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.

Crystal Structure and Catalytic Activity of A Novel Cd(II) Coordination Polymer Formed by Dicarboxylic Ligand

A new Cd(II) coordination polymer, {[Cd-3(L)(2)(DMF)(2)(H2O)(2)] H2O}n (H2L = 1,3-bisbenzyl-2imidazolidine- 4,5-dicarboxylic acid) was synthesized by one-pot synthesis method from 1,3-bisbenzyl-2imidazolidine- 4,5-dicarboxylic acid, NaOH, DMF, and Cd(NO3)(2) 4H(2)O. Its structure was determined by elemental analysis and single crystal X-ray diffraction. Structural analysis shows that three Cd(II) ions are all six-coordinated with four oxygen atoms of four 1,3-bisbenzyl-2-imidazolidine-4,5-dicarboxylate ligands and two O atoms from two DMF molecules (Cd1) or two oxygen atoms of two coordinated H2O molecules (Cd2 and Cd3) to form an octahedral coordination geometry. The Cd(II) coordination polymer displays a 1D chained structure by the bridging carboxylate groups from 1,3-bisbenzyl-2-imidazolidine4,5- dicarboxylate ligands. The conversion of benzaldehyde is 90.9%, which is 40 similar to 50% higher than those of the other three aldehydes (4-methylbenzaldehyde, p-methoxybenzaldehyde and 3chlorobenzaldehyde), so the Cd(II) coordination polymer catalyst shows better catalytic activity for the coupling reaction of benzaldehyde, phenylacetylene, and piperidine than the other three aldehydes.

The Abuse Potential of Novel Synthetic Phencyclidine Derivative 1-(1-(4-Fluorophenyl)Cyclohexyl)Piperidine (4 ‘-F-PCP) in Rodents

The dissociative anesthetic phencyclidine (PCP) and PCP derivatives, including 4 ‘-F-PCP, are illegally sold and abused worldwide for recreational and non-medical uses. The psychopharmacological properties and abuse potential of 4 ‘-F-PCP have not been fully characterized. In this study, we evaluated the psychomotor, rewarding, and reinforcing properties of 4 ‘-F-PCP using the open-field test, conditioned place preference (CPP), and self-administration paradigms in rodents. Using Western immunoblotting, we also investigated the expression of dopamine (DA)-related proteins and DA-receptor-mediated downstream signaling cascades in the nucleus accumbens (NAc) of 4 ‘-F-PCP-self-administering rats. Intraperitoneal administration of 10 mg/kg 4 ‘-F-PCP significantly increased locomotor and rearing activities and increased CPP in mice. Intravenous administration of 1.0 mg/kg/infusion of 4 ‘-F-PCP significantly enhanced self-administration during a 2 h session under fixed ratio schedules, showed a higher breakpoint during a 6 h session under progressive ratio schedules of reinforcement, and significantly altered the expression of DA transporter and DA D1 receptor in the NAc of rats self-administering 1.0 mg/kg 4 ‘-F-PCP. Additionally, the expression of phosphorylated (p) ERK, pCREB, c-Fos, and FosB/Delta FosB in the NAc was significantly enhanced by 1.0 mg/kg 4 ‘-F-PCP self-administration. Taken together, these findings suggest that 4 ‘-F-PCP has a high potential for abuse, given its robust psychomotor, rewarding, and reinforcing properties via activation of DAergic neurotransmission and the downstream signaling pathways in the NAc.

Novel agonist of alpha(4)beta(2)* neuronal nicotinic receptor with antinociceptive efficacy in rodent models of acute and chronic pain

Objective: To demonstrate the antinociceptive and antihypersensitivity mechanisms of Cris-104 (1- {2-[5-(4-fluoropheny1)-1H-pyrazol-4-yl]ethyl}piperidine), a novel selective alpha(4)beta(2)* nicotinic acetylcholine receptor (nAChR) agonist, in rodent acute/inflammatory and chronic pain models. Materials and methods: Hot-plate and formalin tests in mice were used to examine Cris-104-induced antinociceptive effects on thermal/inflammatory pain. Cris-104 effects on hypersensitivity, norepinephrine (NE) release in the spinal dorsal horn, and neuronal activity in the locus coeruleus (LC) were examined in rats with lumbar spinal nerve ligation using behavioral, microdialysis, and extracellular recording methods. Cris-104 effects on spontaneous locomotion were examined in an open-field test. Results: Cris-104 induced dose-dependent antinociception effects in hot-plate and formalin tests, and these effects were blocked by the general nAChR antagonist mecamylamine, the selective alpha(4)beta(2)* nAChR antagonist dihydro-beta-erythroidine, and the alpha(2)-adrenoceptor antagonist yohimbine, but not by the alpha(2)-adrenoceptor antagonist prazosin. Systemic and spinally perfused Cris-104 increased NE concentrations in microdialysates from the spinal cord in both normal and SNL, rats. Systemic Cris-104 increased neuronal activity in the LC of normal rats. Mecamylamine blocked the effects of Cris-104 on spinal NE release and LC neuronal activity. Systemic Cris-104 did not affect locomotor activity significantly. Conclusion: The alpha(4)beta(2) neuronal nAChR agonist, Cris-104, was effective for treatment of pain via descending noradrenergic inhibition of pain signaling.

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.

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.

Mass spectrometric characterization of carfentanil metabolism in human, dog, and rat lung microsomes via comparison to chemically synthesized metabolite standards

Purpose The metabolism of carfentanil was assessed using human, dog, and rat pulmonary microsomes. Mass spectrometry based analysis allowed for metabolite identification and species differentiation. Participation of different metabolic enzymes in carfentanil biotransformation was also assessed. Methods Metabolite profiling was accomplished by incubating 10 mu M carfentanil in human, dog, and rat lung microsomes. The metabolites were separated and analyzed by ultra-high performance liquid chromatography/high-resolution mass spectrometry. Results In total, 18 metabolites were detected. Nine metabolites were authentically identified through comparison to synthesized reference standards. In human lung microsomes, nine metabolites were identified. In dog lung microsomes, 15 metabolites were identified with three being dog specific. In rat lung microsomes, 15 metabolites were identified and two were rat specific. Proposed metabolic pathways includedN-dealkylation, monohydroxylation, dihydroxylation,N-oxidation of piperidine ring nitrogen, and ketone formation. Participation of enzymes CYP2B6, CYP2E1, CYP2J2, and CYP3A4/5 to carfentanil metabolism was suggested by selective enzymatic inhibition. Conclusions The pulmonary clearance in human lung microsomes was lower than the previously reported hepatic metabolism suggesting organ specific metabolic rates. The contribution of multiple cytochrome P450 enzymes to human, dog, and rat pulmonary microsomal carfentanil biotransformation varied between species. The identified metabolites may provide useful markers for possible forensic and clinical determination of the mode of ingestion but the use of dog and rat animal models was not indicated. To our knowledge, this is the first reported use of chemically synthesized reference standards for the unequivocal identification of lung carfentanil metabolites.

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.
