the first selective noncovalent inhibitors of the bacterial cysteine protease IdeS Cleavage of IgG(1) and IgG(3) by gingipain K from Porphyromonas gingivalis

Gingipain inhibitors blocked ApoE proteolysis. MS analysis confirmed higher susceptibility of ApoE4 to gingipain cleavage. MS analysis enabled the identification of cleavage sites and the majority of these sites were concentrated near the carboxy‐terminal of the protein.

2019-03-20 · Structural determinants of inhibition of Porphyromonas gingivalis gingipain K by KYT-36, a potent, selective, and bioavailable peptidase inhibitor Abstract. Porphyromonas gingivalis is a member of the dysbiotic oral microbiome and a “keystone pathogen” that causes Introduction. The human oral Gingipains are potent virulence factors of P. gingivalis, and are likely to be associated with the development of periodontitis. It is, therefore, suggested that gingipain inhibition by vaccination and gingipain-specific inhibitors is a useful therapy for adult periodontitis caused by P. gingivalis infection. These results indicate that gingipains are major virulence factors of P. gingivalis responsible for preterm birth/low birth, and gingipain inhibitors may be useful not only as a therapeutic agent for periodontal diseases, but also as a preventive medicine for preterm birth/low birth weight.

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. Specifically, the gingipain inhibitor reduced deposits of lipids in the aortas of infected animals and prevented the progression of atherosclerosis linked to P. gingivalis infection.

As a member of the wwPDB, the RCSB PDB curates and annotates PDB data according to agreed upon standards. The RCSB PDB also provides a variety of tools and resources. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. These molecules are visualized, downloaded, and analyzed by users who range from students to specialized scientists.

Reynolds et al. initially implicated Kgp, and then RgpB, as the primary virulence factor of P. gingivalis in a murine model of At the minimal concentration of 17.826 μM, inhibition up to 98.7% and 89.4% was noted for gingipain R and K respectively. The data was also supported by the in silico docking experiments which revealed high exothermic enthalpies (−7.01 and −7.02 cal mol −1 ). 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 end-points in periodontal disease. Gingipains are produced by two species of bacteria, Porphyromonas gingivalis and Porphyromonas gulae,typicallyassociatedwithperi- In a 28‐day dose‐response study, COR388 inhibited the lysine‐gingipain target and reduced P. gulae load in saliva, buccal cells, and gingival crevicular fluid.

The company has completed Phase 1 clinical trials of their gingipain inhibitor COR388 , and will run a Phase 2/3 study to determine if it can improve cognition in people with mild to moderate AD, Lynch told Alzforum. Furthermore, KYT-36, in conjunction with KYT-1, a specific inhibitor of arg-specific gingipains, abolished P. gingivalis co-aggregation, hemagglutinating activity, proteolytic activity on various host proteins and the bacterium’s ability to disrupt neutrophil bactericidal activity and fibroblast adherence. Limonianin, inhibited biofilm growth and gingipain activity of P. gingivalis [21].

Specifically, the gingipain inhibitor reduced deposits of lipids in the aortas of infected animals and prevented the progression of atherosclerosis linked to P. gingivalis infection. 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 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. Apart from its potent antimicrobial as well as antibiofilm properties, it also significantly inhibited the gingipains in a dose-dependent manner.

inhibitors. Adding the inhibitors to CDM containing albumin revealed that leupeptin (Arg-gingipain A and B inhibitor) was more efﬁcient at inhibiting growth than cathepsin B inhibitor II (Lys-gingipain inhibitor). Our study suggests that Arg-gingipains and, to a lesser extent, Lys-gingipain play an important role in the growth

These include gingipain N-terminal prodomains, synthetic compounds, inhibitors from natural sources, antibiotics, antiseptics, Gingipains are potent virulence factors of P. gingivalis, and are likely to be associated with the development of periodontitis. It is, therefore, suggested that gingipain inhibition by vaccination and gingipain-specific inhibitors is a useful therapy for adult periodontitis caused by P. gingivalis infection.
