Amyloid proteotoxicity initiates an inflammatory response blocked by cannabinoids. [PDF]

open access: yes, 2016
The beta amyloid (Aβ) and other aggregating proteins in the brain increase with age and are frequently found within neurons. The mechanistic relationship between intracellular amyloid, aging and neurodegeneration is not, however, well understood.

alpha- and beta-secretase: profound changes in Alzheimer's disease.

open access: yesBiochemical and biophysical research communications, 2003
The amyloid plaque, a neuropathological hallmark of Alzheimer's disease, is produced by the deposition of beta-amyloid (Abeta) peptide, which is cleaved from Amyloid Precursor Protein (APP) by the enzyme beta-secretase. Only small amounts of Abeta form in normal brain; more typically this is precluded by the processing of APP by alpha-secretase.

Influence of conformational fluctuations on enzymatic activity: modelling the functional motion of beta-secretase

open access: yes, 2005
Considerable insight into the functional activity of proteins and enzymes can be obtained by studying the low-energy conformational distortions that the biopolymer can sustain. We carry out the characterization of these large scale structural changes for

SIRT3 activator Honokiol attenuates β-Amyloid by modulating amyloidogenic pathway.

open access: yesPLoS ONE, 2018
Honokiol (poly-phenolic lignan from Magnolia grandiflora) is a Sirtuin-3 (SIRT3) activator which exhibit antioxidant activity and augment mitochondrial functions in several experimental models.

Aminomethyl-Derived Beta Secretase (BACE1) Inhibitors: Engaging Gly230 without an Anilide Functionality

open access: yesJournal of Medicinal Chemistry, 2016
A growing subset of β-secretase (BACE1) inhibitors for the treatment of Alzheimer's disease (AD) utilizes an anilide chemotype that engages a key residue (Gly230) in the BACE1 binding site. Although the anilide moiety affords excellent potency, it simultaneously introduces a third hydrogen bond donor that limits brain availability and provides a ...

Decrease in the production of beta-amyloid by berberine inhibition of the expression of beta-secretase in HEK293 cells

open access: yesBMC Neuroscience, 2011
Background Berberine (BER), the major alkaloidal component of Rhizoma coptidis, has multiple pharmacological effects including inhibition of acetylcholinesterase, reduction of cholesterol and glucose levels, anti-inflammatory, neuroprotective and ...
