New Complexes Of Organotin(Iv) 2-(N-Maleoylamino)-2-Methylpropanoate: Synthesis, Spectroscopic Characterization And Biological Activity, Sajjad Ahmad, Saqib Ali, Saira Shahzadi, Fiaz Ahmed, Khalid Mohammed Khan
Turkish Journal of Chemistry
Organotin(IV) complexes of 2-(N-maleoylamino)-2-methylpropanoate were prepared by treating the ligand acid with diorganotin dichloride and triorganotin chloride in 1:2 and 1:1 molar ratios, respectively. These reactions proceeded smoothly to completion and the complexes formed were characterized by elemental analysis, infrared, multinuclear NMR (^1H, ^{13}C, ^{119}Sn) and mass spectrometry. The biological activities of the tin complexes were studied by screening the compounds against various animal and plant pathogens. These results show that triorganotin(IV) carboxylates are more active against the animal and plant pathogens tested as compared to diorganotin dicarboxylates.

Cellular Functions Of The 26s Proteasome, Azmi̇ Yerli̇kaya
Cellular Functions Of The 26s Proteasome, Azmi̇ Yerli̇kaya
Turkish Journal of Biology
The 26S proteasome plays a critical role in many cellular processes by degrading a wide range of both short-lived and long-lived proteins. In this review, proteasome structure and the mechanisms of substrates targeting to the 26S proteasome are described. In addition, this review focuses on the cellular functions that are affected after inhibition of the proteasome, including immune-response, cell-cycle, and transcription. The proteasome is involved in these cellular processes because it degrades numerous short-lived proteins and regulatory proteins that control these cellular functions. Even though it is known that inhibition of the 26S proteasome results in the induction of the …

The Mechanism Of Inhibition Of Human Erythrocyte Catalase By Azide, Yasemi̇n Aksoy, Mevhi̇be Balk, Hamdi̇ Öğüş, Nazmi̇ Özer
Turkish Journal of Biology
In order to elucidate the kinetic mechanism of human erythrocyte catalase a well-known substrate, H_2O_2 and inhibitor azide were used. The catalase-mediated conversion of H_2O_2 to H_2O and O_2, in the presence and absence of azide, was studied in 50 mM phosphate buffer pH 7.0 at 37 ºC under conditions where the peroxidation side reaction (RH_2 + H_2O_2 R + 2H_2O) is negligible ([H_2O_2] =< 25 mM; assay time, 10 s). The kinetics conformed to the Michaelis-Menten model. Lineweaver-Burk plots for H_2O_2 at different fixed concentrations of azide were linear and intersected on the abscissa indicating a noncompetitive or irreversible type of inhibition. To identify the inhibition type Vm vs. [E] plots were constructed at different [N_3-]. The plots were linear and converged at the origin, indicating that N_3- is a noncompetitive inhibitor. Using a non-linear curve-fitting program, the kinetic parameters were calculated. The K_m value for H_2O_2, and the K_i value for azide were found to be 10.97 ± 1.46 mM and 1.107 ± 0.093 µM, respectively.
