Identification
- Summary
Interferon alfa is an immunomodulator used to treat hepatitis B and C as well as certain types of cancer including cutaneous T-cell lymphoma and renal cell carcinoma.
- Generic Name
- Interferon alfa
- DrugBank Accession Number
- DB05258
- Background
Natural interferon alpha or Multiferon is obtained from the leukocyte fraction of human blood following induction with Sendai virus. Interferon alfa contains several naturally occurring IFN-α subtypes and is purified by affinity chromatography. Interferon alpha proteins are mainly involved in innate immune response against viral infection. They come in 13 subtypes that are called IFNA1, IFNA2, IFNA4, IFNA5, IFNA6, IFNA7, IFNA8, IFNA10, IFNA13, IFNA14, IFNA16, IFNA17, IFNA21. Multiferon consists of the 6 major subtypes are IFN-α1, IFN-α2, IFN-α8, IFN-α10, IFN-α14 and IFN-α21. Of these, IFN-α2 and IFN-α14 are glycosylated.

- Mechanism of action
Natural alpha interferon offers multiple subtypes of interferon which may work together as a 'cocktail-in-one', while recombinant versions only exhibit a single subtype." Viragen offers MultiferonT at a cost which is competitive with recombinant interferon regimens.
Natural alpha interferon contains the multiple subtype composition that is characteristic of interferon produced by the human body. It is believed that this results in a broader spectrum of specific anti-viral and immunoregulatory activity with the subtypes acting synergistically to give a wide-ranging response.
