Biological Activity

Description Oxfendazole (RS-8858) is a broad spectrum benzimidazole anthelmintic.
In vivo Oxfendazole (OX) induces not only mRNA expression of phase I enzymes Cyp1a1, Cyp1a2, but also Nrf2-regulated phase II enzymes such as Gpx2, Nqo1, Yc2, Akr7a3 and Gstm1 in rats, presumably due to an adaptive response against OX-induced oxidative stress. Oxfendazole enhances oxidative DNA damage (as assessed by 8-hydroxydeoxyguanosine; 8-OHdG) and lipid peroxidation (as assessed by thiobarbituric acid-reactive substances; TBARS) in rats. [1] Oxfendazole administered at the therapeutic dose (4.5 mg/kg) and at the highest dose (22.5 mg/kg) increase 1.54- and 2.36-fold the total liver microsomal cytochrome P450 and more particularly the isoenzyme P450IA2 (95% and 184% increases) in rabbit liver. [2] Oxfendazole MRL induces a mutagenic effect in all tested cell types. Oxfendazole exhibits embryotoxicity including teratogenicity. Oxfendazole induces a disturbance in the different biochemical contents of all tested tissues in mice. [3] Oxfendazole increases the incidence and multiplicity of altered foci (4.0- and 3.6-fold, respectively) and hepatocellular adenomas (HCAs) (3.0- and 5.5-fold, respectively). Oxfendazole treatment induces 5.2- and 5.6-fold increases in the number of proliferating cell nuclear antigen (PCNA)-positive cells and single-stranded DNA (ssDNA)-positive cells in HCAs compared with the surrounding tissue, respectively. [4] Oxfendazole and its sulphone metabolite attain a significantly higher plasma concentration and remain much longer in plasma compared with fenbendazole (FBZ) and albendazole (ABZ) and their respective metabolites in dogs.

Working concentration: mg/ml;

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.
