Abstract

Fourteen precocene-1 (P1) derivatives differing at C-7 were synthetized and tested for their antiallatal activities on Locusta migratoria (in vitro and in vivo) and nematocidal effects on Caenorhaditis elegans. An outstanding antiallatal effect was produced by 7-propargyloxy-P1 in vitro. It caused an elevated rate of mortality when applied in vivo to locusts or nematodes. The antiallatal effect of 7-cyclopentyloxy-P1 was not accompanied by toxicity. Aralkyloxy substitution at C-7 eliminated the precocene activity.
