ABSTRACT
 
 Isolation of essential oil by steam and water distillation method, identification GC-MS antibacterial activity test against akway bark (D. arfakensis Gibbs) have been carried out. The results showed that the component was composed 142 compounds, which were dominated 10 components. ten suspected components are: 4,5-dimethyl-1-heksen (4,15%); 4-methyl-1-ol-3-penten (3,93%); ...

ab initio calculations at the density functional theory (dft) and the second-order møller−plessetperturbation theory levels with 6-31+g(d), 6-31g(d) basis sets for non-metal atoms and lanl2dzfor metal have been performed for the adsorption of dimethyl methylphosphonate (dmmp) on znoby gaussisn 98 program. the calculated rotational constants by b3lyp/6-31g(d) are in moreagreement with the experi...

N-Oxidation of 1,4-dihydro-2,6-dimethyl-1- phenyliminopyridine (7) with several peracids was attempted. The main compound obtained was l-phenyl- 2,6-dimethyl-4-pyridone (8), instead of the expected N-oxide (2). The reaction of phenylhydroxylamine with dimthylrnethoxypyroxonium perchlorate, however, successfully gave the N-oxide (3), which belongs to a class of nitrones in which the diazomet...

Mice were treated with ketoconazole with and without dimethyl sulfoxide. Concentrations of ketoconazole at 3 and 5 h after treatment were significantly higher in serum (P less than 0.05) and brain tissue homogenate (P less than 0.01) of mice treated with dimethyl sulfoxide than in those of mice not treated with dimethyl sulfoxide.

A Novel compound namely N-(Nicotinoyl) 3,5 dimethyl-4-(N-4-sulfamoylazo)-1,2-diazole has been synthesised by two step processes. Synthesis of N-4-sulphamoylphenylhydrazono-3,5-dimethyl propane1,3-dione and sulphonamide, which interacting with Nicotinic acid hydrazide to form final compound. The newely synthesised compound N-(nicotinoyl)-3,5-dimethyl 4-(N-4-sulfamoyl phenyl azo) 1,2-diazoles was...
