In an effort to establish new pyrroles and pyrrolo[2,3-d] pyrimidines with improved antimicrobial activity we report here the synthesis and in vitro microbiological evaluation of a series of pyrrole derivatives. A series of new 2-aminopyrrole-3-carbonitriles (1a-d) were synthesized from the reaction of benzoin, primary aromatic amines and malononitrile, from which a number of pyrrole derivative...
The title compound, C(28)H(26)O, was synthesized by condensation of diphenyl-methyl-lithium and ethyl acetate. In one diphenyl-methyl group, the two benzene rings are rotated by 65.0 (3)° with respect to each other, while in the other diphenyl-methyl group, the dihedral angle between the two benzene rings is 84.1 (3)°.
The complete mol-ecule of the title compound, C(12)H(10)ClO(2)PS, is generated by crystallographic mirror symmetry, with the P, S and Cl atoms lying on the mirror plane. The resulting PO(2)SCl tetra-hedron is significantly distorted [O-P-O = 96.79 (9)°]. The crystal packing exhibits no directional inter-actions.
BACKGROUND Special diphenyl-pyrazole compounds and in particular anle138b were found to reduce the progression of prion and Parkinson's disease in animal models. The therapeutic impact of these compounds was attributed to the modulation of α-synuclein and prion-protein aggregation related to these diseases. METHODS Photophysical and photochemical properties of the diphenyl-pyrazole compounds ...
