Members of the anthracycline family of drugs such as daunorubicin (DNR
) are currently being employed in cancer therapy, treatment of Kaposi'
s sarcoma and lymphomas in HIV-1 infected patients. These drugs may ha
ve an antiviral activity against HIV-1. Experiments conducted on U937
(a promonocytic cell line), peripheral blood monocytes (without T cell
s) and infected with HIV-1 showed anti-viral activity at nanogram/ml c
oncentrations, without affecting cell proliferation and cell viability
. Treatment of Hut 78 cells (a T cell line) with DNR was not as effect
ive in inhibiting HIV-1 replication when compared to the anti-HIV acti
vity in cells of the monocyte lineage.
