Macro- and micromorphology of the root, stem leaf, infloresence and fruit of Euphorbia peplus L. growing in Egypt

Euphorbia peplus L. belongs to Family Euphorbiaceae which includes about 283 genera with almost 7500 species. They are distributed all over the world mainly tropical countries. Some species of the genus Euphorbia showed antiviral and anticancer activities. It was reported to be used in folkloric medicine as purgative and in treatment of skin diseases, gonorrhea, liver disorders, chest diseases, and gout. Some phytochemical studies have been carried out abroad on different species. The authors carried out phytochemical and biological studies on the studied plant and here in we undertake macro- and micromorphological studies with the aim of finding out the diagnostic features by which the plant could be identified in both entire and powdered forms

Synthesis and antidepressant activity of some novel fluoxetine derivatives

The present work involves the synthesis of three series of novel fluoxetine derivatives in order to evaluate their potential as antidepr ess ants. The first series consists of 1 -methyl- 1-[3-phenyl-3-[4-trifluoromethylphenoxy]propyl]-3-substituted ureas 2a-c and thioureas as their bioisosters 3a-m which were prepared by reacting fluoxetine 1a with different isocyanates and isothiocyanates respectively. The second series N-acyl/aroyl-N-methyl-3-phenyl-3-[4-trifluoromethylphenoxy]-propylamines 4a-d were synthesized by refluxing 1a with acyl/aroyl chloride and trifluoroacetic anhydride. The third one, N-chloroacyl-fluoxetine 5a-c was obtained via the reaction of la with chloroacyl chloride. In addition to a propionitrile derivative 8 which was achieved by refluxing 1a with acrylonitrile. The twenty four final compounds were biologically screened throughout the work for their potential as serotonin reuptake inhibitors by measuring potentiation of 5-HTP induced neurotoxity and some as norepinephrine reuptake inhibitor by measuring yohimbine-induced mortality in mice to calculates-HTP/NE ratio as a parameter for selectivity to inhibit serotonin reuptake. Four compounds [3e, 3h, 3i, 5b] were found to be as potent as fluoxetine

Synthesis of some substituted ureides of expected analgesic and skeletal muscle relaxant activities

The preparation of some substituted ureides containing both the propanediol etherial linkage and the acetanilide moieties in order that these compounds may possibly combine both the analgesic and skeletal muscle relaxant properties, is prescribed
