Synthesis of pyrazoline-thiazolidinone hybrids with trypanocidal activity

A series of novel 4-thiazolidinoneepyrazoline conjugates have been synthesized and tested for anti-Trypanosoma brucei activity. Screening data allowed us to identify five thiazolidinoneepyrazoline hybrids, which possess promising trypanocidal activity, with IC50 <1.2 muM. The highest active thiazolidinoneepyrazoline conjugates 3c and 6b (IC50 values of 0.6 mM and 0.7 mM, respectively) were 6-times more potent antitrypanosomal agents than nifurtimox. In addition, these compounds, as well as 6d and 6e had selectivity index higher than 50, and were more selective than nifurtimox. SAR study included substituent variations at the pyrazoline moiety, modifications of N3 position of the thiazolidinone portion, elongation of the linker between the heterocycles, as well as rhodanineeisorhodanine isomerism. It was also shown that methyl or aryl substitution at the thiazolidinone N3-position is crucial for trypanocidal activity. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. COA of Formula: C3H5NOS, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2682-49-7, in my other articles.

Spectral studies of polymer supported chelates

The reaction between polystyrene 3-formylsalicylate and 2-Aminobenzylalcohol in DMF in the presence of ethyl acetate results in the formation of polystyrene N-(2-hydroxymethylphenyl)-2′-hydroxybenzylideneimine-3′- carboxylate (I). A benzene suspension of I reacts with mercaptoacetic acid undergoes cyclization and forms polystyrene N-(2-hydroxymethylphenyl)-C-(3′-carboxy-2′-hydroxyphenyl)thiazolidine-4-one, PSCH2?LH2 (II). A DMF suspension of II reacts with Mn(II) and Cd(II) ions and forms the corresponding polystyrene-anchored coordination compounds, [PSCH2?LHMn(OAc)(DMF)3] (III) and [PSCH2?LHCd(OAc)(DMF)] (IV). The polystyrene-anchored coordination compounds have been characterized on the basis of elemental analyses, spectral (IR, reflectance) studies and magnetic susceptibility measurements. II behave as a monobasic bidentate OS donor ligand in the coordination compounds. An octahedral structure for III and tetrahedral structure for IV are suggested.

Preparation, antibacterial evaluation and preliminary structure-activity relationship (SAR) study of benzothiazol- and benzoxazol-2-amine derivatives

In this study, a novel benzothiazol- and benzooxazol-2-amine scaffold with antibacterial activity was designed and synthesized. Preliminary structure-activity relationship analysis displayed that compound 8t with a 5,6-difluorosubstituted benzothiazole was found to be a potent inhibitor of Gram-positive pathogens, and exhibited some potential against drug-resistant bacteria and without cytotoxicity in therapeutic concentrations. In addition, molecular docking studies indicated that Staphylococcus aureus methionyl-tRNA synthetase might be the possible target of these compounds. Taken together, the present study provides an effective entry to the synthesis of a good lead for subsequent optimization and a new small molecule candidate drug for antibacterial therapeutics.

Antioxidants and chronic obstructive pulmonary disease

Antioxidants represent an attractive therapeutic avenue for individuals with chronic obstructive pulmonary disease (COPD). Cigarette smoke, the major cause of COPD, contains very high concentrations of gaseous and soluble oxidants that can directly induce cell injury and death. Furthermore, particulate matter in cigarette smoke activates lung macrophages that subsequently attract neutrophils. Both neutrophils and macrophages from the lungs of cigarette smokers continuously release large amounts of superoxide and hydrogen peroxide through the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex. Once individuals with COPD stop smoking, the neutrophilic inflammation in the airways and lung parenchyma persists, as do the markers of oxidative stress. Several animal models of cigarette smoke-induced injury have provided evidence that various antioxidants may prevent inflammation and morphological changes associated with COPD however, evidence of benefit in patients is less abundant. Although oxidants can inactivate alpha-1 antitrypsin and other protective proteins, damage lung tissue, and increase mucus production, they also are essential for killing pathogens and resolving inflammation. This review will examine the pre-clinical and clinical evidence of a role for antioxidants in the therapy of patients with COPD.
