Arecaidine propargyl ester is an agonist of M2 muscarinic acetylcholine receptors (mAChRs).1 It selectively binds to M2 over M1, M3, M4, and M5 mAChRs in CHO cells expressing the human receptors (Kis = 0.0871, 1.23, 0.851, 0.977, and 0.933 µM, respectively). Arecaidine propargyl ester induces contractions in isolated guinea pig atrium (pD2 = 8.67). It induces apoptosis and the production of reactive oxygen species (ROS) in U87 and U251 glioblastoma cells when used at a concentration of 100 µM.2 Arecaidine propargyl ester decreases mean arterial blood pressure in normotensive cats (ED25 = 1.9 nmol/kg).3 It is toxic to house flies (Musca) when administered at a dose of 75 µg/fly.4

The activation of M2 muscarinic receptor inhibits cell growth and survival in human epithelial ovarian carcinoma
J Cell Biochem 2022 Sep;123(9):1440-1453.PMID:35775813DOI:10.1002/jcb.30303
Ovarian cancer is the fifth leading cause of cancer-related deaths in females. Many ovarian tumor cell lines express muscarinic receptors (mAChRs), and their expression is correlated with reduced survival of patients. We have characterized the expression of mAChRs in two human ovarian carcinoma cell lines (SKOV-3, TOV-21G) and two immortalized ovarian surface epithelium cell lines (iOSE-120, iOSE-398). Among the five subtypes of mAChRs (M1-M5 receptors), we focused our attention on the M2 receptor, which is involved in the inhibition of tumor cell proliferation. Western blot analysis and real-time PCR analyses indicated that the levels of M2 are statistically downregulated in cancer cells. Therefore, we investigated the effect of Arecaidine propargyl ester hydrobromide (APE), a preferential M2 agonist, on cell growth and survival. APE treatment decreased cell number in a dose and time-dependent manner by decreasing cell proliferation and increasing cell death. FACS and immunocytochemistry analysis have also demonstrated the ability of APE to accumulate the cells in G2/M phase of the cell cycle and to increase the percentage of abnormal mitosis. The higher level of M2 receptors in the iOSE cells rendered these cells more sensitive to APE treatment than cancer cells. The data here reported suggest that M2 has a negative role in cell growth/survival of ovarian cell lines, and its downregulation may favor tumor progression.
