In 2-(2-alkenoyloxy)-5-alkoxytropones, showing a monotropic smectic A phase, the introduction of a double bond lowers the melting and clearing points as well as the recrystallization temperatures.
在显示单向近晶 A 相的 2-(2-烯酰氧基)-5-烷氧基托酮中,双键的引入降低了熔点和清光点以及重结晶温度。

An object of the present invention is to provide a novel trans-2-decenoic acid derivative or a pharmaceutically acceptable salt thereof and to provide a pharmaceutical agent which contains said compound as an active ingredient and has a highly safe neurotrophic factor-like activity or an alleviating action for side effect induced by administration of anti-cancer agents. The trans-2-decenoic acid derivative or a pharmaceutically acceptable salt thereof which is the compound of the present invention is specifically represented by the formula (1):
(In the formula, Y is —O—, —NR— or —S—, R is hydrogen atom, alkyl group, dialkylaminoalkyl group or the like and W is a substituent such as dialkylaminoalkyl group) and has a quite high usefulness as a pharmaceutical agent such as a preventive or therapeutic agent for dementia, Alzheimer's disease, Parkinson's disease, depression, etc., a treating or repairing agent for spinal cord injury.
3-Acyltetramic acids having various substituents at the 1-and 5-positions, and possessing a tricarbonylmethane structure, were synthesized and tested for antimicrobial activity to investigate the structure-activity relationships. It was found that the nature of the substituents at the 1-and 5-positions as well as the 3-position is an important factor for activity to inhibit the growth of Bacillus subtillis and Staphylococcus aureus.
