T. Kato et al., STYLOGUANIDINES, NEW CHITINASE INHIBITORS FROM THE MARINE SPONGE STYLOTELLA-AURANTIUM, Tetrahedron letters, 36(12), 1995, pp. 2133-2136
Three potent new chitinase inhibitors, styloguanidines 1, 2 and 3, wer
e isolated from the sponge. Stylotella aurantium collected from the Ya
p sea. Their structures were determined by spectral means. These were
a new type of inhibitor from natural sources and were proved to inhibi
t the moulting of cyprid larvae or barnacles.
