Kinetic study of the reaction between the cyclopalladated complex [PdCl(C2,N-dmba)(tu)] (dmba = N,N-dimethylbenzylamine, tu = thiourea) and L-cysteine

Diego B. FélixI; Daniela R. TruzziII; Adelino V. de Godoy NettoI; Maria Isabella Z. SoaresI; Gian V. RodriguesI;
José Clayston M. PereiraI,*


The proposed mechanism suggests that cyclometallated Pd(II) complexes can interact with thiols in solution through a series of steps. Overall, this mechanism provides insight into the potential reactivity and selectivity of cyclometallated Pd(II) complexes towards thiols in solution.

Survey of tetracyclines residues in brazilian swine muscle

Vivian FeddernI,*; Carolina RucksII; Vanessa GresslerI; Anildo Cunha JuniorI; Carolina Naves AroeiraIII,IV; Alfredo Marcial Montes NiñoV


Residues of antibiotics used in swine production that have maximum residue limits for muscle and kidney established by legislation. These residues are monitored by chromatographic methods and when compliant results (below maximum residue limits) are obtained, the products might be considered safe to consumers.

Chemometrics and data science are powerful tools for the analysis of chemical data, although they can become highly difficult to execute and analyze owing to a large amount of data. Therefore, free software are strong allies of scientific groups with untapped potential which includes the analysis of data from mixture design experiments.
