Synthesis, Radioiodination and Biodistribution Evaluation of 5-(2-amimo-4-styryl pyrimidine-4-yl)-4-methoxybenzofuran-6-ol
This study describes the organic synthesis of 5-(2-amimo-4-styryl pyrimidine-4-yl)-4-methoxy benzofuran-6-ol (SPBF) as an example of a benzofuran derivative used as a new series of amyloid imaging agents. These benzofuran derivatives may be useful amyloid imaging agents for detecting B-amyloid plagues in the brain of Alzheimer’s disease. The precursor is 1-[6-hydroxy-4-methoxybenzofuran-5-yl]-p...
متن کامل2-Benzylsulfanyl-4-pentyl-6-(phenylsulfanyl)pyrimidine-5-carbonitrile
In the title pyrimidine derivative, C(23)H(23)N(3)S(2), the phenyl-sulfanyl and benzyl-sulfanyl benzene rings are orientated away from the carbonitrile group and are twisted out of the plane of the central ring with dihedral angles of 77.66 (6) and 64.73 (5)°, respectively. The n-pentyl group has an extended trans conformation. In the crystal, supra-molecular layers in the ab plane are sustaine...

متن کامل2-[(4-Chlorobenzyl)sulfanyl]-4-(2-methylpropyl)-6-[3-(trifluoromethyl)anilino]pyrimidine-5-carbonitrile
Three independent mol-ecules comprise the asymmetric unit of the title compound, C(23)H(20)ClF(3)N(4)S. The conformations of the mol-ecules are similar with the chloro-benzene and CF(3)-benzene rings almost perpendicular to, and almost co-planar with, the pyrimidinyl ring [range of dihedral angles = 80.36 (13)-88.07 (14) and 11.89 (14)-23.30 (14)°, respectively]; the benzene rings are roughly o...

In the title compound, C(22)H(20)ClN(3)S(2), the S-bound benzene rings are inclined [dihedral angles = 78.13 (10) and 36.70 (9)°] with respect to the pyrimidine ring. The methyl-propyl group occupies a position normal to the pyrimidine ring [N-C-C-C torsion angle = 92.3 (2)°]. In the crystal, supra-molecular layers are formed in the bc plane, being consolidated by C-H⋯π and π-π inter-actions, t...
