Abstract
The invention relates to a method for preparing linear polymers having an amide end or having a star architecture comprising an amide core, by means of a ring opening using lactide and glycolide monomers or a lactide monomer ring in the presence of a catalyst, wherein the method includes the steps of: (i) reacting the excess monomer(s) with an initiator in a solvent, said initiator being selected from among an amine and an amino alcohol, given that the initiator has at least one primary or secondary amine function; (ii) adding a catalyst, said catalyst being a non-nucleophilic base and including at least one neutral sp2 nitrogen atom; and (iii) neutralizing the reaction mixture. Said novel method is particularly advantageous in that it can be easily monitored and enables better modulation of the polymers, and thus of the properties thereof, than the methods of the prior art. The invention also relates to novel polymers that are obtainable by means of said method.
Description
technical field [0001] The present invention relates to bridged spiro[2.4]heptyl derivatives of formula (I) and their use as medicaments. The invention also relates to related aspects comprising processes for the preparation of the compounds, pharmaceutical compositions comprising one or more compounds of formula (I), in particular their use as ALX receptor agonists. Background technique [0002] ALXR (alias lipoxin A4 receptor, FPRL1, FPR2; disclosed in WO2003 / 082314 as nucleotide sequence SEQ ID NO: 1 and amino acid sequence SEQ ID NO: 2) is a member of the G-protein coupled receptor family. ALXR was found to regulate calcium motility in response to high concentrations of the formylmethionine-leucylphenylalanine peptide. Furthermore, it was found that lipid metabolism, lipoxin A4 (LXA4), and its analogs bind ALXR with high affinity and increase arachidonic acid production and G protein activity in ALXR-transfected cells (Chiang et al. Pharmacol. Rev., 2006, 58, 463-487)....
