Evaluation of Bupropion Hydrochloride Developmental Cardiotoxic Effects in Chick Cardiomyocyte Micromass Culture and stem cell derived Cardiomyocyte Systems

In this study, BPN developmental cardiotoxic effects in in vitro system were evaluated using chick cardiomyocyte micromass (MM) culture system and mouse embryonic stem cell derived cardiomyocyte (ESDC) system. In MM system, the cardiomyocyte contractile activity significantly decreased only at BPN 200 μM, while in ESDC system BPN concentration above 75 μM resulted in decreased contractile activity. The increase in drug concentration also affected the cardiomyocyte viability and total cellular protein content in both systems, but in ESDC system the cell viability failed to attain significant difference. The drug failed to induce reactive oxygen species production in both systems, but has affected the cardiac connexin43 expression especially in MM system. We observed that BPN showed developmental cardiotoxic effects irrespective of the stage of cardiac development in both in vitro systems
