starting from readily available 2-substituted-4-methylthiazole-5-carboxylic acid hydrazide (1), the title compounds were prepared. the reaction of compound 1 (r=ch3) with formic acid yielded 1-(formyl)-2-(2,4-dimethylthiazole-5-carboxyl) hydrazine (2). refluxing the latter with phosphorous pentasulfide in xylene afforded compound 3, the reaction of compound 2 with phosphorous pentoxide afforded...

three native turkish medicinal and aromatic plants (artemisia absinthum, artemisia santonicum and saponaria officinalis) were investigated to analyze their antioxidant activity, total phenolic content and antimicrobial activity. their total antioxidant activity was determined by using a β-carotene bleaching assay and their antimicrobial activity was determined by utilizing an agar disc diffusio...

Fractions obtained from partitioning of aerial methanolic extract of Euphorbia Aellenii with chloroform (E2), ethyl acetate (E3), n-butanol (E4) and water (E5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. Sample E2 appeared to have significant phytotoxic activity. In the insecticidal screening study o...
