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.

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. 1 Kgp is a cysteine protease virulence factor secreted by Porphyromonas gingivalis, a keystone bacterium in the development of periodontal disease. 2 The secretion of gingipain proteases is part of the asaccharolytic metabolism of P. gingivalis, and the … 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.

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. 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.
The kinetic constants obtained for Rgps were comparable to those of human aminopeptidases but Kgp aminopeptidase activity was weaker. 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. Example 19. Gingipain Inhibitors Prevent Degradation of Human Collagen. P. gingivalis was grown to exponential phase (OD 600 nm=0.6) in a Coy's anaerobic chamber under 5% hydrogen, 10% carbon dioxide, and 95% nitrogen. The bacteria were centrifuged at 5000×g for 10 min at 4° C., and then the supernatant was collected.
