چکیده
We show that the blow-up of P in n points on a line has finitely generated Cox ring. We give explicit generators for the ring and calculate its defining ideal of relations.

On the Cox Ring of P2 Blown up in Several Points on a Line
We show that the surface X, which is a blow-up of P in n points on a line, has finitely generated Cox ring. We give explicit generators for the ring and calculate its defining ideal of relations.

A group of regioisomeric 5-oxo-1,4,5,6,7,8 hexahydroquinoline derivatives possessing a COX-2 SO2Me pharmacophore at the para position of the C-2 or C-4 phenyl ring, in conjunction with a C-4 or C-2 phenyl (4-H) or substituted-phenyl ring (4-F,4-Cl,4-Br,4-OMe,4-Me, 4-NO2), were designed for evaluation as selective cyclooxygenase-2 (COX-2) inhibitors. These target 5-oxo-1,4,5,6,7,8 hexahydroquino...

متن کاملDesign and Synthesis of New Biarylhydrazides Possessing an Azido Pharmacophore as Selective COX-2 Inhibitors
A group of 1,3-biarylhydrazide derivatives possessing a COX-2 azido pharmacophore at the Para- position of the C-1 phenyl ring in conjunction with a N-3 phenyl or substituted-phenyl ring (4-F,4-Cl,4-OMe) were designed and synthesized based on nucleophilic substitution reaction. A molecular modelling study of these compounds showed that the designed molecules were well bound with the active site...
متن کاملEvaluation of cytotoxic effect of zinc on Raji cell line by a florescent technique
Background: Zinc has important effects on human health, especially on structural and functional activities of the immune system. This study was carried out to examine the in vitro cytotoxic effects of zinc on Raji cell line. Materials and Methods: The cell line was exposed to different concentrations of zinc followed by incubation (37°C, 5% CO2) at various time points (12 to 72 hrs).Viabil...
