Product Description
RN-1 diHCl is a potent, BBB (blood-brain barrier) permeable/penetrable, irreversible, selective lysine-specific demethylase 1 (LSD1) inhibitor (antagonist) with IC50 of 70 nM. RN-1 diHCl has higher selectivity for LSD1 than MAO-A and MAO-B, with IC50s of 0.51 μM and 2.785 μM respectively.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
With an IC50 value of roughly 100–200 μM, RN-1 dihydrochloride is cytotoxic to ovarian cancer cells (SKOV3, OVCAR3, A2780, and cisplatin inhibitor A2780cis) [3].
ln Vivo
RN-1 dihydrochloride (3–10 mg/kg; i.p.; daily; for 2 or 4 weeks) effectively induces fetal hemoglobin (HbF) levels in red blood cells and decreases disease pathology in SCD [2]. In /6 rats, concentrations in the brain/arterial exposure ratio was 88.9 after 24 hours of intraperitoneal administration of RN-1 dihydrochloride (10 mg/kg).
Animal Protocol
Animal/Disease Models: Sickle cell disease (SCD) mice [2]
Doses: 3mg/kg or 10mg/kg
Route of Administration: ip; 1 dihydrochloride Dramatically impairs long-term memory, but not short-term memory [1 ]. Routine; 2 or 4 consecutive weeks
Experimental Results: Effectively induced HbF levels in red blood cells and diminished disease pathology in SCD mice.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
g/mol

Molecular Weight Calculator allows you to calculate the molar mass and elemental composition of a compound, as detailed below:

Note: Chemical formula is case sensitive: C12H18N3O4  c12h18n3o4
Instructions to calculate molar mass (molecular weight) of a chemical compound:
  • To calculate molar mass of a chemical compound, please enter the chemical/molecular formula and click the “Calculate’ button.
Definitions of molecular mass, molecular weight, molar mass and molar weight:
  • Molecular mass (or molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
  • Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Reconstitution Calculator allows you to calculate the volume of solvent required to reconstitute your vial.

  • Enter the mass of the reagent and the desired reconstitution concentration as well as the correct units
  • Click the “Calculate” button
  • The answer appears in the Volume (to add to vial) box

Working concentration mg/mL;

Method for preparing DMSO stock solution mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.

Method for preparing in vivo formulation:Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.

(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
             (2) Be sure to add the solvent(s) in order.

Biological Data
  • Covalent inhibition assays. (A) LSD1 enzyme was incubated with the inhibitor RN-1 and then diluted to determine if inhibitor dissociation occurs. DMSO was used as the control in this reaction. RN-1 inhibited the enzyme at high dilutions indicating that inhibition was not reversible. (B) Representative progress curves for LSD1 activity in the presence of varying concentrations of RN-1. LSD1 enzyme was incubated with the inhibitor RN-1 and then serially diluted at 1 min time intervals to determine if the inhibitor would dissociate. DMSO was used as the control in this reaction. RN-1 can be diluted and enzyme activity partially restored up to 4 min after initial incubation. After this time, LSD1 remains fully inhibited even after a 1:100 dilution.[1].Ramesh Neelamegam, et al. Brain-penetrant LSD1 inhibitors can block memory consolidation.
