Click chemistry inspired highly facile synthesis of triazolyl ethisterone glycoconjugates.[Pubmed:24316164]
Steroids. 2014 Feb;80:71-9.
Numerous deoxy-azido sugars 3 were prepared by the reaction of tosyl/bromo sugars with NaN3 in dry DMF under heating condition. The 1,3-dipolar cycloaddition of deoxy-azido sugars 3 with Ethisterone 4 to afford regioselective triazole-linked Ethisterone glycoconjugates 5 was investigated in the presence of CuI and DIPEA in dichloromethane or CuSO4.5H2O and sodium ascorbate in aqueous medium. All the developed compounds were characterized by spectroscopic analysis (IR, (1)H &(13)C NMR, and MS spectra). Structure of triazolyl Ethisterone glycoconjugate 5a has been further confirmed by its Single Crystal X-ray analysis.
Synthesis and preliminary evaluation of a (18) F-labeled ethisterone derivative [(18) F]EAEF for progesterone receptor targeting.[Pubmed:27696769]
Chem Biol Drug Des. 2017 Apr;89(4):559-565.
To develop a novel progesterone receptor-targeting probe for positron emission tomography imaging, an Ethisterone derivative [(18) F]EAEF was designed and prepared in high decay-corrected radiochemical yield (30-35%) with good radiochemical purity (>98%). [(18) F]EAEF is a lipophilic tracer (logP = 0.53 +/- 0.06) with very good stability in saline and serum. In the biodistribution study, high radioactivity accumulation of [(18) F]EAEF were found in uterus (5.73 +/- 1.83% ID/g) and ovary (4.05 +/- 0.73% ID/g) at 2 hr postinjection (p.i.), which have high progesterone receptor expression after treated with estradiol, while the muscle background has very low uptake (0.50 +/- 0.17% ID/g). For positron emission tomography imaging, [(18) F]EAEF showed high uptake in progesterone receptor-positive MCF-7 tumor (3.15 +/- 0.07% ID/g at 2 hr p.i.) with good tumor to muscle ratio (2.90), and obvious lower tumor uptakes were observed in MCF-7 with EAEF blocking (1.84 +/- 0.05% ID/g at 2 hr p.i.) or in progesterone receptor-negative MDA-MB-231 tumor (1.80 +/- 0.03% ID/g at 2 hr p.i.). Based on the good stability and specificity of [(18) F]EAEF, it may be a good candidate for imaging progesterone receptor and worth further investigation.
Efficient synthesis of ethisterone glycoconjugate via bis-triazole linkage.[Pubmed:25369262]
Carbohydr Res. 2014 Nov 18;399:2-7.
Synthesis of sugar based triazolyl azido-alcohols was accomplished via one pot click reaction of glycosyl alkynes with epichlorohydrin in aqueous medium. All the developed triazolyl azido-alcohols were further utilized for the synthesis of bis-triazolyl Ethisterone glycoconjugates using CuAAC reaction. The developed triazole-linked Ethisterone glycoconjugates would be crucial in androgen receptor pharmacology and chemical biology.
Luminescent Ag6Au6 heterometallic ethisterone cluster and probe for estrogen receptor alpha.[Pubmed:25580911]
Chemistry. 2015 Mar 9;21(11):4205-8.
A heterometallic cluster [Ag6Au6(Ethisterone)12] of an unprecedented topology was synthesized and characterized. A sensitive and specific probe for estrogen receptor alpha (ERalpha) has been developed for the first time based on the enhancement of the Ag6Au6 luminescence.
