New N,N'-bis(5-arylidene-4-oxo-4,5-dihydrothiazoline-2-yl)diamine derivatives 5 were prepared in two steps from rhodanine and piperazine, or 1,4-bis(3-amino-propyl)piperazine, under microwave reaction conditions with retention of configuration. Some of these compounds were tested for in vitro antiproliferative activities and for their kinase inhibitory(More)
A practical approach for the preparation of ( $$5Z$$ 5 Z ) 5-ylidene rhodanine derivatives bearing the (4,5-dihalogeno-pyrrol-2-yl)carbamoyl fragment of dispacamide A is reported. The new compounds were obtained in good yields (19–88 %) by Knoevenagel condensation according to a solution-phase microwave dielectric heating protocol in the presence of organic(More)
A new route to 3-(4-arylmethylamino)butyl-5-arylidene-2-thioxo-1,3-thiazolidine-4-one 9 was developed in six steps from commercial 1,4-diaminobutane 1 as starting material. The key step of this multi-step synthesis involved a solution phase "one-pot two-steps" approach assisted by microwave dielectric from N-(arylmethyl)butane-1,4-diamine hydrochloride 6a-f(More)
The "Journées Franco-Belges de Pharmacochimie" is a recognized annual meeting in organic and medicinal chemistry known for the quality of scientific exchange and conviviality. Young researchers were encouraged to present their work and share ideas with senior scientists. Abstracts of plenary lectures, oral communications, and posters presented during the(More)
The synthesis of a series of new 3-(3-aminopropyl)-5-arylidene-2-thioxo-1,3-thiazolidine-4-ones hydrochlorides was reported. The key step of this synthetic approach involved a “one-pot two-step” protocol under microwave dielectric heating with good stereocontrol of the Knoevenagel condensation for all these new 5-arylidene rhodanines. The 18 new compounds(More)
We here disclosed a new protocol for the condensation of acetophenone derivatives and active methylene compounds with aldehydes in the presence of boric acid under microwave conditions. Implementation of the reaction is simple, healthy and environmentally friendly owing to the use of a non-toxic catalyst coupled to a solvent-free procedure. A large variety(More)
Dual-specificity tyrosine phosphorylation-regulated kinases (DYRKs) and cdc2-like kinases (CLKs) are implicated in the onset and progression of Down syndrome (DS) and Alzheimer's disease (AD). DYRK1A has emerged as a possible link between amyloid-β (Aβ) and Tau, the major pathological proteins in AD. We here assessed the neuroprotective potential of a novel(More)
