Phorbasterones A-D, cytotoxic nor-ring A steroids from the sponge Phorbas amaranthus.
The sponge Phorbas amaranthus from Florida contains the new ring A-contracted steroids, phorbasterones A-D, and the known anthosterones A and B. The structures of phorbasterones A-D were determined by interpretation of their spectroscopic data. Phorbasterones show moderate cytotoxicity against HCT-116 tumor cells.
متن کاملSynthesis and Bioactivity of a Cyclopolypeptide from Caribbean Marine Sponge
Synthesis of a natural proline-rich cyclopolypeptide - rolloamide A [8] was carried out by coupling of tri- and tetrapeptide units Boc-Phe-Pro-Val-OMe and Boc-Pro-Leu-Pro-Ile-OMe after proper deprotection at carboxyl and amino terminals using carbodiimide chemistry in alkaline environment followed by cyclization of linear heptapeptide segment in the presence of base. The structure of synthesize...

متن کاملELOVL1 production of C24 acyl-CoAs is linked to C24 sphingolipid synthesis.
Very long-chain fatty acids (VLCFAs) exert a variety of cellular functions and are associated with numerous diseases. However, the precise pathway behind their elongation has remained elusive. Moreover, few regulatory mechanisms for VLCFAs synthesis have been identified. Elongases catalyze the first of four steps in the VLCFA elongation cycle; mammals have seven elongases (ELOVL1-7). In the pre...
متن کاملA shift in sphingolipid composition from C24 to C16 increases susceptibility to apoptosis in HeLa cells.
Sphingolipids, major lipid components of the eukaryotic plasma membrane, have a variety of physiological functions and have been associated with many diseases. They have also been implicated in apoptosis. Sphingolipids are heterogeneous in their acyl chain length, with long-chain (C16) and very long-chain (C24) sphingolipids being predominant in most mammalian tissues. We demonstrate that knock...
