Biological Activity

Description Taurolidine (Taurolin, Tauroline, Tauroflex) is a synthetic broad-spectrum antibiotic with antibacterial, anticoagulant and potential antiangiogenic activities.
In vitro

Taurolidine inhibits the growth of a rat metastatic colorectal tumor cell line in vitro[1]. Taurolidine possesses antineoplastic activity. The antiproliferative IC50 of taurolidine is in the 10-50 μM range, approximately 100-fold lower that that required for its antibiotic effects. Exposure to taurolidine induces apoptosis in SKOV-3 and PA-1 human tumor cells but apparently not in NIH-3T3 fibroblasts[2]. Taurolidine causes significant in vitro growth inhibition and cytotoxicity of human MM cells, which appears to be due, at least in part, to apoptosis[3].

In vivo In BD IX rats that underwent laparotomy, intraperitoneal instillation of DHD/K12/TRb tumor cells, local/intraperitoneal administration of taurolidine results in a marked decrease in tumor burden compared with control animals[1]. The i.p. administration of taurolidine effectively inhibits the development and growth of ovarian tumors when therapy is initiated on the day of tumor cell injection[2]. i.p. taurolidine inhibits adherence of colon tumor cells injected into the peritoneal cavity of rats[3].

Protocol (from reference)

Cell Research:[1]
  • Cell lines: a rat metastatic colorectal tumor cell line (DHD/K12/TRb)
  • Concentrations: 5, 10, 15, 25 mg/ml
  • Incubation Time: 14 h
  • Method: DHD/K12/TRb cells (1×105 cells/ml) are cultured in 24-well plates and incubated for 6 hours at 37°C in humidified 5% CO2 conditions to allow the cells to adhere. Culture medium is then removed and fresh culture medium alone (control) or culture medium with 5, 10, 15, and 25 mg/ml of Taurolidine is added. Cells are then incubated at 37°C in humidified 5% CO2 conditions for a further 14 hours followed by addition of 10 ml of BrdU labeling solution.
Animal Research:[1]
  • Animal Models: Adult male syngenic BD IX rats, aged 8-10 weeks
  • Dosages: 100 mg/kg
  • Administration: i.p.

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.
