Organocatalyzed C-N bond-forming Reactions for the Synthesis of Amines and Amides

The synthesis of organonitrogen compounds via C-N bond formation emerges as a versatile route for drug discovery. Most of the pharmaceuticals and natural products, which are predominantly used generally contain amine functionalities and amide linkages in their structure. Traditionally, the synthesis is done by using several metal catalysts and hazardous chemicals. The organocatalyzed synthetic protocol provides a sustainable and eco-compatible route for the synthesis of organonitrogen compounds and at the same time also avoids metal contamination. The main aim of this Review is to provide an overview of the organocatalyzed amine and amide synthesis via C-N bond formation reactions. We hope this Review provides valuable information about the organocatalyzed reaction to enable the development of more sustainable routes to form these linkages.

Antibacterial Activity of Novel 18 beta-Glycyrrhetinic Hydrazide or Amide Derivatives

Through a facile structural modification on the natural bioactive ingredient 18 beta-glycyrrhetinic acid(GA), a series of novel GA hydrazide or amide derivatives was obtained, and their final molecular frameworks were characterized by NMR and HRMS analysis. Antibacterial bioassays revealed that some of the GA hydrazide or amide derivatives were able to suppress the growth of three tested plant pathogens. Particularly, compound 3c exhibited excellent in vitro activity against Xanthomonas oryzae pv. Oryzae (Xoo), Pseudomonas syringae pv. actinidiae(Psa), and Xanthomonas axonopodis pv. citri(Xac), providing the EC50 values of 5.89, 16.1, and 3.64 mu g/mL, respectively. The data were better than those of the positive controls thiodiazole copper(92.7, 77.8, and 89.9 mu g/mL, respectively) and bismerthiazol(31.1, 125.6, and 77.4 mu g/mL, respectively). In addition, in vivo experiments suggested that, compared with thiodiazole copper(41.93% and 39.73%, respectively), compound 3c exerted prominently curative and protective activities against rice bacterial leaf blight at 200 mu g/mL with the control effects of 52.36% and 51.40%, respectively. Given these obtained results, GA hydrazide or amide derivatives could serve as the feasible leads for exploring highly bioactive substrates.

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.

Synthesis of Fluorescent Diphenylanthracene-Based Calix[4]arene Derivatives and their Complexation with Alkali Metal Cations

Two novel fluorescent calix[4]arenes comprising diphenylanthracene moiety at the lower rim were synthetizedand their complexation with alkali metal cations in acetonitrile/dichloromethane and methanol/dichloromethane mixtures (phi = 0.5) was studied experimentally and by classical molecular dynamics and quantum chemical calculations. The monosubstituted calixarene derivative (L1) proved to be a poor cation receptor, whereas the ester-based macrocycle (L2) exhibited rather high affinity towards lithium, sodium and potassium cations, particularly in MeCN/CH2Cl2. All complexation reactions were enthalpically controlled, whereby the overall stability was the largest in the case of sodium complex. The computational investigations provided an additional insight into the complexation properties and structures of complex species. The molecular dynamics simulations indicated the occurrence of inclusion of solvent molecules in the calixarene hydrophobic cavity of the free and complexed ligand, which was found to significantly affect the complexation equilibria.

The synthetic versatility of the Tiffeneau-Demjanov chemistry in homologation tactics

The Tiffeneau-Demjanov rearrangement can be regarded as an interesting alternative to the more common semi-pinacol transposition. It is usually employed for ring extension but, under specific conditions, it can also be used for ring contraction. Compared to other techniques, such as the Demjanov rearrangement or homologations with diazo compounds, the Tiffeneau-Demjanov pathway presents attractive features including high yielding and selective processes. Ring enlargements follow very strict and simple rules, such as the movement of the less substituted carbon and retention of the configuration. The rearrangement process is mainly affected by steric factors, due to presence of neighbouring groups, rather than electronic ones. The ring contraction may be achieved positioning the amine within the ring, thus achieving a high level of control. Unfortunately, applications of the reaction in modern homologation chemistry are rare; therefore, the aim of the review is re-proposing to the synthetic community the versatility of this venerable reaction and thus, spurring its employment for tackling challenging homologations processes.

