Synthesis and identification of unprecedented selective inhibitors of CK1ε
摘要:
A small and structure-biased library of enantiopure anti-beta-amino alcohols was prepared in a straightforward manner by a simplified version of the Reetz protocol. Antiproliferative activity testing against a panel of five human solid tumor cell lines gave GI(50) values in the range 1-20 mu M. The reverse screening by computational methods against 58 proteins involved in cancer pointed to kinases as possible therapeutic target candidates. The experimental determination of the interaction with 456 kinases indicated that the compounds behave as selective CK1 epsilon inhibitors. Our results demonstrate that the lead compound represents the first selective CK1 epsilon inhibitor with proven antiproliferative activity in cancer cell lines. (C) 2015 Elsevier Masson SAS.

The (L)-threo-N,N-dibenzyl sphingosine was prepared in two steps from the serinal derivative 1 by diastereoselective alkenylation with pentadec-l-enyl(ethyl)zinc and deblocking. (D)-erythro-N,N-Dibenzyl sphingosine was also prepared in two steps from 1 by a highly diastereoselective alkynylation with pentadecynyl magnesium bromide and subsequent stereoselective LAH reduction.
