Addressing species specific metabolism and solubility issues in a quinoline series of oral PDE4 inhibitors
Species specific conversion of the lead PDE4 inhibitor 1 to the quinolone 3 was identified as the major route of metabolism in the cynomolgus monkey. Modification of the template to give the cinnoline 9 retained potency and selectivity, and greatly improved the pharmacokinetic pro. le in the cynomolgus monkey compared with 1. Additional SAR studies aimed at improving the solubility of 9 are also described. (C) 2009 Elsevier Ltd. All rights reserved.
