| 1 | Studies on the chemical constituents of the South China Sea sponge Phacellia fusca显示文摘Three pyrrololactam alkaloids have been isolated from the marine sponge Phacellia fuscaSchmidt collected from the South China Sea,and their structures were determined as 1—3,on thegrounds of spectral data.This is the first report of these compounds from this sponge.The structureof 1 was confirmed by X-ray analysis. | ZENG,Long-Mei FU,Xiong SU,Jing-Yu Department of Chemistry,Zhongshan University,Guangzhou 510275De GUZMAN,Florecita SCHMITZ,Francis J HOSSAIN,M.Bilayet van der HELM,Dick Department of Chemistry and Biochemistry,University of Oklahoma,Norman,OK73019-0370,U.S.A. | 1991 | Chinese Journal of Chemistry1991，9，2： | 1 |

| 3 | A Novel Pyrrololactam Alkaloid from the South China Sea Sponge Phacellia Fusca Schmidt显示文摘Pyrrololactam type of alkaloids was found in many marine sponges which belong to the family Axinellidae. In the course of our systematic research for bioactive substances in marine organisms, we studied the sponge Phacellia fusca Schmidt which also belongs to the family Axinelldae. From the chloroform-soluble fraction, ten A-nor-sterols were isolated and identified, while from the water-soluble portion, three known pyrrololactam alkaloids and a new pyrrololactam alkaloid, which was named fuscin, were obtained. The present paper contains the isolation and structure determination of fuscin (1). | Florecita De Guzman Francis J. Schmitz M.
