- Two human small cell lung cancer (SCLC) cell lines were used to evaluate the in vitro response to lonidamine and cisplatin exposure. The two cell lines both showed growth inhibition when exposed to lonidamine alone at concentrations greater than 50 micrograms/ml; however, one cell line (H69) was more sensitive. When cisplatin was combined with lonidamine a synergistic interaction was observed when cells were exposed to 10 microM cisplatin for 1 hour combined with lonidamine at concentrations of 50 micrograms/ml or greater. At a concentration of 25 micrograms/ml lonidamine combined exposure with cisplatin had no effect on cell growth or viability.
