Acylcyclohexanedione derivatives as potential in vivo sequential inhibitors of 4-hydroxyphenylpyruvate dioxygenase and GA20 3β-hydroxylase
摘要:
Acylcyclohexanedione derivatives have been designed, synthesized, and evaluated for in vitro inhibition activity against the enzyme 4-hydroxyphenylpyruvate dioxygenase (4-HPPD). The biological data demonstrated that 7 is a potent inhibitor of 4-HPPD with an IC50 value of 40 nM. After metabolism, compound 7 has the potential to become a potent inhibitor of a second enzyme, GA(20) 3beta-hydroxylase. (C) 2003 Elsevier Science Ltd. All rights reserved.

Various 3-cyclopropanecarbonyloxy-2-cyclohexen-1-one 1 derivatives have been synthesized and tested as inhibitors of 4-hydroxyphenylpyruvate dioxygenase (4-HPPD) from pig liver. The inhibition results indicated that well-positioned dicarbonyl groups as well as the cyclopropyl group of 1 were essential for potent inhibition. Substitution at the 2-position of the ring system has a significant effect
