Adenosine 5 -triphosphate chromium complexes

Kortenkamp A, O Brien P. 1991. Studies of the binding of chromium(III) complexes to phosphate groups of adenosine triphosphate. Carginogenesis 12 921-926. 

Chromium(III) forms stable complexes with adenosine-S -triphosphate.840,841,842 These are kinetically inert analogues of magnesium ATP complexes and may be used to study enzyme systems. The complexes prepared are chiral and may be distinguished in terms of chirality at the metal centre (198,199).843 The related complex of chromium(lll) with adenosine-5 -(l-thiodiphosphate) has been prepared the diastereoisomers were separated.844 The stereospecific synthesis of chromium(III) complexes of thiophosphates has been reported845 by the method outlined in equation (47), enabling the configuration of the thiophosphoryl centre to be determined. The availability of optically pure substrates will enable the stereospecificity of various enzyme systems to be investigated.845...
