A New Diketopiperazine from the Marine Sponge Callyspongia Species
Chemical investigation of the sponge Callyspongia sp. from the South China Sea afforded one new diketopiperazine, cyclo-(R-Pro-6-hydroxyl-S-Ile) (1), along with six known diketopiperazines: staphyloamide A (2), cyclo(S-Pro-S-Phe) (3), cyclo-(R-Pro-R-Phe) (4), cyclo-(S-Pro-R-Leu) (5), cyclo-(S-Pro-R-Ala) (6), cyclo(R-Tyr-R-Phe) (7), and three known tryptophan-derived alkaloids: C 2 -α-D-mannosyl...
متن کاملBiosurfactant production from marine bacteria associated with sponge Callyspongia diffusa
Marine-derived biosurfactants have gained significant attention due to their structural and functional diversity. Biosurfactant production was performed using bacteria associated with Callyspongia diffusa, a marine sponge inhabiting the southern coast of India. A total of 101 sponge-associated bacteria were isolated on different media, of which 29 isolates showed positive result for biosurfacta...
متن کاملStudy of L-Asparaginase Production by Streptomyces noursei MTCC 10469, Isolated from Marine Sponge Callyspongia diffusa
L-asparaginase is an anti-neoplastic agent used in the chemotherapy of lymphoblastic leukaemia. The present work deals with production of extra-cellular Lasparaginase from marine actinomycetes, using submerged fermentation. Marine actinomycete Streptomyces associated with marine spongeCallyspongia diffusa was isolated using specific ISP medium. Sponge-associated Streptomyces was character...
متن کاملNovel spiciferone derivatives from the fungus Drechslera hawaiiensis isolated from the marine sponge Callyspongia aerizusa.
From the marine sponge Callyspongia aerizusa collected from the Sea of Bali, Indonesia, fungal isolates of Drechslera hawaiiensis were obtained. Culture filtrates of the fungus yielded four spiciferone derivatives which include spiciferone A (1) and B (2), and two other novel derivatives including spiciferol A (3) which is an alcohol congener of spiciferone A (1) and compound 4 which is an mono...
متن کاملA new 1,4-diazepine from South China Sea marine sponge Callyspongia species.
A new 1,4-diazepine, callysponine (1), was isolated from a South China Sea Callyspongia sp. marine sponge, together with four known proline-based diketopiperazines: cyclo-(S-Pro-R-Leu) (2), cyclo-(S-Pro-R-Val) (3), cyclo-(S-Pro-R-Ala) (4), andcyclo-(S-Pro-R-Tyr) (5). The new structure was determined on the basis of NMR and MS analysis, and the absolute stereochemistry was defined by NOESY spect...
