Application

4-Cyclopentene-1,3-dione was used in the synthesis of 2-methoxymethylene-4-cyclopentene-1,3-dione and chrysotrione B (2-acylcyclopentene-1,3-dione derivative). It was used to investigate the influence of sulfiydryl group-specific reagents on activity of bovine heart phospholipid exchange protein.

Two phospholipid exchange proteins from bovine heart have been purified approximately 2000-fold and judged greater than 90% pure. The proteins are similar in molecular weight (both 33,400 by polyacrylamide gel electrophoresis and 23,500 by gel filtration), in amino acid composition

The molecular pathways by which the cyclopentenone prostaglandins (PGA and PGJ series) inhibit cell growth and tumorigenicity are poorly understood. These cellular responses may be caused by specific regulation of growth-related and stress-induced genes. A variety of prostaglandins were tested

We designed chiral 2-nitroimidazole derivatives containing a 2-aminomethylene-4-cyclopentene-1,3-dione moiety as antiangiogenic hypoxic cell radiosensitizers. Based on results of molecular orbital calculations, the 2-aminomethylene-4-cyclopentene-1,3-dione moiety is expected to show high electrophilicity comparable to that of the 2-methylene-4-cyclopentene-1,3-dione moiety included in TX-1123

Pathogenic fungi continue to develop resistance against current antifungal drugs. To explore the potential of agricultural waste products as a source of novel antifungal compounds, we obtained an unbiased GC-MS profile of 151 compounds from 16 commercial and experimental cultivars

Facile, two-step synthesis and kinetic characterization of new chemical probes for selective labeling of sulfenic acid (-SOH) in proteins are presented. The synthesis route relies on the simple and highly efficient Michael addition of thiol containing tags or linkers to
