AB OBJECTIVE: Vesnarinone, OPC8212, is an inhibitor of TNF and IL-6
production in some cell culture systems. Our group has previously shown
that these factors act as mitogens for AIDS-KS in culture. We wanted to
determine if vesnarinone inhibits AIDS-KS cells in culture. METHODS:
Cultured AIDS-KS cells were plated at 2,000 cells/well in 24 well plates
and allowed to adhere overnight. Vesnarinone was dissolved in 100% DMSO
and added to fresh media and cells at concentrations from 10(-8) to
10(-5) M. Controls included serum free media with ITS+, 100% ethanol,
100% DMSO, dexamethasone in DMSO and retinal in DMSO at similar
concentrations. Cell counts were performed on days 3 and 6 using a
Coulter model ZM particle counter. The assays were repeated 4 times with
three different cell lines. RESULTS: Vesnarinone reproducibly inhibited
AIDS-KS cell proliferation at the 10(-6) to 10(-5) M range. Allow though
there was a clear solvent effect, the inhibition was seen regardless of
the conditions used (serum free, etc.) thus demonstrating a true drug
effect. Although there is superior inhibition at higher drug levels,
these are not achievable in patients. CONCLUSIONS: Vesnarinone inhibits
AIDS-KS cells in culture at pharmacologically achievable concentrations.
This agent might be useful in the clinical management of AIDS-KS.
