KW-2581
- CAS No.: 284045-56-3
- Formula:C25H36N2O4S
- Molecular Weight:460.63
IUPAC Name: (8S,9S,13S,14S)-17-(diisopropylcarbamoyl)-13-methyl-7,8,9,11,12,13,14,15-octahydro-6H-cyclopenta[a]phenanthren-3-yl sulfamate
InChIKey: OCJKMKKDAMUFAY-APDHKMKFSA-N
SMILES: O=S(OC1=CC=C2[C@@]3([H])CC[C@]4(C)C(C(N(C(C)C)C(C)C)=O)=CC[C@@]4([H])[C@]3([H])CCC2=C1)(N)=O
Biological Activity: KW-2581 is a steroidal selective steroid sulfatase (STS) inhibitor with an IC50 of 4 nM. KW-2581 inhibits STS activity of ZR-75-1 cells with an IC50 of 13 nM. KW-2581 inhibits the E1S-stimulated growth of ZR-75-1 cells with an IC50 of 0.18 nM. KW-2581 inhibits sulfated-estrogen dependent growth of breast cancer cells both in vitro and in vivo. KW-2581 induced regression in E1S-induced tumor growth. KW-2581 can be studied in research on hormone receptors-positive breast cancer[1][2].
