We report here the synthesis as well as antioxidant activity of a series of 2-aryl thiazolidine-4-carboxylic acids, including two novel derivatives. They were synthesized by nucleophilic cyclic condensation of L-cysteine hydrochloride with a range of aromatic aldehydes. Their in vitro antioxidant activity was evaluated by DPPH radical ...We report a simple and promising synthetic method to oxidize peptide hydrazides containing N-terminal thiazolidine as a protected cysteine. This yields the corresponding thioester via a peptide azide without decomposition of the thiazolidine ring. The newly developed protocol was validated by the synthesis of the bioactive peptide LacZα.Penicillinase-resistant penicillins are semisynthetic modifications of natural penicillins and their basic structure includes a thiazolidine ring connected to a beta-lactam ring. Bacterial resistance to penicillins is mediated by beta-lactamase, an enzyme that destroys the beta-lactam ring of penicillin, making it ineffective. Penicillinase ...

Compound 14a showed the most potent effects …Thiazolidinediones (TZDs) are the only pharmacologic agents that specifically treat insulin resistance. The beneficial effects of TZDs on the cardiovascular risk factors associated with insulin resistance have been well documented. TZD use has been limited because of concern about safety issues and side effects.

burley park howard city michigan A series of 12 new thiazolidine-2,4-dione derivatives were obtained by microwave-assisted synthesis. All compounds were physicochemically characterized by quantitative elemental C, H, N, S analysis and spectral data (mass spectrometry [MS], infrared [IR], and nuclear magnetic resonance [NMR]), with the results being in agreement with the expected data. scrolling text time wasterpo box 5517 sioux falls sd 57117 2.1.2.
