tested potent, selective, brain-penetrant, small-molecule gingipain inhibitors in vivo. Our results indicate that small-molecule inhibi-tion of gingipains has the potential to be disease modifying in AD.

J Periodontol 2003;74:111‐118. Pretreatment of mice with gingipain inhibitors protected their hippocampal neurons from the neurotoxic effects of injecting gingipain directly into the hippocampus. Furthermore, gingipain inhibitors protected the cultured cells from the toxic effects of P. gingivalis , whereas antibiotics, such as moxifloxacin and doxycycline, or semagacestat, a drug that inhibits the production of beta Inhibitors of lysine gingipain Download PDF Info Publication number US9758473B2.

Gingipain inhibitors

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. 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.

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. An arginine gingipain inhibitor may be used as monotherapy in new indications or potentially additively with lysine gingipain inhibitors, like atuzaginstat. 1 INTRODUCTION. COR388 is an irreversible active‐site inhibitor developed to target lysine‐gingipain (Kgp) in the brain of Alzheimer's disease (AD) patients.

Biol … Class-specific inhibitors and gingipain-null mutants showed that gingipains were the only enzymes responsible for this activity. The kinetic constants obtained for Rgps were comparable to those of human aminopeptidases but Kgp aminopeptidase activity was weaker. Gingipain has been studied for its potential role in the development of Alzheimer's Disease. References This page was last edited on 23 September 2019, at 17:44 (UTC).

In mice, small-molecule gingipain inhibitors ameliorate infection, reduce Aβ42 peptide production and neuroinflammation, and protect neurons from gingipain toxicity. 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.

Alternatively, the additional therapeutically active agent can be administered separately before, concurrently with, or after administration of the lysine gingipain inhibitor.

Leupeptin is a bacterial product that inhibits many serine, threonine, and cysteine proteases (Bogyo & Wang, 2002). 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. 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. 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.

At the minimal concentration of 17.826 μM, inhibition up to 98.7% and 89.4% was noted for gingipain R and K respectively. of inhibitors that could be used for the treatment of periodontitis. To develop successful therapeutic gingipain inhibitors, the gingipain chiefly responsible for the virulence of P. gingivalis must be clearly identified. Reynolds et al.
