What is the difference between Semax and SNAP-8?

Semax is a heptapeptide analogue of the ACTH(4-7) fragment extended with Pro-Gly-Pro, studied in neuropeptide and BDNF-expression research in rodent models (peptide, MW about 813.9 g/mol).

Which is heavier, Semax or SNAP-8?

Semax has a molecular weight of about 813.9 g/mol and SNAP-8 about 1075.2 g/mol (PubChem), so SNAP-8 is heavier by 261.3 g/mol, a ratio of 1.32. This means 1 mg of Semax contains 1,228.7 nmol versus 930.1 nmol for SNAP-8.

How many mg of SNAP-8 are equimolar to 1 mg of Semax?

1 mg of Semax (MW 813.9) is 1,228.7 nmol. The same number of moles of SNAP-8 (MW 1075.2) weighs 1.321 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of Semax and SNAP-8

PubChem lists Semax as C37H51N9O10S (813.9 g/mol) and SNAP-8 as C41H70N16O16S (1075.2 g/mol). Semax is a peptide; SNAP-8 is a peptide. These formulas refer to the parent compounds without salt counter-ions.

A 5 mg vial of SNAP-8 equals how many mg of Semax in moles?

5 mg of SNAP-8 (MW 1075.2) is 4.65 µmol. The same amount of Semax (MW 813.9) would weigh 3.785 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 10 mg vial of SNAP-8 equals how many mg of Semax in moles?

10 mg of SNAP-8 (MW 1075.2) is 9.301 µmol. The same amount of Semax (MW 813.9) would weigh 7.57 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 5 mg vial of Semax equals how many mg of SNAP-8 in moles?

5 mg of Semax (MW 813.9) is 6.143 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 6.605 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 10 mg vial of Semax equals how many mg of SNAP-8 in moles?

10 mg of Semax (MW 813.9) is 12.287 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 13.21 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 30 mg vial of Semax equals how many mg of SNAP-8 in moles?

30 mg of Semax (MW 813.9) is 36.86 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 39.631 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
