Four new carboxylates complexes with general formula R2SnL2 and R3SnL, where R = n-butyl (1, 3), methyl (2, 4) L 4-Chlorophenoxyacetate, were synthesized in significant yields. FT-IR analysis revealed a chelating (1 2) bridging bidentate (3 coordination modes for the carboxylate ligand solid state which was further confirmed by single crystal X-ray of complex 4. The NMR data (1H, 13C 119Sn) higher number around tin center compared to R3SnL 4). A close matching observed between experimental...

Camel is continually exposed to stressful desert environment that enhances generation of reactive oxygen species, including hydrogen peroxide (H2O2). Catalase plays an important role in detoxification H2O2. A highly active catalase from camel kidney was purified homogeneity, with a specific activity 1,774,392 U/mg protein, using ion exchange and metal chelate affinity chromatography. The molecular weight the enzyme 268 kDa consisting four identical subunits 63 kDa. showed higher optimum...
