PDEδ/NAMPT IN-1 (Compound 17d) is a dual inhibitor targeting phosphodiesterase 6 (PDE6) with a dissociation constant (KD) of 0.410 nM and nicotinamide phosphoribosyltransferase (NAMPT) with an inhibitory concentration (IC50) of 2.21 nM. It disrupts KRAS-related signaling by inhibiting NAMPT's role in the synthesis of nicotinamide adenine dinucleotide (NAD+), consequently inducing apoptosis in pancreatic cancer cells with KRAS mutations. This compound holds potential for research in KRAS-mutant pancreatic cancer.

KRAS4b-PDEδ stabilizer C19 is a stabilizer of the KRAS4b-PDEδ complex which decreases the proliferation of colorectal cancer cells, and increases apoptosis via decreased activation of oncogenic KRAS4b signaling.

K-Ras-PDEδ-IN-1 is a potent inhibitor of competitive K-Ras-PDEδ that binds to the farnesyl binding pocket of PDEδ (Kd of 8 nM).

IBMX (Methylisobutylxanthine) is a broad-spectrum phosphodiesterase (PDE) inhibitor with inhibitory activity against PDE3, PDE4, and PDE5 (IC50=6.5/26.3/31.7 μM). IBMX enhances the intracellular cAMP level.

Theophylline (1,3-Dimethylxanthine) is a methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac, and central nervous system stimulant activities. It inhibits the 3', 5'-cyclic nucleotide phosphodiesterase that degrades cyclic AMP, thus potentiating the actions of agents that act through adenylyl cyclases and cyclic AMP.

OR-1896 is the active metabolite of Levosimendan, a highly specific phosphodiesterase (PDE III) inhibitor, a vasodilator with partial anti-inflammatory properties that produces vasodilation in different types of blood vessels through activation of ATP-sensitive (KATP) and other potassium channels.OR-1896 can be used to study heart failure and vascular dysfunction. OR-1896 can be used to study heart failure and vascular dysfunction.

TPN171 is potent PDE5 inhibitor with subnanomolar potency for PDE5 and good selectivity over PDE6, which has the potential for the treatment of pulmonary arterial hypertension (PAH). TPN171 was proven to exert a longer lasting effect than sildenafil in animal models, providing a foundation for a once-daily oral administration for its clinical use.

WAY127093B racemate is the racemic mixture of WAY127093B, a phosphodiesterase IV inhibitor with demonstrated oral activity in rats and guinea pigs.

Oglemilast (GRC 3886) suppresses pulmonary cell infiltration, including eosinophilia and neutrophilia in vitro and in vivo. Oglemilast is an effective and orally active phosphodiesterase-4 (PDE4) inhibitor (IC50: 0.5 nM for PDE4D3). Oglemilast has the potential for inflammatory airway diseases.

PF-04447943 (Edelinontrine) is a potent and selective phosphodiesterase 9A inhibitor with an IC50 of 12 nM, which is 78-fold more selective than that used for other PDE family members (IC50>1000 nM).PF-04447943 exhibits anti-inflammatory activity, attenuates inflammatory responses by inhibiting oxidative stress, inflammation, and modulating T-cell polarization, and may be useful for research on sickle cell anemia.

Propentofylline (Hextol) is a methylxanthine derivative with neuroprotective, antiproliferative, and anti-inflammatory activity and enhanced synaptic adenosine signaling, which may be useful in the study of Alzheimer's disease, vascular dementia, cognitive impairment, dementia, and chronic pain.
