Antineoplastic Agents. 485. Isolation and Structure of Cribrostatin 6, a Dark Blue Cancer Cell Growth Inhibitor from the Marine Sponge <i>Cribrochalina </i>sp.^,1a

Abstract excerpt

Cribrostatin 6, a dark blue cancer cell growth inhibiting (P388 ED(50) 0.3 microg/mL) constituent of the Republic of Maldives marine sponge Cribrochalina sp., has been assigned structure 3 on the basis of a combination of HRMS, high-field (500 MHz, HMBC, and GOESY experiments) (15)N, (1)H, and (13)C NMR, and X-ray crystal structure analyses. Cribrostatin 6 also was found to inhibit the growth of a number of...
