Synthesis of labelled oxylipins: leukotriene A4 and 8-epi-prostaglandin F2α
摘要:
Tritiated leukotriene A(4) and 8-epi-prostaglandin F-2 alpha methyl esters were prepared from the corresponding acetylenic precursors by selective reduction with tritium gas to provide a probe for the metabolite identification of these oxylipins. Partially deactivated Pd-catalysts were prepared from commercial products and their composition was optimized to achieve the better selectivity. A micro-method for the saponification of labelled oxylipins methyl esters was used.
Total synthesis of 15(RS)-5,6-dehydro-8-epi-PGF2α methyl ester by a biomimetic process
摘要:
The first total synthesis of 15(RS)-5,6-dehydro-8-epi-PGF(2 alpha) methyl ester 1 with high stereoselectivity and good yield, is described using D-glucose as starting material. This novel isoprostane is a potent precursor of labelled (deutered and/or tritiated) 8-epi-PGF(2 alpha), an useful tool for biological studies. (C) 1997 Published by Elsevier Science Ltd.
