Product Description
(6S,9S,12S)-Benzyl 12-benzyl-9-isobutyl-2,2-dimethyl-4,7,10-trioxo-6-phenethyl-3-oxa-5,8,11-triazatridecan-13-oate Is a phenylalanine analogue.
(6S,9S,12S)-Benzyl 12-benzyl-9-isobutyl-2,2-dimethyl-4,7,10-trioxo-6-phenethyl-3-oxa-5,8,11-triazatridecan-13-oate (CAS 868540-15-2) is a protected tripeptide derivative consisting of Boc-protected phenylalanine-leucine-phenylalanine benzyl ester. With a molecular formula of C₃₇H₄₇N₃O₆ and a molecular weight of 629.79 g/mol, it appears as a solid. This compound is a phenylalanine derivative and features a tert-butyloxycarbonyl (Boc) protecting group on the amino terminus and a benzyl ester protecting group on the carboxyl terminus. The systematic name reflects its structure as a tripeptide: Boc-protected α-aminophenylbutyryl-leucyl-phenylalanine benzyl ester. The compound contains three peptide bonds (4,7,10-trioxo) and has a high molecular complexity with 46 heavy atoms, 21 rotatable bonds, and a topological polar surface area of 122.83 Ų. The compound is a useful organic compound for life sciences research and is intended for research use only. It is typically stored at room temperature and is available with purity typically 95%.
Biological Activity I Assay Protocols (From Reference)
Targets
As a synthetic intermediate, (6S,9S,12S)-Benzyl 12-benzyl-9-isobutyl-2,2-dimethyl-4,7,10-trioxo-6-phenethyl-3-oxa-5,8,11-triazatridecan-13-oate has no specific biological target. Its role is to provide a protected tripeptide sequence (Phe-Leu-Phe) for incorporation into longer peptide chains. The Boc protecting group enables selective reactions during peptide chain assembly, while the benzyl ester protects the C-terminus. The compound's utility lies in peptide synthesis where pre-assembled peptide segments can be used to build longer sequences through fragment condensation strategies. The high lipophilicity (XLogP3 ~5.22) suggests the compound would have significant hydrophobic character if administered, but this is purely speculative as the compound is not intended for in vivo use.
ln Vitro
Commercial ergot supplements have been made from amino acids and their derivatives. They affect the release of anabolic hormones, the availability of fuel for activity, the ability to think clearly under pressure, and the prevention of muscular damage brought on by exertion. They are regarded as advantageous synergistic food ingredients [1].

Solubility in Formulation 1: ≥ 2.5 mg/mL (3.97 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 1.5878 mL 7.9392 mL 15.8783 mL
5 mM 0.3176 mL 1.5878 mL 3.1757 mL
10 mM 0.1588 mL 0.7939 mL 1.5878 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

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
