Synthesis and Biological Evaluation of d-Amino Acid Oxidase Inhibitors
摘要:
D-Amino acid oxidase (DAAO) catalyzes the oxidation of D-amino acids including D-serine, a full agonist at the glycine site of the NMDA receptor. A series of benzo[d]isoxazol-3-ol derivatives were synthesized and evaluated as DAAO inhibitors. Among them, 5-chlorobenzo[d]isoxazol-3-ol (CBIO) potently inhibited DAAO with an IC(50) in the submicromolar range. Oral administration of CBIO in conjunction with D-serine enhanced the plasma and brain levels of D-serine in rats compared to the oral administration Of D-serine alone.
Potent and selective aldo-keto reductase 1C3 (AKR1C3) inhibitors based on the benzoisoxazole moiety: application of a bioisosteric scaffold hopping approach to flufenamic acid
focused around an acidic hydroxybenzoisoxazole moiety, which was rationalised to mimic the benzoic acid role in the flufenamic scaffold. Through iterative rounds of drug design, synthesis and biologicalevaluation, several compounds were discovered to target AKR1C3 in a selective manner. The most promising compound of series (6) was found to be highly selective (up to 450-fold) for AKR1C3 over the 1C2
