Arecaidine-propargyl ester
Arecaidine-propargyl ester is a selective M2 muscarinic receptor agonist with blood-brain barrier permeability, with a pKi of 5.91 for hm1, 7.06 for hm2, 6.07 for hm3, 6.01 for hm4, and 6.03 for hm5. Arecaidine-propargyl ester stimulates central and peripheral muscarinic receptors. Arecaidine-propargyl ester increases intracellular ROS, induces DNA damage and Apoptosis, and upregulates the expression of MnSOD and SIRT1. Arecaidine-propargyl ester reduces sympathetic nerve outflow, induces dose-dependent hypotension, and triggers negative chronotropic effects at high peripheral doses. Arecaidine-propargyl ester can be used in research related to Alzheimer's disease and glioblastoma.

Arecaidine-propargyl ester (0.01-1000 mM; 120 min) binds to cloned hm1, hm2, hm3, hm4, and hm5 muscarinic receptors expressed in CHO cells, with pKi values ranging from 5.91 to 7.06[2].
Arecaidine-propargyl ester (25-100 μM; 2 h) induces significant intracellular ROS production in glioblastoma cell lines U251MG and U87MG, and this effect is completely blocked by the ROS scavenger NAC[3].
Arecaidine-propargyl ester (100 μM; 72 h) induces significant apoptosis and reduces cell numbers in human glioblastoma cell lines U251MG and U87MG, with a stronger apoptotic effect on U251MG cells. Both of these effects are abrogated by the ROS scavenger NAC[3].
Arecaidine-propargyl ester (100 μM; 24-48 h) significantly upregulates the expression of SIRT1 protein in glioblastoma U251MG and U87MG cells in a time-dependent manner in vitro[3].
Arecaidine-propargyl ester (100 μM; 24-48 h) significantly upregulates the expression of MnSOD protein in U251MG and U87MG glioblastoma cells in a time-dependent manner[3].
Arecaidine-propargyl ester (100 μM; 24-48 h) significantly upregulates the mRNA expression level of Gadd45α in glioblastoma cell lines U251MG and U87MG[3].
Arecaidine-propargyl ester (100 μM; 24 h) increases total glutathione levels by 50% in U251MG glioblastoma cells, whereas no significant metabolic changes are detected in U87MG cells[3].
Arecaidine-propargyl ester (100 μM; 24-48 h) induces DNA double-strand breaks (detected by γ-H2AX positive rate) in glioblastoma cell lines U251MG and U87MG, and this effect depends on the activation of M2 muscarinic receptors in U251MG cells[3].
Arecaidine-propargyl ester (50-100 μM; 24 h) induces significant chromosomal aberrations in glioblastoma U251MG and U87MG cells; among them, U251MG cells exhibit higher sensitivity at 50 μM, and only U251MG cells show a significant increase in sister chromatid exchange levels at 50 μM[3].

Animal Model:either sex, weight 2-4 kg (anaesthetized for cardiovascular function monitoring)[1]
-
Dosage:1.0 × 10-9 moles/kg (vertebral artery); 1.4 × 10-9 moles/kg (femoral vein)
-
Administration:left vertebral artery; femoral vein
-
Result:Caused dose-dependent reduction in mean arterial pressure (intravenous), which was blocked by intravenous methylatropine (300 μg/kg) but not centrally administered atropine (30 μg/kg) or D-benzethimide (10 μg/kg).
Caused dose-dependent reduction in mean arterial pressure (vertebral artery), which was not blocked by intravenous methylatropine (300 μg/kg) but was blocked by vertebral artery-administered atropine (50 μg/kg) or D-benzethimide (10 μg/kg).
Did not alter heart rate with central administration; only relatively high intravenous doses caused a decrease in cardiac frequency.
Exhibited ED-25 of 1.0 × 10-9 moles/kg via vertebral artery and 1.4 × 10-9 moles/kg via femoral vein.
