  Specific Inhibitors of Puromycin-Sensitive Aminopeptidase with a 3-(Halogenated Phenyl)-2,4(1H,3H)-quinazolinedione Skeleton

  摘要：

  Specific puromycin-sensitive aminopeptidase (PSA) inhibitors with a 3-(halogenated phenyl)-2,4(1H,3H)-quinazolinedione skeleton were prepared and their structure-activity relationships were investigated. The nature (F, Cl or Br), number and position(s) of the halogen atom(s) introduced into the 3-phenyl group were concluded to be critical determinants of the inhibitory activity.

  Structural optimization of a CXCR2-directed antagonist that indirectly inhibits γ-secretase and reduces Aβ

  摘要：

  Amyloid beta(A beta), a key molecule in the pathogenesis of Alzheimer's disease (AD), is derived from the amyloid precursor protein (APP) by sequential proteolysis via beta- and gamma-secretases. Because of their role in generation of A beta, these enzymes have emerged as important therapeutic targets for AD. In the case of gamma-secretase, progress has been made towards designing potent inhibitors with suitable pharmacological profiles. Direct gamma-secretase inhibitors are being evaluated in clinical trials and new strategies are being explored to block gamma-secretase activity indirectly as well. In this regard, we have previously reported an indirect regulation of gamma-secretase through antagonism of CXCR2, a G-protein coupled receptor (GPCR). We demonstrated that N-(2-hydroxy-4-nitrophenyl)-N'-(2-bromophenyl)urea (SB225002), a selective inhibitor of CXCR2 also plays a role in an indirect inhibition of gamma-secretase. Furthermore, we reported a similar to 5-fold difference in the selective inhibition of APP versus Notch processing via gamma-secretase following treatment with SB225002. Herein we describe the synthesis and optimization of SB225002. By determination of the structure-activity relationship (SAR), we derived small molecules that inhibit A beta 40 production with IC(50) values in the sub-micromolar range in a cell-based assay and also validated the potential of CXCR2 as a new target for therapeutic intervention in AD.

  We have synthesized a series of N-phenyl-N'-aralkyl and N-phenyl-N'-(1-phenylcycloalkyl)ureas as inhibitors of acyl-CoA:cholesterol acyltransferase (ACAT). This intracellular enzyme is thought to be responsible for the esterification of dietary cholesterol; hence inhibition of this enzyme could reduce diet-induced hypercholesterolemia. For this series of compounds, the in vitro ACAT inhibitory activity

  我们合成了一系列的N-苯基-N'-芳烷基和N-苯基-N'-（1-苯基环烷基）脲作为酰基辅酶A：胆固醇酰基转移酶（ACAT）的抑制剂。人们认为这种细胞内酶负责饮食中胆固醇的酯化。因此抑制这种酶可以减少饮食引起的高胆固醇血症。对于这一系列化合物，通过增加苯环上2,6-取代基的体积来提高体外ACAT抑制活性。此外，我们发现芳环的间距对于ACAT抑制活性至关重要。离必需的2,6-二异丙基苯基部分5个原子的苯环对于体外活性而言是最佳的。N'-苯基部分被α取代增强了体外效能。就苯基环烷基脲而言，ACAT抑制活性与环烷基环的大小无关。从该系列类似物中，发现在高胆固醇血症动物模型中以50 mg / kg的饮食施用时，具有出色的体外抑制ACAT效力的化合物25在体内可使血浆胆固醇降低73％。在此模型中，化合物25依赖于降低血浆胆固醇剂量，并且与Lederle ACAT抑制剂CL 277082一样有效。

  acyl-coenzyme A:cholesterol acyltransferase (ACAT) in vitro and cholesterol lowering in vivo, systematic study of bioisosteric replacements for the amide bond in our previously identified series of fatty acid anilide ACAT inhibitors was undertaken. Only replacement of amide bonds with isosterases having both hydrogen bond donor and acceptor functionalities yielded compounds retaining ACAT inhibitory activity
