  and synthesized based on the known proteasome inhibitor PI-1840. Most of them showed significant inhibition against the β5c subunit of human 20S proteasome, and five of them exhibited IC50 values at the sub-micromolar level, which were comparable to or even more potent than PI-1840. The most active two (1c and 1d) showed IC50 values of 0.12 and 0.18 μM against the β5c subunit, respectively, while they

  基于已知的蛋白酶体抑制剂PI-1840设计并合成了三十种新型三芳基化合物。它们中的大多数显示出对人20S蛋白酶体β5c亚基的显着抑制作用，并且其中五种在亚微摩尔水平显示出IC 50值，与PI-1840相当甚至更高。最活跃的两个（1c和1d）对β5c亚基的IC 50值分别为0.12和0.18μM，而对β2c，β1c和β5i亚基没有明显的抑制作用。分子对接为亚基选择性提供了有益的线索。本文鉴定的有效和亚基选择性蛋白酶体抑制剂代表了用于进一步分子优化的新化学模板。

  Focused library synthesis and medicinal chemistry on an oxadiazole-isopropylamide core proteasome inhibitor provided the lead compound that strongly inhibits CT-L activity. Structure activity relationship studies indicate the amide moiety and two phenyl rings are sensitive toward synthetic modifications. Only para-substitution in the A-ring was important to maintain potent CT-L inhibitory activity. Hydrophobic residues in the A-ring's para-position and meta-pyridyl group at the B-ring significantly improved inhibition. The meta-pyridyl moiety improved cell permeability. The length of the aliphatic chain at the para position of the A-ring is critical with propyl yielding the most potent inhibitor, whereas shorter (i.e. ethyl, methyl or hydrogen) or longer (i.e. butyl, propyl and hexyl) chains demonstrating progressively less potency. Introduction of a stereogenic center next to the ether moiety (i.e. substitution of one of the hydrogens by methyl) demonstrated chiral discrimination in proteasome CT-L activity inhibition (the S-enantiomer was 35-40 fold more potent than the R-enantiomer).

  Using Entinostat as a lead compound, 2-aminobenzamide and hydroxamate derivatives have been designed and synthesized. The entire target compounds were investigated for their in vitro anti-proliferative activities using the MTT-based assay against five human cancer cell lines including U937, A549, NCI-H661, MDA-MB-231 and HCT116. 2-Aminobenzamide series of compounds (10a-10j) demonstrated the most significant inhibition against human acute monocytic myeloid leukemia cell line U937, but no or poor activities against two human lung cancer cell lines. Furthermore, the target compounds were screened for their inhibitory activities against HDAC 1, 2, and 8. 2-Aminobenzamide derivatives (10) manifested a higher selectivity for HDAC 1 over HDAC 2, but were not active against HDAC 8. In contrast, most hydroxamate derivatives (11) inhibit HDAC 8 with lower IC50 values than SAHA and Entinostat. Docking study with selected compounds 10f and ha revealed that the compounds might bind tightly to the binding pockets in HDAC 2 and HDAC 8, respectively. The results suggest that they may be promising lead compounds for the development of novel anti-tumor drug potentially via inhibiting HDACs. (C) 2015 Elsevier Masson SAS. All rights reserved.
