Structure-Activity Study of an All-D Antimicrobial Octapeptide D2D

The increasing emergence of multi-drug resistant bacteria is a serious threat to public health worldwide. Antimicrobial peptides have attracted attention as potential antibiotics since they are present in all multicellular organisms and act as a first line of defence against invading pathogens. We have previously identified a small all-D antimicrobial octapeptide amide kk(1-nal)fk(1-nal)k(nle)-NH2 (D2D) with promising antimicrobial activity. In this work, we have performed a structure-activity relationship study of D2D based on 36 analogues aimed at discovering which elements are important for antimicrobial activity and toxicity. These modifications include an alanine scan, probing variation of hydrophobicity at lys(5) and lys(7), manipulation of amphipathicity, N-and C-termini deletions and lys-arg substitutions. We found that the hydrophobic residues in position 3 (1-nal), 4 (phe), 6 (1-nal) and 8 (nle) are important for antimicrobial activity and to a lesser extent cationic lysine residues in position 1, 2, 5 and 7. Our best analogue 5, showed MICs of 4 mu g/mL against A. baumannii, E. coli, P. aeruginosa and S. aureus with a hemolytic activity of 47% against red blood cells. Furthermore, compound 5 kills bacteria in a concentration-dependent manner as shown by time-kill kinetics. Circular dichroism (CD) spectra of D2D and compounds 1-8 showed that they likely fold into alpha-helical secondary structure. Small angle x-ray scattering (SAXS) experiments showed that a random unstructured polymer-like chains model could explain D2D and compounds 1, 3, 4, 6 and 8. Solution structure of compound 5 can be described with a nanotube structure model, compound 7 can be described with a filament-like structure model, while compound 2 can be described with both models. Lipid interaction probed by small angle X-ray scattering (SAXS) showed that a higher amount of compound 5 (similar to 50-60%) inserts into the bilayer compared to D2D (similar to 30-50%). D2D still remains the lead compound, however compound 5 is an interesting antimicrobial peptide for further investigations due to its nanotube structure and minor improvement to antimicrobial activity compared to D2D.

Tissue Distribution, Accumulation, and Metabolism of Chiral Flufiprole in Loach (Misgurnus anguillicaudatus)

Flufiprole is an insecticide used in the rice field and may pose a potential threat to aquatic organisms including loach. To investigate the transformation products of flufiprole in loach, the accumulation, elimination, and tissue distribution in vivo as well as the metabolism in vitro at the enantiomeric level were studied. Flufiprole enantiomers rapidly accumulated and were metabolized to flufiprole sulfone, fipronil, and flufiprole amide in the tissues. Enantiomeric fractions showed the preferential accumulation and degradation of S-flufiprole. The residue of the chiral metabolite flufiprole amide was also enantioselective. The individual enantiomer treatment indicated that S-flufiprole was preferentially metabolized to flufiprole sulfone and R-flufiprole to fipronil. The metabolites were more persistent than flufiprole with longer half-lives. The metabolism in liver microsomes also reached consistent conclusions. The dietary risk assessment indicated that flufiprole would not cause unacceptable threats to human health. However, the metabolites of flufiprole should be considered in the risk evaluation.

Synergistic solvent extraction of lanthanide ions with mixtures of D2EHPA and MIDPA in phosphonium-based ionic liquids

In this study, the synergistic solvent extraction of lanthanide(III) with mixtures of di-(2-ethylhexyl)phosphoric acid (D2EHPA, H(2)A(2)) and monoisodecyl phosphoric acid (MIDPA, H2B2) in phosphonium-based ionic liquid was investigated from amide acid medium. The method of slope analysis was used for the determination of the extraction reaction. In the case of D2EHPA or MIDPA single extractant system, Ln(III) (Ln = Pr and Nd) was extracted as [LnA(3)HA] or [LnB(3)HB], respectively. Tb(III) or Dy(III) were extracted as [TbH(2)A(2)B(2)(NTf2)] or [DyH(2)A(2)B(2)(NTf2)] instead of [TbA(3)HA(NTf2)] or [DyA(3)HA(NTf2)] for D2EHPA and MIDPA synergistic system. According to the equilibrium constants (kappa(A), kappa(B) and kappa(AB)) and the formation constants (8 1 ,h and ,8 3 ), it was found that the extracted complex [TbHA(2)B(2) ] or [DyHA(2)B(2)] was more stable than [LnA(3)HA] or [LnB(3)HB] due to the synergistic effect of D2EHPA and MIDPA. The thermodynamic functions (OH, AG, and AS) were estimated from the temperature dependence of the synergistic extraction system. The result indicated that the synergistic extraction reaction was endothermically driven for this extraction system. Furthermore, the synergistic extraction effects were investigated to study the possibility of separating Dy(III) from Pr(III) and Nd(III) according to their separation factors.

