H. Morita et al., DICHOTOMIN-A, A NEW CYCLIC HEXAPEPTIDE FROM STELLARIA-DICHOTOMA L VARLANCEOLATA BGE, Bioorganic & medicinal chemistry letters, 5(20), 1995, pp. 2353-2356
A new cyclic hexapeptide, dichotomin A, showing cell growth inhibitory
activity, has been isolated from the roots of Stellaria dichotoma L.
var. lanceolata Bge. and the structure and solid state conformation we
re elucidated by extensive 2D NMR, chemical degradation and X-ray anal
ysis.
