Tocopherol long chain fatty alcohols decrease the production of TNF-α and NO radicals by activated microglial cells
摘要:
The synthesis of a series of Tocopherol long chain Fatty Alcohols (TEA) and their biological activities on the modulation of microglial activation are described. Specifically, the 2-(12-hydroxy-dodecyl)-2,5,7,8-tetramethyl-chroman-6-ol, the TEA bearing 12 carbon atoms on the side chain (n = 12), shows the most potent inhibition of secretion on nitric oxide (NO) and tumour necrosis factor-alpha (TNF-alpha) by lipopolysaccharide (LPS)-activated microglia.

Kohamaic acid A is a potent DNA polymerase inhibitor isolated from the Okinawan marine sponge Ircinia sp. A series of structurally simplified analogs of kohamaic acid A were synthesized with the aim of evaluating structure-activity relationships.
