The present application is a continuation-in-part of U.S. application Ser. No. 07/279,417, filed on Dec. 2, 1988, now pending which, in turn, is a continuation-in-part of U.S. application Ser. No. 07/147,713, now U.S. Pat. No. 4,866,054 and U.S. application Ser. No. 07/147,714 now U.S. Pat. No. 4,866,053 both filed on Jan. 25, 1988, which, in turn, are continuation-in-parts of U.S. application Ser. No. 06/862,804, filed on May 13, 1986, now abandoned. The contents of U.S. application Ser. Nos. 07/279,417, 07/147,713, 07/147,714, and 06/862,804 are hereby incorporated by reference into the present disclosure. The present invention relates to metallo-organic cobalt compounds and their use in the treatment of subjects for conditions and diseases caused by viruses and viral infections. It has been discovered that certain conditions and diseases, e.g., inflammation, burns, wounds, and diseases caused by bacteria and fungi in mammalian species can be treated with certain complexes of cobalt having the structure: ##STR3## wherein R.sub.1 and R.sub.1' are the same or different and each is an alkyl group, a phenyl group or a substituted derivative of a phenyl group; wherein R.sub.2 and R.sub.2' are the same or different and each is hydrogen, an unbranched alkyl group, a halide or a group having the structure ##STR4## wherein R is hydrogen, an alkoxide group, an alkyl group, or OH; wherein R.sub.3 and R.sub.3' are the same or different and each is hydrogen or an alkyl group; wherein X and X' are the same or different and each is a water soluble group having weak to intermediate ligand field strength; and Q.sup.- is a soluble, pharmaceutically acceptable negative ion. To date, however, such uses have been the only ones disclosed for these complexes. Today, virus infections are known to be significant causes of morbidity and mortality in human and veterinary medicine. Many of these diseases are untreatable or the available therapies are not entirely satisfactory and only provide minimal clinical response. For the most part, it is known that viral diseases do not respond to therapy with conventional antibiotics. Despite some recent successes in the development of antiviral chemotherapeutic agents, new treatments for these diseases are needed to improve the management of viral infections in clinical medicine. I have discovered that compounds having the structure of Formula I exhibit significant activity as antiviral agents. In addition, I have discovered that the compounds exhibit significant activity in comparison with known licensed antiviral agents. The compounds can be used for treating viral infections as is, or in a composition form when combined with a pharmaceutically acceptable carrier. Depending on the nature of the infection and the manner in which it manifests itself, the inventive antiviral compositions may be administered by using conventional modes of administration, e.g., oral, topical application, parenteral, and the like. The antiviral composition of the invention comprises a suitable pharmaceutically acceptable carrier and the inventive compound in an amount effective to suppress the replication and/or abort the infective life cycle of the virus causing the infection.
