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. 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. Arginine gingipain is a distinct target associated with P. gingivalis that contributes to bacterial survival, replication and toxicity. An arginine gingipain inhibitor may be used as monotherapy Arginine gingipain is a distinct target associated with P. gingivalis that contributes to bacterial survival, replication and toxicity.

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. 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.

In certain embodiments, the invention provides compounds according to Formula I, as described herein 2001-08-01 Suppression of Pathogenicity of Porphyromonas gingivalis by Newly Developed Gingipain Inhibitors Tomoko Kadowaki, Atsuyo Baba, Naoko Abe, Ryosuke Takii, Munetaka Hashimoto, Therefore, a combination of RTV and Kgp inhibitors can be used to increase plasma concentrations and brain levels of the gingipain inhibitors. As described in U.S. patent application Ser. No. 14/875,416, oral administration of RTV 15 minutes prior to the Kgp inhibitor Kyt-36 increases the half-life therefore it is expected that RTV will also increase the half-life of other Kgp inhibitors. 2003-04-01 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’ Arginine gingipain is a distinct target associated with P. gingivalis that contributes to bacterial survival, replication and toxicity. An arginine gingipain inhibitor may be used as monotherapy in new indications or potentially additively with lysine gingipain inhibitors, like atuzaginstat.

Cleavage of IgG1 and IgG3 by gingipain K from Porphyromonas gingivalis may compromise host defense in progressive periodontitis. This page in English.

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 Total of 'gingipain k inhibitors': 1 product(s) 4025803 Z-Phe-Lys-2,4,6-trimethylbenzoyloxy-methylketone trifluoroacetate salt Z-FK-ck Potential value of a rice protein extract, containing proteinaceous inhibitors against cysteine proteinases from Porphyromonas gingivalis, for managing periodontal diseases.

Thus, the inhibitor appears to surpass other strategies involving protease inhibitors in various biochemical and clinical points of view. Consequently, this dual inhibitor in topical formulations is thought to be a promising agent for preventing and treating gingivitis or early PD.

Gingipains degrade a broad range of proteins (e.g., immunoglobulins, proteinase inhibitors, actin, and collagen) which can lead to cytoskeleton collapse and apoptosis in many types of cells. Recent research has demonstrated that small, peptide-derived inhibitors of Kgp … Arg-gingipain (Rgp) and Lys-gingipain (Kgp) are cysteine proteinases produced by Porphyromonas gingivalis, a major etiological bacterium of periodontal diseases. Here we show a series of small peptide analogs able to inhibit either Rgp or Kgp, which are synthesized on the basis of the cleavage site specificity of human salivary histatins by each enzyme. Therefore, a dual inhibitor of both gingipains would have attractive clinical potential for PD therapy. In this study, a novel, potent, dual inhibitor of Rgp and Kgp was developed through structure‐based drug design, and its biological potency was evaluated in vitro and in vivo. COR388 is an irreversible active‐site inhibitor developed to target lysine‐gingipain (Kgp) in the brain of Alzheimer's disease (AD) patients.

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

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.

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. Gingipain inhibition reduced the bacterial load of an established P. gingivalis brain infection, blocked Aβ1–42 production, reduced neuroinflammation, and rescued neurons in the hippocampus.
