What is the difference between FOXO4-DRI and Pal-GHK?
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 Pal-GHK?
FOXO4-DRI has a molecular weight of about 5358 g/mol and Pal-GHK about 578.8 g/mol (PubChem), so FOXO4-DRI is heavier by 4,779.2 g/mol, a ratio of 9.26. This means 1 mg of FOXO4-DRI contains 186.6 nmol versus 1,727.7 nmol for Pal-GHK.
How many mg of Pal-GHK 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 Pal-GHK (MW 578.8) weighs 0.108 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of FOXO4-DRI and Pal-GHK
PubChem lists FOXO4-DRI as C228H388N86O64 (5358 g/mol) and Pal-GHK as C30H54N6O5 (578.8 g/mol). FOXO4-DRI is a peptide (D-retro-inverso); Pal-GHK is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of FOXO4-DRI equals how many mg of Pal-GHK in moles?
5 mg of FOXO4-DRI (MW 5358) is 0.9332 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 0.5401 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 Pal-GHK in moles?
10 mg of FOXO4-DRI (MW 5358) is 1.866 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 1.08 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Pal-GHK equals how many mg of FOXO4-DRI in moles?
10 mg of Pal-GHK (MW 578.8) is 17.277 µmol. The same amount of FOXO4-DRI (MW 5358) would weigh 92.571 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
