The bioinspired design of a reagent allows the functionalization of C<sub>α</sub>–H of α,β-unsaturated carbonyl compounds via the Baylis–Hillman chemistry under ambient conditions
A rationally designed reagent capable to affect alkylation at C[small alpha] of [small alpha], [small beta]-unsaturated carbonylcompounds is reported. The reaction proceeded at room temperature without any additives. The pH and H-Bond...

Derivatives of N-[2-(dimethylamino)ethyl]-9-aminoacridine-4-carboxamide bearing a wide variety of different groups at the 5-position (and for comparative purposes at the 7-position) have been prepared, and their physicochemical properties and biological activities have been determined. Although both 5- and 7-substituted compounds bind equally well to DNA by intercalation, only the 5-substituted compounds
A number of tricyclic carboxamides have been synthesized and tested to evaluate their ability to reverse multidrug resistance in the (CHC)-C-R/5 cell line. Among them the acridone derivatives were the most potent, A key feature is the presence of a dimethoxybenzyl or phenethylamine cationic site, separated from the tricyclic lipophilic part by a carbamoylphenyl chain. Optimization led to compounds 2 orders of magnitude more active than the prototype inhibitors verapamil and amiodarone. On the basis of in vitro and in vivo activities, 9,10-dihydro-5-methoxy- 9-oxo-N-[4-[2-(1,2,3,4-tetrahydro-6,7-dimethoxyisoquinol-2-yl)ethyl]phenyl]-4-acridinecarboxamide (84) has been selected for further development.
