1 INTRODUCTION. COR388 is an irreversible active‐site inhibitor developed to target lysine‐gingipain (Kgp) in the brain of Alzheimer's disease (AD) patients. 1 Kgp is a cysteine protease virulence factor secreted by Porphyromonas gingivalis, a keystone bacterium in the development of periodontal disease. 2 The secretion of gingipain proteases is part of the asaccharolytic metabolism of P

In mice, small-molecule gingipain inhibitors ameliorate infection, reduce Aβ42 peptide production and neuroinflammation, and protect neurons from gingipain toxicity. 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 The third Cortexyme presentation, titled “COR388 (atuzaginstat), a novel gingipain inhibitor, decreases ApoE fragmentation in the CNS of Alzheimer’s disease patients” (Abstract 40578P3), presents data indicating P. gingivalis gingipains target and cleave ApoE proteins in the nervous system of AD patients. In a poster titled “Comprehensive Alzheimer’s pathology is induced by Porphyromonas gingivalis infection: atuzaginstat (COR388) and other proprietary gingipain inhibitors protect against synaptic These data suggest that gingipain inhibitors could be valuable for treating P. gingivalis brain colonization and neurodegeneration in Alzheimer’s disease.

TWiM 195: Gingipain in the Alzheimer brain March 4, 2019 Michael and Vincent discuss the finding of immunity to Cas9 protein in humans, and a potential role for an oral bacterium in Alzheimer’s disease. The level of gingipain inhibition can range from about 5% to about 95%, or from about 10% to about 90%, or from about 20% to about 80%, or from about 30% to about 70%, or from about 40% to about 60%. In some embodiments, contacting the gingipain with a compound as described herein will result in complete (i.e., 100%) gingipain inhibition. The team has identified three small molecule gingipain inhibitors.

Periodontal disease (PD) and Alzheimer's disease (AD) are inflammatory [35] demonstrated that the gingipain protease complex from P. gingivalis W50 has an “Binding of complement inhibitor C4b-binding protein contributes to ser 7 Dec 2020 COR388, a novel gingipain inhibitor, decreases fragmentation of APOE in the central nervous system of Alzheimer's disease patients · Related 7 May 2020 “We believe gingipain inhibition has the potential to be an important, differentiated mechanism of action against AD, and are committed to fully Oral Health and Alzheimers Disease Part 1: Oral Infection and Alzheimer's in mice, these novel small molecular weight gingipain inhibitors offer promise for 8 Aug 2019 Cortexyne Inc is developing a therapy that uses the COR388 gingipain inhibitor to target P gingivalis and combat Alzheimer's disease.

The investigators, including Stephen Dominy, MD, the chief scientific officer of Cortexyme, which has developed a gingipain inhibitor, CORE-388, identified the pathogen in the brains of patients with Alzheimer disease, as well as the organism’s gingipains—lysine-gingipain (Kgp), arginine-gingipain A (RgpA), and arginine-gingipain B (RgpB)—in the neurons of these patients.

These data suggest that gin-gipain inhibitors could be valuable for treating P. gingivalis brain colonization and neurodegeneration in Alzheimer’s disease. However, periodontal disease is a major co-morbidity in Alzheimer’s disease and gingipain inhibitors acting to reduce microglial activation and the expression of pro-inflammatory mediators may well have a significant impact on disease progression.

The GAIN (GingipAIN Inhibitor for Treatment of Alzheimer’s Disease) Trial is based on a growing body of scientific evidence that the bacteria P. gingivalis, most commonly associated with degenerative gum disease, can infect the brain and cause Alzheimer’s disease.

Gingipains are produced by two species of bacteria, Porphyromonas gingivalis and Porphyromonas gulae , typically associated with periodontal disease and systemic infections in humans and dogs COR388, a novel gingipain inhibitor, decreases fragmentation of ApoE in Alzheimer’s disease central nervous system.

Abstract: Many efforts have been made to develop therapeutic agents for Alzheimer’s Disease (AD) based on the amyloid cascade hypothesis, but there is no effective therapeutic agent at present. 2019-5-2 2021-2-9 2021-4-9 · The path to tackling Alzheimer's disease is littered with failures, but when a company generates even early hints of promise the rewards are high. Take tiny Inmune Bio, whose shares rocketed 78% this week on phase Ib data with XPro1595, a TNF inhibitor said to decrease neuroinflammation. The present invention relates generally to therapeutics targeting the bacterium Porphyromonas gingivalis , including its protease Lysine gingipain (Kgp), and their use for the treatment of disorders associated with P. gingivalis infection, including brain disorders such as Alzheimers disease.

It turns out the gingipains are cleaving – chopping up – the tau proteins into fragments. Some of the fragments found after the gingipains cleaved tau match some fragments known to be found in the cerebrospinal fluid of Alzheimer’s patients.
