Optimization of Novel Antagonists to the Neurokinin-3 Receptor for the Treatment of Sex-Hormone Disorders (Part II)
摘要:
Further lead optimization on N-acyl-triazolopiperazine antagonists to the neurokinin-3 receptor (NK3R) based on the concurrent improvement in bioactivity and ligand lipophilic efficiency (LLE) is reported. Overall, compound 3 (LLE > 6) emerged as the most efficacious in castrated rat and monkey to lower plasma LH, and it displayed the best off-target safety profile that led to its clinical candidate nomination for the treatment of sex-hormone disorders.
The present invention relates to deuterated fezolinetant (R)-(4-fluorophenyl)-(8-methyl-3-(3-(methyl-d3)-1,2,4-thiadiazol-5-yl)-5,6-dihydro-[1,2,4]trizolo[4,3-a]pyrazin-7(8H)-yl)methanone, or a pharmaceutically acceptable solvate thereof, as NK-3 antagonist.
