Mechanism of Action

Targets/IC₅₀/Ki	Reverse transcriptase ^[1]
In vitro	Stavudine (d4T) alters the lipid phenotype, decreasing the lipid content and expression of markers involved in lipid metabolism, namely C/EBPalpha, peroxisome proliferator-activated receptor gamma, adipocyte lipid binding protein 2, fatty acid synthase and acetyl-coenzyme A carboxylase. It drives 5-10% of 3T3-F442A cells towards apoptosis, and reduces the lipid content and survival of differentiated 3T3-L1 adipocytes. This compound increases mitochondrial mass by two to fourfold, and lowers the mitochondrial membrane potential (JC-1 stain). ^[1] It inhibits p24 antigen production by HIV-I in PBMC with EDsos ranging from 0.04 μM to 0.2 μM. ^[2] It also produces significant mitochondrial dysfunction with a 1.5-fold increase in cellular lactate to pyruvate ratios. Stavudine causes a dose-dependent decrease in mtDNA amplification and a correlative increase in abundance of markers of mitochondrial oxidative stress. Its treatment elevates mitochondrial reactive oxygen species (ROS), enhances mitochondrial oxidative stress, and contributes mechanistically to NRTI-induced toxicity. ^[3]
In vivo	Stavudine (d4T) (500 mg/kg/day) results in lack of significant oxidative mtDNA lesions (as assessed by long polymerase chain reaction experiments), and normal blood lactate/pyruvate ratios in lean mice. It can decrease hepatic and muscle mtDNA in lean mice and can also cause ketoacidosis during fasting without altering mtDNA. This compound depletes WAT mtDNA only in obese mice. ^[4]
