6-Acylamino-2-aminoquinolines as Potent Melanin-Concentrating Hormone 1 Receptor Antagonists. Identification, Structure−Activity Relationship, and Investigation of Binding Mode
摘要:
Novel 6-acylamino-2-aminoquinoline melanin-concentrating hormone 1 receptor (MCHIR) antagonists were identified by sequential in silico screening with 3D pharmacophore models derived from a series of benzamide antagonists. The structure- activity relationship exploration by synthesis of analogues found structural demands around the western part of the compounds to be quite specific, whereas much structural freedom was found in the eastern part. Vvhile these compounds in general suffered from poor solubility properties, the 4-trifluoromethoxy-phenoxyacetamide western appendage provided a favorable combination of activity and solubility properties. The amine in the eastern appendage, originally required by the pharmacophore model and believed to interact with Asp123 in transmembrane 3 of MCH1R, could be removed without diminishing affinity or functional activity of the compounds. Docking studies suggested that the Asp123 interacts preferentially with the nitrogen of the central quinoline. Synthesis and testing of specific analogues supported our revised binding mode hypothesis.
Identification and optimization of novel 6-acylamino-2-aminoquinolines as potent Hsp90 C-terminal inhibitors
摘要:
In order to discover novel Hsp90 inhibitors targeting the C-terminal ATP binding pocket, a novobiocin derivative based ROCS model was constructed for virtual screening. Compound 13 was identified as the lead compound and then systematical structure activity relationship (SAR) study was conducted. These efforts led to compound 69, which exhibited potent anti-proliferative activities against MCF7 and SKBr3 breast cancer cell lines. In 4T1 mice breast cancer models, 69 exhibited potent tumor growth inhibition and anti-metastasis effect. Compound 69 as a potent antitumor agent targeting the Hsp90 C-terminal is worthy of further pre-clinical study. (C) 2017 Published by Elsevier Masson SAS.
