Halophosphonate ATP analogues pp[CHBr]pA and p[CHBr]ppA synthesised from bromomethylenebisphosphonate and adenosine derivatives, proved to be effective competitive inhibitors of Ac-CoA-carboxylase (CE 6.4.1.2) from rat liver (Ki = 0,2 mM). The inhibitory effects of both analogues were reversible and higher than those of some other ATP analogues. Another enzyme, Ac-CoA-synthetase (CE 6.2.1.1), with a different mode of ATP-cleavage showed wider specificity to ATP-analogues than Ac-CoA-carboxylase.
