The subject of the invention is a new compound of the following chemical formula:
ABZ.sup.1-Dap(O2(Cbz)).sup.2-Dap(O1).sup.3-Dap(O2).sup.4-Arg.sup.5-ANB.sup.6-NH.sub.2 where: ABZ stands for 2-aminobenzoic acid; DAP stands for diaminopropanoic acid (Dap) derivatives, modified by the functionalised residues of mono-ethylene or diethylene glycol (PEG); ANB stands for 5-amino-2-nitrobenzoic acid The subject of the invention is a method for producing the new compound and a pharmaceutical solution for cancer detection, which contains the above-mentioned compound. The subject of the invention is a method for cancer detection through the in vitro analysis of a human urine sample to which a new compound is added and blended with a buffer of pH 7-9. The subject of the invention is also a kit for detecting cancer, in particular bladder cancer, and the use of hydrolysis of the new compound in the position no. 5 by proteasome 20s for cancer detection, in particular bladder cancer.

The invention provides a method of reducing or preventing mitochondrial permeability transitioning. The method comprises administering an effective amount of an aromatic-cationic peptide having at least one net positive charge; a minimum of four amino acids; a maximum of about twenty amino acids; a relationship between the minimum number of net positive charges (p.sub.m) and the total number of amino acid residues (r) wherein 3p.sub.m is the largest number that is less than or equal to r+1; and a relationship between the minimum number of aromatic groups (a) and the total number of net positive charges (p.sub.t) wherein 2 a is the largest number that is less than or equal to p.sub.t+1, except that when a is 1, p.sub.t may also be 1.

Disclosed here are peptides derived from a serpin reactive center loop that have antiinflammatory, anti-atherogenic and anti-sepsis activity. Compositions containing such serpin-derived peptides are therefore useful in the treatment of transplant vascular disease and also for the treatment of hemorrhagic viral infections as well as lethal viral, fungal or bacterial sepsis in patients.

The present technology provides peptides, methods of generating the peptides, and pharmaceutically acceptable salts of the peptides. In some embodiments, the peptide is D-Arg-26-Dmt-Lys-Phe-NH.sub.2.

Provided herein are antibacterial compounds, wherein the compounds in some embodiments have broad spectrum bioactivity. In various embodiments, the compounds act by inhibition of bacterial type 1 signal peptidase (SpsB), an essential protein in bacteria. Pharmaceutical compositions and methods for treatment using the compounds described herein are also provided.

The disclosure relates to a method for protecting a kidney from renal injury. For example, acute renal injury may be associated with decreased or blocked blood flow in the subject's kidney or exposure to a nephrotoxic agent, such as a radiocontrast dye. The methods include administering to the subject an effective amount of an aromatic-cationic peptide to a subject in need thereof.

The disclosure provides methods of preventing or treating Friedreich's ataxia in a mammalian subject, reducing risk factors, signs and/or symptoms associated with Friedreich's ataxia, and/or reducing the likelihood or severity of Friedreich's ataxia. The methods comprise administering to the subject an effective amount of an aromatic-cationic peptide to e.g., reduce oxidative stress, increase mitochondrial metabolism, or a combination thereof.

Provided herein are compounds of Formula (I) and pharmaceutical compositions thereof, which may be useful as MALT1 inhibitors. Also provided are for the treatment of proliferative disorders (e.g., cancer (e.g., non-Hodgkin's lymphoma, diffuse large B-cell lymphoma, MALT, lymphoma), benign neoplasm, a disease associated with angiogenesis, an autoimmune disease, an inflammatory disease, an autoinflammatory disease) by administering a compound of Formula (I).
