deptropine citrate

Deptropine citrate is a well-known H1-histamine receptor antagonist and muscarinic receptor antagonist. It is prescribed frequently for treatment of asthma. Recently deptropine has garnered interest as a potential treatment for breast cancer. In vitro studies have shown deptropine citrate has inhibitory effects on cell viability and mammosphere formation in Breast Cancer Stem Cells (BCSCs). However, it does not seem to inhibit the self-renewal capacity of the breast cancer cell line MDA-MB-231 when it is enriched with Cancer Stem Cells.
