Wu, Ying published the artcileAxinellasins A-D, immunosuppressive cycloheptapeptide diastereomers, discovered via a precursor ion scanning-supercritical fluid chromatography strategy from the marine sponge Axinella species, SDS of cas: 71989-31-6, the publication is Organic Letters (2022), 24(3), 934-938, database is CAplus and MEDLINE.
The precursor ion scanning-supercritical fluid chromatog. (PI-SFC) method was applied to explore new methionine sulfoxide-containing cycloheptapeptides, axinellasins A-D (1-4), from the marine sponge Axinella sp. Their structures, including absolute configurations, were elucidated by detailed spectroscopic analyses and X-ray crystallog. The total synthesis of axinellasin D was completed via an Fmoc (Fmoc = 9-fluorenylmethoxycarbonyl) solid/solution-phase synthesis. Axinellasins A-D exhibited immunosuppressive effects via inhibition of T and B cell proliferation, and Axinellasin A and D showed better inhibitory activities than their corresponding diastereomers.
