Structure-activity relationship study towards non-peptidic positron emission tomography (PET) radiotracer for gastrin releasing peptide receptors: Development of [18F] (S)-3-(1H-indol-3-yl)-N-[1-[5-(2-fluoroethoxy)pyridin-2-yl]cyclohexylmethyl]-2-methyl-2-[3-(4-nitrophenyl)ureido]propionamide
摘要:
Gastrin-releasing peptide receptors (GRP-Rs, also known as bombesin 2 receptors) are overexpressed in a variety of human cancers, including prostate cancer, and therefore they represent a promising target for in vivo imaging of tumors using positron emission tomography (PET). Structural modifications of the nonpeptidic GRP-R antagonist PD-176252 ((S)-1a) led to the identification of the fluorinated analog (S)-3(1H-indol-3-yl)-N-[1-[5-(2-fluoroethoxy) pyridin-2-yl] cyclohexylmethyl]-2-methyl-2-[3-(4-nitrophenyl) ureido] propionamide ((S)-1m) that showed high affinity and antagonistic properties for GRP-R. This antagonist was stable in rat plasma and towards microsomal oxidative metabolism in vitro. (S)-1m was successfully radiolabeled with fluorine-18 through a conventional radiochemistry procedure. [F-18] (S)-1m showed high affinity and displaceable interaction for GRP-Rs in PC3 cells in vitro. (C) 2016 Elsevier Ltd. All rights reserved.

The present invention relates to a N2-(2-methoxyphenyl)pyrimidine derivative, a preparation method thereof, and a pharmaceutical composition for the prevention or treatment of cancer comprising the same as an active ingredient. The N2-(2-methoxyphenyl)pyrimidine derivative, the optical isomer thereof, or the pharmaceutically acceptable salt thereof of the present invention is very effective in suppressing anaplastic lymphoma kinase (ALK) activity and as a result it can improve the effectiveness of treatment on cancer cells having anaplastic lymphoma kinase (ALK) fusion proteins such as EML4-ALK and NPM-ALK, so that it can be effectively used as a pharmaceutical composition for preventing or treating cancer.
