Background/aim: Osthole is a simple coumarin that has been found to have anticancer, anti-inflammatory, antiviral, anticoagulant, anticonvulsant and antiallergic activities. The aim of this study was to analyze the combined anti-proliferative effect of cisplatin (CDDP) and osthole on a rhabdomyosarcoma cell line, and assess the pharmacology of drug-drug interaction between these drugs using isobolographic analysis.
Materials and methods: The anticancer actions of osthole in combination with CDDP were evaluated using the tetrazolium dye-based MTT cell proliferation assay.
Results: Osthole and CDDP applied together augmented their anti-cancer activities and yielded an additive type of pharmacologic interaction by means of isobolographic analysis.
Conclusion: Combined therapy using osthole and cisplatin could be suggested as a potential chemotherapy regimen against rhabdomyosarcoma.
Keywords: CDDP; Osthole; isobolography; rhabdomyosarcoma.
