Biological Activity
| Targets | MAO-A (Ki = 4.2 μM); MAO-B (Ki = 46 μM) |
| ln Vitro | In human brain synaptosomes and human liver mitochondria, bifemelane inhibits MAO-A in a dose-dependent manner with Kis values of 4.2±0.2 and 14.1±0.7 μM, respectively [1]. In human brain synaptosomes and human liver mitochondria, bifemelane inhibits MAO-B activity in a dose-dependent manner with Kis values of 46.0±3.6 and 65.2±7.0 μM, respectively [1]. |
| ln Vivo | Bifemelane (20-80 mg/kg; intraperitoneal injection) decreases exploratory activity in the open field test in a dose-dependent manner [3]. In the forced swim test, Bifemelane (20-80 mg/kg; intraperitoneal injection) shortens the immobility period [3], however the dose dependence is not evident and the maximum dosage of 20 mg/kg has been attained. |
| Enzyme Assay | 4-(O-Benzylphenoxy)-N-methylbutylamine (Bifemelane, BP-N-methylbutylamine), a new psychotropic drug, was found to inhibit monoamine oxidase (MAO) in human brain synaptosomes. It inhibited type A MAO (MAO-A) competitively and type B (MAO-B) noncompetitively. BP-N-methylbutylamine had a much higher affinity to MAO-A than an amine substrate, kynuramine, and it was a more potent inhibitor of MAO-A than of MAO-B. The Ki values of MAO-A and -B were determined to be 4.20 and 46.0 microM, respectively, while the Km values of MAO-A and -B with kynuramine were 44.1 and 90.0 microM, respectively. The inhibition of MAO-A and -B by BP-N-methylbutylamine was found to be reversible by dialysis of the incubation mixture. MAO-A in human placental and liver mitochondria and in a rat clonal pheochromocytoma cell line, PC12h, was inhibited competitively by BP-N-methylbutylamine, while MAO-B in human liver mitochondria was inhibited noncompetitively, as in human brain synaptosomes. BP-N-methylbutylamine was not oxidized by MAO-A and -B. The effects of other BP-N-methylalkylamines, such as BP-N-methylethylamine, -propylamine, and -pentanylamine, on MAO activity were examined. BP-N-methylbutylamine was the most potent inhibitor of MAO-A, and BP-N-methylethylamine and -propylamine inhibited MAO-B competitively, whereas BP-N-methylbutylamine and -pentanylamine inhibited it noncompetitively. Inhibition of these BP-N-methylalkylamines on MAO-A and -B is discussed in relation to their chemical structure[1]. |

Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals). Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] *Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.
