OSE-279 can be used for the research of advanced malignancies, colon cancer, hepatocarcinoma, mesothelioma.

Geranylgeranyl pyrophosphate is a type of isoprenoid metabolic intermediate, mainly synthesized through the mevalonate pathway. Geranylgeranyl pyrophosphate is a key precursor in various biological synthesis processes, especially as a necessary substrate for post-translational modification of proteins - geranylgeranyl phosphorylation. Geranylgeranyl pyrophosphate regulates various cellular processes and disease progression through protein geranylgeranyl phosphorylation, such as activating the YAP signaling pathway, promoting cell proliferation and inhibiting apoptosis; promoting IL-2 production and STAT5 phosphorylation; and influencing metabolic homeostasis and cancer, etc.
