Novel 1,3,4-Thiadiazolethiosemicarbazones Derivatives and Their Divalent Cobalt-Complexes: Synthesis, Characterization and Their Efficiencies for Acidic Corrosion Inhibition of Carbon Steel

Two newly synthesized ligands based on 1,3,4-thiadiazolethiosemicarbazone have been isolated by the condensation reaction of 2,3-disubstituted-5-acetyl-1,3,4-thiadiazole derivatives with

Electrochemical Oxidation of 2,5-Dimercapto-1,3,4-thiadiazole on Carbon Electrodes Modified with Ru(III) Schiff Base Complex

The thiol compound 2,5-dimercapto-1,3,4-thiadiazole is a potential cathode material. The redox reactions of the mentioned thiol compound are slow at room temperature but can be enhanced using

Crystal structure, spectroscopic characterization and Hirshfeld surface analysis of trans-diaqua[2,5-bis(pyridin-4-yl)-1,3,4-oxadiazole]dithiocyanatonickel(II)

The NiII atom in the mononuclear title complex has an almost regular octahedral N4O2 coordination geometry and is linked in a three-dimensional network through strong O—H⋯N hydrogen bonds.

Functional Analogues of Salicylic Acid and Their Use in Crop Protection

High-throughput screening methods of chemical libraries allowed the identification of new compounds that do not affect plant growth, and whose mechanisms of action are based on priming of plant defenses, rather than on their direct activation.



The mononuclear nickel(II) complex bis(azido-κN)bis[2,5-bis(pyridin-2-yl)-1,3,4-thiadiazole-κ2 N2 ,N3 ]nickel(II) protects tomato from Verticillium dahliae by inhibiting fungal growth and activating plant defences.

It is demonstrated that the coordination of the ligand with Ni associated with the azide as a coligand resulted in an improvement in its biological activity by both inhibiting the growth of V. dahliae and activating plant defence responses.

Intermolecular magnetic couplings in the dinuclear copper(II) complex mu-chloro-mu-[2,5-bis(2-pyridyl)-1,3,4-thiadiazole] aqua chlorocopper(II) dichlorocopper(II): synthesis, crystal structure, and EPR and magnetic characterization.

It is noteworthy that the behavior of the title compound is original, compared to the systematic in-plane intramolecular antiferromagnetic coupling of other thiadiazole-containing binuclear complexes.

Synthesis, Structural Characterization, Redox and Antimicrobial Studies of Schiff Base Copper(II), Nickel(II), Cobalt(II), Manganese(ii), Zinc(II) and Oxovanadium(ii) Complexes derived from benzil and 2-Aminobenzyl Alcohol

Neutral complexes of Cu(II), Ni(II), Co(II), Mn(II), VO(II) and Zn(II) have been synthesized from the Schiffbase derived from benzil and 2-aminobenzyl alcohol. The structural features have been

Antimicrobial Activity of two Semisynthetic Triterpene Derivatives from Euphorbia Officinarum Latex Against Fungal and Bacterial Phytopathogens

In vitro antimicrobial effect of 3β-acetoxy-norlup-20-one and 3-chloro-4α,14α-dimethyl-5α-cholest-8-ene derivatives from Euphorbia officinarum latex against fungal and bacterial phytopathogens is evaluated, suggesting that they act as fungistatic compounds.

Modulation of tobacco bacterial disease resistance using cytosolic ascorbate peroxidase and Cu,Zn‐superoxide dismutase

It is suggested that cytosolic antioxidant defences have a role in increasing tolerance to the oxidative stress caused by some bacterial pathogens, and resistance of these tobacco lines to wildfire disease seems to be independent of tissue necrosis.

1,3,4‐Thiadiazole and its Derivatives: A Review on Recent Progress in Biological Activities

An attempt has been made with recent research findings on this nucleus, to review the structural modifications on different thiadiazole derivatives for various pharmacological activities.
