Mafosfamide (INN) is an oxazaphosphorine (cyclophosphamide-like) alkylating agent under investigation as a chemotherapeutic. It is metabolized by cytochrome P450 into 4-hydroxycyclophosphamide, which is then converted into aldophosphamide, which, in turn yields the cytotoxic metabolites phosphoramide mustard and acrolein. [1]

Cyclophosphamide chemical compound

Cyclophosphamide (CP), also known as cytophosphane among other names, is a medication used as chemotherapy and to suppress the immune system. As chemotherapy it is used to treat lymphoma, multiple myeloma, leukemia, ovarian cancer, breast cancer, small cell lung cancer, neuroblastoma, and sarcoma. As an immune suppressor it is used in nephrotic syndrome, granulomatosis with polyangiitis, and following organ transplant, among other conditions. It is taken by mouth or injection into a vein.

An alkylating antineoplastic agent is an alkylating agent used in cancer treatment that attaches an alkyl group (CnH2n+1) to DNA.

Cytochrome P450

Cytochromes P450 (CYPs) are proteins of the superfamily containing heme as a cofactor and, therefore, are hemeproteins. CYPs use a variety of small and large molecules as substrates in enzymatic reactions. They are, in general, the terminal oxidase enzymes in electron transfer chains, broadly categorized as P450-containing systems. The term "P450" is derived from the spectrophotometric peak at the wavelength of the absorption maximum of the enzyme (450 nm) when it is in the reduced state and complexed with carbon monoxide.

Several Phase I trials have been completed. [2] [3]

Clinical trials are experiments or observations done in clinical research. Such prospective biomedical or behavioral research studies on human participants are designed to answer specific questions about biomedical or behavioral interventions, including new treatments and known interventions that warrant further study and comparison. Clinical trials generate data on safety and efficacy. They are conducted only after they have received health authority/ethics committee approval in the country where approval of the therapy is sought. These authorities are responsible for vetting the risk/benefit ratio of the trial – their approval does not mean that the therapy is 'safe' or effective, only that the trial may be conducted.

Idebenone is a drug that was initially developed by Takeda Pharmaceutical Company for the treatment of Alzheimer's disease and other cognitive defects. This has been met with limited success. The Swiss company Santhera Pharmaceuticals has started to investigate it for the treatment of neuromuscular diseases. In 2010, early clinical trials for the treatment of Friedreich's ataxia and Duchenne muscular dystrophy have been completed. As of December 2013 the drug is not approved for these indications in North America or Europe, and it was refused by the EMA for use in Leber's hereditary optic neuropathy (LHON) in 2013.

Neurofibroma Human disease

A neurofibroma is a benign nerve-sheath tumor in the peripheral nervous system. In 90% of cases, they are found as stand-alone tumors, while the remainder are found in persons with neurofibromatosis type I (NF1), an autosomal-dominant genetically inherited disease, they can result in a range of symptoms from physical disfiguration and pain to cognitive disability. Neurofibromas arise from nonmyelinating-type Schwann cells that exhibit biallelic inactivation of the NF1 gene that codes for the protein neurofibromin. This protein is responsible for regulating the RAS-mediated cell growth signaling pathway. In contrast to schwannomas, another type of tumor arising from Schwann cells, neurofibromas incorporate many additional types of cells and structural elements in addition to Schwann cells, making it difficult to identify and understand all the mechanisms through which they originate and develop.

4-Hydroxycyclophosphamide is in the class of oxazaphosphorine compounds, and is the main, active metabolite of cyclophosphamide and of mafosfamide after they partially metabolized by cytochrome P450. It is then partially tautomerized into aldophosphamide, which, in turn, easily enters live cells and then is partially detoxified into inactive carboxycyclophosphamide by the enzyme ALDH, but partially is hydrolyzed by another cell's enzyme phosphatase to the two directly cytotoxic metabolites - phosphoramide mustard and acrolein.
