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.

Voltage-clamp experiments using the three-microelectrode voltage clamp technique were performed on ventroabdominal flexor muscles of the crustacean Atya lanipes. Potassium and chloride currents were found to underlie the normal, passive response of the muscle. Blocking potassium currents with tetraethylammonium and

The cavity ringdown absorption spectrum of 4-cyclopentene-1,3-dione was recorded near 487 nm in a room-temperature gas cell. The very weak band system (epsilon approximately 0.05 dm3 mol-1 cm-1) in this region is due to the T1(n,pi*) <-- S0 electronic transition.

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
