    The reactions of substituted 3-benzal-2,4-pentanediones, ethyl benzalacetoacetates, diethyl benzalmalonates, benzalmalonamides, cinnamalmalononitriles, β-nitrostyrenes, and β-nitropropenylbenzenes with excess n-butanethiol go essentially to completion in 20% aqueous ethanolic solution buffered to pH 7. The second order rate constants derived from the reactions of meta- and para- substituted derivatives correlate well with Hammett a constants. The nature and conformation of the functional group cis to the phenyl group determines the extent to which ortho substituents hinder the reaction.

  • Novel Multipotent Tacrine−Dihydropyridine Hybrids with Improved Acetylcholinesterase Inhibitory and Neuroprotective Activities as Potential Drugs for the Treatment of Alzheimer's Disease

    日期:2006.12.1
    In this work we describe the synthesis and biological evaluation of the tacrine-1,4-dihydropyridine (DHP) hybrids (3-11). These multipotent molecules are the result of the juxtaposition of an acetylcholinesterase inhibitor (AChEI) such as tacrine (1) and a 1,4-DHP such as nimodipine (2). Compounds 3-11 are very selective and potent AChEIs and show an excellent neuprotective profile and a moderate Ca2+ channel blockade effect. Consequently, these molecules are new potential drugs for the treatment of Alzheimer's disease.
  • Tacripyrines, the First Tacrine−Dihydropyridine Hybrids, as Multitarget-Directed Ligands for the Treatment of Alzheimer’s Disease
    作者:José Marco-Contelles、Rafael León、Cristóbal de los Ríos、Abdelouahid Samadi、Manuela Bartolini、Vincenza Andrisano、Oscar Huertas、Xavier Barril、F. Javier Luque、María I. Rodríguez-Franco、Beatriz López、Manuela G. López、Antonio G. García、María do Carmo Carreiras、Mercedes Villarroya

    Tacripyrines (1-14) have been designed by combining an ACNE inhibitor (tacrine) with a calcium antagonist such as nimodipine and are targeted to develop a multitarget therapeutic strategy to confront AD. Tacripyrines are selective and potent ACNE inhibitors in the nanomolar range. The mixed type inhibition of hAChE activity of compound 11 (IC50 105 +/- 15 nM) is associated to a 30.7 +/- 8.6% inhibition of the proaggregating action of ACNE on the A beta and a moderate inhibition of A beta self-aggregation (34.9 +/- 5.4%). Molecular modeling indicates that binding of compound 11 to the ACNE PAS mainly involves the (R)-11 enantiomer, which also agrees with the noncompetitive inhibition mechanism exhibited by p-methoxytacripyrine 11. Tacripyrines are neuroprotective agents, show moderate Ca2+ channel blocking effect, and cross the blood-brain barrier, emerging as lead candidates for treating AD.
