- Synthesis and evaluation of oryzalin analogs against Toxoplasma gondii
-
The synthesis and evaluation of 20 dinitroanilines and related compounds against the obligate intracellular parasite Toxoplasma gondii is reported. Using in vitro cultures of parasites in human fibroblasts, we determined that most of these compounds selectively disrupted Toxoplasma microtubules, and several displayed sub-micromolar potency against the parasite. The most potent compound was N1,N1-dipropyl-2,6-dinitro-4-(trifluoromethyl)-1,3- benzenediamine (18b), which displayed an IC50 value of 36 nM against intracellular T. gondii. Based on these data and another recent report [Ma, C.; Tran, J.; Gu, F.; Ochoa, R.; Li, C.; Sept, D.; Werbovetz, K.; Morrissette, N. Antimicrob. Agents Chemother. 2010, 54, 1453], an antimitotic structure-activity relationship for dinitroanilines versus Toxoplasma is presented.

- Synergistic herbicidal compositions comprising 4-benzoylisoxazole and dinitroaniline herbicides
-
The invention relates to synergistic compositions comprising: (a) a 4-benzoylisoxazole of formula (I) STR1 wherein R, R1, R2 and n are as defined in the specification; and (b) a dinitroaniline herbicide; and to the use of these compounds as herbicides.

- Pesticide-polymer systems prepared from vinyl monomers
-
Controlled release pesticide-polymer systems are prepared by the polymerization of vinyl monomers containing pendant pesticides. The vinyl monomers are prepared by reacting an acrylic acid derivative with a pesticide or a pesticide derivative having an active hydrogen. The pesticide-polymer systems prepared from the pesticide vinyl monomers release the active pesticide material by hydrolysis or chemical depolymerization under conditions of use.
