Design, synthesis and biological activity of β-carboline-based type-5 phosphodiesterase inhibitors
摘要:
The SAR of a series of beta-carboline derived type 5 phosphodiesterase inhibitors has been explored and we have discovered compounds with excellent levels of PDE5 potency and selectivity over PDE6. However, the series exhibits low levels of selectivity over PDE11, a phosphodiesterase with unknown function. (C) 2003 Elsevier Science Ltd. All rights reserved.
