Screening a series of 4-anilinoquinolines and 4-anilinoquinazolines enabled identification of potent novel inhibitors of dengue virus (DENV). Preparation of focused 4-anilinoquinoline/quinazoline scaffold arrays led to the identification of a series of high potency 6-substituted bromine and iodine derivatives. The most potent compound 6-iodo-4-((3,4,5-trimethoxyphenyl)amino)quinoline-3-carbonitrile (47) inhibited DENV infection with an EC50 = 79 nM. Crucially, these compounds showed very limited toxicity with CC(50 )values > 10 mu M in almost all cases. This new promising series provides an anchor point for further development to optimize compound properties.
