Flexible analogues of WAY-267,464: Synthesis and pharmacology at the human oxytocin and vasopressin 1 a receptors
摘要:
A previously identified, non-peptidic oxytocin (OT) receptor agonist WAY-267,464 (1) and nine novel derivatives (3, 4a-7a, 4b-7b) were synthesised and evaluated in vitro with the aim of systematically exploring hydrogen bonding interactions and ligand flexibility. All analogues were subjected to competition radioligand binding assays at human oxytocin (OT) and arginine vasopressin 1a (V-1a) receptors. Physiological activity was determined using whole cell IP1 accumulation assays. Under these conditions, WAY -267,464 had higher affinity for the V-1a receptor compared to the OT receptor (8.5x more selective) with poor functional selectivity (2x selective for OT receptor agonism over V-1a receptor antagonism). Methylation of the resorcinol moiety (3) reversed the OT receptor pharmacological profile, removing agonist activity and inducing antagonist activity, without altering V-1a receptor pharmacology. All flexible tethered derivatives removed OT receptor affinity and activity resulting in the generation of highly selective V-1a receptor ligands. (C) 2015 Elsevier Masson SAS. All rights reserved.

New polymethylene derivatives of nucleic bases with a beta-diketo function in the omega-position were obtained by alkylation of uracil, thymine, cytosine, hypoxanthine, adenine, and N(2)-isobutyryl guanine with 2-omega-chloroal-kanoyl)cyclohexanones. The physical and chemical characteristics of the compounds synthesized and their effect on the K562 and HCT116 tumor cell lines were studied.

New polymethylene derivatives of nucleic bases with β-diketo function in ω-position were prepared by alkylation of uracil, thymine, and cytosine. Their physicochemical properties and effect on the E. coli uridine and thimidine phosphorylases were studied.
