With the animal cell cyclic AMP density rise medicine or the ultrafiltration membrane above cyclic nucleotide phosphodiesterase inhibiter null

摘要

PROBLEM TO BE SOLVED: To obtain a cyclic AMP level increasing agent or a cyclic nucleotide phosphodiesterase inhibitor having an activity in acting on a mammalian cell and raising the cyclic AMP level, capable of substituting for hormones using the cyclic AMP as a second messenger and providing a medicine useful for improving health such as suppression of an increase in endothelial-permeability due to pulmonary vascular endothelial inflammation or a specific food material for health.;SOLUTION: This mammalian cell cyclic AMP level increasing agent or cyclic nucleotide phosphodiesterase inhibitor for the mammalian cell comprises a polymer of p-coumaric acid.;COPYRIGHT: (C)2002,JPO
