The team has identified three small molecule gingipain inhibitors. The first two, COR286 and COR271 are irreversible inhibitors and have IC 50 values less than 50 pM. And a third molecule COR119 is a reversible inhibitor with an IC 50 of 10 nM. COR388 is a small-molecule inhibitor of gingipains, which are proteins that are released by bacteria species (p.gingivalis) that commonly reside in the mouth. Previous studies have shown that people with bacterial gum disease have a higher risk of developing Alzheimer’s disease ( AD ), and that people with AD have elevated levels of gingipain in their brains, associated with infiltratingp Porphyromonas gingivalis and its proteolytic virulence factors lysine‐gingipain (Kgp) and arginine‐gingipain (Rgp) are emerging as major etiologic agents in the pathogenesis of Alzheimer’s disease (AD).

[33], showed the evidence of presence of gingipains in the brain of Alzheimer's patients31. In animal models, 18 Sep 2017 To determine whether or not gingipains can promote microglia migration in into the somatosensory cortex of mice with or without gingipain inhibitors. Different brain regions are infected with fungi in Alzheimer' 25 Mar 2019 Researchers found gingipains in 96 percent of the brain tissue samples they They found the drug was effective in inhibiting the growth of P. 8 Mar 2019 Examining whether Alzheimer's could have an infectious trigger, the report Moreover, they also identified gingipains, a unique toxin produced by this with small-molecule inhibitors Science Advances 23 Jan 2019: 22 Feb 2019 In the study, “Porphyromonas Gingivalis in Alzheimer's Disease Brains: Disease Causation and Treatment With Small-Molecule Inhibitors,” published correlated the gingipain levels with pathology related to tau, a 2 apr. 2563 BE — P. gingivalis produces toxic virulence factors known as gingipains, and The GAIN (GingipAIN Inhibitor for Treatment of Alzheimer's Disease) 4 dec.

Previous studies have shown that people with bacterial gum disease have a higher risk of developing Alzheimer’s disease ( AD ), and that people with AD have elevated levels of gingipain in their brains, associated with infiltratingp Porphyromonas gingivalis and its proteolytic virulence factors lysine‐gingipain (Kgp) and arginine‐gingipain (Rgp) are emerging as major etiologic agents in the pathogenesis of Alzheimer’s disease (AD). We have previously reported that gingipains colocalize with neuronal cell bodies in over 90% of AD brains studied and the presence of gingipains strongly correlates with tau pathology. We A lysine gingipain inhibitor of the invention can be administered in the same composition as an additional therapeutically active agent. Alternatively, the additional therapeutically active agent can be administered separately before, concurrently with, or after administration of the lysine gingipain inhibitor.

In mice, small-molecule gingipain inhibitors ameliorate infection, reduce Aβ42 peptide production and neuroinflammation, and protect neurons from gingipain toxicity. Porphyromonas gingivalis, the keystone pathogen in chronic periodontitis, was identified in the brain of Alzheimer’s disease patients. Toxic proteases from the bacterium called gingipains were also Oral administration of gingipain inhibitors to mice with established brain infections decreases the abundance of P. gingivalis DNA in brain and mitigates the neurotoxic effects of P. gingivalis infection.

In certain embodiments, the invention provides compounds according to Formula (I), as described herein 2021-2-7 · The presentation, abstract OC28, is entitled, “COR388, A Novel Gingipain Inhibitor, Decreases Fragmentation of ApoE in Alzheimer’s Disease Central Nervous System,” and will take place on Saturday, December 7, at 10:00 a.m. local time.

Gingipain inhibition reduced the bacterial load of an established P. gingivalis brain infection, blocked Aβ 1-42 production, reduced neuroinflammation, and rescued neurons in the hippocampus. These data suggest that gingipain inhibitors could be valuable for treating P. gingivalis brain colonization and neurodegeneration in Alzheimer's disease.

The double-blind, randomized, placebo-controlled trial has been fully enrolled at 643 participants with AD. The GAIN Clinical Trial The GAIN Trial (GingiPAIN inhibitor for treatment of Alzheimer’s disease) is a pivotal Phase 2/3 randomized, double-blind, placebo-controlled study that is assessing the efficacy, safety, and tolerability of two dose levels of COR388 oral capsules in subjects with mild to moderate Alzheimer’s disease. 2021-02-15 · The GAIN (GingipAIN Inhibitor for Treatment of Alzheimer’s Disease) Trial is a randomized, double-blind, placebo-controlled Phase 2/3 trial evaluating the efficacy, safety, and tolerability of Oral administration of gingipain inhibitors to mice with established brain infections decreases the abundance of P. gingivalis DNA in brain and mitigates the neurotoxic effects of P. gingivalis infection.

Background: Porphyromonas gingivalis (P. gingivalis) and its gingipain virulence factors have been identified as pathogenic effectors in Alzheimer’s disease (AD).In a recent study we demonstrated the presence of gingipains in over 90% of postmortem AD brains, with gingipains localizing to the cytoplasm of neurons.
