AB Baicalein and baicalin are components of Sho-saiko-to (SST), a Chinese
medical drug which is claimed to be therapeutically effective in
treating HIV-infected patients. Although 20 micrograms/ml of baicalin
was not cytotoxic to CEM cells, a cultured T cell line, it proved to be
cytotoxic to HIV-infected CEM cells (CEM-HIV) with a higher
HIV-releasing capacity and DNA fragmentation was detected within 24 hr
of incubation. However, after incubation of CEM-HIV with a lower dose of
baicalin (0.1, 0.3 and 2 micrograms/ml) for 24 and 48 hr, the viable
cell number increased by about 25% and the p24 release into the medium
was 25% lower than that of the control. After further incubation in the
presence of the agent for 6 and 9 days, only cells with a lower
HIV-releasing capacity survived. Baicalin might selectively induce
apoptosis of CEM-HIV cells which have a high virus-releasing capacity,
and stimulate proliferation of CEM-HIV which have a relatively lower
capacity of HIV-production.
