hydrolase were observed with 3c and the 6'-(halohomovinyl)adenosine analogues. The order of inhibitory potency was I > Br > Cl > F and E > Z for the geometric isomers. AdoHcy hydrolase effected "hydrolysis" of the 6'-halogen from the (halohomovinyl)Ado compounds (to give the putative 6'-carboxaldehyde which underwent spontaneous decomposition) independently of its oxidative activity.
