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.

Remember, gingipains are proteases, meaning they like to chop up proteins. 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.

People with Alzheimer’s disease have elevated levels of the bacterial protease gingipain in their brain tissue, they find. 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. Thus, gingipain inhibition could provide a potential approach to the treatment of both periodontitis and AD. 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 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. Thus, gingipain inhibition could provide a potential approach to the treatment of both periodontitis and AD. 1 INTRODUCTION This small molecule gingipain inhibitor is atuzaginstat, and it's being studied by CRTX in late stage studies in periodontitis and Alzheimer’s, the latter is, of course, the value driver. Pipeline 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.

Background 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’ 2019-01-25 · The team members from Cortexyme, a biotech in the Bay Area, developed more gingipain inhibitors through a med-chem effort. Looking at some of their patents , these appear to be tetrafluorophenyl esters as covalent inhibitors – two compounds in particular (COR271 and COR286) are the subject of this paper. 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. COR388, a small‐molecule lysine‐gingipain inhibitor, is currently being investigated in a Phase 2/3 clinical trial for Alzheimer's disease (AD) with exploratory endpoints in periodontal disease.

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.

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.

Authors Shinsuke Kataoka 1 COR388, a novel lysine‐gingipain inhibitor, is currently being tested in a Phase 2/3 clinical trial to target Pg for the treatment of AD. Based on the current preclinical data reported here, COR388 has the potential to attenuate atheroma formation and systemic inflammation in Pg‐ induced atherosclerosis and therefore may have beneficial Remember, gingipains are proteases, meaning they like to chop up proteins. 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 … 1 INTRODUCTION.

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). 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.
