Regioselective synthesis of unsymmetrical biheteroaryls via copper(II)-catalyzed cascade annulation

A facile and efficient copper-catalyzed cascade annulation of an imidazoheterocycle with salicylaldehyde, piperidine, and terminal alkyne was developed to afford unsymmetrical biheteroaryl derivatives. A variety of biheteroaryl structural motifs containing furans and imidazoheterocycles have been synthesized in ambient air in high yields. The experimental results suggest that the reaction proceeds through a sequential non-radical 5-exo-dig cyclization process.

Copper-catalyzed asymmetric dearomative borylation: new pathway to optically active heterocyclic compounds

Chiral N-heterocyclic organoboronates represent promising intermediates for the preparation of various bioactive and pharmaceutical compounds. We recently reported the first asymmetric dearomative borylation of indoles by copper-catalyzed borylation. Then we further developed dearomatization/enantioselective borylation sequence. Chiral 3-boryl-tetrahydropyridines and chiral boryl-tetrahydroquinolines via the copper(I)-catalyzed regio-, diastereo- and enantioselective borylation of 1,2-dihydropyridines and 1,2-dihydroquinilines, which were prepared by the partial reduction of the corresponding pyridine or quinoline derivatives. This dearomatization/enantioselective borylation procedures provide a direct access to chiral piperidines and tetrahydroquinolines from readily available pyridines or quinolines in combination with the stereospecific transformation of the stereogenic C-B bond.

Synthesis of Isofagomine Derivatives as New Fluorescence pH Indicators/Glycosidase Inhibitors

Inhibitor protonation of azasugars of the isofagomine type when bound to enzyme can be investigated using photon induced electron transfer (PET) quenching of an attached fluorophore. For this purpose, Isofagomine, iso-d-galacto-fagomine, and iso-l-gulo-fagomine were converted toN-(10-chloroanthracenenyl-9-alkyl) derivatives where the alkyl group contained one, two, or three methylene groups. The new derivatives displayed pH dependent fluorescence; as the ammonium forms they were fluorescent, while 90-99 % of the fluorescence was quenched in the amine forms. The 3 isofagomine derivatives were competitive inhibitors ofT. Maritima Iota-glucosidase withK(i)values from 0.37-4.6 tau M. Similarly, the iso-d-galacto-fagomines inhibitedA. Niger Iota-galactosidase withK(i)values from 63-2000 nm. When bound to the enzymes the inhibitors displayed between 1-15 % fluorescence.

Functionalized spirooxindole-indolizine hybrids: Stereoselective green synthesis and evaluation of anti-inflammatory effect involving TNF-alpha and nitrite inhibition

Stereoselective synthesis of a small library of novel spiroheterocyclic hybrids including indolizine, oxindole, and substituted piperidine units has been accomplished in [bmim]Br using a [3 + 2]cyclo-addition strategy in good yield and were tested for their anti-inflammatory activities. The effects of compounds (4a-o) against inflammation were studied using carrageenan-induced hind paw oedema, croton oil-induced ear oedema, and cotton pellet-induced granuloma models. Among the heterocyclic hybrids, compounds 4d, 4g, and 4o showed significant anti-inflammatory activities against acute and chronic inflammatory models. These compounds also showed significant inhibition of PGE2, TNF-alpha, and nitrite levels in carrageenan-induced hind paw oedema. Thus it is evident from our study that these novel spiroheterocyclic hybrids 4d, 4g, and 4o displayed significant anti-inflammatory effects that involve the reduction of PGE(2), TNF-alpha, and nitrite levels.

