Automatic procedures for the synthesis of difficult peptides using oxyma as activating reagent: A comparative study on the use of bases and on different deprotection and agitation conditions

Solid-Phase Peptide Synthesis (SPPS) is a rapid and efficient methodology for the chemical synthesis of peptides and small proteins. However, the assembly of peptide sequences classified as difficult poses severe synthetic problems in SPPS for the occurrence of extensive aggregation of growing peptide chains which often leads to synthesis failure. In this framework, we have investigated the impact of different synthetic procedures on the yield and final purity of three well-known difficult peptides prepared using oxyma as additive for the coupling steps. In particular, we have comparatively investigated the use of piperidine and morpholine/DBU as deprotection reagents, the addition of DIPEA, collidine and N-methylmorpholine as bases to the coupling reagent. Moreover, the effect of different agitation modalities during the acylation reactions has been investigated. Data obtained represent a step forward in optimizing strategies for the synthesis of difficult peptides.

Fibroblast growth factor receptor modulators employing diamines with reduced phospholipidosis-inducing potential

SUN13837 (1), a fibroblast growth factor receptor modulator, has been an attractive candidate for treating neurodegenerative diseases. However, one of its metabolites, N-benzyl-4-(methylamino)piperidine (BMP), turned out to possess phospholipidosis-inducing potential (PLIP) in vitro. To obtain SUN13837 analogs with reduced phospholipidosis risk, we replaced BMP with other diamines possessing low PLIP. Our effort led to the discovery of compound 6 with increased efficacy. Further structural modifications to reduce hydrogen bond donors afforded 17 with improved brain exposure. Oral administration of 17 at 1 mg/kg once daily for 10 days showed enhanced recovery of coordinated movement in a rat acute stroke model, suggesting that it is a promising follow-up compound for 1 with reduced risk of phospholipidosis.

Structural modification of the tripeptide KPV by reductive glycoalkylation of the lysine residue

Peptides that exhibit enzymatic or hormonal activities are regulatory factors and desirable therapeutic drugs because of their high target specificity and minimal side effects. Unfortunately, these drugs are susceptible to enzymatic degradation, leading to their rapid elimination and thereby demanding frequent dosage. Structurally modified forms of some peptide drugs have shown enhanced pharmacokinetics, improving their oral bioavailability. Here, we discuss a novel glycomimetic approach to modify lysine residues in peptides. In a model system, the epsilon-amine of Ts-Lys-OMe was reductively alkylated with a glucose derivative to afford a dihydroxylated piperidine in place of the amine. A similar modification was applied to H-KPV-NH2, a tripeptide derived from the alpha-melanocyte stimulating hormone (alpha-MSH) reported to have antimicrobial and anti-inflammatory properties. Antimicrobial assays, under a variety of conditions, showed no activity for Ac-KPV-NH2 or the alpha-or epsilon-glycoalkylated analogs. Glycoalkylated peptides did, however, show stability toward proteolytic enzymes.

Highly selective 1-pentene epoxidation over Ti-MWW with modified microenvironment of Ti active sites

A titanosilicate/H(2)O(2)catalytic system was applied to process the liquid-phase selective epoxidation of 1-pentene to 1,2-epoxypentane (EP). The effects of titanosilicate topology (MWW, MFI, MSE, MEL, MOR, and *BEA), solvent, H2O/H(2)O(2)ratio, catalyst amount, reaction temperature, pressure, and time on the EP production were investigated systematically. The Ti-MWW/H2O2/acetonitrile system exhibited the highest 1-pentene conversion of 72.9% together with high EP selectivity of 99.9% and H(2)O(2)utilization efficiency of 91.5%. Moreover, it was proved that the Ti active sites located inside the intralayer 10-membered ring sinusoidal channels catalyzed the epoxidation process primarily owing to their supplying more steric fitness for 1-pentene molecules. A piperidine (PI)-assisted structural rearrangement of Ti-MWW was performed to further enhance the catalytic activity, almost doubling the turnover number value. The evolution of the microenvironment of Ti active sites in this structural rearrangement process was carefully investigated, revealing the coordination of N atoms in PI molecules to the Ti atoms. More importantly, we identified that the hexa-coordinated Ti sites with the PI molecules as ligand could significantly accelerate H(2)O(2)activation, the effect of which far exceeded the inhibition effect caused by the electronegativity increase of Ti active sites.