Synthesis, characterization, in vitro biological and molecular docking evaluation of N,N’-(ethane-1,2-diyl)bis(benzamides)

The present research describes the synthesis, characterization, in vitro biological and docking evaluation of N,N’-(ethane-1,2-diyl)bis(benzamides) (3a-3j). Consequently, in in vitro hRBCs hemolysis assay, only the bis-amide (3d) induced 52.4% hemolysis at higher concentration (1000 mu g/mL) that decreased drastically with concentration (250 mu g/mL) to 27.9% (CC50 = 400.41). Similarly, the tested bis-amide (3j) was found to be the least toxic with 7.8% hemolysis at higher concentration (1000 mu g/mL) that gradually decreases to 6.1% (CC50 = 19,347.83) at lower concentration (250 mu g/mL). Accordingly, the tested bis-amides were found to be highly biocompatible against hRBCs at higher concentrations with much higher CC50 values (> 1000 mu g/mL). The biocompatible bis-amides (3a-3j) were subjected to in vitro DNA ladder assay to analyze their apoptotic potential. The results obtained suggest the tested bis-amides (3a-3j) are highly degradative toward DNA causing the appearance of more than one bands or complete degradation of DNA except (3a), (3c), (3i) and (3 g). Moreover, the synthesized bis-amides (3a-3j) were tested in in vitro antileishmanial assay to unveil their leishmaniacidal potential. The results obtained clearly indicated that some of the tested bis-amides displayed good dose dependent response. The tested bis-amides were highly active at higher concentration (1000 mu g/mL) against the leishmanial promastigotes and their % inhibitory potential decreased drastically with concentration (250 mu g/mL). Consequently, at higher concentration (1000 mu g/mL), the bis-amide (3f) caused 85% inhibition and was ranked as the most effective leishmaniacidal bis-amides followed by the bis-amide (3 g) with 73.54% inhibition of leishmanial promastigotes. However, in terms of their IC50 values, the best leishmaniacidal potential was displayed by the bis-amide (3f) followed by (3b), (3j) and (3 g) with IC50 values increasing in the order of 633.16, 680.22, 680.22 and 712.93 mu g/mL, respectively. Molecular docking studies revealed that bis-amides having electron-donating groups showed good binding potential against antileishmanial target. [GRAPHICS] .

The Placebo Effect in Cardiology: Understanding and Using It

The placebo effect is the clinical benefit caused by interaction with a caregiver and health care system in the absence of a biologically active intervention and has been used successfully for millennia. The placebo response results from the interaction of psychosocial mechanisms, human relationships, and preconceptions functioning in specific neuroan-atomic locations with known genes and neurotransmitters. It occurs with or without the administration of an inactive substance to deliberately deceive patients. Our purpose is to review the history, benefits, and mechanisms of the placebo effect. The placebo response results from classic conditioning and positive expectations about outcome expressed by the caregiver. The outcomes are usually symptoms such as pain rather than biological outcomes such as death, and the powerful placebo may account for more than half the effect of treatment in many situations. The placebo effect results from activation of opioid, cannabinoid, and dopaminergic pathways involved in reward, expectancy, conditioning, and pain modulation. Eleven specific anatomic features in the brain identified by positron emission tomography and magnetic resonance imaging are involved. Polymorphisms in the structural genes for catecholamine O-methyltransferase and fatty acid amide oxidase significantly influence the placebo response. The placebo effect may be important in symptom suppression in angina, paroxysmal atrial fibrillation, and congestive heart failure. In the absence of deliberate deception, there are no ethical issues and given its potency, the time has come to consider how best to use the placebo in clinical practice.