Gene ontology analysis of expanded porcine blastocysts from gilts fed organic or inorganic selenium combined with pyridoxine

Background: Gene ontology analysis using the microarray database generated in a previous study by this laboratory was used to further evaluate how maternal dietary supplementation with pyridoxine combined with different sources of selenium (Se) affected global gene expression of expanded porcine blastocysts. Data were generated from 18 gilts randomly assigned to one of three experimental diets (n=6 per treatment): i) basal diet without supplemental Se or pyridoxine (CONT); ii) CONT +0.3 mg/kg of Na-selenite and 10mg/kg of HCl-pyridoxine (MSeB(6)10); and iii) CONT +0.3mg/kg of Se-enriched yeast and 10 mg/kg of HCl-pyridoxine (OSeB(6)10). All gilts were inseminated at their fifth post-pubertal estrus and euthanized 5days later for embryo harvesting. Differential gene expression between MSeB(6)10 vs CONT, OSeB(6)10 vs CONT and OSeB(6)10 vs MSeB(6)10 was performed using a porcine embryo-specific microarray. Results: There were 559, 2458, and 1547 differentially expressed genes for MSeB(6)10 vs CONT, OSeB(6)10 vs CONT and OSeB(6)10 vs MSeB(6)10, respectively. MSeB(6)10 vs CONT stimulated 13 biological processes with a strict effect on RNA binding and translation initiation. OSeB(6)10 vs CONT and OSeB(6)10 vs MSeB(6)10 impacted 188 and 66 biological processes, respectively, with very similar effects on genome stability, ceramide biosynthesis, protein trafficking and epigenetic events. The stimulation of genes related with these processes was confirmed by quantitative real-time RT-PCR. Conclusions: Gene expression of embryos from OSeB(6)10 supplemented gilts was more impacted than those from MSeB(6)10 supplemented gilts. Whereas maternal OSeB(6)10 supplementation influenced crucial aspects of embryo development, maternal MSeB(6)10 supplementation was restricted to binding activity.

When the Surface Matters: Prebiotic Peptide-Bond Formation on the TiO2 (101) Anatase Surface through Periodic DFT-D2 Simulations

The mechanism of the peptide-bond formation between two glycine (Gly) molecules has been investigated by means of PBE-D2* and PBE0-D2* periodic simulations on the TiO2 (101) anatase surface. This is a process of great relevance both in fundamental prebiotic chemistry, as the reaction univocally belongs to one of the different organizational events that ultimately led to the emergence of life on Earth, as well as from an industrial perspective, since formation of amides is a key reaction for pharmaceutical companies. The efficiency of the surface catalytic sites is demonstrated by comparing the reactions in the gas phase and on the surface. At variance with the uncatalyzed gas-phase reaction, which involves a concerted nucleophilic attack and dehydration step, on the surface these two steps occur along a stepwise mechanism. The presence of surface Lewis and Bronsted sites exerts some catalytic effect by lowering the free energy barrier for the peptide-bond formation by about 6 kcal mol(-1) compared to the gas-phase reaction. Moreover, the co-presence of molecules acting as proton-transfer assistants (i.e., H2O and Gly) provide a more significant kinetic energy barrier decrease. The reaction on the surface is also favorable from a thermodynamic standpoint, involving very large and negative reaction energies. This is due to the fact that the anatase surface also acts as a dehydration agent during the condensation reaction, since the outermost coordinatively unsaturated Ti atoms strongly anchor the released water molecules. Our theoretical results provide a comprehensive atomistic interpretation of the experimental results of Martra etal. (Angew. Chem. Int. Ed. 2014, 53, 4671), in which polyglycine formation was obtained by successive feedings of Gly vapor on TiO2 surfaces in dry conditions and are, therefore, relevant in a prebiotic context envisaging dry and wet cycles occurring, at mineral surfaces, in a small pool.

Chemical exchange rotation transfer (CERT) on human brain at 3 Tesla

Purpose: To test the ability of a novel pulse sequence applied in vivo at 3 Tesla to separate the contributions to the water signal from amide proton transfer (APT) and relayed nuclear Overhauser enhancement (rNOE) from background direct water saturation and semisolid magnetization transfer (MT). The lack of such signal source isolation has confounded conventional chemical exchange saturation transfer (CEST) imaging. Methods: We quantified APT and rNOE signals using a chemical exchange rotation transfer (CERT) metric, MTRdouble. A range of duty cycles and average irradiation powers were applied, and results were compared with conventional CEST analyses using asymmetry (MTRasym) and extrapolated magnetization transfer (EMR). Results: Our results indicate that MTRdouble is more specific than MTRasym and, because it requires as few as 3 data points, is more rapid than methods requiring a complete Z-spectrum, such as EMR. In white matter, APT (1.5 +/- 0.5%) and rNOE (2.1 +/- 0.7%) were quantified by using MTRdouble with a 30% duty cycle and a 0.5-mu T average power. In addition, our results suggest that MTRdouble is insensitive to B-0 inhomogeneity, further magnifying its speed advantage over CEST metrics that require a separate B-0 measurement. However, MTRdouble still has nontrivial sensitivity to B-1 inhomogeneities. Conclusion: We demonstrated that MTRdouble is an alternative metric to evaluate APT and rNOE, which is fast, robust to B-0 inhomogeneity, and easy to process.
