Cycloadditions of cyclohexynes and cyclopentyne. [PDF]

open access: yes, 2014
We report the strategic use of cyclohexyne and the more elusive intermediate, cyclopentyne, as a tool for the synthesis of new heterocyclic compounds. Experimental and computational studies of a 3-substituted cyclohexyne are also described.

Further Structure‐Activity Relationship of G Protein‐Gated Inwardly Rectifying Potassium Channels 1/2 Activators: Synthesis and Biological Characterization of In Vitro Tool Compounds

open access: yesChemMedChem, EarlyView.
Work presented here details the design and characterize novel G protein‐gated inwardly rectifying potassium channels (GIRK)1/2 activators. A new 4,4‐difluorocyclohexylpyrazole have been identified that confers improved potency and selectivity for GIRK1/2 versus GIRK1/4.

Is Mycobacterial InhA a Suitable Target for Rational Drug Design?

open access: yesChemMedChem, EarlyView.
InhA is the target of isoniazid, a first‐line antituberculosis drug. Isoniazid is, in fact, a prodrug that needs to be activated. Researchers are trying to develop direct inhibitors of InhA. This includes the resolution of crystallographic structures. The Protein Data Bank contains over a hundred InhA structures.

Combined experimental and computational investigations of rhodium-catalysed C-H functionalisation of pyrazoles with alkenes [PDF]

open access: yes, 2014
Detailed experimental and computational studies have been carried out on the oxidative coupling of the alkenes C(2)H(3)Y (Y=CO(2)Me (a), Ph (b), C(O)Me (c)) with 3-aryl-5-R-pyrazoles (R=Me (1 a), Ph (1 b), CF(3) (1 c)) using a [Rh(MeCN)(3)Cp*][PF(6)](2 ...

Synthesis and Biological Evaluation of Bicyclic Pyrazolines with Promising Antimicrobial Activities

open access: yesChemMedChem, EarlyView.
Continuous flow technology is exploited for the generation of bicyclic pyrazolines via photo‐click reactions. These heterocyclic species contain a valuable 3D scaffold along with a polar succinimide moiety. Subsequent antimicrobial testing reveals that halogenated moieties such as chlorine atoms and trifluoromethoxy groups enhance the potency of these ...

Development of Carborane‐Based Halogenated Naphthyridinone‐Analoga as Cannabinoid Receptor Type 2 (CB2R) Ligands

open access: yesChemMedChem, Accepted Article.
The cannabinoid receptor type 2 (CB2R) is overexpressed under pathological conditions. PET is a suitable non‐invasive imaging technique for diagnosing disease states, but requires a radiotracer that binds to CB2R with high affinity and selectivity. Currently, there is no suitable candidate routinely used in the clinics.

A Mechanochemical Route for the Synthesis of Diphenyleneiodonium Salts and the Estimation of Their Relative Solid‐State Reactivities

open access: yesChemistry–Methods, EarlyView.
An efficient mechanochemical route for diphenyleneiodonium (DPI) salt synthesis is reported which offers a sustainable and solvent‐free alternative. The solid‐state reactivities of the reported DPI salts were also assessed with the help of morphology predictions and Hirshfeld surface analysis computations to understand the effect of crystal morphology,

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...
