Primary TargetActivity of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase

Product does not compete with ATP.

General description

An anti-hypercholesterolemic agent and an inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase that blocks a series of biological events including: activation of p21ras by insulin in 3T3-L1 fibroblasts and 3T3-L1 adipocytes, farnesylation of p21ras, which decreases the pool of intracellular Ras available for subsequent activation by growth factors (including insulin), and N-ras-induced neuronal differentiation. Causes cell cycle arrest in the late G1 phase. Shown to inhibit the stimulation of MAP kinase by insulin in HIRcB cells and block the transcription of the type-I SCR gene in THP-1-derived macrophages. Also blocks PDGF receptor tyrosine phosphorylation and MAP kinase activation by PDGF. This product requires activation for use in cell synchronization studies and in cell-free assay systems for HMG-CoA studies.

An anti-hypercholesterolemic agent that inhibits the activity of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase. Has been shown to block a series of biological events including: the activation of p21^ras by insulin in 3T3-L1 fibroblasts and 3T3-L1 adipocytes; the farnesylation of p21^ras, which decreases the pool of intracellular Ras available for subsequent activation by growth factors (including insulin); and N-ras-induced neuronal differentiation. Causes cell cycle arrest in the late G₁ phase through inhibition of proteasome. Has recently been shown to inhibit the stimulation of MAP kinase by insulin in HIRcB cells and to block the transcription of type-I SCR gene in THP-1-derived macrophages. Also blocks PDGF receptor tyrosine phosphorylation and MAP kinase activation by PDGF. This product requires activation for use in cell synchronization studies and in cell-free assay systems for HMG-CoA studies.
