4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is a tobacco-specific nitrosamine carcinogen.1 Reactive metabolites of NNK alkylate DNA, forming pyridyloxobutyl (POB) and pyridylhydroxybutyl (PHB) adducts, and induce DNA methylation. NNK (100 mg/kg, single dose) increases the protein levels of DNA methyltransferase 1 (DNMT1) in mouse bronchial epithelial cells within one day and increases hypermethylation of the tumor suppressor genes Chd13, Prdm2, and Runx3 in lung tissue within three days.2 It induces tumor formation preferentially in the lung via various routes of administration in animal models.3 NNK induces adenomas and adenocarcinomas, which are present after 16 and 50 weeks, respectively, in mouse lung when administered at a single dose of 10 µmol/animal. Lifetime administration of NNK (63.5 mg/animal) to rats results in a 90% incidence of lung tumors.4

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

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.
