Abstract:
The abilities of five Pd complexes, including Pd(bipy)Cl2, Pd(phen)Cl2, [Pd(dien)Cl]Cl, trans-Pd(NH3)2Cl2 and cis-Pd(NH3)2Cl2, to inhibit protein splicing of Mycobacterium tuberculosis RecA intein have been evaluated. The results showed that trans-Pd(NH3)2Cl2 has the best inhibition efficiency(IC50=3.3×10-5 mol/L). Competition experiments suggest that the inhibition of protein splicing can be ascribed to the interaction between Pd complexes and the first residue(cysteine) of RecA intein. Furthermore, the difference in the fluorescence quenching of ΔΔIhh-CM by Pd complexes is most likely due to the ligand steric hindrance.
