What is the difference between FOXO4-DRI and N-Acetyl Epitalon?
FOXO4-DRI is a D-retro-inverso peptide designed to interfere with FOXO4-p53 binding, described in a 2017 Cell paper on senescent-cell research in mice (peptide (D-retro-inverso), MW about 5358 g/mol).
Which is heavier, FOXO4-DRI or N-Acetyl Epitalon?
FOXO4-DRI has a molecular weight of about 5358 g/mol and N-Acetyl Epitalon about 432.38 g/mol (PubChem), so FOXO4-DRI is heavier by 4,925.6 g/mol, a ratio of 12.39. This means 1 mg of FOXO4-DRI contains 186.6 nmol versus 2,312.8 nmol for N-Acetyl Epitalon.
How many mg of N-Acetyl Epitalon are equimolar to 1 mg of FOXO4-DRI?
1 mg of FOXO4-DRI (MW 5358) is 186.6 nmol. The same number of moles of N-Acetyl Epitalon (MW 432.38) weighs 0.0807 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of FOXO4-DRI and N-Acetyl Epitalon
PubChem lists FOXO4-DRI as C228H388N86O64 (5358 g/mol) and N-Acetyl Epitalon as C16H24N4O10 (432.38 g/mol). FOXO4-DRI is a peptide (D-retro-inverso); N-Acetyl Epitalon is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of FOXO4-DRI equals how many mg of N-Acetyl Epitalon in moles?
5 mg of FOXO4-DRI (MW 5358) is 0.9332 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 0.4035 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of FOXO4-DRI equals how many mg of N-Acetyl Epitalon in moles?
10 mg of FOXO4-DRI (MW 5358) is 1.866 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 0.807 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of N-Acetyl Epitalon equals how many mg of FOXO4-DRI in moles?
5 mg of N-Acetyl Epitalon (MW 432.38) is 11.564 µmol. The same amount of FOXO4-DRI (MW 5358) would weigh 61.959 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
