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.
