Synthesis, Characterization and evaluation of antioxidant potential of 2, 6-diphenylpiperidine-4-one compounds and their novel imine derivatives

In search of potent molecules having antioxidant activity the present work was designed to synthesize 2, 6-diphenylpiperidine-4-one compounds (1a and 1b) and their imine derivatives (2a, 2b, 3a, and 3b). Compounds 1a and 1b were synthesized by Mannich condensation reaction. The method was found to be simple, convenient with high yield and products were easily separated. Compounds 1a and 1b serves as an intermediate for the preparation of highly functionalized novel imine derivatives. Oxime (2a, 2b) and carbothioamide (3a, 3b) derivatives of 1a and 1b compounds were produced by condensation reaction with hydroxyl amine hydrochloride and thiosemicarbazide respectively. These compounds were characterized by IR, EI-mass and (HNMR)-H-1 spectroscopy. The antioxidant activity of compounds was analyzed by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assay method. It was found that substituted aryl derivatives containing phenol and methoxy groups (1b, 2b and 3b) showed better antioxidant activity (IC50 values rang from 1.84-4.53 mu g/ml) than unsubstituted aryl derivative (1a, 2a and 3a) (IC50 rang from 6.46-11.13 mu g/ml). Compound 1b exhibited excellent antioxidant activity (IC50 1.84 +/- 0.15 mu g/ml) comparable to standard ascorbic acid (IC50 1.65 +/- 0.16 mu g/ml).

Efficacy of different dose of dexmedetomidine combined with remifentanil in colonoscopy: a randomized controlled trial

Background: Dexmedetomidine has advantages during colonoscopy as it allows the patient to cooperate during the procedure. Few studies examined the dexmedetomidine-remifentanil combination. This study was to evaluate the effects of different doses of the dexmedetomidine-remifentanil combination in colonoscopy. Methods: This was a prospective trial carried out at the Fourth Hospital of Hebei Medical University between 02/2018 and 10/2018. The patients were randomized: group I (dexmedetomidine 0.2 mu g.kg(-1)), group II (dexmedetomidine 0.3 mu g.kg(-1)), and group III (dexmedetomidine 0.4 mu g.kg(-1)), all combined with remifentanil. The primary outcomes were the patient’s body movements during the procedure and adverse events. Results: Compared with at admission (T-0), the SBP, HR, and RR at immediately after giving DEX (T-1), at the beginning of the examination (T-2), 5 min after the beginning of the examination (T-3), 10 min after the beginning of the examination (T-4), and at the end of the examination (T-5) in the three groups were all reduced (all P < 0.05), but all were within the clinically normal range. SpO(2) remained > 98% in all patients during the examination. Compared with T-0, the BIS values of the three groups were decreased at T-1 and T-2 (allP < 0.05). There were no significant differences in BIS among the three groups (allP > 0.05). The minimum BIS value in group III was lower than in groups I and II (P < 0.05). The degree of satisfaction with the anesthesia effect was higher in groups II and III that in group I (P < 0.05). No hypotension occurred, seven patients had bradycardia, and four patients had nausea/vomiting. Conclusions: Dexmedetomidine 0.3 mu g.kg(-1) combined with remifentanil was effective for colonoscopy and had few adverse reactions.

Unexpected rapid aerobic transformation of 2,2,6,6-tetraethyl-4-oxo (piperidin-1-yloxyl) radical by cytochrome P450 in the presence of NADPH: Evidence against a simple reduction of the nitroxide moiety to the hydroxylamine

