Lipophilicity Studies on Thiosemicarbazide Derivatives [PDF]
Molecules, 2017 The lipophilicity of two series of thiosemicarbazide derivatives was assessed by the RP-HPLC method with the RP-18 chromatographic column and the methanol–water mixture as the mobile phase. Distribution coefficients logPHPLC were compared to calculated values generated by commonly used AClogP software and quantum chemical calculations.

Coumarinyl Thiosemicarbazides as Antimicrobial Agents [PDF]
Pharmaceutical Chemistry Journal, 2018 A two series of coumarinyl thiosemicarbazides were synthesized. One series derived from coumarin core substituted in position 7 and another from coumarin core substituted in position 4. All compounds were obtained in reaction of corresponding hydrazide and various isothiocyanates.

Thiosemicarbazide Toxicity in Mice.
Experimental Biology and Medicine, 1952 Summary1. Fatal convulsions follow the administration of doses of 20 mg of thiosemicarbazide (TSC)/kg or more to mice. 2. Semicarbazide is approximately 1/20 as toxic as thiosemicarbazide, while aminoguanidine produces no toxic symptoms at a dose of 650 mg/kg. 3.
