Abstract:Cyclo-L-prolyl-glycyl was isolated from Diodon novemaculatus (Bleeker) and characterised by X-ray diffraction analysis. C7H10N2O2, MW 154.17, space group P212121, a = 5.869(1), b = 9.674(2), c = 13.076(3) A,V = 742.4(2) A3, Z = 4, D = 1.379 g cm-3, μ(MoKα) = 0.96 cm-1, final R =0.034 and Rg = 0.047 for 939 observed data. Intermolecular N-H...0hydrogen bonds link the molecules into infinite zigzag chains parallel tothe b axis.
