Novel, potent, selective, and orally bioavailable human βII-tryptase inhibitors
摘要:
The synthesis of novel [1,2,4]oxadiazoles and their structure-activity relationship (SAR) for the inhibition of tryptase and related serine proteases is presented. Elaboration of the P'-side afforded potent, selective, and orally bioavailable tryptase inhibitors. (c) 2006 Elsevier Ltd. All rights reserved.
novel aldosereductase inhibitors, several O‐substituted hydroxyphenylacetic acidderivatives were investigated. The highest inhibitoryactivity was found for compounds 7b and 7c bearing a cyclohexylmethyl substituent. This result demonstrates that within these series, this moiety is a useful surrogate for the 4‐bromo‐2‐fluorobenzyl residue which can be often found in potent aldosereductase inhibitors
为了继续我们旨在制备新型醛糖还原酶抑制剂的工作,研究了几种 O 取代的羟基苯乙酸衍生物。发现带有环己基甲基取代基的化合物 7b 和 7c 的抑制活性最高。该结果表明,在这些系列中,该部分是 4-溴-2-氟苄基残基的有用替代物,该残基通常可在有效的醛糖还原酶抑制剂中找到。

Gamma-hydroxybutyric acid (GHB) is a drug of abuse, a therapeutic, and purportedly a neurotransmitter with a complex mechanism of action in vivo due to direct actions at GABA(B) as well as GHB receptors and because of its metabolism to GABA. Herein, we describe 3-ethers of 3-hydroxyphenylacetic acid, which have relatively high affinity at GHB sites, no significant affinity at GABA receptors, and would not be expected to be rapidly metabolized to GABAergic ligands. The selectivity of these compounds (UMB108, UMB109, and UMB 119) could prove to be useful for studying the biology of GHB receptors, free from GABAergic effects. (c) 2005 Elsevier Ltd.
