  Discovery of 3-aryl-5-aryl-1,2,4-oxadiazoles as a new series of apoptosis inducers. 2. Identification of more aqueous soluble analogs as potential anticancer agents

  摘要：

  As a continuation of our efforts to discover and develop the 3-aryl-5-aryl-1,2,4-oxadiazole series of apoptosis inducers as potential anticancer agents, we explored substitutions at the 2-and 3-positions of the 3-aryl group to improve the aqueous solubility properties and identify development candidates. A small substitution such as methyl or hydroxymethyl at the 2-position was well tolerated. This modification, in combination with a 3-substituted furan ring as the 5-aryl group, resulted in 4g and 4h, which have improved solubility properties. Compound 4g was found to have good in vivo efficacy in animal studies via intravenous administration. (C) 2009 Elsevier Ltd. All rights reserved.

  Discovery and Structure−Activity Relationship of 3-Aryl-5-aryl-1,2,4-oxadiazoles as a New Series of Apoptosis Inducers and Potential Anticancer Agents

  摘要：

  We have identified 5-(3-chlorothiophen-2-yl)-3-(4-trifluoromethylphenyl)-1,2,4-oxadiazole (1d) as a novel apoptosis inducer through our caspase- and cell-based high-throughput screening assay. Compound 1d has good activity against several breast and colorectal cancer cell lines but is inactive against several other cancer cell lines. In a flow cytometry assay, treatment of T47D cells with 1d resulted in arrest of cells in the G, phase, followed by induction of apoptosis. SAR studies of 1d showed that the 3-phenyl group can be replaced by a pyridyl group, and a substituted five-member ring in the 5-position is important for activity. 5-(3-Chlorothiophen-2-yl)-3-(5-chloropyridin-2-yl)-1,2,4-oxadiazole (41) has been found to have in vivo activity in a MX-1 tumor model. Using a photoaffinity agent, the molecular target has been identified as TIP47, an IGF II receptor binding protein. Therefore, our cell-based chemical genetics approach for the discovery of apoptosis inducers can identify potential anticancer agents as well as their molecular targets.
