The Cracked Potential of Boron-containing Compounds in Alzheimer's Disease.

Alzheimer's disease (AD) is a relevant neurodegenerative disease worldwide. Its relevancy is mainly due to its high prevalence and high global burden. Metalloids have attracted attention as their serum levels seem to differ between affected patients and healthy individuals.

Pharmacokinetics and tissue distribution of N-(2-hydroxyphenyl)-2-propylpentanamide in Wistar Rats and its binding properties to human serum albumin.

N-(2-hydroxyphenyl)-2-propylpentanamide (HO-AAVPA) is a novel valproic acid derivative that has shown anti-proliferative activity against epitheloid cervix carcinoma (HeLa), rhabdomyosarcoma (A204), and several breast cancer cell lines. The aim of this research was to evaluate the pharmacokinetic profile and tissue distribution of HO-AAVPA in Wistar rats, as well as its human serum albumin binding potential by experimental and in silico methods. A single dose of HO-AAVPA was given to male rats by intravenous, intragastric or intraperitoneal routes at doses of 25, 100, and 100 mg/kg, respectively.

Scope of Lipid Nanoparticles in Neuroscience: Impact on the Treatment of Neurodegenerative Diseases.

Background: Lipid nanoparticles have been studied mainly as a means of transporting and releasing drugs. A special emphasis has been placed on designing nanoparticles that improve the delivery of drugs with targets in the central nervous system.

Methods: The biomedical literature was searched for basic and clinical studies.

Insights into the structural biology of G-protein coupled receptors impacts drug design for central nervous system neurodegenerative processes.

In the last few years, there have been important new insights into the structural biology of G-protein coupled receptors. It is now known that allosteric binding sites are involved in the affinity and selectivity of ligands for G-protein coupled receptors, and that signaling by these receptors involves both G-protein dependent and independent pathways. The present review outlines the physiological and pharmacological implications of this perspective for the design of new drugs to treat disorders of the central nervous system.

In vitro and molecular modeling analysis of two mutant desert hedgehog proteins associated with 46,XY gonadal dysgenesis.

Mutations of Desert hedgehog (DHH) have been associated to 46,XY pure gonadal dysgenesis (PGD) and to mixed gonadal dysgenesis (MGD); however, there have been no functional studies of mutations described in DHH. To determine if mutations p.L162P and Δ1086delG yield functional impairment, we performed in vitro and in silico analysis of both DHH mutants.

Clinical implications of recent insights into the structural biology of beta2 adrenoceptors.

Analysis of the crystal structure of beta-2 adrenoceptors (β2ARs) is providing new insights into the functioning of this receptor and perhaps of G-protein coupled receptors (GPCRs) as a whole. This class of receptors represents the target of at least a third of the drugs on the market and plays an essential role in the study of therapetic drug-response. Among GPCRs, the β2AR is the best understood in terms of function, expression and activation.

Pharmacokinetic parameters and a theoretical study about metabolism of BR-AEA (a salbutamol derivative) in rabbit.

In this study, we report the pharmacokinetics of 1-(4-di-hydroxy-3,5-dioxa-4-borabicyclo[4.4.0]deca-7,9,11- trien-9-yl)-2-(tert-butylamino)ethanol (BR-AEA).
