[EN] LECTIN-TARGETING CONJUGATES [FR] CONJUGUÉS CIBLANT LA LECTINE
摘要:
The present invention relates to a conjugate comprising a ligand specifically binding to a bacterial lectin, a linker comprising a peptide cleavable by a bacterial protease, and an anti-bacterial therapeutic agent or imaging agent. It further relates to the conjugate or the pharmaceutical composition or diagnostic composition for use in medicine.

The present invention relates to fucose- and mannose-derived glycomimetics and their general use in prophylaxis or treatment of Pseudomonas aeruginosa infections including respiratory tract infections, urinary tract infections, nosocomial infections and chronic wound infections in a patient encompassing a patient suffering already from cystic fibrosis. Said glycomimetics are inhibitors of Pseudomonas aeruginosa lectin LecB.

can be exploited for targeted drug delivery. In this work, several fluoroquinolones were conjugated to lectin probes by cleavable peptide linkers to yield lectin-targeted prodrugs. Mechanistically, these conjugates therefore remain non-toxic in the systemic distribution and will be activated to kill only once they have accumulated at the infection site. The synthesized prodrugs proved stable in the
LecB, we designed and synthesized a set of fucosyl amides, sulfonamides, and thiourea derivatives. Then, we analyzed their binding to LecB in competitive and direct binding assays. We identified β-fucosyl amides as unprecedented high-affinity ligands in the two-digit nanomolar range. X-ray crystallography of one α- and one β-anomer of N-fucosyl amides in complex with LecB revealed the interactions responsible
