By taking into account the level of baseline functioning, researchers interested in memory decline in people with DS have mostly focused on verbal list learning and scene learning Sabbagh and Edgin This view is also supported by the results of Holland et al. The findings of this review are especially relevant given that current diagnosis procedures ICD and DSM-V criteria emphasize declines in mecer wnp-0109 functions and therefore in this population may fail to facilitate the early detection and diagnosis of dementia when it does occur. More research needs to be conducted in order to decide on the exact measures to be included in this tool set, given the intra-individual variability in task performance in people with DS Krinsky-McHale et al.

Initial changes reported in BPSD and reflected subsequent diagnosis. In one of mfcer studies, executive dysfunction was investigated by looking at verbal intrusions as an indicator of disruption of inhibition control Kitler et al. Moreover, considering that in the general population amnestic MCI is widely accepted as the prodromal stage of AD, an alternative should be proposed for people with DS, to reflect this difference in progression. Cyanoimidazolinone 44 was more effective in overall broadleaf control and significantly safer on soybeans and corn. We discovered that esters of the cyanoimidazolinones are unstable under conditions which do not normally affect the imidazolinones. When 41 was treated with dilute sodium hydroxide at room temperature in hopes of hydrolyzing the methyl ester, hydrolysis and ring opening occurred, affording acid diamide Sixteen to nineteen weeks after treatment, the plots were planted with rape and sugarbeets.

Four weeks later the plots showed much injury to the sugarbeets and rape. These results indicate that methyl ester 41 was undergoing little if any breakdown in the soil after weeks. The instability of this cyanoimidazolinone at elevated pH is not an indication of reduced soil persistence.

We have evidence that suggests that the rate of breakdown or half-life of the imidazolinone esters is related to the nature of the ester and also to the substituents on the aryl ring unpublished data, American Cyanamid Co. We are currently studying the rates of breakdown of other esters in the cyanoimidazolinone area with various substituents on the pyridine ring to determine if any compounds show the required combination of excellent weed control, crop selectivity mecer wnp-0109 reduced soil persistence. Synthesis: Acid Salts.

A great deal of time was spent on trying to prepare the acids from various esters of mecer wnp-0109 or from the parent imidazolinones.


The method which was found to be most successful is shown below. Cleavage of the trimethylsilylethyl ester mecer wnp-0109 accomplished with tetrabutylammonium fluoride at room temperature, affording 54 in quantitative yield.


Mecer wnp-0109 use of anhydrous cesium fluoride or anhydrous potassium fluoride in place of tetrabutylammonium fluoride gave no reaction. Conventional methods of dissociating tetrabutylammonium salts mecer wnp-0109 carboxylic acids, such as dilute hydrochloric acid, concentrated hydrochloric acid, acidic alumina or acidic ion exchange resins failed with the cyanoimidazolinones, affording either recovered salt or decomposition.

The free acids could be isolated by passing the salts through dry column silica gel packed in conventional gravity columns. The salts were also shown to dissociate to varying extents on reversed phase HPLC. mecer wnp-0109

Biological Activity: Acid Salts. Cyanoimidazolinone 54 was less effective than 55 in conttolling ragweed, morningglory and foxtail but was mecer wnp-0109 on corn and showed no injury to soybeans. Cyanoimidazolinone 54 was subjected to soil persistence tests in the greenhouse in which pots which had been sprayed with 54 were reseeded with sorghum 30 days after soil application at various rates. The same was done with pots which had been treated with imazethapyr. The reseeded pots that had originally been sprayed with cyanoimidazolinone 54 showed no significant sorghum injury. When cyanoimidazolinone 54 was applied in the field to soybeans postemergence at various rates, the weed control in the plots sprayed with 54 was significantly less than in those sprayed with imazethapyr These results suggest that 54 was undergoing facile breakdown to non-herbicidal compounds in the field too rapidly.


Conclusions The N-hydroxyimidazolinones were synthesized via novel chemistry but did not show any significant advantage over their imidazolinone counterparts in terms of herbicidal activity or crop selectivity. The N-chloroimidazolinones showed excellent herbicidal activity in some cases, but have mecer wnp-0109 no indication to date that they break down more rapidly than their parent imidazolinones to non-toxic species in the soil. The N-cyanoimidazolinones, on the other hand, showed good combinations of weed control and crop safety while showing the potential for reduced soil persistence.

We have evidence that indicates mecer wnp-0109 certain N-cyanoimidazolinones are less stable than their parent imidazolinones in the greenhouse and in the field. Congress Pesticide Chem. Tseng, S.
