mice. Combination treatment with antibiotics revealed synergistic effects, remarkably reducing abscess size and improving the bacteria removal rate from the infection site. Moreover, PEP27-2-antibiotic combination treatment reduced inflammation, lowering levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, inducible NO synthase (iNOS), and cyclooxygenase (COX-2) in skin abscess tissue. The results suggest that the PEP27-2 peptide is a promising therapeutic option for combating MDR bacterial strains by enhancing antibiotic penetration and protecting against MDR bacteria.

35737-15-6, Nalpha-FMOC-L-Tryptophan,also known as Fmoc-Trp-OH， is a useful research compound. Its molecular formula is C26H22N2O4 and its molecular weight is 426.5 g/mol. The purity is usually 95%.
Nα-Fmoc-L-Tryptophan is an N-Fmoc protected form of L-Tryptophan (T947210). L-Tryptophan is an essential amino acid that is important for cell proliferation and the biosynthesis of proteins. It is a precursor to Serotonin (HCl: S274980), a neurotransmitter that compound that aids in sleep and mental state. L-Tryptophan is also thought to cause eosinophilia-myalgia syndrome.
Fmoc-Trp-OH is an amino acid derivative
Fmoc-L-Trp-OH is an amide that contains a low bioavailability and inhibits the transfer of amino acids to ribosomes. It has been shown to inhibit the growth of cancer cells in cell culture and to have antimicrobial activity. Fmoc-L-Trp-OH is synthesized by reacting Naphthalene with glycine, followed by hydrolysis of the ester group under trifluoroacetic acid. The product is then conjugated with a polypeptide. This method of synthesis was developed as a way to produce peptides that are difficult to synthesize using solid-phase chemistry., Reference of 35737-15-6
