Synthesis, DFT Calculation and Biological Activity of Some Organotellurium Compounds Containing Azomethine Group

Orbital: The Electronic Journal of Chemistry, 2019
The reaction of (4-amino-2,3-dichlorophenyl)mercury (II) chloride with 3,4-dihydroxy benzaldehyde produce the organomercury compound 1 in 82% yield. Tellurated of 1 with tellurium (IV) tetrabromide gave the tellurium (IV) tribromide Schiff base compound ...

Crystallographic, DFT and docking (cathepsin B) studies on an organotellurium(IV) compound [PDF]

, 2016
Some biologically active organotellurium compounds exhibit inhibitory potency against cathepsin B. In this study, an alkyl derivative, viz. [CH3(CH2)2C(I)=C(H)](nBu)TeI2, 1, has been structurally characterised by X-ray crystallography and shown to be ...

Polymerization‐induced self‐assembly for drug delivery: A critical appraisal

Journal of Polymer Science, Volume 61, Issue 24, Page 3186-3210, 15 December 2023., 2023
Abstract Polymerization‐induced self‐assembly (PISA) with (in situ) encapsulation of (therapeutic) cargo has proven to be an efficient preparation method for loaded polymeric micelles and polymersomes, thereby presenting significant opportunities in the field of drug delivery.

Chalcogen Bonding Catalysis: Tellurium, the Last Frontier?

Chemistry – A European Journal, Volume 29, Issue 69, December 11, 2023., 2023
This review highlights the importance of chalcogen bonding in organic synthesis through a compilation of tellurium derivatives used up‐to‐now in catalysis. These powerful chalcogen bond donors were shown to activate numerous kind of substrates by non‐covalent interaction with functional groups such as chlorides, carbonyls, imines, epoxides, alcohols ...

Responsive materials based on coordination bonds

Responsive Materials, Volume 1, Issue 2, November 2023., 2023
Distinct from the previous reviews on responsive materials, this review highlights the recent advances in responsive materials based solely on coordination bonds. The responsive materials based on coordination bonds are categorized and summarized by the type of external stimuli, including thermo‐stimulus, photo‐stimulus, electro‐stimulus, mechano ...

Cyclization Reactions Involving 2-Aminoarenetellurols and Derivatives of α,β-Unsaturated Carboxylic Acids

Heteroatom Chemistry, 2021
The reductive cyclization of arenetellurols carrying α,β-unsaturated amide functionalities in the ortho position was investigated. Conceptually, such compounds can form 1,3-tellurazoles without the involvement of the unsaturation in the ring closure ...

Review

, 2020
The chalcogen elements oxygen, sulfur, and selenium are essential constituents of side chain functions of natural amino acids. Conversely, no structural and biological function has been discovered so far for the heavier and more metallic tellurium ...

2-chlorovinyl tellurium dihalides, (p-tol)Te[C(H)=C(Cl)Ph]X2 for X = Cl, Br and I: variable coordination environments, supramolecular structures and docking studies in cathepsin B [PDF]

, 2010
Crystallography shows that the Te atom in each of (p-tol)Te[C(H)=C(Cl)Ph]X2, for X = Cl (1), Br (2) and I (3), is within a distorted Ψ-pentagonal bipyramidal geometry.
