Natural Product Identification
Common NameCortisol 21-sulfate
DescriptionCortisol 21-sulfate, also known as SS441 compound or F(K)S CPD, belongs to the class of organic compounds known as sulfated steroids. These are sterol lipids containing a sulfate group attached to the steroid skeleton. A steroid sulfate obtained by the formal condensation of hydroxy group at position 21 of cortisol with sulfuric acid. Cortisol 21-sulfate was first documented in 1964 (PMID: 5857563). Cortisol 21-sulfate is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (PMID: 2152866) (PMID: 24392764) (PMID: 5012753) (PMID: 8650705).
