Synthesis and Multitarget Biological Profiling of a Novel Family of Rhein Derivatives As Disease-Modifying Anti-Alzheimer Agents
We
have synthesized a family of rheinâhuprine hybrids to hit several
key targets for Alzheimerâs disease. Biological screening performed
in vitro and in Escherichia coli cells
has shown that these hybrids exhibit potent inhibitory activities
against human acetylcholinesterase, butyrylcholinesterase, and BACE-1,
dual Aβ42 and tau antiaggregating activity, and brain permeability.
Ex vivo studies with the leads (+)- and (â)-<b>7e</b> in brain slices of C57bl6 mice have revealed that they efficiently
protect against the Aβ-induced synaptic dysfunction, preventing
the loss of synaptic proteins and/or have a positive effect on the
induction of long-term potentiation. In vivo studies in APP-PS1 transgenic
mice treated ip for 4 weeks with (+)- and (â)-<b>7e</b> have shown a central soluble Aβ lowering effect, accompanied
by an increase in the levels of mature amyloid precursor protein (APP).
Thus, (+)- and (â)-<b>7e</b> emerge as very promising
disease-modifying anti-Alzheimer drug candidates
HuprineâTacrine Heterodimers as Anti-Amyloidogenic Compounds of Potential Interest against Alzheimerâs and Prion Diseases
A family of huprineâtacrine heterodimers has been
developed
to simultaneously block the active and peripheral sites of acetylcholinesterase
(AChE). Their dual site binding for AChE, supported by kinetic and
molecular modeling studies, results in a highly potent inhibition
of the catalytic activity of human AChE and, more importantly, in
the in vitro neutralization of the pathological chaperoning effect
of AChE toward the aggregation of both the β-amyloid peptide
(Aβ) and a prion peptide with a key role in the aggregation
of the prion protein. Huprineâtacrine heterodimers take on
added value in that they display a potent in vitro inhibitory activity
toward human butyrylcholinesterase, self-induced Aβ aggregation,
and β-secretase. Finally, they are able to cross the bloodâbrain
barrier, as predicted in an artificial membrane model assay and demonstrated
in ex vivo experiments with OF1 mice, reaching their multiple biological
targets in the central nervous system. Overall, these compounds are
promising lead compounds for the treatment of Alzheimerâs and
prion diseases
Neither mycorrhizal inoculation nor atmospheric CO<sub>2</sub> concentration has strong effects on pea root production and root loss
Chagasâ
disease, caused by the protozoan parasite Trypanosoma
cruzi, is the most common cause of cardiac-related
deaths in endemic regions of Latin America. There is an urgent need
for new safer treatments because current standard therapeutic options,
benznidazole and nifurtimox, have significant side effects and are
only effective in the acute phase of the infection with limited efficacy
in the chronic phase. Phenotypic high content screening against the
intracellular parasite in infected VERO cells was used to identify
a novel hit series of 5-amino-1,2,3-triazole-4-carboxamides (ATC).
Optimization of the ATC series gave improvements in potency, aqueous
solubility, and metabolic stability, which combined to give significant
improvements in oral exposure. Mitigation of a potential Ames and hERG liability ultimately led to two promising compounds, one of which demonstrated significant suppression of parasite burden in a mouse model of Chagasâ disease
