摘要

Chemical study of the CH2Cl2−MeOH (1:1) extract from the sponge sp. collected in Mayotte highlighted three new long-chain highly oxygenated polyacetylenes, osirisynes G-I ( – ) together with the known osirisynes A ( ), B ( ), and E ( ). Their structures were elucidated by 1D and 2D NMR spectra and HRESIMS and MS/MS data. All compounds were evaluated on catalase and sirtuin 1 activation and on CDK7, proteasome, Fyn kinase, tyrosinase, and elastase inhibition. Five compounds ( ; – ) inhibited proteasome kinase and two compounds ( – ) inhibited CDK7 and Fyn kinase. Osirisyne B ( ) was the most active compound with IC on FYNB kinase, CDK7 kinase, and proteasome inhibition of 18.44 µM, 9.13 µM, and 0.26 µM, respectively.
