title: Synthesis and biological activity of cyclic ADP-carbocyclic-ribose analogs: structure-activity relationship and conformational analysis of N-1-carbocyclic-ribose moiety.
abstract: Several cyclic ADP-carbocyclic-ribose analogs 3-10 modified in the N-1-carbocyclic-ribose moiety were synthesized. Their Ca2+-releasing activity was estimated in sea urchin eggs to show that the 3"-deoxy analog 6 shows 5 times more potent activity than cADPcR, but the 2",3"-didieoxy-2",3"-unsunsaturated analog 3 has very weak activity. We also calculated their stable conformation and found that 3 and 6 were significantly different in their stable conformation.
