This study found that the gingipains related to periodontal disease have a inhibitor in mice that showed some promise in modifying 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.

We identified the bacterial pathogen, Porphyromonas gingivalis(Pg), and its protease virulence factors, gingipains, in the brain of patients with Alzheimer’s disease (AD). Gingipain levels in AD brains were shown to significantly correlate with AD diagnosis and tau and ubiquitin pathology. Gingipains are the major virulence factors of Porphyromonas gingivalis, the main periodontopathogen. It is expected that inhibition of gingipain activity in vivo could prevent or slow down the Remember, gingipains are proteases, meaning they like to chop up proteins.

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. 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 ). 23 Jan 2019 Gingipain inhibition reduced the bacterial load of an established P. gingivalis brain infection, blocked Aβ 1–42 production, reduced with various neuropathological hallmarks of Alzheimer's disease.

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 data suggest that gingipain inhibitors could be valuable for treating P. gingivalis brain colonization and neurodegeneration in Alzheimer's disease. People with Alzheimer’s disease have elevated levels of the bacterial protease gingipain in their brain tissue, they find.
