Description
1,3,5[10]-ESTRATRIENE-3,17BETA-DIOL 3-SULFATE SODIUM SALT, also known as 17β-Estradiol 3-O-Sulfate Sodium Salt, is a neuroactive steroid derived from β-Estradiol. It is a sulfated form of the naturally occurring hormone 17β-Estradiol, which is secreted by developing ovaries and is predominant during premenopause in women. 1,3,5[10]-ESTRATRIENE-3,17BETA-DIOL 3-SULFATE SODIUM SALT has been widely studied for its various applications in the field of neuroscience and analytical chemistry.
Uses
Used in Pharmaceutical Industry:
1,3,5[10]-ESTRATRIENE-3,17BETA-DIOL 3-SULFATE SODIUM SALT is used as a research compound for studying human recombinant p1 γ-aminobutyric acid type C (GABAC) receptors. The application reason is that it serves as a neuroactive steroid, which can help in understanding the role of GABAC receptors in the central nervous system and their potential involvement in various neurological disorders.
Used in Analytical Chemistry:
1,3,5[10]-ESTRATRIENE-3,17BETA-DIOL 3-SULFATE SODIUM SALT is used as an analytical standard for measuring the estradiol level from culture supernatant in ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The application reason is that it provides a reliable and accurate method for quantifying estradiol levels, which can be crucial in various research and diagnostic applications.
Biochem/physiol Actions
β-Estradiol is a steroid hormone involved in a number of organ functions. It is significantly associated with brain functions including neuroprotection, neurogenesis and synaptic plasticity. β-Estradiol maintains bone homeostasis, hence it is preferred for osteoporosis therapy. 17-β-Estradiol is the most active estrogen generated in our body. During postmenopausal, 17-β-estradiol inhibits oxidative modification in low density lipoprotein. This indicates that estrogen replacement therapy might be useful in treating cardiovascular disease.
Check Digit Verification of cas no
The CAS Registry Mumber 4999-79-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4999-79:
(6*4)+(5*9)+(4*9)+(3*9)+(2*7)+(1*9)=155
155 % 10 = 5
So 4999-79-5 is a valid CAS Registry Number.

Sulfation of various alcoholic groups by an arylsulfate sulfotransferase from desulfitobacterium hafniense and synthesis of estradiol sulfate

Bacterial arylsulfate sulfotransferases (AST) are enzymes that catalyse the transfer of a sulfate group from p-nitrophenyl sulfate (p-NPS) to a phenolic acceptor molecule. By screening of the NCBI protein database a gene coding for an AST was found in Desulfitobacterium hafniense. After expression the enzyme was purified and characterised. This AST efficiently sulfates various acceptor molecules (estrone, estradiol, enkephalin and non-phenolic alcohols) using p-NPS as sulfate donor. The purified AST has a pH optimum of 9.6, it is stable in the presence of 10% of DMSO, and depending on the conditions it has a melting temperature of up to 47°C. Surprisingly, and in great contrast to all other known bacterial ASTs, this enzyme was able to use a variety of non-phenolic alcohols as sulfate acceptor. Because of these properties, this unique enzyme is a promising tool for biotransformation processes, providing a green and simple method to specifically sulfate compounds without need for functional group protection.
