Uses
Used in Pharmaceutical Industry:
Fulvestrant 17-Acetate is used as an intermediate in the synthesis of Fulvestrant 3-β-D-Glucuronide (F862510) for the development of pharmaceutical drugs. The compound is essential in creating a metabolite of Fulvestrant (F862500), which is a steroidal estrogen antagonist used in the treatment of hormone receptor-positive metastatic breast cancer.
Used in Cancer Treatment:
Fulvestrant 17-Acetate contributes to the development of cancer treatment options by being a part of the synthesis process for Fulvestrant 3-β-D-Glucuronide (F862510). This metabolite is derived from Fulvestrant (F862500), a drug that has demonstrated efficacy in treating hormone receptor-positive metastatic breast cancer by competitively binding to estrogen receptors, thereby blocking the effects of estrogen and inhibiting cancer cell growth.
Check Digit Verification of cas no
The CAS Registry Mumber 261506-24-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,5,0 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 261506-24:
(8*2)+(7*6)+(6*1)+(5*5)+(4*0)+(3*6)+(2*2)+(1*4)=115
115 % 10 = 5
So 261506-24-5 is a valid CAS Registry Number.

Putative metabolites of fulvestrant, an estrogen receptor downregulator. Improved glucuronidation using trichloroacetimidates
Ferguson,Harding,Killick,Lumbard,Scheinmann,Stachulski
, p. 3037 - 3041 (2007/10/03)
Following regioselective protection of the estrogen receptor downregulator fulvestrant (ICI 182,780) 1 as its 17-acetate 2 or 3-benzoate 4, the 3-sulfate 5 and 3- and 17-glucuronide conjugates 8 and 12 were prepared. Satisfactory preparation of 12 required use of the tri-O-isobutyryl imidate derivative 10 in conjunction with an inverse-addition technique not previously employed in glucuronidation. The value of this method for simpler aglycones is discussed together with a study of variations in donor acyl substituent and catalyst. Another putative metabolite, the 17-ketone 19, was prepared by direct oxidation of 1.