Synthesis and antithrombotic activity of 1-benzyl-N ‘-benzylidenepiperidine-3-carbohydrazide derivatives

Platelet aggregation inhibition and interfering with clot formation are essential tools for antithrombotic therapy and there is a need for discovering new antithrombotic agents. In this study, we synthesized a series of benzylidenepiperidine-3-carbohydrazide derivatives (1f-11f), bearing various selected substituents on both the piperidine ring nitrogen and the hydrazide nitrogen. The synthesized compounds were characterized by FTIR, (HNMR)-H-1 spectroscopic techniques, CHN/O elemental analysis and electrospray ionization mass spectra. All new 1-benzyl-N0-benzylidenepiperidine-3-carbohydrazides were evaluated for their antiplatelet aggregation activities (against platelet aggregation induced by AA, ADP and collagen separately) and anticoagulant activities [protrombin time (PT) and partial thromboplastin time (PTT)]. Antiplatelet aggregation activity of the new derivatives was measured using human plasma on an APACT 4004 aggregometer. All the compounds were mainly effective on ADP pathway of platelet aggregation compared with collagen and AA pathways. The most potent compound on platelet aggregation induced by ADP is compound 2f with 87% aggregation inhibition activity at 0.5 mmol/l concentration. The synthesized compounds were further investigated for their anticoagulant action via the two PT and PTT models. They all showed higher PT and PTT values compared with the blank control sample. The most potent compounds are 5f, 6f, 7f and 1f. All compounds were obtained in good yield and further evaluated for their antiplatelet and anticoagulant activity.

Rapid naked-eye colorimetric detection of gaseous alkaline analytes using rhodamine B hydrazone-coated silica strips

A novel chemosensor based on rhodamine B hydrazone was developed. The chemical structure of the new rhodamine B hydrazone was verified using different spectroscopic techniques. The surface morphology of the rhodamine B hydrazone was determined by scanning electron microscopy (SEM), which revealed self-assembly in the form of layered aggregations. A thin layer chromatography (TLC) test strip impregnated with rhodamine B hydrazone was fabricated to function as a qualitative optical tool for the rapid detection of alkaline vapors (1 min), including ammonia, triethylamine, piperidine, pyridine, and hydrazine monohydrate. The colorimetric sensing of alkaline vapors was achieved through color changes of the rhodamine B hydrazone-coated silica strips from pink to colorless or faded pink upon exposure to the vapors of the alkaline analytes at 0.1 mu l. The colorimetric changes can be tracked by the naked-eye or by using a smartphone camera. Reversible ring-opening/ring-closure of the spirolactam rings of the probe was confirmed by UV/vis and H-1 NMR analyses. The colorimetric detection of alkaline vapors occurred through deprotonation of the ring-opened amide form of the bis-hydrazone material supported on the TLC silica strip. The proposed detection method offers several advantages, including facile fabrication, simple operation without the need for a special device or skilled operators, easy handling, and real-time sensing of alkaline vapors.

Structure-directed formation of the dative/covalent bonds in complexes with C70MIDLINE HORIZONTAL ELLIPSISpiperidine

The combined experimental-computational study has been performed to investigate the complexes formed between C-70 carbon allotrope and piperidine. The results of FT-IR, H-NMR, and C-NMR measurements, together with the calculations based on the DFT approach and molecular dynamics simulations, prove the existence of dative/covalent bonding in C70MIDLINE HORIZONTAL ELLIPSISpiperidine complexes. The dative bond forms not only at the region of five- and six-membered rings, observed previously with C-60, but also at the region formed of six-membered rings. The structure, i.e., nonplanarity, explains the observed dative bond formation. New findings on the character of interaction of secondary amines with C-70 bring new aspects for the rational design of modified fullerenes and their applications in electrocatalysis, spintronics, and energy storage.

Synthesis, evaluation, and molecular properties prediction of substituted cinnamoylpiperazine derivatives as potential antinociceptive and anticonvulsive agents

A series of novel cinnamoylpiperazine derivatives (5a-5l) were synthesized as potential antinociceptive, and anticonvulsive agents. Various heterocyclic systems like piperidine, morpholine, piperazine, and N-arylpiperazine were combined with cinnamoyl or methylenedioxy cinnamoyl moieties to obtain a series of constrained analogs of cinnamides. Of these, compound 5e possessing 4-fluorophenyl substitution on the piperazine ring exhibited good antinociceptive activity in capsaicin and formalin-induced nociception methods, and also significant anticonvulsant activity in pentylenetetrazole and maximal electroshock-induced seizure methods. Further, all the derivatives were studied for molecular and preadmet properties. The activities of compound 5e were supported by molecular and preadmet properties for its in silico oral bioavailability and drug-likeness.
