Adenosine kinase (AK) catalyzes the phosphorylation of adenosine (Ado) to AMP by means of a kinetic mechanism in which the two substrates Ado and ATP bind the enzyme in a binary and/or ternary complex, with distinct protein conformations. Most of the desc

Synthesis of convolutamines and lutamides, new 2,4,6-tribromo-3-methoxyphenethylamine alkaloids isolated from Floridian marine bryozoan Amathia convoluta, was accomplished by a sequence of reactions starting from 3-hydroxyphenethylamines. Cytotoxities of the synthetic lutamides, convolutamines and their de-O-methyl derivatives were examined using drug-sensitive and -resistant P388 as well as KB cell lines. The bioassay suggests that the 2,4,6-tribromo-3-methoxyphenethylamine is an indispensable unit for detection of the activities. Additionally, a reversal of drug resistance by those alkaloids is recognized. Copyright (C) 2000 Elsevier Science Ltd.

A series of aryl phosphoglyceride (3, 19-61) and bis-aryl phosphate (67-135) antagonists of platelet activating factor (PAF) were prepared.A group of four bifunctional phosphorus reagents (5a-c and 7) were developed that allowed the preparation of these aryl phosphates in which the position of aromatic substitution can be varied.These compounds were examined for their ability to inhibit PAF-induced platelet aggregation of rabbit platelets.Selected compounds were also evaluated for their ability to displace PAF from its receptor on rabbit platelets.These in vitro data were compared to similar data obtained for a number of known PAF antagonists.The compounds were evaluated in vivo, in both the mouse and rabbit, for their ability to prevent death induced by a lethal challenge of PAF.The relationships between the biological activity and the nature, lipophilicity, and position of substituents of the aromatic rings were studied.Compound 105 (CL 184005) has been selected to undergo further development as a potential therapeutic agent for the treatment of septic shock in man.
INTRAMOLECULAR RADICAL COUPLING OF A PHENOLIC ENOLATE: OXIDATIVE FRAGMENTATION OF THE SPIRODIKETONE INTERMEDIATE

Ferricyanide oxidation of the dianion of the phenolic β-diketone 6b in basic conditions effects intramolecular radical coupling to form the spirocyclic diketone 7 which leads to the hydroxy tetralone 8 via an oxidative fragmentation process.
