Ghandhi, Laura H. D.; Bidula, Stefan; Pask, Christopher M.; Lord, Rianne M.; McGowan, Patrick C. published the article 《Bis(N-picolinamido)cobalt(II) Complexes Display Antifungal Activity toward Candida albicans and Aspergillus fumigatus》. Keywords: Candida Aspergillus bis N picolinamido cobalt II antifungal; Aspergillus fumigatus; Bioinorganic Chemistry; Candida albicans; Cobalt Complexes; Picolinamide ligands.They researched the compound: Picolinamide( cas:1452-77-3 ).Formula: C6H6N2O. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1452-77-3) here.
This report highlights the synthesis and characterization of ten new bis(N-picolinamido)cobalt(II) complexes of the type [(L)2CoX2]0/2+, whereby L=N-picolinamide ligand and X=diisothiocyanato (-NCS), dichlorido (-Cl) or diaqua (-OH2) ligands. Single crystal X-ray (SC-XRD) anal. for nine of the structures are reported and confirm the picolinamide ligand is bound to the Co(II) center through a neutral N,O binding mode. With the addition of powder X-ray diffraction (PXRD), we have confirmed the cis and trans ligand arrangements of each complex. All complexes were screened against several fungal species and show increased antifungal activity. Notably, these complexes had significant activity against strains of Candida albicans and Aspergillus fumigatus, with several compounds exhibiting growth inhibition of >80 %, and onecompound inhibiting Aspergillus fumigatus hyphal growth by >90 %. Conversely, no antifungal activity was exhibited toward Cryptococcus neoformans and no cytotoxicity towards mammalian cell lines.
I hope my short article helps more people learn about this compound(Picolinamide)Formula: C6H6N2O. Apart from the compound(1452-77-3), you can read my other articles to know other related compounds.
