determinants required for the actions of MNS and to develop more potent tyrosine kinase inhibitors and antiplatelet agents, a new series of beta-nitrostyrene derivatives were synthesized and pharmacologically characterized. The beta-nitrostyrene derivatives inhibited thrombin- or collagen-induced human platelet aggregation, ATP secretion, GPIIb/IIIa activation and protein tyrosine phosphorylation. In recombinant

Nitroaceticacid was fused with eighteen aromatic aldehydes and gave the respective β-nitrostyrenes. It was more reactive towards aldehydes with electron-withdrawing than with electron-releasing substituents. Nitromethane adducts or nitro-olefins were formed from the reaction of enamines with nitroaceticacid. Di-(3,4-dihydro-4-nitromethylquinazolinium) carbonate was obtained in good yield from quinazoline
An efficient method for the synthesis of conjugated nitro-olefins from α,β-unsaturated acids under extremely mild conditions usingcericammoniumnitrate (CAN) at room temperature in acetonitrile in moderate to good yields is described.

The present invention is in the field of chemistry and biotechnology. The present invention relates to cell-based microarrays, improved methods for forming such arrays, and methods for using such arrays in diagnostics, therapeutics and research. The invention particularly concerns microarrays in which ligands of a target cells are immobilized to the array support via ligand-binding molecules bound to an oligonucleotide that is hybridized to a support-immobilized oligonucleotide.
