What is the difference between SLU-PP-332 and P21?
SLU-PP-332 is a small-molecule agonist of the estrogen-related receptors (ERR alpha, beta and gamma) studied in mitochondrial and exercise-mimetic research in mice (small molecule (not a peptide), MW about 290.3 g/mol).
Which is heavier, SLU-PP-332 or P21?
SLU-PP-332 has a molecular weight of about 290.3 g/mol and P21 about 578.7 g/mol (PubChem), so P21 is heavier by 288.4 g/mol, a ratio of 1.99. This means 1 mg of SLU-PP-332 contains 3,444.7 nmol versus 1,728 nmol for P21.
How many mg of P21 are equimolar to 1 mg of SLU-PP-332?
1 mg of SLU-PP-332 (MW 290.3) is 3,444.7 nmol. The same number of moles of P21 (MW 578.7) weighs 1.993 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of SLU-PP-332 and P21
PubChem lists SLU-PP-332 as C18H14N2O2 (290.3 g/mol) and P21 as C27H42N6O8 (578.7 g/mol). SLU-PP-332 is a small molecule (not a peptide); P21 is a peptidomimetic. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of P21 equals how many mg of SLU-PP-332 in moles?
10 mg of P21 (MW 578.7) is 17.28 µmol. The same amount of SLU-PP-332 (MW 290.3) would weigh 5.016 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of P21 equals how many mg of SLU-PP-332 in moles?
5 mg of P21 (MW 578.7) is 8.64 µmol. The same amount of SLU-PP-332 (MW 290.3) would weigh 2.508 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of SLU-PP-332 equals how many mg of P21 in moles?
10 mg of SLU-PP-332 (MW 290.3) is 34.447 µmol. The same amount of P21 (MW 578.7) would weigh 19.935 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of SLU-PP-332 equals how many mg of P21 in moles?
5 mg of SLU-PP-332 (MW 290.3) is 17.224 µmol. The same amount of P21 (MW 578.7) would weigh 9.967 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
