Precocenes (PI and PII) and 114 of their analogs (PAs) were synthetized and tested on C. remanei embryos for their precocene-like (P-like) activities resulting in unusual development at sublethal doses. The P-like activity was quantitated by plotting the probit of

Antigonadotropic activities of Precocene 1 (P1), Precocene 2 (P2) and Ethoxyprecocene 2 (EP2) on the seed bug Oxycarenus lavaterae (F.) (Heteroptera, Lygaeidae), are reported. EP2 proved to be the most active compound followed by P2 and P1, which agrees with

[reaction: see text] The thionium ion, generated through a cyclopropylcarbinyl-cyclobutyl ring expansion, is, for the first time, intramolecularly intercepted by activated aromatic rings to generate new versatile 2a-methyl-8b-(phenylsulfanyl-1,2a,3,8b-tetrahydro-2H-cyclobuta[c]chromenes.

The mechanism of the hepatotoxicity of precocene I has been investigated in male, Sprague-Dawley rats. Administration of a single dose of precocene I caused a large depletion of liver glutathione (GSH) levels that was both time and dose dependent. Concomitant

Inhibitors of deoxynivalenol production by Fusarium graminearum are useful for protecting crops from deoxynivalenol contamination. We isolated precocenes and piperitone from the essential oils of Matricaria recutita and Eucalyptus dives, respectively, as specific inhibitors of the production of 3-acetyldeoxynivalenol, a
