A new class of non-glycosidic and non-peptidic inhibitors of selectins with low molecular weight according to the general formula 1
is described, as well as methods for their production. These compounds represent a new class of non-toxic, in vivo anti-inflammatory effective inhibitors of selectins, and do not exhibit the disadvantages of the glycosidic inhibitor complexes, and are furthermore more potent in vitro, compared to the known drug bimosiamose. Furthermore, medicaments containing the compounds and their uses in the treatment of diseases are described.
efficient method for α-brominating lactones that affords α-bromolactones under mild conditions using tetraalkylammonium hydroxide (R4N+OH−) as a base was developed. Lactones are ring-opened with Br2 and a substoichiometric amount of PBr3, leading to good yields of the corresponding α-bromocarboxylic acids. Subsequent intramolecular cyclization over 1 h using a two-phase system (H2O/CHCl3) containing R4N+OH−
