THE FIRST SYNTHESIS OF AN A-RING FUSED STEROIDAL ISOTHIAZOLE

A simple and efficient route to A-ring fused steroidal isothiazoles was developed. The key step involves C-S bond formation via substitution of a vinyl triflate at C-3.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 26040-51-7 is helpful to your research. Name: Bis(2-ethylhexyl) 3,4,5,6-tetrabromophthalate.

Synthesis and Structure of Esterification Products of 6-aryl-1,2,3,6,7,7a-hexahydro-3a,6-epoxyisoindole-7-carboxylic Acids

It was found that the reaction of 5-arylfurfurilamines with maleic anhydride leads to the formation of 6-aryl-3a,6-epoxyisoindole-7-carboxylic acids (the cyclic form), which in solution are in dynamic equilibrium with N-furfurylmaleinamides (the open form). During the esterification of these tautomeric mixtures with methanol in the presence of a catalytic amount of sulfuric acid, methyl esters of 5-aryl-7a-hydroxy-7-methoxy-3-oxo-2,3,3a,4,7,7a-hexahydro-1H-isoindole-4-carboxylic acids, unexpected cleavage products of the 3a,6-oxo bridge of the cyclic form, are formed diastereospecifically. The structure of the obtained products was confirmed by X-ray structural analysis.

Synthesis of new 3-methylthio-5-aryl-4-isothiazolecarbonitriles with broad antiviral spectrum

The isothiazole derivative 3-methylthio-5-(4-OBn-phenyl)-4-isothiazolecarbonitrile, coded IS-50, which in previous studies had exhibited a broad antipicornavirus spectrum of action, was selected as the model for the synthesis of a new series of 3-methylthio-5-aryl-4-isothiazolecarbonitriles. These compounds were prepared in good yield (from 66 to 82%) by alkylation of 3-methylthio-5-(4-hydroxyphenyl)-4-isothiazolecarbonitrile with suitable bromides in the presence of acetone; only the 4-cyanophenoxy derivatives were obtained in a yield of less than 30%. All the compounds were screened against a panel of 17 representative human rhinovirus (HRV) serotypes belonging to both A and B groups, enteroviruses polio 1, ECHO 9 and Coxsackie B1, cardiovirus EMC, measles virus, and herpes simplex virus type I (HSV-1). Our results demonstrate that HRV 86 (group A) and HRVs 39 and 89 (group B) are the rhinovirus serotypes more susceptible to the action of these compounds. Isothiazole derivatives with a longer intermediate alkyl chain exhibited good activity against polio 1 and ECHO 9. The compound bearing a butyl group between the two phenoxy rings showed the lowest IC50 against Coxsackie B1 and measles viruses. No activity against HSV-1 was detected with any of the compounds screened. (C) 2002 Published by Elsevier Science B.V.

Isothiazole dioxides: Synthesis and inhibition of Trypanosoma brucei protein farnesyltransferase

A series of isothiazole dioxides was synthesized and evaluated as inhibitors of protein farnesyltransferase from the parasite that causes African sleeping sickness (Trypanosoma brucei). The most potent compound in the series inhibited the parasite enzyme with an IC50 of 2 muM and blocked the growth of the bloodstream parasite in vitro with an ED50 of 10 muM. The same compound inhibited rat protein farnesyltransferase and protein geranylgeranyltransferase type I only at much higher concentration. (C) 2002 Elsevier Science Ltd. All rights reserved.
