The present invention provides compounds according to Formula I as described herein, and their use for inhibiting the lysine gingipain protease (Kgp) from the bacterium Porphyromonas gingivalis. Also described are gingipain activity probe compounds and methods for assaying gingipain activity are also described, as well as methods for the treatment of disorders associated with P. gingivalis infection, including brain disorders such as Alzheimer's disease.

The present invention provides compounds according to Formula I as described herein, and their use for inhibiting the lysine gingipain protease (Kgp) from the bacterium Porphyromonas gingivalis. Also described are gingipain activity probe compounds and methods for assaying gingipain activity are also described, as well as methods for the treatment of disorders associated with P. gingivalis infection, including brain disorders such as Alzheimer's disease.

In an embodiment of the invention, a composition for treating a cell population comprises an Affinity Medicant Conjugate (AMC). The medicant moiety can be a toxin including an acylfulvene or a drug moiety. The affinity moiety can be an antibody, a binding protein, a steroid, a lipid, a growth factor, a protein, a peptide or non peptidic. The affinity moiety can be covalently bound to the medicant via a linker. Novel linkers that can be directed to cysteine, arginine or lysine residues based on solution pH allow greater flexibility in preserving and/or generating specific epitopes in the AMC.

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 Alzheimer's disease. In certain embodiments, the invention provides compounds according to Formula I, as described herein, and pharmaceutically acceptable salts thereof. ##STR00001##

The present invention concerns compounds of general formula (I): ##STR00001##
in which Y and Z are chosen from CH and N; T is chosen from CO or SO.sub.2; n is 1 to 3; R1 represents a group chosen, for example, from C1-C3 alkyl chains unsubstituted or substituted by fluorine, the unsubstituted or substituted cyclic, cyano, azido, alkoxy and phenyl groups; and R is chosen from the azido, cyano, alkinyl and 2-benzothiazolyl groups and an optionally substituted aromatic heterocycle with five vertices; and the use thereof in the treatment of bacterial and mycobacterial infections such as, for example, tuberculosis, leprosy and atypical mycobacterial infections. The present invention also concerns pharmaceutical compositions comprising, as the active ingredient, at least one of the abovementioned compounds and optionally an antibiotic activatable via the EthA pathway.
