Biological Activity

Description Stavudine (d4T, BMY-27857, Sanilvudine, NSC 163661) is a nucleoside analog reverse transcriptase inhibitor (NARTI) active against HIV.
Reverse transcriptase [1]
In vitro

Stavudine alteres 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. Stavudine drives 5-10% of 3T3-F442A cells towards apoptosis, and reduces the lipid content and survival of differentiated 3T3-L1 adipocytes. Stavudine increases mitochondrial mass by two to fourfold, and loweres the mitochondrial membrane potential (JC-1 stain). [1] stavudine inhibits p24 antigen production by HIV-I in PBMC with EDsos ranging from 0.04 μM to 0.2 μM. [2] Stavudine 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. Stavudine treatment elevates mitochondrial reactive oxygen species (ROS), enhances mitochondrial oxidative stress, and contributes mechanistically to NRTI-induced toxicity. [3]

In vivo Stavudine (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. Stavudine (500 mg/kg/day) can decrease hepatic and muscle mtDNA in lean mice and can also cause ketoacidosis during fasting without altering mtDNA. Stavudine (500 mg/kg/day) depletes WAT mtDNA only in obese mice. [4]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
