✦ Synopsis
Analogs of the natural substance (E)-hex-2-en-lbal which occurs naturally in green plants and is known to have microbiocidal properties were synthesized and studied with respect to their antifungal properties. Saturated and unsaturated aldehydes, alcohols, carbon acids and enolacetate were tested against various fungi by applying these compounds either over the gaseous phase or in suspension. The following ranking was observed on the basis of fungicidal activity: enolacetate of 2-ethylhex-2-en-1-a1 > 2-ethylhex-2-enoic acid > 2-ethylhex-d-en-l-aI> 2-ethylhex-2-en-1-01. Saturated analogs showed the same order of activity as the unsaturated ones, however, thry were less efficient.
The effects on the ultrastructural changes were analyzed in Mucor mucedo exposed to conoentrations of the analogs that inhibited growth. Main effects were observed on mitochondria1 and nuclear mcmbranes. The kind of destruction caused by enolacetate of 2-ethylhex-2-en-1 -a1 differed from the other substances tested. Aspects of the mode of action are discussed.
