The present invention provides novel organic compounds of formula (I) or (Ia): which may be inhibitors of a selective subset of kinases belonging to the AGC or calmodulin kinase family, such as for example PKD-1/2/3, inhibitors of histone deacetylase (HDAC) phosphorylation, or inhibitors of other kinases. The selectivity of which would depend on the structural variation thereof, and for treatment of a disorder or disease mediated by those selected AGC or calmodulin family kinases. These organic compounds can be used to treat various PKD associated states such as heart failure, colorectal cancer, regulation of cell growth, autoimmune disorders, or hyperproliferative skin disorders.

Nucleophilic ring opening of aziridines involving attack of the nitrogen atom of Z-oxime anions generates nitrones which are then trapped in 1,3-dipolar cycloaddition reactions with N-methylmaleimide to afford 1:1 mixture of endo- and exo-cycloadducts.
The present invention is concerned with aryl-isoxazol-4-yl-imidazole derivatives of formula I:

are as defmed in the specification and pharmaceutically acceptable acid addition salts thereof. This class of compounds has high affinity and selectivity for GABA A α5 receptor binding sites and might be useful as cognitive enhancer or for the treatment of cognitive disorders like Alzheimer's disease.

The oximation of a variety of organic carbonyl compounds was efficiently carried out with NH2OH·HCl under microwave irradiation. The reactions were performed in water or water-ethanol as green solvents to give Z-aldoxime isomers from the corresponding aldehydes and E-ketoxime isomers from the corresponding ketones in a perfect selectively with excellent yields.

Oximes have many applications in organic synthesis1. These compounds have antimicrobial, antioxidant, antitumor, anti-depressive, antiviral agents, and anticonvulsant properties2-7. Some oximation methods have been reported8. However our ongoing attentions to the development of new modified methods in organic synthesis8-15, we have investigated the oximation of a variety of carbonylcompounds with
