Abstract
The synthesis and biological studies of a series of Pd(II)dipyrrinato complexes are reported. The thiogalactosyl and/or oligoethyleneglycol moieties were linked with themeso-aryl rings of the Pd(II)dipyrrinato complexes. The Pd(II)dipyrrinato complexes were characterized by MASS, IR, UV-Vis, and NMR spectroscopic techniques. Single crystal X-ray structure of the homoleptic Pd(II)dipyrrinato complex (Pd1) revealed typical square planar geometry around the metal center. The anti-bacterial studies of Pd(II) dipyrrinato complexes were performed on theM. Tuberculosis H37Rv and M. Bovis BCG strains and complex Pd4 showed excellent anti-TB activity with MIC values of 25 [Formula: see text]M and 12.5 [Formula: see text]M, respectively. The ease of synthesis and good MIC values of Pd(II)dipyrrinato complexes make them promising candidates for anti-TB activity.
