SYNTHESIS AND IMMUNOMODULATORY ACTIVITES OF NEW 5-HYDRAZINO-3-METHYL-4-ISOTHIAZOLECARBOXYLIC ACID ETHYL ESTERS

Several new derivatives of 5-hydrazino-3-methyl-4-isothiazolecarboxylic ethyl esters were synthesized. Using 4-aminoacetophenone, the hydrazine group was transformed in position 5 in the hydrazone which reacted with the isocyanates, aldehydes and sugars. Thirteen newly synthesized compounds were tested for their ability to affects the immunological response in vitro in several rodent models. The immunoregulatory properties of the compounds were, differential and dose-dependent, The strongest activity was exhibited by 5-{N’-[1-4}-4-[3-(-methoxyphenyl)-ureido]-phenylethylidene]-hydrazino}-3-methyl-4-isothiazolecarboxylic acid ethyl ester (compound 3a). The compound strongly inhibited the secondary, humoral immune response to sheep erythrocytes and the proliferative response of mouse splenocytes to concanavalin A and pokeweed mitogen. The immunotropic activities of the new isothiazole derivatives and potential application of the compounds in therapy are discussed.

Introduction of sulfur atoms into trifluoromethylated alkenyl sulfones and chlorides using a reactive sulfur-graphite electrode

A substrate, 2-(4-biphenylyl)-4,4,4-trifluoro-3-phenylsulfonyl-2-butenenitrile (1a) afforded a coupling compound bridged with a nitrogen atom of isothiazole and 1,2-dithiolane skeleton (2). 1-(4-Biphenylyl)-3,3,3-trifluoro-2-phenylsulfonylpropene (1b) without a cyano group gave a complex oligomeric compound (3) without the elimination of the phenylsulfonyl group. 2- (4-Biphenylyl)-3-chloro-4,4,4-trifluoro-2 butenenitrile (1c) having a chloro group as a leaving group gave 2,4-di (4-biphenylyl)-2,4-dicyano-1,5-bis (trifluoromethyl)-3,6-dithiabicyclo[3.1.0]hexane (4) and 2-(4-biphenylyl)-4,4,4-trifluoro-2-butenenitrile (5).

The formation of such sulfur-containing organofluorine compounds except for the oligomeric compound 3 is characterized as the addition of polysulfide anion(s) produced by electroreduction of elemental sulfur. followed by the elimination of the phenylsulfonyl or the chloro group.

EDA Complexes of N-halosaccharins with N- and O-donor ligands

A series of EDA complexes of N-iodosaccharin (NISac) and N-bromosaccharin (NBSac) with nitrogen and oxygen electron-pair donors, NISac center dot H2O, NISac center dot THF, NISac center dot Py, NISac(2)center dot Pyz and NBSac(2)center dot Pyz, was prepared and examined by X-ray diffraction and NMR. The complexes are relatively stable, crystalline compounds with the ligand bound to the halogen atom in a nearly linear arrangement N-halogen-ligand. The halogen-ligand distances are inversely proportional to the donor ability of the ligand. The interactions between ligand and halogen are stronger for iodine than bromine. The X-ray structure analysis has shown that for some compounds the N-X bond in the halosaccharin moiety is not coplanar with the isothiazole ring, and the quantum-chemical calculations demonstrate a high flexibility of the corresponding angle. Complexes were modelled also by DFT calculations using B3LYP and MPW1K functionals. A better fit of the computed geometry was obtained by the geometry optimization in a polar solvent continuum than in vacuum.
