ABSTRACT
Interferons are first immunomodulatory molecules that have been shown to display a wide range of applications due to their antiviral, antibacterial, antitumor, and inflammatory activities. Natural and recombinant interferons are among most common biologic therapeutics worldwide. Interferon inducers, however, are less known and have been mostly developed and used in former socialist countries. Despite the fact that they are virtually unknown to the Western world, they represent a substantial market share of modern pharmacopoeia in former socialist republics. This review provides a brief description of most popular interferon inducers including Amyxin, Amizon, Anandin, Arbidol, Blasten, Cycloferon, Galavit, Groprinosine, Hepon, Immunoxel, Dzherelo, Kagocel, Larifan, Ligfol, Likopid, Mebavin, MIGI-KLP, V-5 Immunitor, SCV-07, Milife, Neovir, Poludan, Ragocin, Ridostin, Thymogen and Savratz, some of which were in use for several decades for the same clinical indications as for interferons. The variety and choice offered by the pharmaceutical industry behind the former "iron curtain" certainly deserves the appreciation, familiarity and application prospects for medical and research investigators worldwide.
