Cyclic AMP phosphodiesterase 4 isoenzyme inhibitory activity of (R)- and (S)-isomer of 7-methyl- or 8-alkyl-4,5,7,8-tetrahydroimidazo[2,1-i]- purin-5-one.
We investigated the structure-activity relationship of the (R)- and (S)-isomer of 7-methyl- and 8-alkyl-tetrahydroimidazo[2,1-i]purines for phosphodiesterase 4 (PDE4) inhibitors. (S)-8-Isopropyl-3,4-dipropyl-imizazo[2,1-i]purine (S)-2c exhibited both potent and selective PDE4 inhibitory activity.
