By regulating intracellular cGMP levels, phosphodiesterase-9 (PDE9) plays a critical role in neuronal signaling, vascular function, and cell survival. By making our potent, selective, and brain-penetrant PDE9 inhibitor, BI 409306 (osoresonontrine) available to scientists free of charge, we incentivize new research to fully understand the role of the molecule in the context of disease.

A large portion of the proteome remains “undruggable” with traditional small molecules and biologics. To expand the druggable target landscape in areas of high unmet medical needs, novel innovative approaches could focus on targeting intracellular mechanisms, such as influencing nuclear translocation, organelle routing, molecular condensates, and spatial-temporal control mechanisms.

Vanin 1 and vanin 2 regulate cellular redox homeostasis and play key roles in maintaining oxidative balance and modulating inflammation. To advance further exploration, we offer BI-4122, a dual vanin 1/2 inhibitor. BI-4122 is optimized for intravenous and oral administration and comes along with BI-9534, an inactive control, to enable robust experimental designs.
