There has been substantial attention in the expansion of new thiosemicarbazide derivatives with diverse biological activities in recent years. Therefore, many scientists have prepared this class of derivatives as target structures and estimated their biological activities. Recent research mainly des...

Two new nickel (II) substituted thiosemicarbazone Schiff base complexes [Ni(meph)2] (1) [where H2meph = (2E)-N-methyl-2-[1-(pyridin-2-yl)ethylidene]hydrazine-1-carbothioamide] and [Ni(hmm)2](NO3)2·2H2O (2) [where H2hmm = (2E)-2-[(2-hydroxyphenyl)methylidene]-N-methylhydrazine-1-carbothioamide] have ...

Compounds targeting bacterial topoisomerases are of interest for the development of antibacterial agents. Our previous studies culminated in the synthesis and characterization of small-molecular weight thiosemicarbazides as the initial prototypes of a novel class of gyrase and topoisomerase IV inhib...

This review paper focuses on the different synthetic methodologies that researchers have adopted to synthesize various thiosemicarbazide derivatives with different biological activities of synthesized compounds in the last 20 years. Most of the investigations available in the literature are directed...

A thiosemicarbazide derivative as (E)-4-ethyl-1-(1-(naphthalen-1-yl) ethylidene) thiosemicarbazide (HAN) was synthesized then characterized to prepare [Co(HAN)Cl2·(H2O)2], [Ni(HAN)Cl2·(H2O)2]. H2O, and [Cd(HAN)Cl2] complexes. According to spectral and analytical data we could confirm the neutral bid...

Forty-five derivatives of thiosemicarbazide were synthesized, and their antibacterial activity against Gram-positive and Gram-negative bacteria was evaluated. Some of the described compounds exhibited interesting activity against reference strains of Gram-positive bacteria, whereas only two derivati...

Synthesis of new antimicrobial compounds is need of the hour due to prevalence of resistance to antibacterial agents. Different pharmacological activities like, anticancer, antimicrobial, antifungal, anticonvulsant, antimalarial, analgesic and anti-inflammatory are shown by mannich bases and thiosem...

In this study, eight new Schiff base derivatives (2a-h) were synthesized and their inhibition activities against Acetylcholinesterase (AChE), Butyrylcholinesterase (BChE), α-Glucosidase and Lactoperoxidase (LPO) were investigated. Structures of the synthesized compounds were characterized using 1H a...
