Novel Color Formers Having a Phenothiazine Moiety.

A Novel Color Image Compression Method Using Eigenimages

Since the birth of multi–spectral imaging techniques, there has been a tendency to consider and process this new type of data as a set of parallel gray–scale images, instead of an ensemble of an n–D realization. Although, even now, some researchers make the same assumption, it is proved that using vector geometries leads to better results. In this paper, first a method is prop...

Synthesis and Biological Studies of Some New Chalcone and 1,4 -Dihydropyridine Derivatives Containing Phenothiazine Moiety

Structure-activity relationships of cephalosporins having a (dimethylisoxazolidinio)vinyl moiety at their 3-position.

A series of cephalosporins having a (dimethylisoxazolidinio)vinyl group at their 3-position were synthesized to investigate their structure-activity relationships. With regard to the olefin geometry, the (E)-vinyl compound exhibited higher in vitro activity than the (Z)-compound. Regarding the C-7 substituents, the replacement of 2-aminothiazole with 5-amino-1,2,4-thiadiazole increased the anti...

BNAs: novel nucleic acid analogs with a bridged sugar moiety.

This article deals with our recent studies on the synthesis of BNAs (Bridged Nucleic Acids), novel nucleic acid analogs bearing a preorganized sugar conformation by a bridged structure. Duplex- and triplex-forming abilities of the BNA modified oligonucleotides are also described.
