Monoamine Oxidase and Cholinesterase Inhibition Profiles of Semicarbazone and Thiosemicarbazone Derivatives. [PDF]

Chem Biodivers
Thiosemicarbazones generally show higher MAO‐B inhibitory potential than their corresponding semicarbazones, and particularly T6 is the most potent, which contains R = H and X = S in its Tail Unit, with an IC50 value of 6.45 µM with SI of 3.6. ABSTRACT Twenty semicarbazone and thiosemicarbazone derivatives (T1–T20) were synthesized and evaluated for ...

Evolution of Thiosemicarbazones: From First- to Second-Generation Metal Chelators and Their Reactive Oxygen Species-Mediated Effects in Melanoma. [PDF]

ChemistryOpen
Thiosemicarbazones (TSC) have demonstrated promise as new chemotherapeutic agents against melanoma in both in vitro and In vivo studies. TSC are powerful metal coordinating agents, coordinating transition metal ions such as zinc, copper and iron in multiple oxidation states. It is this metal coordination that imparts the anticancer activity.
