What is the difference between PT-141 and Triptorelin?
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 Triptorelin?
PT-141 has a molecular weight of about 1025.2 g/mol and Triptorelin about 1311.4 g/mol (PubChem), so Triptorelin is heavier by 286.2 g/mol, a ratio of 1.28. This means 1 mg of PT-141 contains 975.4 nmol versus 762.5 nmol for Triptorelin.
How many mg of Triptorelin 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 Triptorelin (MW 1311.4) weighs 1.279 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of PT-141 and Triptorelin
PubChem lists PT-141 as C50H68N14O10 (1025.2 g/mol) and Triptorelin as C64H82N18O13 (1311.4 g/mol). PT-141 is a cyclic peptide; Triptorelin 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 Triptorelin in moles?
10 mg of PT-141 (MW 1025.2) is 9.754 µmol. The same amount of Triptorelin (MW 1311.4) would weigh 12.792 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 Triptorelin in moles?
5 mg of PT-141 (MW 1025.2) is 4.877 µmol. The same amount of Triptorelin (MW 1311.4) would weigh 6.396 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 2 mg vial of Triptorelin equals how many mg of PT-141 in moles?
2 mg of Triptorelin (MW 1311.4) is 1.525 µmol. The same amount of PT-141 (MW 1025.2) would weigh 1.564 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Triptorelin equals how many mg of PT-141 in moles?
5 mg of Triptorelin (MW 1311.4) is 3.813 µmol. The same amount of PT-141 (MW 1025.2) would weigh 3.909 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
