Enzymatic Synthesis of 15-Hydroperoxythromboxane
نویسنده
چکیده
Partially purified thromboxane synthase from human platelets converted prostaglandin Gz to two products. These were transformed to 12-hydroxy-5,8,10heptadecatrienoic acid and thromboxane B2 by stannous chloride reduction and to 12-keto-5,8,10-heptadecatrienoic acid and 15-ketothromboxane Bz by lead tetraacetate dehydration. Trapping with methanol after short incubations of substrate with enzyme and reduction by stannous chloride yielded 11-0-methylthromboxane B2. Based on these results, the enzymatically formed products were identified as 12-hydroperoxy-5,8,10-heptadecatrienoic acid and 15-hydroperoxythromboxane A2.

The reaction of furylacrylic acid with cyclopentadiene in toluene gave the expected Diels-Alder endo-and exo-adductsin -1 : 1 ratio. The adducts were separated by iodolactonization method to provide 3-endo-(2'-furyl) bicyclo 12.2.11 hept-5-ene- 2-exo-carboxylic acid and 3-exo-(2'-fury1)bicyclo 12.2.11 hept-5-ene-2-endocarboxylic acid. Esterification of these acids by MeI / HMPA gave the exp...
متن کاملEnzymatic Synthesis of Sucrose-6-acetate by a Novel Immobilized Fructosyltransferase From Aspergillus sp. GX-0010
Background: Sucralose is an ideal food sweetener and sucrose-6-acetate (s-6-a) is a key intermediate for synthesis of sucralose. Synthesis of s-6-a was studied by free fructosyltransferase (FTase) from Aspergillus oryzae. Because of the limitations of free enzyme in stability and reusability, a FTase obtained from the new isolated Aspergillus sp. GX-0010 was immobilized and inv...
