In the title compound, C30H28N4O, the central pyrrolidine ring adopts an envelope conformation with the CH2 C atom as the flap. The quinoxaline and indene ring systems are planar, with r.m.s. deviations of 0.0165 and 0.0181 Å, respectively. The pyrrolidine ring mean plane forms dihedral angles of 88.84 (1) and 86.14 (1)° with the quinoxaline and indene ring systems, respectively. A weak intra-m...

1. Eighteen known or possible metabolites of the hepatic carcinogen 4- (or p-) dimethylaminoazobenzene were tested for carcinogenic activity in the rat. Of these compounds only 4-monomethylaminoazobenzene, a known metabolite, proved to be active. Eight compounds, which appear to be metabolites of the dye, were inactive; these included 4-aminoazobenzene, 4'-hydroxy-4-monomethylaminoazobenzene, 4...

Today, the bidentate ligands 3-hydroxypyridin-4-ones (HPOs) as orally active iron chelating agents have been demonstrated to possess potential for treatment of some human diseases such as iron-overload in thalassaemic patients and malaria. In this research, a series of HPOs with different substitutes and position were theoretically invest

In this study, a new series of 6-amino-1,3-dimethyluracil derivative with 6-(3-substituted N-benzylidene)-1,3-dimethyl pyrimidine-2,4-dione-6-yl derivatives which were synthesized by using one pot synthesis. The reaction and different aromatic aldehyde in ethanol yielded Schiff bases (1-6). the subsequent step )1-6) 2-mercaptoacetic acid, 2-chloroacetic acid 2-amino acetic acidn Tetrahydrofuran...
