Synthesis, characterization and preliminary anti-inflammatory evaluation of 5-benzylidine thiazolidine-4-one derivatives

A series of four compounds which contain thiazolidine-4-one ring were synthesized and preliminarily assessed as anti-inflammatory agents with anticipated selectivity against COX-2 enzyme. The synthesized compounds structures have been recognised according to their spectral FT-IR and 1H NMR data. GOLD software was used to perform molecular docking study. The crystallographic structure of the molecular target cyclo-oxygenase enzyme-2 (COX-2) was taken from PDB database however, the celecoxib and naproxen were selected as a positive controls. The docking results of the newly synthesized compounds shown that they can enter the substrate-binding area of the active site .The compound (Ia) showed the highest PLP fitness,while compound (Ic) appeared to have the lowest binding ability compared to celecoxib which may be due to the presence of para nitro group that deactivates the ring system. Whereas In vivo acute anti-inflammatory effects of the synthesized compounds were evaluated in rats using egg-white induced edema model of inflammation. The tested compounds and the reference drug produced significant decrease in the paw edema with respect to the effect of propylene glycol 50%v/v (control group). Compounds Ia,b,d showed potent anti-inflammatory effect than naproxen (50mg/kg, i.p.) at 180 min., while compound Ic exhibited lower anti-inflammatory effect.

Synthesis of new azobenzene dyes clubbed with thiazolidinone moiety and their applications

Purpose: The purpose of this paper is to synthesize some new azobenzene dyestuffs clubbed with thiazolidinone moiety and their solicitation in dyeing polyester fabrics representing their antibacterial evaluation. Design/methodology/approach: Herein, the authors report the synthesis of new thiazolidinone moiety after the coupling of diazotized 4-aminoacetophenone with resorcinol. The newly synthesized dyes were characterized by IR, elemental analysis, mass spectroscopy and proton nuclear magnetic resonance (1H NMR) spectral studies. The characteristics of dyeing of these dyestuffs were evaluated at optimum conditions. Concurrent with dyeing of polyester fabric for synthesized dyes with their antibacterial activity was estimated. Antimicrobial activity of the dyed fabrics at different concentrations was evaluated against gram-positive and gram-negative bacteria. Findings: Synthesized azobenzene dyestuffs clubbed with thiazolidinone dyes were applied on polyester fabrics. It was remarked that the modified dyes exhibited better colourfastness properties. Furthermore, the synthesized dyes revealed antimicrobial activity against gram-positive and gram-negative bacteria. Research limitations/implications: The synthesized azobenzene dyes for polyester dyeing were not bore earlier. Practical implications: The azobenzene dyes were accountable for giving improved colourfastness properties on polyester fabrics. Social implications: The synthesized azobenzene derivatives are sensibly expensive and applicable dyes accompanied with good antimicrobial and anticancer activities. Originality/value: A common process could be affording textiles of colour and antibacterial assets. The newly synthesized dyes containing thiazolidinone moieties with azobenzene coupler showed interesting disperse colourant for polyester with good antibacterial activity.

(+)-Biotin: A Challenge for industrially viable total synthesis of natural products

The course of our investigation to develop an industrially viable total synthesis of (+)-biotin is described. Three synthetic approaches to (+)-biotin have been investigated to develop an efficient synthetic method using L-cysteine and thiolactone as a starting material and a key intermediate, respectively. Short steps, high yield and ease of operation of the approach would permit the hitherto most efficient access to (+)-biotin.

Synthesis of aryl-heteroaryl ureas (AHUs) based on 4-aminoquinoline and their evaluation against the insulin-like growth factor receptor (IGF-1R)

The insulin-like growth factor receptor (IGF-1R) is a receptor tyrosine kinase (RTK) involved in all stages of the development and propagation of breast and other cancers. The inhibition of IGF-1R by small molecules remains a promising strategy to treat cancer. Herein, we explore SAR around previously characterized lead compound (1), which is an aryl-heteroaryl urea (AHU) consisting of 4-aminoquinaldine and a substituted aromatic ring system. A library of novel AHU compounds was prepared based on derivatives of the 4-aminoquinoline heterocycle (including various 2-substituted derivatives, and naphthyridines). The compounds were screened for in vitro inhibitory activity against IGF-1R, and several compounds with improved activity (3-5 muM) were identified. Furthermore, a computational docking study was performed, which identifies a fairly consistent lowest energy mode of binding for the more-active set of inhibitors in this series, while the less-active inhibitors do not adopt a consistent mode of binding.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 461-72-3!, 1055361-35-7

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.

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.
