D-159404
D-159404 is an orally active, blood-brain barrier-permeable, selective allosteric PDE4D inhibitor. It partially inhibits cAMP hydrolysis by binding to the UCR2 regulatory domain, elevates intracellular cAMP levels, and triggers calcium influx, thereby improving working memory and episodic memory consolidation. D-159404 is used in research on asthma, chronic obstructive pulmonary disease, and cognitive impairment.
