Rhipicephalus (Boophilus) microplus is one of the most important ectoparasites in cattle breeding worldwide, causing direct and indirect losses to animals and producers. Chemical acaricides are utilized in the control of cattle tick and the increase in the development of resistance by ectoparasites makes new alternative necessary. Therefore, research studies have been carried out using bioactive molecules that are quickly degraded and that reduce poisoning to appliers and non-target organisms, environmental contamination and development of resistance. Thus, this study aimed to isolate piperovatine from the roots of Piper corcovadensis, a native species to Brazil, and to evaluate the larvicidal activity against Rhipicephalus (Boophilus) microplus by larval packet test and in ex situ in an open environment. Piperovatine was isolated by classical column chromatography, and identified by H-1 and C-13 NMR. The lethal concentration (LC) of piperovatine that killed 50% (LC50) and 99% (LC99) of the larvae was determined by Probit analysis. The results indicated LC50 5.17 and LC99 25.41 mu g/mL. LC99 was tested in ex situ in an open environment, and an efficiency of 96.63% was found, indicating that piperovatine kept the larvicidal action determined in in vitro test and in open environment. Therefore, this study shows new perspectives to develop products that can be applied in natural conditions to control this ectoparasite.

The asymmetric syntheses of a range of N- and O-protected 3-deoxy-3-aminosphingoid bases have been achieved using two complementary approaches. DL-Serine was converted to a racemic N,N-dibenzyl-protected gamma-amino-alpha,beta-unsaturated ester which was resolved using a parallel kinetic resolution (PKR) strategy upon reaction with a pseudoenantiomeric mixture of lithium (R)-N-benzyl-N-(alpha-methylbenzyl)amide and lithium (S)-N-3,4-dimethoxybenzyl-N-(alpha-methylbenzyl)amide, giving the corresponding enantio- and diastereoisomerically pure beta,gamma-diamino esters. Alternatively, elaboration of L-serine gave the corresponding enantiopure N,N-dibenzyl-protected gamma-amino-alpha,beta-unsaturated ester, and doubly diastereoselective conjugate addition of the antipodes of lithium N-benzyl-N-(alpha-methylbenzyl)amide was found to proceed under the dominant stereocontrol of the lithium amide reagent in both cases, thus augmenting the accessible range of beta,gamma-diamino esters. Both of these protocols were expanded to include in situ oxidation of the enolate formed upon conjugate addition, giving access to the corresponding alpha-hydroxy-beta,gamma-diamino esters. Elaboration of these beta,gamma-diamino and alpha-hydroxy-beta,gamma-diamino esters gave the protected forms of the 3-deoxy-3-aminosphingoid base targets.

Five new multicomponent solid forms of the biologically active 1,2,4-thiadiazole derivative (TDZH) with dicarboxylic and hydroxybenzoic acids have been discovered by combined virtual/experimental cocrystal screening. The interplay between the intrinsic hierarchy of the donor/acceptor groups in the TDZH/coformer molecules and the hydrogen bond pattern in the multicomponent crystals was rationalized using quantitative analysis of molecular electrostatic potential (MEP) surfaces along with periodic DFT computations. All the TDZH cocrystals are based on a carboxy-aminothiadiazole heterosynthon which is stabilized by a combination of enthalpic factors and the supramolecular chelating effect. According to the analysis of the non-covalent interaction energies, the mean energy value of this heterosynthon equals similar to 77 kJ mol(-1), which is comparable to the well-known carboxyl-amide and carboxyl-pyridine synthons in terms of the dissociation energy. The thermal stability of the multicomponent crystals was investigated by the DSC and TG methods. The pH-solubility behavior of the cocrystals was investigated at different pH values using eutectic concentrations of the components. Three out of five co-crystals were found to be more soluble than the parent TDZH at low pH values (approximate to 2.0). However, cocrystallization significantly alters the solubility-pH dependence of TDZH, increasing the compound solubility at neutral pH values.

The palladium-catalyzed Suzuki-Miyaura cross-coupling of N-acylsuccinimides as versatile acyl-transfer reagents via selective amide N-C bond cleavage is reported. The method is user-friendly since it employs commercially-available, air-stable reagents and catalysts. The cross-coupling is enabled by half-twist of the amide bond in N-acylsuccinimides. These highly effective, crystalline acyl-transfer reagents present major advantages over perpendicularly twisted N-acylglutarimides, including low price of the succinimide activating ring, selective metal insertion under redox neutral conditions and high stability of the amide bond towards reaction conditions. Mechanistic studies indicate that oxidative addition is the rate limiting step in this widely applicable protocol.

