  • Patent number: 6248782
    Abstract: A therapeutic process for treating disease in mammals caused by retroviruses in which the infected mammal is treated with a ribonucleotide reductase inhibitor such as a polyhydroxy benzoic, mandelic or phenylacetic acid derivative, such as N,3,4-trihydroxybenzamide, a hlydroxyurea, a thiosemicarbazone or other ribonucleotide reductase inhibitor. The polyhydroxybenzoic acid derivatives are also useful in the treatment of diseases in mammals caused by DNA viruses.
