项目摘要
Project Summary/Abstract
Proliferative diabetic retinopathy, wet age-related macular degeneration, and retinopathy of prematurity are all
diseases of the eye that can lead to blindness and are due to abnormal development of retinal or choroid blood
vessels. Although intravitreal anti-angiogenic therapies targeting vascular endothelial growth factor signaling
are generally effective for these diseases, spontaneous or acquired resistance is a significant problem and
points to the need for high-quality cell-based chemical probes for interrogating angiogenic pathways and
developing alternative therapies. To address this unmet need, we propose developing high-quality cell-based
chemical probes for the profilin1 (Pfn1)-actin protein-protein interaction. Pfn1 is critical for angiogenesis as it
plays a vital role in the dynamic remodeling of the actin cytoskeleton in response to angiogenic signals. We
have shown in numerous contexts that inhibition or suppression of Pfn1 leads to reduced angiogenesis and
have recently demonstrated that inhibiting Pfn1 reduces the formation of new blood vessels in both ex vivo
and in vivo models of retinopathy. We have already identified a validated hit compound that inhibits the
Pfn1-actin interaction in biochemical and cell-based assays and confirmed its target engagement in cells. To
increase the potency of this inhibitor while maintaining drug-like properties, we will employ an iterative
optimization process that will be guided by our structural and cheminformatic models and by the structure-
activity relationship that will be developed around the key points of variation during each iteration of compound
selection, synthesis, and biological testing. Derivatives will be evaluated in a gated assay cascade to determine
their binding affinity for Pfn1 and activity in cells. This iterative process aims to identify an inhibitor of the Pfn1-
actin interaction with sub-micromolar potency in both biochemical and cellular assays. Compounds that meet
well-defined criteria for novelty and potency in our first round of assays will be validated in the second series
of assays to confirm target engagement, selectivity, and other functional utilities (e.g., synergy with an anti-
VEGF agent and barrier-function modulatory agent). Successful completion of these studies will result in a
potent and specific inhibitor of Pfn1-actin for studying the role of Pfn1 in aberrant angiogenesis and may
ultimately lead to a clinical candidate for the treatment of eye disease.
