The Preparation and Pyrolysis of 2-methyl-4-alkyl(aryl)semicarbazides [PDF]
, 1969 The purpose of the research described in this thesis was twofold. Attempts were made to prepare several 4-alkyl (aryl)-2-methylsemicarbazides, many of which had not been prepared previously.

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.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 ...

Enantioselective Growth of Chiral Serine‐Induced β‐Ag2Se Crystals from an Organoselenium Compound
Advanced Functional Materials, Volume 36, Issue 22, 16 March 2026.Chiral amino acids direct the enantioselective crystallization of β‐Ag2Se nanocrystals from an organoselenium precursor. L‐ and D‐serine induce distinct morphologies and opposite homochiral adsorption preferences, transferring molecular handedness into the inorganic lattice.

Some semicarbazide derivatives and their antimicrobial activity
Communications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1993 Various semicarbazides and thiosemicarbazides (1-5) and their cyclised products, triazoles, oxadiazoles and thiadiazoles (6-9) have been reported to possess antibacterial, antitubercular and antifungal activities. Based on these findings it w as of interest to prepare some new arylsemicarbazide and arylthiosemicarbazide derivatives and to evaluate ...
