GPS167 is a specific small-molecule splicing regulator and SRSF10 inhibitor that modulates BCLAF1 alternative splicing with an IC50 of 2 μM in human colorectal HCT116 cells, while also directly inhibiting CLK1, CLK2, and CLK4 but not SRPK1 or DYRK1A, positioning it as a mechanistically well-defined probe for studying spliceosome regulation and kinase-dependent RNA processing.

| In vivo | In preclinical rodent models, GPS167 effectively inhibits bone resorption and retinoid-induced hypercalcemia. Once localized on the bone surface via its high affinity for hydroxyapatite, the compound is internalized by osteoclasts during the resorption process. |
