One strategy encompasses synthesis of a series of compounds that inhibit the production of pyocyanin, a redox-active virulence factor produced by this pathogen. A related strategy encompasses synthesis of compounds that inhibit the two P. aeruginosa quorum-sensing receptors, LasR and RhlR, inhibit production of pyocyanin, and inhibit biofilm formation.
专利号:WO-2024256496-A1 优先权日:2023-06-14 标题 :[1,2,4]-triazolo[4,3-b]pyridazine derivatives useful as a medicament 发明人:ELIE JONATHAN; GEORGE PASCAL; MIEGE FRÉDÉRIC; MEIJER LAURENT 权利人:PERHA PHARMACEUTICALS 摘要:The present invention relates to a compound of formula (I) or any of its pharmaceutically acceptable salt. The present invention further relates to a synthesis process for manufacturing compound of formula (I) or any of its pharmaceutically acceptable salts, comprising at least a step of reacting a compound of formula (II) with an amine of formula (IV) NHR5R6 for example in a molar ratio ranging from 1 to 20 eq, with respect to the compound of formula (II), in an aprotic solvent or without solvent or else in a protic solvent.