Aminoxyl radicals (nitroxides) are a class of compounds with important biomedical applications, serving as antioxidants, spin labels for proteins, spin probes of oximetry, pH, or redox status in electron paramagnetic resonance (EPR), or as contrast agents in magnetic resonance imaging (MRI). However, the fast reduction of the radical moiety in common tetramethyl-substituted cyclic nitroxides within cells, yielding diamagnetic hydroxylamines, limits their use in spectroscopic and imaging studies. In vivo half-lives of commonly used tetra methyl-substituted nitroxides span no more than a few minutes. Therefore, synthetic efforts have focused on enhancing the nitroxide stability towards reduction by varying the electronic and steric environment of the radical. Tetraethyl-substitution at alpha position to the aminoxyl function proved efficient in vitro against reduction by ascorbate or cytosolic extracts. Moreover, 2,2,6,6-tetraethyl-4-oxo(piperidin-1-yloxyl) radical (TEEPONE) was used successfully for tridimensional EPR and MRI in vivo imaging of mouse head, with a reported half-life of over 80 min. We decided to investigate the stability of tetraethyl-substituted piperidine nitroxides in the presence of hepatic microsomal fractions, since no detailed study of their metabolic stability at the molecular level had been reported despite examples of the use of these nitroxides in vivo. In this context, the rapid aerobic transformation of TEEPONE observed in the presence of rat liver microsomal fractions and NADPH was unexpected. Combining EPR, HPLC-HRMS, and DFT studies on a series of piperidine nitroxides – TEEPONE, 4-oxo-2,2,6,6-tetramethyl(piperidin-1-yloxyl) (TEMPONE), and 2,2,6,6-tetraethyl-4-hydroxy(piperidin-1-yloxyl) (TEEPOL), we propose that the rapid loss in paramagnetic character of TEEPONE is not due to reduction to hydroxylamine but is a consequence of carbon backbone modification initiated by hydrogen radical abstraction in alpha position to the carbonyl by the P450-Fe(V)=O species. Besides, hydrogen radical abstraction by P450 on ethyl substituents, leading to dehydrogenation or hydroxylation products, leaves the aminoxyl function intact but could alter the linewidth of the EPR signal and thus interfere with methods relying on measurement of this parameter (EPR oximetry).

Asymmetric Michael Reaction of Aldehydes and alpha-Cyano alpha,beta-Unsaturated Esters Catalyzed by Diphenylprolinol Silyl Ether; a Facile Asymmetric Route to 3,4,5-Trisubstituted Piperidines

A highly enantioselective diphenylprolinol silyl ether-mediated asymmetric Michael reaction of a variety of aldehydes and beta-substituted alpha-cyano alpha,beta-unsaturated esters was developed. The organocatalytic conjugate addition provided synthetically useful chiral adducts possessing three consecutive stereocenters and suitably oriented functional handles that were readily transformed via a sequence of reductive-cyclization and subsequent epimerization to furnish single isomers of 3,4,5-trisubstituted piperidines with high levels of yield and excellent enantiopurity.

In silico evaluation and in vitro growth inhibition of Plasmodium falciparum by natural amides and synthetic analogs

Malaria, caused by protozoa of the genus Plasmodium, is a disease that infects hundreds of millions of people annually, causing an enormous social burden in many developing countries. Since current antimalarial drugs are starting to face resistance by the parasite, the development of new therapeutic options has been prompted. The enzyme Plasmodium falciparum enoyl-ACP reductase (PfENR) has a determinant role in the fatty acid biosynthesis of this parasite and is absent in humans, making it an ideal target for new antimalarial drugs. In this sense, the present study aimed at evaluating the in silico binding affinity of natural and synthetic amides through molecular docking, in addition to their in vitro activity against P. falciparum by means of the SYBR Green Fluorescence Assay. The in vitro results revealed that the natural amide piplartine (1a) presented partial antiplasmodial activity (20.54 mu M), whereas its synthetic derivatives (1m-IC50 104.45 mu M), (1b, 1g, 1k, and 14f) and the natural amide piperine (18a) were shown to be inactive (IC50 > 200 mu M). The in silico physicochemical analyses demonstrated that compounds 1m and 14f violated the Lipinski’s rule of five. The in silico analyses showed that 14f presented the best binding affinity (- 13.047 kcal/mol) to PfENR and was also superior to the reference inhibitor triclosan (- 7.806 kcal/mol). In conclusion, we found that the structural modifications in 1a caused a significant decrease in antiplasmodial activity. Therefore, new modifications are encouraged in order to improve the activity observed.

Microwave-Assisted N-Allylation/Homoallylation-RCM Approach: Access to Pyrrole-, Pyridine-, or Azepine-Appended (Het)aryl Aminoamides

A facile and diversity-oriented approach has been developed for the synthesis of pyrrole-, pyridine-, or azepine-appended (het)aryl aminoamides via the N-allylation/homoallylation-ring-closing metathesis (RCM) strategy. Microwave condition was efficiently utilized for N-allylation of (het)aryl aminoamides to synthesize di-, tri-, and tetra-allyl/homoallylated RCM substrates in good yields. All of the RCM substrates were successfully converted to respective pyrroles 6a-h, 13a,b, 15a,b, pyridines 11a-d, 13c, and azepines 7a,b via RCM. All of the five-, six-, and seven-membered N-heterocycles were synthesized in shorter reaction times with excellent yields without isomerization products. A one-pot reaction to synthesize compounds 6a and 6b without isolating corresponding RCM substrates was achieved successfully. The synthetic utility of the compound 6b has been demonstrated by synthesizing biaryl derivatives 17a,b under the microwave Suzuki coupling reaction condition.
