Low catalyst loadings for ligand-free copper(I)-oxide-catalyzed N-arylation of methanesulfonamide in water

A simple and practical protocol for the cross-coupling of methanesulfonamide and aryl iodides under ligand-free copper(I)-oxide-catalyzed conditions in water is reported. The method allows the preparation of a wide variety of synthetically useful N-arylated methanesulfonamides in good to excellent yields (up to 90 %) under the optimized conditions. A convenient and efficient ligand-free method using a copper(I) oxide catalyst at 130 C in water was developed for the N-arylation of methanesulfonamide with aryl iodides. A variety of functionalized aliphatic and cyclic sulfonamides were coupled with different substituted aryl halides to give the corresponding N-arylated products in good to excellent yields under the optimized conditions.

New treatments for COPD

Chronic obstructive pulmonary disease (COPD) is a major health problem worldwide. It is characterised by chronic inflammation in the lungs that leads to progressive chronic airflow obstruction. The main strategy for treating COPD is control of the chronic inflammation. However, current anti-inflammatory treatments fail to prevent disease progression. New long-acting bronchodilators and their combinations are currently under development. Research has been focused on identifying the key inflammatory regulators. CXCR2 antagonists inhibit neutrophilic inflammation; inhibitors of phosphodiesterase-4 (PDE4), p38 mitogen-activated protein kinase (p38), Janus kinases and IL-6 have also shown some promising effects. There is an emerging need for identification of key modulators of the oxidative stress-regulated corticosteroid function aiming the development of monotherapies which will resolve any side effects issues currently faced.

Processes for the production of heterocyclic compounds

A ketonic heterocyclic compound having at least two heteroatoms in the ring is prepared by reacting a difunctional compound having the general formula STR1 in which R1, R2, R3 and R4 are members of the group consisting of aliphatic, aromatic, cycloaliphatic and heterocyclic hydrocarbons which may contain functional groups selected from –OH, –OR5, –COOH, –COOR5, –CN, –Cl, –Br, –I, –F, and –CO–R5, wherein R5 is an aliphatic, aromatic, cycloaliphatic or heterocyclic hydrocarbon; X is oxygen or sulphur; Y is sulphur or nitrogen; n is an integer ranging from 1 to 3, or zero; R6 is a hydrogen or a hydrocarbon radical included in the above definition of R1 R2 R3 and R4 ; and m is the valence of Y, with carbon monoxide and oxygen in the presence of a catalyst selected from selenium, selenium compounds and complexes of copper, in the temperature range of from room temperature to 80 C and in the pressure range of from 1 to 10 atmospheres.

The role of E3 ubiquitin-ligases MuRF-1 and MAFbx in loss of skeletal muscle mass

The ubiquitin?proteasome system (UPS) is the main regulatory mechanism of protein degradation in skeletal muscle. The ubiquitin-ligase enzymes (E3s) have a central role in determining the selectivity and specificity of the UPS. Since their identification in 2001, the muscle specific E3s, muscle RING finger-1 (MuRF-1) and muscle atrophy F-box (MAFbx), have been shown to be implicated in the regulation of skeletal muscle atrophy in various pathological and physiological conditions. This review aims to explore the involvement of MuRF-1 and MAFbx in catabolism of skeletal muscle during various pathologies, such as cancer cachexia, sarcopenia of aging, chronic kidney disease (CKD), diabetes, and chronic obstructive pulmonary disease (COPD). In addition, the effects of various lifestyle and modifiable factors (e.g. nutrition, exercise, cigarette smoking, and alcohol) on MuRF-1 and MAFbx regulation will be discussed. Finally, evidence of potential strategies to protect against skeletal muscle wasting through inhibition of MuRF-1 and MAFbx expression will be explored.

Medicinal prospects of antioxidants: A review

Free radicals generated due to exposure of radiation, environmental pollutants and as by-products of metabolised drugs. These free radicals are antagonized by molecules which are antioxidant in nature. Antioxidants are the substances which inhibit oxidation. They are moreover acknowledged as ?free radical scavengers? as they form minor reactive species via radicals. Based on origin, they are categorised into two types: exogenous and endogenous antioxidants. An Antioxidant reduces the occurrence of different disorders like: aging, cancer, diabetes, inflammation, liver disease, cardiovascular disease, cataract and nephrotoxicity and neurodegenerative disorders. Dietary antioxidants are thought to have potential capacities to avert oxidative anxiety induced diseases. This review figures the various researches on pharmacological activity of natural along with synthetic antioxidant molecules.

Nutrition and immunity in elderly

Aging is associated with increase in chronic disease as well as infections and associated morbidity. This is often throughout to be secondary immunosenescene. Whether this decline in immune function with aging is due to the aging process per Se or is secondary to poor health, inflammation, and other life style factors particularly suboptimal nutritional status. With aging a variety of changes are observed in the immune system, which translate into less effective innate and adaptive immune responses and increased susceptibility to infections. Antioxidant vitamins and trace elements [vitamins C, E, selenium, copper and zinc] counteract potential damage caused by reactive oxygen species to cellular tissues and modulate immune cell function through regulation of redox-sensitive transcription factors and affect production of cytokines and prostaglandins. Adequate intake of vitamins B[6], folate, B[12], C,E, and of selenium, Zn, copper and iron supports a Th I cytokine-mediated immune response with sufficient production of proinflammatory cytokine. Vitamin A and D play important roles in both cell mediated and humoral antibody response. Nutrient supplementation is often accompanied by an improvement in immune function.

Synthesis and in vitro anti-tumor activity of some new sebacoyl chloride based heterocycles

Background: N-Heterocycles are of special interest because, many natural and synthetic bioactive compounds are found to be N-containing heterocycles and they constitute an important class of pharmacophores in medicinal chemistry. Recently, 1,2,3-triazoles have been found to possess a vast range of vital applications in the agrochemical, pharmaceutical, and materials field. In addition, various compounds of the 1,2,3-triazole family have shown a broad spectrum of biological properties such as antibacterial, and anti-HIV activity. 1,3,4- Oxadiazoles are important oxygen and nitrogen containing heterocyclic compounds, they possess desirable electronic and charge-transport properties. Methods: Two mammalian cell lines were grown in RPMI-1640 medium, supplemented with 10% heat inactivated FBS, 50 units/mL of penicillin and 50 g/mL of streptomycin and maintained at 37 C in a humidified atmosphere containing 5% CO2. The cells were maintained as ?monolayer culture? by serial sub-culturing. Preliminary cytotoxicity was performed using SRB method. Results: Sebacoyl chloride and decanedihydrazide dihydrochloride are utilized as versatile building blocks to annulate a series of novel azole and/ or azine systems. The in vitro anti-tumor activities of the synthesized compounds were evaluated against human breast cancer cell line (MCF-7) and human cervical cancer cell line (HeLa). The obtained data indicated that the majority of the tested compounds possess significant anti-tumor activities against the tested tumor cell lines. Conclusion: Sebacoyl chloride, decanedihydrazide dihydrochloride and N-nucleophiles are useful precursors for the synthesis of different functionalized N- heterocycles. The cytotoxic study revealed that the majority of the tested compounds possess significant anti-tumor activity towards the tested tumor cell lines.
