Synthesis and antioxidant activity of some new coumarinyl-1,3-thiazolidine-4-ones.
A series of Schiff's bases (E)-N-2-aryliden-2-(4-methyl-2-oxo-2H-chromen-7-yloxy)acetohydrazides 2a-l and N-(2-(substituted phenyl)-4-oxo-thiazolidin-3-yl)-2-(4-methyl-2-oxo-2H-chromen-7-yloxy)acetamides 3a-l were synthesized and evaluated for their antioxidant activity by the phosphomolybdenum method. Most of the Schiff's bases and thiazolidine-4-ones bearing two hydroxyl groups on the phenyl ...
متن کاملNew Thiazolidine-4-ones of Ferulic Acid with Antioxidant Potential
New thiazolidine-4-one derivatives of ferulic acid have been synthesized in one step ("one-pot") by cyclization of ferulic acid hydrazide with different aromatic aldehydes and mercaptoacetic acid. The structure of the synthesized compounds was proved by infrared (IR) and nuclear magnetic resonance (H-NMR) spectroscopy. The in vitro antioxidant potential of the synthesized compounds was evaluate...
متن کاملDesign, Synthesis and Characterization of Some Novel 3-Coumarinyl- 5-aryliden-1,3-thiazolidine-2,4-diones and Their Antioxidant Activity
In our effort to obtain biologically active compounds, new 3,5-disubstituted 1,3-thiazolidine-2,4diones (5a – r) were synthesized. A series of 5-arylmethylidene-1,3-thiazolidine-2,4-diones (3a – r) were prepared by Knoevenagel reaction from 1,3-thiazolidine-2,4-dione (2) and appropriate aromatic aldehydes. Condensation of 3a – r with 7-hydroxy-4-bromomethyl-2-oxo-2H-chromene (1) afforded novel ...
متن کاملAnalgesic activity of new synthetic thiazolidine-4-ones derivatives.
Ten new synthetic thiazolidine-4-ones derivatives (5 chlorothiazolidine-4-ones, 3 methoxythiazolidine-4-ones and 2 hydoxythiazolidine-4-ones) having different substituents at R1, R2 and R3 were evaluated for their analgesic activity using different animal models and their structure activity relationship was also elucidated. Chlorothiazolidine-4-ones and methoxythiazolidine-4-ones exhibited anal...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
