Potent and orally bioavailable zwitterion GnRH antagonists with low CYP3A4 inhibitory activity
摘要:
Incorporation of a carboxylic acid into a series of uracil derivatives as hGnRH-R antagonists resulted in a significant reduction of CYP3A4 inhibitory activity. Highly potent hGnRH antagonists with low CYP3A4 inhibitory liability, such as 8a and 8d, were identified. Thus, 8a had a K(i) of 2.2 nM at GnRH-R and an IC(50) of 36 mu M at CYP3A4.

Uracils as potent antagonists of the human gonadotropin-releasing hormone receptor without atropisomers
摘要:
Uracil derivatives were designed and synthesized to avoid atropisomers observed in the 6-methyluracils as antagonists of the human GnRH receptor. Optimization at the 1- and 5-positions of the uracil resulted in potent compounds such as 24 (K-i = 0.45 nM). (c) 2005 Elsevier Ltd. All rights reserved.
