Synthesis and biological evaluation of γ-aminophosphonates as potent, subtype-selective sphingosine 1-phosphate receptor agonists and antagonists
摘要:
The synthesis of N-arylamide phosphonates and related arylether and arylamine analogues provided potent, subtype-selective agonists and antagonists of the five known sphingosine I-phosphate (SIP) receptors (S1P(1-5)). To this end, the syntheses of phosphoserine mimetics-selectively protected and optically active phosphonoserines-are described. In vitro binding assays showed that the implementation of phosphonates as phosphate mimetics provided compounds with similar receptor binding affinities as compared to their phosphate precursors. meta-substituted arylamide phosphonates were discovered to be antagonists of the S1P(1) and S1P(3) receptors. When administered to mice, an antagonist blocked the lymphopenia evoked by a SIP receptor agonist and caused capillary leakage in both lung and kidney. (c) 2006 Elsevier Ltd. All rights reserved.

Novel Easily Recyclable Bifunctional Phosphonic Acid Carrying Tripeptides for the Stereoselective Michael Addition of Aldehydes with Nitroalkenes
A novelbifunctional organocatalyst library combining both aminocatalysis and phosphonicacid activation was used for the first time as an efficient tool for the stereoselectiveMichaeladdition of aldehydes with several aromatic nitroalkenes with good selectivities up to 95:5 dr and 93:7 er. Due to their high water solubility, the catalysts were easilyrecyclable and could be reused over several cycles
