Geranylgeranyl pyrophosphate triammonium 

Geranylgeranyl pyrophosphate triammonium is a type of isoprenoid metabolic intermediate, mainly synthesized through the mevalonate pathway. Geranylgeranyl pyrophosphate triammonium is a key precursor in various biological synthesis processes, especially as a necessary substrate for post-translational modification of proteins - geranylgeranyl phosphorylation. Geranylgeranyl pyrophosphate triammonium 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^{[1][2][3][4][5][6]}.

Geranylgeranyl pyrophosphate (10 μM, 24 h) triammonium completely reverses the inhibition of insulin-stimulated glucose uptake and the disorder of GLUT4 membrane translocation caused by Simvastatin (HY-17502) in C2C12 cells^[1].
Geranylgeranyl pyrophosphate (25 μM, 72 h) triammonium regulates the TGF-β1-induced fibroblast-myofibroblast transformation through linalyl modification^[2].
Geranylgeranyl pyrophosphate (10 μM, 48 h) triammonium promotes hepatic lipid accumulation by prenylation of Perilipin4 in primary mouse liver cells^[3].
Geranylgeranyl pyrophosphate (10 μM, 96 h) triammonium in primary CD4⁺ and CD25 T cells modifies Ras protein by geranylgeranylylation, activates the Ras/ERK pathway, promotes IL-2 expression, and thereby enhances STAT5 phosphorylation, driving T_reg cell differentiation^[4].
Geranylgeranyl pyrophosphate (10 μM, 12 h) triammonium completely reverses the proliferation defect and cell apoptosis caused by GGPS1 knockdown or Simvastatin in human umbilical vein endothelial cells^[5].
Geranylgeranyl pyrophosphate triammonium, when its levels are reduced, inhibits the geranylgeranylation of oncogenic GTPases, ultimately inducing cancer cell death^[6].

Geranylgeranyl pyrophosphate (10 mg/kg, i.p., once daily for 10 days) triammonium inhibits the inflammatory response mediated by Th1/Th17, thereby alleviating the mice colitis induced by DSS (HY-116282C)^[4].
