Interferon alfa-n3
drug data and news
Interferon alfa-n3 drug data, resources, and news articles (when available). Onconews.org provides news on cancer research. This section, which includes profiles on medicines that may or not be cancer-related is in beta form. If things run smoothly we will be releasing a new format late in the summer of 2006.

| Generic name | Interferon alfa-n3 | ||
| Brand Names/Synonyms | Interferon alpha-2 precursor;Interferon alpha-A;LeIF A; Alferon (Interferon Sciences Inc.) | ||
| Indication | For treatment of hairy cell leukemia, malignant melanoma, and AIDS-related Kaposi's sarcoma | ||
| Sponsored links | Description | Purified, natural (n is for natural) human interferon alpha proteins (consists of 3 forms or polymorphisms including 2a, 2b and 2c). 166 residues, some are glycosylated (MW range from 16 kD to 27 kD) | |
| Pharmacology | Upregulates the expression of MHC I proteins, allowing for increased presentation of peptides derived from viral antigens. This enhances the activation of CD8+ T cells that are the precursors for cytotoxic T lymphocytes (CTLs) and makes the macrophage a better target for CTL-mediated killing. Interferon alpha also induce the synthesis of several key antiviral mediators, including 2'-5' oligoadenylate synthetase (2'-5' A synthetase), beta-2 microglobulin, neopterin and protein kinase R. | ||
| Mechanism Of Action | Interferon alpha binds to type I interferon receptors (IFNAR1 and IFNAR2c) which, upon dimerization, activate two Jak (Janus kinase) tyrosine kinases (Jak1 and Tyk2). These transphosphorylate themselves and phosphorylate the receptors. The phosphorylated INFAR receptors then bind to Stat1 and Stat2 (signal transducers and activators of transcription) which dimerize and activate multiple (~100) immunomodulatory and antiviral proteins. Interferon alpha binds less stably to type I interferon receptors than interferon beta. | ||
