Synthesis of Fused Six-Membered Lactams to Isoxazole and Isoxazoline by Sequential Ugi Four-Component Reaction and Intramolecular Nitrile Oxide Cyclization

The advanced organic chemistry experiments describe the preparation of fused six-membered lactams to isoxazole and isoxazoline by employing Ugi four-component reaction (U-4CR) and intramolecular nitrile oxide cyclization (INOC) synthetic sequence. The experiments were carried out in 28 h (overnight for U-4CR) and 2 h (for INOC) using commercially available starting materials. The two-step reaction involves the in situ imine formation in the one-pot multicomponent reaction and in situ nitrile oxide formation in the INOC. The experiments are useful in the organic chemistry curriculum for the introduction of a onepot multicomponent reaction and 1,3-dipolar cycloaddition reactions.

EFFECTS OF MYOSMINE ON ANTIOXIDATIVE DEFENCE IN RAT LIVER

Myosmine [3-(1-pyrrolin-2-yl) pyridine] is an alkaloid structurally similar to nicotine, which is known to induce oxidative stress. In this study we investigated the effects of myosmine on enzymatic and nonenzymatic antioxidative defence in rat liver. Wistar rats received a single i.p. injection of 19 mg kg(-1) of myosmine and an oral dose of 190 mg kg(-1) by gavage. Nicotine was used as a positive control. Through either route of administration, myosmine altered the hepatic function by decreasing the levels of reduced glutathione, superoxide dismutase, and glutathione peroxidase activities on one hand and by increasing malondialdehyde, catalase, and glutathione reductase activity on the other. Compared to control, both routes caused significant lipid peroxidation in the liver and altered hepatic enzymatic and non-enzymatic antioxidative defences. The pro-oxidant effects of myosmine were comparable with those of nicotine.

Bioprocessing optimization for efficient simultaneous removal of methylene blue and nickel by Gracilaria seaweed biomass

The pollution of water by heavy metal ions and dyes, particularly from industrial effluents, has become a global environmental issue. Therefore, the treatment of wastewater generated from different industrial wastes is essential to restore environmental quality. The efficiency of Gracilaria seaweed biomass as a sustainable biosorbent for simultaneous bioremoval of Ni2+ and methylene blue from aqueous solution was studied. Optimization of the biosorption process parameters was performed using face-centered central composite design (FCCCD). The highest bioremoval percentages of Ni2+ and methylene blue were 97.53% and 94.86%; respectively, obtained under optimum experimental conditions: 6 g/L Gracilaria biomass, initial pH 8, 20 mg/L of methylene blue, 150 mg/L of Ni2+ and 180 min of contact time. Fourier Transform Infrared Spectroscopy (FTIR) spectra demonstrated the presence of methyl, alkynes, amide, phenolic, carbonyl, nitrile and phosphate groups which are important binding sites involved in Ni2+ and methylene blue biosorption process. SEM analysis reveals the appearance of shiny large particles and layers on the biosorbent surface after biosorption that are absent before the biosorption process. In conclusion, it is demonstrated that the Gracilaria seaweed biomass is a promising, biodegradable, ecofriendly, cost-effective and efficient biosorbent for simultaneous bioremoval of Ni2+ and methylene blue from wastewater effluents.

General Synthesis of Secondary Alkylamines by Reductive Alkylation of Nitriles by Aldehydes and Ketones

The development of C-N bond formation reactions is highly desirable due to their importance in biology and chemistry. Recent progress in 3d metal catalysis is indicative of unique selectivity patterns that may permit solving challenges of chemical synthesis. We report here on a catalytic C-N bond formation reaction-the reductive alkylation of nitriles. Aldehydes or ketones and nitriles, all abundantly available and low-cost starting materials, undergo a reductive coupling to form secondary alkylamines and inexpensive hydrogen is used as the reducing agent. The reaction has a very broad scope and many functional groups, including hydrogenation-sensitive examples, are tolerated. We developed a novel cobalt catalyst, which is nanostructured, reusable, and easy to handle. The key seems the earth-abundant metal in combination with a porous support material, N-doped SiC, synthesized from acrylonitrile and a commercially available polycarbosilane.

Inhibitory effect of 3,4-diaryl-3-pyrrolin-2-one derivatives on cyclooxygenase 1 and 2 in murine peritoneal macrophages

AIM: To develop a whole-cell assay based on murine peritoneal macrophages and evaluate the inhibitory effect of candidate compounds on cyclooxygenase-1 (COX-1) and COX-2. METHODS: Macrophages were stimulated with calcimycin or hpopolysaccharide (LPS) for various periods. Their abilities to convert endogenous arachidonic acid to 6-keto-PGF(1alpha) or PGE(2) were examined by radioimmunoassay (RIA). RNA level of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and COX-1/2 was detected by reverse transcription polymerase chain reaction (RT-PCR) using specific primers. RESULTS: Rofecoxib selectively inhibited LPS-induced, COX-2-derived PGE(2) synthesis with an IC50 value of (4.7+/-0.5) nmol/L compared with maximum inhibitory ratio of 17.3 % for the inhibition of calcimycin induced, COX-1-derived 6-keto-PGF(1alpha) synthesis. Indomethacin exhibited dual inhibitory effects on COX-1 and COX-2 with IC50 of (4.7+/-1.1) nmol/L and (7.1+/-1.2) nmol/L, respectively. Two series of 17 compounds were tested. Most of compounds in series 11 showed comparable inhibitory activities to rofecoxib on COX-2. The relative position of the sulfonylphenyl group to the lactam carbonyl group has important effects on COX-2 inhibitory activity. CONCLUSION: The established whole cell assay is appropriate for drug-design oriented in vitro assay. 3,4-Diaryl-3-pyrrolin-2-one derivatives were proved to be prospective new type of COX-2 selective inhibitors.

Synthesis of Novel 3D-Rich alpha-Amino Acid-Derived 3-Pyrazolidinones

Synthetic approaches towards novel 3-pyrazolidinone derivatives functionalized at positions N(1) and/or C(5) were studied. 5-Aminoalkyl-3-pyrazolidinones were prepared in four steps from N-protected glycines via Masamune-Claisen homologation, reduction, O-mesylation, and cyclisation with a hydrazine derivative. The free amines were prepared by acidolytic deprotection. Title compound was also prepared by ‘ring switching’ transformation of N-Boc-pyrrolin-2(5H)-one with hydrazine hydrate. Hydrogenolytic deprotection of 5-(N-alkyl-N-Cbz-aminomethyl) pyrazolidine-3-ones followed by cyclisation with 1,1′-carbonyldiimidazole (CDI) gave two novel representatives of perhydroimidazo[1,5-b] pyrazole, which is an almost unexplored heterocyclic system. Amidation of 3-oxopyrazolidine-5-carboxylic acid gave the corresponding carboxamides in moderate yields. Diastereomeric non-racemic carboxamides obtained from (S)-AlaOMe and (S)-ProOMe were separated by MPLC.
