Synthesis of 9,11-Ethano-13,15-isoxazolinoprostanoids, PGH Analogs
摘要:
The 1,3-dipolar addition to terminal alkenes of nitrile oxides generated from nitromethylene derivatives of bicycloheptane provided 9,11-ethano-13,15-isoxazolinoprostanoids with alkyl, phenyl, or additional heterocyclic fragment in the omega-chain.

New 9,11-ethano analogs of prostaglandin endoperoxides containing a sulfur atom in position 13 were synthesized by nucleophilic addition of thiols at the polarized double bond of 2-acylbicyclo[2.2.1]hept-2-enes. Physicochemical properties and biological activity of the products were studied.

Novel 9,11-ethano analogues of prostaglandin endoperoxides with a nitrogen in position 13 were synthesized. H-1 NMR spectra of the obtained compounds were studied. All prostanoids administered perorally at doses of 2.5-10.0 mug kg(-1) had specific dose-dependent effects on the B-cellular immunity estimated under in vivo conditions on the model of the B-cellular immune response. In terms of the direction of their activities, eight of the studied compounds were found to be immunostimulators, whereas other three compounds displayed immunosuppressing effect. Two of the compounds increased the amount of antibody-forming cells (AFC) per 10(6) spleen cells by 1.9 times in comparison with the respective parameter of control group. (C) 2004 Elsevier SAS.
