Methods of treating aging related skin changes and of increasing skin thickness with topical administration of N-acyldipeptide derivatives are described. Compositions comprising N-acyldipeptide derivatives, are therapeutically effective for increasing skin thickness, and for treating extrinsic and intrinsic aging and aging related skin changes, such as fine lines, wrinkles, photoaging, hyperpigmentation, laxity, age spots, lentigines, mottled skin, and cellulite.

Provided is a method of preparing an N-acetyl dipeptide and an N-acetyl amino acid, the method including producing the N-acetyl dipeptide and the N-acetyl amino acid by reaction of an amino acid with acetic anhydride or acetyl chloride.

The present disclosure includes a construct comprising a leupeptin biosynthesis operon, the operon comprising leupA, leupB, leupC, and leupD genes operably linked to a promoter. Also included are cells comprising the construct, and methods for production of leupeptin peptide.

The present invention regards specific IBAT inhibitors useful in the prophylaxis and/or treatment of a liver disease. It also relates to compositions comprising these IBAT inhibitors, a method for treatment of the disorders and a kit comprising the substances or the compositions.

Provided is a pharmaceutical formulation comprising a modified IL-7 protein. More particularly, it comprises (a) a modified IL-7 fusion protein; (b) a basal buffer with a concentration of 10 to 50 mM; (c) a sugar with a concentration of 2.5 to 5 w/v%; and (d) a surfactant with a concentration of 0.05 to 6 w/v%.

Such pharmaceutical formulation of a modified IL-7 fusion protein does not show aggregates formation, but shows protective effects on proteins under stress conditions such as oxidation or agitation, and thus can effectively be used for the treatment of a patient.

Disclosed are compounds that can penetrate the mitochondrial membrane and that are able to deliver cargo (e.g., therapeutic agents) specifically to the mitochondria.
