title: cADPR analogues: effect of an adenosine 2'- or 3'-methoxy group on conformation.
abstract: [structure: see text] The 2'-OMe-A (2) and 3'-OMe-A (3) analogues of the calcium release agent cADPR (1) were prepared and their solution structures studied by NMR spectroscopy. Compared to 1, 2 shows a shift in its A ring conformation and changes in its R ring N:S and gammat:gamma+ ratios, while 3 displays a significant change in the conformation of its A ring gamma-bond.
