The role of copper in disulfiram-induced toxicity and radiosensitisation of cancer cells. [PDF]

, 2013
Disulfiram has been used for several decades in the treatment of alcoholism. It now shows promise as an anti-cancer drug and radiosensitizer. Proposed mechanisms of action include the induction of oxidative stress and inhibition of proteasome activity ...

Synthesis of Novel C‐Acyl‐Glycosyl Sulfonamides via Pd‐Catalyzed Carbonylative Coupling

European Journal of Organic Chemistry, EarlyView.
A Pd‐catalyzed carbonylative coupling of 1‐iodo‐glycals with diverse sulfonamides using Mo(CO)6 enables efficient access to C‐acyl‐glycosyl sulfonamides.This robust and versatile strategy delivers novel glycoside derivatives in good to excellent yields, highlighting their potential for drug discovery.

Redox Properties of Catalytically Generated Iminium Ions From α,β‐Unsaturated Aldehydes and Chiral Secondary Amines

European Journal of Organic Chemistry, EarlyView.
We present a rapid, operationally simple, and broadly applicable protocol for the catalytic formation and in situ electrochemical characterization of chiral a,b‐unsaturated iminium ions by cyclic voltammetry (CV). Using only 5 mol% of the aminocatalyst, we systematically measure the reduction potential of over 50 iminium intermediates, revealing how ...

Synthesis of Oxazolyl‐Piperidines Bearing a Quaternary Stereocenter Through a Multicomponent Reaction Involving α‐Isocyanoacetates and Piperidones

European Journal of Organic Chemistry, EarlyView.
Straightforward access to oxazole‐containing piperidines through a multicomponent reaction from α‐isocyanoacetates is described. By expanding the reactivity of these a‐isocyanoacetates from aldehydes to ketones, this process efficiently delivers oxazolyl‐piperidines bearing a quaternary stereocenter as valuable scaffolds relevant to drug discovery. The

Vinylogous aldol reaction of heterocyclic silyloxy dienes. Application in synthesis [PDF]

, 2000
A versatile, readily accessible triad of 2-enoxy silane synthons derived from furan, pyrrole, and thiophene is presented. These heterocycles, in reacting with carbonyl and carbonyl- related acceptors, act as vinylogous nucleophile modules, giving rise ...

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

Taurine-Based Hybrid Drugs as Potential Anticancer Therapeutic Agents: In Vitro, In Vivo Evaluations

Pharmaceuticals
Background/Objectives: The development of antitumor agents possessing low toxicity against non-cancerous cells is still a challenge in medicinal chemistry. In this paper, we report the antitumor activity of “hybrid structures” derived from the amino acid

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Preclinical Evaluation of Berry Extracts as a Nutritional Intervention to Alleviate Myocardial Ischemia–Reperfusion Injury and Atherosclerosis Development

Phytotherapy Research, EarlyView.
Schematic representation of the experimental design and the proposed mechanisms underlying the cardioprotective and anti‐atherosclerotic effects of Greek‐derived berry extracts. C57BL/6 mice with WD–induced MS and ApoE−/− mice with atherosclerosis received chronic supplementation with WMex or BBex.
