In this work 6-fuloro-2-aminobenzothazol compound (R1) have been prepared from the reaction of aniline with appropriate potassium thiocyanate in presence cooled glacial acetic acid in such a way to temperature not exceeded above room temperature, Solution of 1.6ml of bromine in 6ml of glacial acetic acid, the reaction 6-fuloro-2-aminobenzothazol of with Hydrazine hydrate 6-fluoro-2-hydrazineylbenzo thiazole yielded compounds (R2). The research included synthesis of schiff base from the reaction of with appropriate aromatic aldehydes in presence of glacial acetic acidyieldeds compounds (R3-R7) 2-(2- benzylidenehydrazineyl)-6-chlorobenzo thiazole, and synthesis of thiazolidinone from the reaction of thioglycolic acid with schiff base,yieldeds compounds (R8-R12) chloro-N-(5-phenyl-2,5-dihydro-tetrazol-1- yl) benzo thiazol-2. The prepared compounds have been characterized by melting points and some physical properties besides the FT-IR, H-NMR spectra and quantitative analysis of elements (C.H.N.). The purity for these compounds was checked by TLC. The study is showed biological activity for chemical compounds, at three concentrations (10-2,10-3,10-4) mg/ml The minimum inhibitory concentration [MIC] have been determined with the reference of stander drugs the results showed that the thiazolidinone derivatives are better than growth of both types of bacteria gram-positive and gram–negative compared to drug, and evaluation of laser efficacy.

bstract. In this work, substituted 2-amino benzothiazoles (W1-4 ) were synthesized from, the reaction of aniline substituted with potassium thiocyanate in presence of broomin. The selective liquid phase N-alkylation of substituted 2- amino benzothiazoles by1,4-bis (Bromo methyl) benzene using Al2O3–OK as a catalyst in the presence of acetonitrile at room temperature (30 C) is described. synthesis of Al2O3–OK catalyst from the reaction of potassium nitrate with aluminum (III) oxide yielded compounds(W5 -8 ) .All these synthesized compounds were characterized on the basis of their by (IR and 1H-NMR, 13C-NMR, CHN, TLC) and physical methods, the study is showed biological activity for chemical compound, at three concentrations( 0.01,0.001,0.0001) mg/ml The minimum inhibitory concentration [MIC] have been determined with the reference of stander drugs. The rest of the substituted 2-amino benzothiazole derivatives showed moderate to good antibacterial activity, whereas the N-alkylation derivatives showed mild to low antibacterial activity. Thus, it is concluded from the screening results that benzothiazole derivatives were most effective against all microorganisms at a concentration of 50 mg/mL compared to drug.

the reaction between 4-Bromo-2-fluoro aniline with potassium thiocyanate in presence of liquid brome. Synthesis of Schiff base from reaction 6-Bromo-4-fluoro-2-aminobenzothiazole (w2-W5). The reaction of chloroactyl chloride with Schiff base yielded compounds (w6-9) azetidine. All the new compounds have been characterized using infrared spectroscopy (IR), proton nuclear magnetic resonance (H1-NMR) and physical methods. The antibacterial activity has beentested in vitro by the disk diffusion assay method against two kinds of bacteria gram positiveand gram negative. The minimum inhibitory concentration [MIC] have been determined withthe reference of stander drugs, the results showed that the azetidine derivatives are betterthan growth of both types of bacteria (gram-positive and germ–negative compared to drug

In this work, new 2-amino benzothiazole (W1) were synthesized from the reaction between aniline substituted with potassium thiocyanate in presence of broom. (W1) reaction with phenol substituted to give azo dyes compound (W2-W5). Polyacrylic acid was converted into poly acryloyl chloride by reaction poly acrylic acid with thionyl chloride was dissolved in acetonitrile with reaction different organic compounds. (W1-9) characterized were using (IR) and (HNMR-CNMR-CHN–TLC) techniques and the analysis revealed biological activity for chemical compounds at three concentrations (0.01, 0.001, 0.0001) mg/ml. (MIC) was calculated using standard drugs as a comparison. The findings revealed that azo derivatives outperformed medication in inhibiting the growth of gram negative & positive bacteria.
