摘要:
Applicants describe the synthesis of fluorotamoxifen and iodotamoxifen analogs with the halogen atom positioned on the aliphatic chain of the tamoxifen molecule. The halogenated-tamoxifen derivatives possess superior binding affinities to estrogen receptors of pig uteri compared with tamoxifen. The fluorinated tamoxifens have potential use in imaging estrogen receptors by PET whereas the iodinated tamoxifens have potential use in imaging estrogen receptors by SPECT. Rapid and efficient methods of preparing fluorotamoxifen and iodotamoxifen derivatives with high specific activity are also disclosed. Fluorotamoxifen and iodotamoxifen derivatives may advantageously be used as anti-cancer therapeutic agents to halt estrogen-receptor positive tumors.
摘要:
The synthesis of tamoxifen derivatives, most particularly halo, haloalkyl and hydroxy tamoxifen derivatives, wherein the native tamoxifen molecule includes a substituted chemical group positioned on the aliphatic chain of the tamoxifen molecule, is provided. Methods for imaging estrogen receptors using the tamoxifen derivatives of the invention are also described. The aliphatic chain substituted tamoxifen derivatives of the invention possess greater estrogen receptor binding affinities and more potent tumor cell inhibiting activity than native tamoxifen or tamoxifen derivatives substituted at other locations on the molecule (i.e., non-aliphatic chain substituted tamoxifen, phenolic-ring substituted tamoxifen). Examples of the halogenated tamoxifen derivatives of the invention include chloro-, bromo-, iodo- and fluoro-tamoxifen derivatives, and their corresponding lower alkyl halogenated forms.
