Synthesis and antifungal activity of a series of novel 1,2-disubstituted propenones
摘要:
To find an antifungal agent other than those of the imidazole and triazole series, a new class of 1,2-disubstituted propenones I and II was prepared and tested for antifungal activity. Comparison of the structure-activity relationships showed that the conjugated structure of carbonyl and exomethylene groups in I and II plays an important role in potent antifungal activity. However, it is noteworthy that compounds 53, 54, and 56, which have a hydroxymethyl or methoxymethyl group instead of an exo-methylene group in I, also showed potent activity. Although many compounds exhibited strong antifungal activity in vitro, none showed activity in vivo of oral efficacy against subacute systemic candidiasis in mice.

A compound represented by formula (I) or a salt thereof has an inhibitory action on abscisic acid 8′-hydroxylase CYP707A. The compound or a salt thereof can be used as a plant growth regulator.
wherein R is a C1-6 alkyl group, and the C1-6 alkyl group optionally have a substituent selected from the group consisting of a halogen atom and a C1-6 alkoxy group.
