1. 3-Hydroxy-2-phenylcinchoninic acid (HPC) produced marked antipyresis in the fevered dog, rabbit and rat.
2. Seven derivatives of cinchoninic acid (those with a 3-OH or 2-Ph substituent) were found to have antipyretic activity in the yeast fevered rat. Of these, the most active was 3-hydroxy-2-phenylquinoline-4,8-dicarboxylic acid. Several compounds, including HPC, were considerably more active than salicylic acid or cinchophen.
