Alaproclate is a selective serotonin reuptake inhibitor (SSRI).1,2 It inhibits depletion of serotonin (5-HT) induced by 4-methyl-α-ethyl-m-tyramine in rat cerebral cortex, hippocampus, hypothalamus, and striatum (EC50s = 18, 4, 8, and 12 mg kg, respectively).1 Alaproclate inhibits NMDA-evoked currents and depolarization-induced voltage-dependent potassium currents in rat hippocampal neurons (IC50s = 1.1 and 6.9 μM, respectively) and does not inhibit GABA-evoked currents when used at concentrations up to 100 μM.2 It increases sirtuin 1 (SIRT1) levels in N2a murine neuroblastoma cells expressing apolipoprotein E4 (ApoE4; IC50 = 2.3 μM) and in the hippocampus in the FXFAD-ApoE4 transgenic mouse model of Alzheimer's disease when administered at a dose of 20 mg kg twice daily.3 Alaproclate (40 mg kg) decreases immobility time in the forced swim test in rats, indicating antidepressant-like activity.4References1.

3-hydroxy Myristic acid methyl ester is a hydroxylated fatty acid methyl ester that has been found in E. camaldulensis and E. torelliana extracts. [1] It is active against M. tuberculosis (MIC = 49.5 μg ml) and is non-cytotoxic to Vero cells (IC50 = >100 μM). 3-hydroxy Myristic acid methyl ester is also a volatile compound that contributes to the aroma of red wild strawberries (F. pentaphylla) but is not present in cultivated strawberries (Fragaria x ananassa).[2] Reference:[1].