Spectroscopy of N,N-dimethylformamide in the VUV and IR regions: Experimental and computational studies

The electronic absorption spectrum of N, N-dimethylformamide (DMF) is studied in the 45 000 -80 000 cm(-1) (5.6-9.9 eV) region using synchrotron radiation. The vacuum ultraviolet (VUV) spectrum comprises mostly of Rydberg series of ns, np, and nd types converging to the first two ionization potentials (IPs). Quantum defect values obtained are consistent with excitation of an electron from the highest occupied molecular orbitals localized on nitrogen (4a) and oxygen (16a’); in addition, the 3s Rydberg transition converging to the third IP (3a) is observed at 8.95 eV. A reinvestigation of the infrared spectrum of DMF in the 500-4000 cm(-1) region with the help of density functional theory (DFT) calculations establishes the planarity of the ground state and leads to revision of several vibrational assignments. Vertical excited state energies and their valence/Rydberg character are predicted using time dependent DFT calculations; excellent correlation is achieved between theoretical results and experimentally observed spectral features. Potential energy curves of the first few excited states give additional insights into the nature of the excited states and their role in photodissociation dynamics. The absorption spectrum of DMF in the region > 63 400 cm(-1) (7.85 eV) as well as a complete set of spectral assignments in the VUV region (45 000-80 000 cm(-1)) is reported for the first time. This work represents a comprehensive study of the absorption spectra of DMF in the VUV and infrared regions. Published by AIP Publishing.

Chlorine-resistant TFN RO membranes containing modified poly (amidoamine) dendrimer-functionalized halloysite nanotubes

Incorporation of additional amines into polyamide-based reverse osmosis (RO) membranes has been suggested as a strategy to increase the chlorine resistance of such membranes. In this work, we investigate the effects of the poly(amidoamine) PAMAM dendrimers of different generations on the separation performance and chlorine resistance of thin-film nanocomposite (TFN) membranes. Three generations of PAMAM dendrimers were grafted on halloysite nanotubes (HNTs) and incorporated into the reverse osmosis (RO) membranes synthesized by interfacial polymerization of m-phenylenediamine (MPD) and trimesoyl chloride (TMC). ATR-FTIR, SEM, XPS, TGA, and surface contact angle analyses were used to characterize the physicochemical properties of the nanoparticles and membranes. Membranes’ separation performance was tested in a cross-flow RO system with synthetic brackish water. Compared to thin-film composite (TFC) membranes, TFN membranes showed a twofold increase in water flux with a slight decrease in NaCl rejection. In addition, passive chlorination tests showed that the overall effects of chlorination on membrane performance varied based on the generation of the PAMAM dendrimers. After 12,000 ppm.h chlorine exposure, a decrease in salt rejection with an increase in the water flux of the control TFC membrane was observed. In contrast, membranes with the second and third generations of PAMAM dendrimers (TFN-HNT-G2 & G3) displayed enhanced membrane stability with no statistically significant alteration in their salt rejection after chlorination. TFN-HNT-G2 had the optimum overall desalination performance after chlorination with similar to 85.6% water flux improvement while maintaining its average salt rejection of 96.6%. The enhanced chlorination resistance of these membranes was attributed to the scavenger role of the extra amine and amide groups from the PAMAM functionalized HNTs.

Rationalizing the diversity of amide-amide H-bonding in peptides using the natural bond orbital method

Natural bond orbital (NBO) analysis of electron delocalization in a series of capped isolated peptides is used to diagnose amide-amide H-bonding and backbone-induced hyperconjugative interactions, and to rationalize their spectral effects. The sum of the stabilization energies corresponding to the interactions between NBOs that are involved in the H-bonding is demonstrated as an insightful indicator for the H-bond strength. It is then used to decouple the effect of the H-bond distance from that, intrinsic, of the donor/acceptor relative orientation, i.e., the geometrical approach. The diversity of the approaches given by the series of peptides studied enables us to illustrate the crucial importance of the approach when the acceptor is a carbonyl group, and emphasizes that efficient approaches can be achieved despite not matching the usual picture of a proton donor directly facing a lone pair of the proton acceptor, i.e., that encountered in intermolecular H-bonds. The study also illustrates the role of backbone flexibility, partly controlled by backbone-amide hyperconjugative interactions, in influencing the equilibrium structures, in particular by frustrating or enhancing the HB for a given geometrical approach. Finally, the presently used NBO-based HB strength indicator enables a fair prediction of the frequency of the proton donor amide NH stretching mode, but this simple picture is blurred by ubiquitous hyperconjugative effects between the backbone and amide groups, whose magnitude can be comparable to that of the weakest H-bonds.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 609-36-9 is helpful to your research. Quality Control of H-DL-Pro-OH.
