What is the difference between PT-141 and Pinealon?
PT-141 is a cyclic heptapeptide melanocortin receptor agonist, a metabolite-like analogue of Melanotan II with a C-terminal acid, used in melanocortin receptor research (cyclic peptide, MW about 1025.2 g/mol).
Which is heavier, PT-141 or Pinealon?
PT-141 has a molecular weight of about 1025.2 g/mol and Pinealon about 418.4 g/mol (PubChem), so PT-141 is heavier by 606.8 g/mol, a ratio of 2.45. This means 1 mg of PT-141 contains 975.4 nmol versus 2,390.1 nmol for Pinealon.
How many mg of Pinealon are equimolar to 1 mg of PT-141?
1 mg of PT-141 (MW 1025.2) is 975.4 nmol. The same number of moles of Pinealon (MW 418.4) weighs 0.4081 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of PT-141 and Pinealon
PubChem lists PT-141 as C50H68N14O10 (1025.2 g/mol) and Pinealon as C15H26N6O8 (418.4 g/mol). PT-141 is a cyclic peptide; Pinealon is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of PT-141 equals how many mg of Pinealon in moles?
10 mg of PT-141 (MW 1025.2) is 9.754 µmol. The same amount of Pinealon (MW 418.4) would weigh 4.081 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of PT-141 equals how many mg of Pinealon in moles?
5 mg of PT-141 (MW 1025.2) is 4.877 µmol. The same amount of Pinealon (MW 418.4) would weigh 2.041 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Pinealon equals how many mg of PT-141 in moles?
10 mg of Pinealon (MW 418.4) is 23.901 µmol. The same amount of PT-141 (MW 1025.2) would weigh 24.503 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Pinealon equals how many mg of PT-141 in moles?
20 mg of Pinealon (MW 418.4) is 47.801 µmol. The same amount of PT-141 (MW 1025.2) would weigh 49.006 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
