 AB    Six anti-AIDS drugs were assessed for in vivo genotoxicity and
       cytotoxicity at human clinical doses with the mouse bone marrow
       micronucleus assay. These included four dideoxynucleosides
       (azidothymidine, dideoxycytidine, dideoxyadenosine, and dideoxyinosine),
       an anthracycline antibiotic (doxorubicin), and a chelating agent
       (D-penicillamine). Cytological analysis of the mouse bone marrow cells
       revealed: (i) The dideoxynucleosides and D-penicillamine failed to
       induce significant number of micronuclei, and except for one of the five
       doses of dideoxyinosine, none of the dideoxynucleosides were cytotoxic
       at the doses tested. (ii) Doxorubicin induced micronuclei in a
       dose-dependent manner which was statistically significant at 4-times the
       clinical dose but was not cytotoxic at any of the doses tested.
