Product Description

Ifosfamide (formerly NSC-109724, Isophosphamide; Ifomide; Iphosphamid; iphosphamide; Isoendoxan; IsoEndoxan; Naxamide; Cyfos; Ifex; Ifosfamidum) is an approved anticancer medication which acts as a nitrogen mustard and DNA alkylating agent/alkylator. It has been used to treat a number of cancers, including ovarian cancer, non-Hodgkin'sand Hodgkin's lymphomas, pediatric solid tumors, and mall cell lung cancer. Ifosfamide is a prodrug that needs to be converted to its active form, isofosforamide mustard, which alkylates DNA, in the liver by cytochrome P450 enzymes.

DNA Alkylator
ln Vitro

In vitro activity: Ifosfamide (50 mM) raises the amounts of the proteins CYP3A4, CYP2C8, and CYP2C9 in hepatocytes, which in turn raises the rates of 4-hydroxylation in the hepatocytes that are cultured. Only one human hepatocyte culture, which also included the polymorphically expressed CYP3A5 in addition to the more broadly expressed CYP3A4, is induced by ifosfamide to produce CYP3A4.[1] Ifosfamide is a prodrug that is converted to isofosforamide mustard, the active alkylating compound, in the liver by cytochrome P450 mixed-function oxidase enzymes. In cases of non-Hodgkin'sand Hodgkin's lymphoma, ovarian cancer, pediatric solid tumors, and small cell lung cancer, ifosfamide has demonstrated favorable response rates.[2] Ifosfamide is extremely toxic to MCF-7 cells after stable CYP2B1 transfection, but neither the parental tumor cells nor an MCF-7 transfectant expressing beta-galactosidase are affected. Metyrapone, a CYP2B1 inhibitor, can significantly reduce this cytotoxicity.[3] The analysis of trabecular architecture indicates that the combination of Ifosfamide and Zoledronic acid is superior to either drug alone in terms of preventing tumor recurrence, enhancing tissue repair, and augmenting bone formation.[4]

ln Vivo
Ifosfamide (100 mg/kg, 200 mg/kg and 400 mg/kg) causes mice to exhibit a dose-dependent increase in bladder wet weight and Evans blue extravasation when injected intraperitoneally. When a mouse is given ifosfamide, they develop a severe case of cystitis that is marked by vascular congestion, edema, hemorrhage, fibrin deposition, neutrophil cell infiltration, and loss of epithelium. Ifosfamide exhibits both strong and diffuse necrosis on hematoxylin and eosin staining and strong cytoplasmic reactivity to inducible nitric oxide synthase. [5]
Cell Assay
A medium containing 2 milliliters is used to seed 4 × 104 cells in a 3-cm dish. When it comes to final concentrations, 0 to 5 mM of ifosfamide are added the following day. After the medium has been removed and the cells have been cleaned with PBS and either counted or stained, six more days are allowed[2].
Animal Protocol
Rats: Female rats are separated into four groups of eight before mating: group 1 is an untreated negative control group; group 2 is an injection of 1 mL of 0.9% NaCl; group 3 is an injection of 25 mg/kg Ifosfamide; and group 4 is an injection of 50 mg/kg Ifosfamide. Following five days of daily injections of Ifosfamide, three females are kept in a cage with one untreated male for a maximum of one week. Every day, vaginal smears are checked to see if someone is pregnant. In the event that sperm are found, the first 24 hours after mating are considered the first day of pregnancy. The expectant mothers are kept apart and regularly checked for symptoms of toxicity and miscarriage. On the eighteenth day of gestation, all pregnant animals are sacrificed by being beheaded. Serum is decanted and kept at -70°C until it is needed for the hormone assay. Cardiac blood (2.5–3 mL/rat) is collected in nonheparinized test tubes, centrifuged at 3,000× g for 30 min. The uterus and both ovaries are removed after blood collection, cleaned in saline solution, and the corpora lutea of pregnancy are counted visually. Each uterine horn is then examined to determine the number of viable fetuses, implantation sites, and resorption sites. Crown rump (CR) length is measured, weight is recorded, and each fetus is extracted from its umbilical cord. The placental weights are noted and the fetuses are inspected for external malformation. In order to facilitate histological and immunohistochemical analysis, fetuses and placentas from the control and treated groups are fixed in 10% neutral broth formalin.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
