Selective Type IV Phosphodiesterase Inhibitors as Antiasthmatic Agents. The Syntheses and Biological Activities of 3-(Cyclopentyloxy)-4-methoxybenzamides and Analogs
摘要:
The syntheses and biological activities of a number of benzamide derivatives, designed from rolipram, which are selective inhibitors of cyclic AMP-specific phosphodiesterase (PDE IV), are described. The effects of changes to the alkoxy groups, amide linkage, and benzamide N-phenyl ring on the inhibition of the cytosolic PDE IV from pig aorta have been investigated. As a result, some highly potent and selective PDE IV inhibitors have been identified. The most potent compounds have been further evaluated for their inhibitory potencies against PDE IV obtained from and superoxide O-2(-) generation from guinea pig eosinophils in vitro. Selected compounds have also been examined for their activities in inhibiting histamine-induced bronchospasm in anaesthetized guinea pigs. 3-(Cyclopentyloxy)-N-(3,5-dichloro-4-pyridyl)-4-methoxybenzamide (15j) showed exceptional potency in all tests and may have therapeutic potential in the treatment of asthma.

enhanced analgesic efficacy between solubleepoxidehydrolase (sEH) and phosphodiesterase 4 (PDE4) inhibitors, we designed, synthesized and characterized 21 novel sEH/PDE4 dual inhibitors. The best of these displayed good efficacy in in vitro assays. Further pharmacokinetic studies of a subset of four selected compounds led to the identification of a bioavailable dual inhibitor N-(4-methoxy-2-(tri
受先前发现的可溶性环氧化物水解酶 (sEH) 和磷酸二酯酶 4 (PDE4) 抑制剂增强镇痛功效的启发,我们设计、合成并表征了 21 种新型 sEH/PDE4 双重抑制剂。其中最好的在体外试验中显示出良好的功效。对四种选定化合物的子集的进一步药代动力学研究导致鉴定出生物可利用的双重抑制剂N -(4-甲氧基-2-(三氟甲基)苄基)-1-丙酰哌啶-4-甲酰胺 ( MPPA )。在脂多糖诱导的炎症性疼痛大鼠模型中,口服 3 mg/kg 后,血液中的MPPA迅速增加( T max = 30 分钟;C max = 460 nM),并减少炎症疼痛,且起效迅速,与血液水平相关4小时的时间过程。此外,MPPA不会改变患有炎性疼痛的大鼠的自我激励探索或对照大鼠的戒断潜伏期。

compounds which can bind to the TRFH domain of TRF2 and block the interactions between TRF2 and its associated proteins is crucial for elucidating the molecular mechanisms of these protein–protein interactions. Using a previously identified peptidic mimetic of ApolloTBM as a lead compound, we designed and synthesized a series of novel TRF2 inhibitors by non-peptidic modifications of the N-terminal residues
