Heavy atom effects in the Paternò–Büchi reaction of pyrimidine derivatives with 4,4’-disubstituted benzophenones
The regioselectivity and the photochemical efficiency were investigated in the Paternò-Büchi reaction of 1,3-dimethylthymine (DMT) and 1,3-dimethyluracil (DMU) with benzophenone (1b) and some 4,4'-disubstituted derivatives (dimethoxy (1a), difluoro (1c), dichloro (1d), dibromo (1e) and dicyano benzophenone (1f)) that gives rise to two regioisomeric oxetanes, 2 and 3. The regioselectivity (the r...
متن کامل4,6-Dimethyl-2-(naphthalen-1-yl)pyrimidine
The asymmetric unit of the title compound, C(16)H(14)N(2), contains two independent mol-ecules in which the dihedral angles between the pyrimidine and naphthaline rings are 38.20 (5) and 39.35 (5)°. Inter-molecular C-H⋯π contacts and π-π stacking inter-actions [centroid-centroid distances = 3.766 (1) and 3.792 (1) Å] are present in the crystal structure.
متن کاملReceptor Tyrosine Kinase Inhibitory Activities and Molecular Docking Studies of Some Pyrrolo[2,3-d]pyrimidine Derivatives
In this study, we aimed to determine VEGFR-2, EGFR and PDGFR-β tyrosine kinase inhibitory activities of some pyrrolo[2,3-d]pyrimidine derivatives previously synthesized and showed potent cytotoxic and apoptotic effects against several cancer cell lines by our group and to evaluate the relationships between inhibitory activities and binding properties of the active compounds by molecular docking...
متن کاملFree radical scavenging properties of pyrimidine derivatives
Free radicals are well known for playing a dual role in our body- deleterious as well as beneficial. It includes a metabolic pathway for its generation. Oxidative stress in our body occurs due to excessive generation of free radicals and reduced level of antioxidants, but at low concentrations, these radicals help to perform normal physiological functions of the body. Scientific evidence sugges...
متن کاملPharmacological activities of some triazinopyrazolothieno pyrimidine derivatives.
Triazinopyrazolothieno pyrimidine derivatives 1-5 were evaluated for their anti-inflammatory, analgesic and anticancer activities and acute toxicity. Anti-inflammatory activity of the compounds was studied using the carrageenan test. All tested compounds showed analgesic activity, 3-methoxycarbonyl-4,6-dimethyl-8-[(N-methylindolyl)methyl] pyrimido [5',4':4,5]thieno [3',2'-3,4]pyrazolo [5,1-c]tr...
