KYT-36

KYT-36 is a potent, selective, and bioavailable inhibitor of P. gingivalis virulence factor gingipain K (Kgp, lysine-gingipain), potently and selectively inhibits Kgp with Ki of 0.27 nM, respectively.KYT-36 consists of benzyloxycarbonyl (BOC), L-glutaminyl (GLN), methylphenylamino (MPA), L-lysinyl (LYS), and benzylcarbamoyl (BCA) moieties.KYT-36 strongly inhibited degradation of host proteins in culture supernatants and abolished thriving of P. gingivalis in cell cultures and in periodontal pockets in vivo.KYT-36 prevented Kgp-triggered vascular permeability in guinea pigs, i.e. demonstrating its efficacy against bacterial virulence in vivo, with no toxicity effects.