Alternative Reactivity of Leucine 5-Hydroxylase Using an Olefin-Containing Substrate to Construct a Substituted Piperidine Ring

Applying enzymatic reactions to produce useful molecules is a central focus of chemical biology. Iron and 2-oxoglutarate (Fe/2OG) enzymes are found in all kingdoms of life and catalyze a broad array of oxidative transformations. Herein, we demonstrate that the activity of an Fe/2OG enzyme can be redirected when changing the targeted carbon hybridization from sp(3) to sp(2). During leucine 5-hydroxylase catalysis, installation of an olefin group onto the substrate redirects the Fe(IV)-oxo species reactivity from hydroxylation to asymmetric epoxidation. The resulting epoxide subsequently undergoes intramolecular cyclization to form the substituted piperidine, 2S,5S-hydroxypipecolic acid.

Luminescent complexes of iridium(iii) with aliphatic amines and detection of biogenic amines

The straightforward reaction of [Ir-2(ppy)(4)(mu-Cl)(2)] with an excess of aliphatic amines yields luminescent iridium complexes of general formula [IrCl(ppy)(2)(amine)] [amine = n-octylamine (1), t-butylamine (2), piperidine (3)]. The higher sterical hindrance of the amine in complex 2 was the responsible of its equilibrium with the starting materials. The luminescence of 1 and 3 has been studied showing emission at 508 and 509 nm respectively. As the aliphatic amines can be considered models of biogenic amines, this luminescence has been used to explore the viability of this reaction in the detection of biogenic amines. The exposition to vapors of biogenic amines of a solution of [Ir-2(ppy)(4)(mu-Cl)(2)] in CH2Cl2 or in different solid supports, showed that it was possible to detect the amines in a quick and easy way, with limits of detection value (in solution of methylene chloride) of 4.8 mu M for cadaverine.

Immobilization of Small-Molecule Ligands Containing Secondary or Tertiary Amine Groups onto TiO2-Supported Ru Catalysts Driven by the Hydrophobic Effect

A strategy for effectively immobilizing small-molecule ligands onto TiO2-supported Ru catalysts is described. The immobilization was based on a simple two-phase centrifugation technique and driven by the hydrophobic effect, likely leading to the formation of hydrophobic clusters of small-molecule ligands. By using this strategy, a library of ligands containing secondary or tertiary amine groups and hydrophobic chains were successfully immobilized onto TiO2-supported Ru catalysts. Of these ligands, ligands containing 2,2,6,6-tetramethyl-1-piperidine-N-oxyl (TEMPO) moieties significantly improved the selectivity for aldehyde at high conversion in aerobic oxidation of alcohols, resulting from the inhibition of auto-oxidation of aldehydes. This strategy can generate diversity in preparation of organic/inorganic hybrid catalysts.

Synthesis and pharmacological evaluation of 3-[5-(aryl-[1,3,4]oxadiazole-2-yl]-piperidine derivatives as anticonvulsant and antidepressant agents

In the present study, we have synthesized a series of fifteen nipecotic acid 1,3,4-oxadiazole based hybrids with significant (60-78%) yields. All the compounds were characterized by using different spectroanalytical techniques such as FT-IR, H-1 NMR, C-13 NMR, and elemental analysis. This design strategy was validated by using in vivo anti-epileptic and anti-depressant bioassay models. Anti-convulsant activity was evaluated using subcutaneous pentylenetetrazol (scPTZ) in mice and MES induced seizure. Among a spectrum of activities, three compounds (4i, 4m, and 4n) displayed significant activity against pentylenetetrazole (scPTZ) induced seizures. No disruptions in motor co-ordination were observed in mice pretreated with the test compounds in the rotarod test. Their influence on the safety profile of elevated serum levels of biochemical markers such as hepatic and renal toxicity has been found to be safe. The derivatives also show marked anti-depressant activity, devoid of serotonergic augmentation as assessed using the despair swim test, 5-hydroxytryptophan (5-HTP)-induced head twitch test and learned helplessness test. In silico docking studies targeted on homology modelled GABA transporter 1 (GAT1) protein shows the critical enzyme-ligand interactions leading to the inhibition of the GAT1 transporter. The compound 4m was found to be the most active compound among all the synthesized compounds. (C) 2020 Published by Elsevier B.V. on behalf of King Saud University.