Polysaccharides have been used widely in many industries, from food technology and mining to cosmetics and biomedical applications. Over recent years there has been growing interest in the development of responsive polysaccharides with unique and switchable properties, particularly systems that display lower-critical solution temperatures (LCSTs). Therefore, in this study we aimed to investigate a novel strategy that would allow the conversion of non-responsive polysaccharides into thermoresponsive polysaccharides with tuneable LCSTs. Through the functionalisation of dextran with alkylamide groups (isopropyl amide, diethyl amide, piperidinyl and diisobutyl amide) using a carbodiimide coupling approach in conjunction with amic acid derivatives, we prepared a library of novel dextrans with various degrees of substitution (DS), which were characterised via nuclear magnetic resonance (NMR) spectroscopy and gel permeation chromatography (GPC). The alkylamide-functionalised dextrans were found to have good solubility in aqueous solutions, with the exception of those having a high DS of large hydrophobic substituents. Determination of the thermoresponsive characteristics of the polymer solutions via UV-vis spectroscopy revealed that the LCST of the alkylamide-functionalised dextrans was highly dependent on the type of alkylamide group and the DS and could be tuned over a large range (5-35 degrees C). Above the LCST, all of the thermoresponsive alkylamide-functionalised dextrans formed colloidal dispersions with particles sizes ranging from 400-600 nm, as determined by dynamic light scattering (DLS). In addition, the polymers were found to exhibit a fast and reversible phase transition in solution with narrow hysteresis (similar to 1-5 degrees C). Finally, the injectability and biocompatibility of the novel thermoresponsive dextrans was confirmed in vivo via subcutaneous and intracranial ventricle injections, with no local or systemic toxicity noted over a 14 d period. Overall, the alkylamide-functionalised dextrans display interesting thermoresponsive properties and trends that may make them useful in biomedical applications, such as drug-delivery.

The selective separation and extraction of lithium from salt lakes is compromised by the high salt concentration and the presence of competing ions. In this study, a class of novel cation exchange membranes based on Kevlar aramid nanofibers (KANFs) was designed via interpenetrating networks of poly(4-styrenesulfonic acid-co-maleic acid) sodium salt (PSSMA) and amide reaction of 4-amino-2,2,6,6-tetramethylpiperidine-1-oxyl (ATTO). Membranes with different PSSMA content were fabricated, and the final membrane denoted as A#PSSMA@KANF-2 achieved a similar to 1.2 mmol g(-1) ion exchange capacity, similar to 28% water content, similar to 4.5% swelling rate and similar to 1.8 Omega cm(2) surface electrical resistance. The thin A#PSSMA@KANF-2 membrane (similar to 8 mu m thickness) also exhibited a high membrane limiting current density of 32.0 mA cm(-2) (in 0.1 M NaCl solution) and an exceptional desalination efficiency (99.9% for NaCl) in electrodialysis. Moreover, compared to some commercial monovalent selectivity cation exchange membranes (CSO and CIMS membranes, which are two commercial monovalent cation selective membranes), the A#PSSMA@KANF-2 membrane was found functional for the separation of Li+/Mg2+ and to have an excellent anti-scaling performance. As the selectivity has potential to be as high or higher as that of commercial membranes, this work provides a promising method to develop membranes with anti-scaling performance for the extraction of lithium from high salt concentrations in salt lakes.

It has been established that a cyclopentadienyl (Cp) Rh-III complex with two aryl groups and a pendant amide moiety catalyzes the formal Lossen rearrangement/alkenylation cascade of N-pivaloyl heterole carboxamides with internal alkynes, leading to alkenylheteroles. Interestingly, the use of sterically demanding internal alkynes afforded not the alkenylation but the [3+2] annulation products ([5,5]-fused heteroles). In these reactions, the pendant amide moiety of the CpRhIII complex may accelerate the formal Lossen rearrangement. The use of five-membered heteroles may deter reductive elimination to form strained [5,5]-fused heteroles; instead, protonation proceeds to give the alkenylation products. Bulky alkyne substituents accelerate the reductive elimination to allow the formation of the [5,5]-fused heteroles.

Spilanthol is the most abundant pharmacologic agent present in Acmella oleracea, a popular Amazonian plant usually called as Jambu. We performed an experimental and theoretical investigation on several electronic properties connected to the molecular structure of spilanthol (S1) and the other two analogs (S2 and S3). Our FT-IR analysis is not conclusive but suggests the existence of a resonance structure that oscillates between the NH = C – O to the NH – C = O conformations involving the amide nitrogen and carbon atom of the carbonyl group. We confirmed this proposal for all alkylamides by using appropriate DFT/6-311++G(d,p) level of theory and confirmed that the NH = C – O enters with greater width. Our analysis also shows that the UV-vis spectra are strongly affected by the number of C = C bonds, and suffer an uncommon blue shift from S1 to the S3 structure. Our nonlinear optical (NLO) investigation based on DFT methods shows that the chromophores could have some use in optoelectronic due to they present second-hyperpolarizability of similar to 72 x 10(-36) esu, in competition with urea, PNA, and some chalcones. The analysis of the global reactive descriptors shows that spilanthol and its two analogs are classified as strong electrophilic chromophores with omega > 1.5 eV. However, the systematic inclusion of the C C bonds from S1 to S3 turns the system less nucleophile. While spilanthol is a strong nucleophile with N > 3.0 eV, the remaining S2 and S3 chromophores can be classified as moderate nucleophilic systems with 2.0 <= N <= 3.0 eV. These results suggest that S2 and S3 molecules have great potential as pharmacological agents. (C) 2020 Elsevier B.V. All rights reserved.
