Cat. No.	Product name	Field of application
DC73764	CRD733	CRD733 (ASP4901) is a potent, selective cGMP-specific PDE9 (phosphodiesterase 9) inhibitor.
DC70239	BAY 2666605	BAY2666605 is a potent, small molecule PDE3A-SLFN12 complex inducer with EC50 of 7 nM.BAY2666605 triggers the formation of a complex of two proteins called SLFN12 and PDE3A. This complex drive cancer cells into cell death by a mechanism called apoptosis.
DC48226	ONO-8430506	ONO-8430506 is an orally bioavailable and potent autotaxin (ATX)/ENPP2 inhibitor with the IC90 of 100 nM for ATX activity in mouse plasma.
DC47989	FPFT-2216	FPFT-2216, a “molecular glue” compound, degrades phosphodiesterase 6D (PDE6D), zinc finger transcription factors Ikaros (IKZF1), Aiolos (IKZF3), and casein kinase 1α (CK1α). FPFT-2216 can be used for the research of cancer and inflammatory disease.
DC42521	MBCQ	MBCQ is a potent and selective the type V phosphodiesterase (PDE V; PDE5) inhibitor with an IC50 of 19 nM. MBCQ has IC50s >100 µM for PDE1, PDE2, PDE3, and PDE4, respectively. MBCQ dilates coronary arteries via potent and specific inhibition of cGMP-PDE.
DC40977	DSR-141562	DSR-141562 is a novel, orally active, and selective brain-penetrant phosphodiesterase 1 (PDE1) inhibitor. DSR-141562 shows preferential selectivity for human PDE1B with an IC50 of 43.9 nM, and the IC50 values for human PDE1A and 1C are 97.6 and 431.8 nM, respectively. DSR-141562 can be used for the study of positive symptoms, negative symptoms and cognitive impairments associated with schizophrenia.
DC40378	MR-L2	MR-L2 is a reversible and noncompetitive allosteric activator of long-isoform phosphodiesterase-4 (PDE4), activates representative PDE4 long-isoform variants (PDE4A4, PDE4B1, PDE4C3, PDE4D5). MR-L2 suppresses PGE2-induced MDCK cell cyst formation with an EC50 of 1.2 μM.
