Efficient approach to thiazolidinones via a one-pot three-component reaction involving 2-amino-1-phenylethanone hydrochloride, aldehyde and mercaptoacetic acid

A highly efficient three-component reaction has been developed for the synthesis of thiazolidinones involving the reaction of 2-amino-1-phenylethanone hydrochloride with an aromatic aldehyde and mercaptoacetic acid in the presence of diisopropylethylamine in a single pot. Critically, this reaction exhibited excellent chemoselectivity, with the nitrogen atom of the 2-amino-1-phenylethanone component reacting selectively with the aromatic aldehyde to give the corresponding Schiff base. Nucleophilic attack at the carbon of the Schiff base by the sulfur atom of mercaptoacetic, followed by a cyclocondensation reaction between the nitrogen and the carboxylic acid moiety afforded the desired thiazolidinones, which were fully characterized by spectroscopic techniques.

Inhibition of transformation in cultured rat tracheal epithelial cells by potential chemopreventive agents

Twenty-eight compounds were screened for chemopreventive activity by using a rat tracheal epithelial cell transformation inhibition assay. In this new assay, chemicals were tested for their ability to inhibit the formation of transformed rat tracheal epithelial cell colonies which arise following exposure to the carcinogen benzo(a)pyrene. The 15 positive compounds were N-acetylcysteine, bismuththiol, calcium glucarate, (¡À) catechin, diallyl disulfide, glycaric acid, D-glucaro-1,4-lactone, N-(4-hydroxyphenyl)retinamide, D-limonene, mesna, retinoic acid, rutin, quercetin, silymarin, and taurine. In examining the nature of compounds that inhibited rat tracheal epithelial cell transformation, several possible chemopreventive mechanisms appeared to be predominant: compounds that were positive (a) increased glutathione levels or enhanced conjugation; (b) increased cytochrome P-450 activity; (c) displayed nucleophilic activity; or (d) induced differentiation. Thirteen compounds were negative in the rat tracheal epithelial transformation inhibition assay: crocetin, difluoromethylornithine, ellagic acid, esculetin, enoxalone, ibuprofen, levamisole, nordihydroguaiaretic acid, L-2-oxothiazolidine-4-carboxylate, piroxicam, sodium butyrate, D-alpha-tocopherol acetate, and polyethylene glycol 400. It was evident from these results that this assay would not detect compounds that were (a) antipromoting in nature; (b) glutathione inhibitors; (c) differentiation inhibitors; (d) O6-methylguanine inhibitors; (e) organ specific; or (f) inactive. The rat tracheal epithelial cell transformation inhibition assay appeared to identify chemopreventive compounds that act at early stages of the carcinogenic process.

Synthesis, biological evaluation and modeling of hybrids from tetrahydro-1H-pyrazolo[3,4-b]quinolines as dual cholinestrase and COX-2 inhibitors

New tetrahydro-1H-pyrazolo[3,4-b]quinoline derivatives were designed, synthesized and characterized as dual anticholinestrase and cyclooxygenase-2 inhibitors. The in vitro and in vivo anti-cholinesterase evaluation exhibited promising activities with lower hepatotoxicity for many candidates compared to tacrine as a reference. Furthermore, their anti-inflammatory activity using in vitro (COX-1/COX-2) inhibitory assay demonstrated superior activity to celecoxib with higher selectivity indices for some compounds. In addition, some candidates showed extended anti-inflammatory activity by inhibiting COX-2 protein induction. Besides, in silico docking experiments of the active compounds against hAChE rationalized the observed in vitro AChE inhibitory activity. In conclusion, this work provides an extension of the chemical space of tetrahydro-1H-pyrazolo[3,4-b]quinoline chemotype for the anticholinestrase and anti-inflammatory activity. This would aid to minimize the possible neuroinflammation linked to the pathogenesis of Alzheimer’s disease.

Pharmacology and structural analysis of ligand binding to the orthosteric site of glutamate-like GluD2 receptors

The GluD2 receptor is a fundamental component of postsynaptic sites in Purkinje neurons, and is required for normal cerebellar function. GluD2 and the closely related GluD1 are classified as members of the ionotropic glutamate receptor (iGluR) superfamily on the basis of sequence similarity, but do not bind L-glutamate. The amino acid neurotransmitter D-Ser is a GluD2 receptor ligand, and endogenous D-Ser signaling through GluD2 has recently been shown to regulate endocytosis of a-amino- 3-hydroxy-5-methyl-4-isoxazolepropionic acid-type iGluRs during synaptic plasticity in the cerebellum, such as long-term depression. Here, we investigate the pharmacology of the orthosteric binding site in GluD2 by examining the activity of analogs of D-Ser and GluN1 glycine site competitive antagonists at GluD2 receptors containing the lurcher mutation (GluD2LC), which promotes spontaneous channel activation. We identify several compounds that modulate GluD2LC, including a halogenated alanine analog as well as the kynurenic acid analog 7-chloro- 4-oxo-1H-quinoline-2-carboxylic acid (7-chlorokynurenic acid; 7-CKA). By correlating thermodynamic and structural data for 7-CKA binding to the isolated GluD2 ligand binding domain (GluD2-LBD), we find that binding 7-CKA to GluD2-LBD differs from D-Ser by inducing an intermediate cleft closure of the clamshell-shaped LBD. The GluD2 ligands identified here can potentially serve as a starting point for development of GluD2- selective ligands useful as tools in studies of the signaling role of the GluD2 receptor in the brain.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 19771-63-2, help many people in the next few years.19771-63-2

2,4-Disubstituted quinolines with additional substituents in positions 5-8 have been found to have anthelmintic properties. A number of 2,4-dimethoxy-6- or 8-arylquinolines have potent activity against the sheep nematode Haemonchus contortus, with LD99 values of the same order of magnitude as levamisole. These arylquinolines maintain their activity against levamisole-, ivermectin- and thiabendazole-resistant strains of H. contortus.
