  Penasins A−E, Long-Chain Cytotoxic Sphingoid Bases, from a Marine Sponge Penares sp

  摘要：

  Five sphingoid bases, penasin A (1), penasin B (2), and a mixture of penasins C-E (3-5), were identified from a marine sponge Penares sp. as cytotoxic constituents. The structure of the common polar head part was assigned by analysis of the NMR data, whereas the structures of the long aliphatic chains including the locations of double bond(s) and a branched methyl group were determined by analysis of tandem FABMS and C-13 NMR data together with the GC-MS analysis of ozonolysis products. The absolute configuration of the headgroup was defined for the mixture of 3-5 by the modified Mosher method. Penasins exhibit moderate cytotoxicity against HeLa and P388 cells.

  A composition including one or more monomethyl ester compounds represented by the formula, R1 is a monomethyl branched C15 to C19 alkyl group and R2 is an unsubstituted C2 to C30 linear alkyl group. The composition has a viscosity (Kv100) from 1 cSt to 10 cSt at 100°C as determined by ASTM D445, a viscosity index (VI) from -100 to 300 as determined by ASTM D2270, a pour point from 0°C to -50°C as determined by ASTM D97, and a Noack volatility of no greater than 50 percent as determined by ASTM D5800. A process for producing the composition, a lubricating oil base stock and lubricating oil containing the composition, and a method for improving one or more of cold flow properties, thermal and oxidative stability, solubility and dispersancy of polar additives, deposit control and traction control in a lubricating oil by using as the lubricating oil a formulated oil containing the composition.
