Synthesis of a novel planar-chiral nido-carborane amino acid [PDF]

Russian Chemical Bulletin, 2021
The deboronation of enantiomers of planar-chiral benzyl (3-formamido-1,2-dicarba-closo-dodecaboran-1-yl)acetate gave the individual (RP)- and (SP)-enantiomers (ee > 98%) of a new amino acid containing a nido-carborane fragment, (3-ammonio-7,8-dicarba ...

Dicarba-closo-dodecaborane(12) derivatives of phosphonium salts: easy formation of nido-carborane phosphonium zwitterions [PDF]

Dalton Transactions, 2007
The first examples of arylphosphonium salts containing a dicarba-closo-dodecaborane(12) (closo-carborane) are reported; in contrast to the 1,12-carborane derivative, the 1,2- and 1,7-isomers undergo a facile deboronation reaction in polar solvents to ...

Nido-carborane encapsulated by BODIPY zwitterionic polymers: Synthesis, photophysical properties and cell imaging

Journal of Saudi Chemical Society, 2021
Carborane encapsulation was visualized by using fluoroboropyrrole (BODIPY) zwitterionic polymer as fluorescence marker. Firstly, a water-soluble fluorescent probe carrier was prepared by combining the BODIPY derivatives with poly (carboxybetaine ...

A Redox-Tunable Carborane Crown: Toward Highly Selective Electrochemical Lithium Capture. [PDF]

Chemistry
Electrochemical reduction transforms a new carborane–crown into a potent 2e− reduced nido anion with a redox‐tunable cavity that captures Li⁺ selectively over Na⁺ and K⁺. The coupling of electronic control and size‐matched binding offers a blueprint for selective, rapid lithium recovery for next‐generation direct lithium extraction. Abstract Lithium is

Development of Carborane-Based Halogenated Naphthyridinone-Analogues as Cannabinoid Receptor Type 2 (CB₂R) Ligands. [PDF]

ChemMedChem
There is no suitable radioligand for positron emission tomography imaging of CB2R overexpression for routine clinical usage. Herein, the synthesis, characterization, binding affinity, and docking studies of carborane‐based halo‐substituted naphthyridinone derivatives as CB2R ligands are presented.

Water-soluble BODIPY-nido-carborane nanoparticles applied to biocompatibility tumor cell imaging [PDF]

Photochemical & Photobiological Sciences, 2022
In this article, o-carborane has a high boron content, high hydrophobicity, and good chemical stability. It has been widely used in the fields of biology and medicine, especially in the application of boron neutron capture therapy (BNCT). However, o-carborane is a fat-soluble compound, its hydrophobicity is too strong, and its bioavailability is poor ...

Carboranes as unique pharmacophores in antitumor medicinal chemistry

Molecular Therapy: Oncolytics, 2022
Carborane is a carbon-boron molecular cluster that can be viewed as a 3D analog of benzene. It features special physical and chemical properties, and thus has the potential to serve as a new type of pharmacophore for drug design and discovery.

Carborane-Based Analogs of Celecoxib and Flurbiprofen, their COX Inhibition Potential, and COX Selectivity Index. [PDF]

ChemMedChem
Eight nido‐ and ortho‐carborane compounds based on celecoxib and flurbiprofen were synthesized and their COX inhibition was determined. The deboronation of the di‐substituted celecoxib derivative results in a switch from COX‐1 inhibitory preference to COX‐2 inhibition.
