Proteome Aggregation in Cells Derived from Amyotrophic Lateral Sclerosis Patients for Personalized Drug Evaluation.

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder that currently lacks effective therapy. Given the heterogeneity of clinical and molecular profiles of ALS patients, personalized diagnostics and pathological characterization represent a powerful strategy to optimize patient stratification, thereby enabling personalized treatment. Immortalized lymphocytes from sporadic and genetic ALS patients recapitulate some pathological hallmarks of the disease, facilitating the fundamental task of drug screening.

Stepwise Structural Simplification of the Dihydroxyanthraquinone Moiety of a Multitarget Rhein-Based Anti-Alzheimer Lead to Improve Drug Metabolism and Pharmacokinetic Properties.

Multitarget compounds have emerged as promising drug candidates to cope with complex multifactorial diseases, like Alzheimer's disease (AD). Most multitarget compounds are designed by linking two pharmacophores through a tether chain (linked hybrids), which results in rather large molecules that are particularly useful to hit targets with large binding cavities, but at the expense of suffering from suboptimal physicochemical/pharmacokinetic properties. Molecular size reduction by removal of superfluous structural elements while retaining the key pharmacophoric motifs may represent a compromise solution to achieve both multitargeting and favorable physicochemical/PK properties.

Effect of the aggregated protein dye YAT2150 on parasite viability.

The problems associated with the drugs currently used to treat leishmaniasis, including resistance, toxicity, and the high cost of some formulations, call for the urgent identification of new therapeutic agents with novel modes of action. The aggregated protein dye YAT2150 has been found to be a potent antileishmanial compound, with a half-maximal inhibitory concentration (IC) of approximately 0.5 µM against promastigote and amastigote stages of .

Acetylcholinesterase: A Versatile Template to Coin Potent Modulators of Multiple Therapeutic Targets.

ConspectusThe enzyme acetylcholinesterase (AChE) hydrolyzes the neurotransmitter acetylcholine (ACh) at cholinergic synapses of the peripheral and central nervous system. Thus, it is a prime therapeutic target for diseases that occur with a cholinergic deficit, prominently Alzheimer's disease (AD). Working at a rate near the diffusion limit, it is considered one of nature's most efficient enzymes.
