Disclosed are various crystalline salt forms of D-Arg-Dmt-Lys-Phe-NH.sub.2.

The present invention relates to a compound of formula (I) AA-AA-AA-R.sub.1—R.sub.2 (I) wherein, in any order, 2 of said AA (amino acid) moieties are cationic amino acids and 1 of said AA is an amino acid with a lipophilic R group, the R group having 14-27 non-hydrogen atoms; R.sub.1 is a N atom, which may be substituted by a branched or unbranched C.sub.1-C.sub.10 alkyl or aryl group, which group may incorporate up to 2 heteroatoms selected from N, O and S; and R.sub.2 is an aliphatic moiety having 2-20 non-hydrogen atoms, said moiety being linear, branched or cyclic. The invention further relates to formulations containing these compounds, solid supports having these compounds attached thereto, the use of these compounds in therapy, particularly as antimicrobial, anti-tumour or anti-biofilm agents and non-therapeutic uses of these compounds, particularly their use in inhibiting biofilm formation or removing a biofilm.

The disclosure provides methods of preventing or treating heart failure in a mammalian subject. The methods comprise administering to the subject an effective amount of an aromatic-cationic peptide to subjects in need thereof.

The present disclosure provides c-Met antibody drug conjugates (ADCs), including compositions and methods of using such ADCs.

A heterobifunctional monodisperse polyethylene glycol with two adjacent monodisperse polyethylene glycol side chains, in which a peptide linker is degraded by intracellular enzymes to release a drug slowly and effectively mask the hydrophobicity of the drug, and an antibody-drug conjugate in which the antibody and the drug are bound using same is provided. A heterobifunctional monodisperse polyethylene glycol represented by the formula (1):

##STR00001##

wherein each symbol in the formula (1) is as defined in the DESCRIPTION.

The disclosure generally describes methods of preventing or treating ophthalmic diseases or conditions in a mammalian subject, such as diabetic retinopathy, cataracts, retinitis pigmentosa, glaucoma, macular degeneration, choroidal neovascularization, retinal degeneration, and oxygen-induced retinopathy. The methods comprise administering an effective amount of an aromatic-cationic peptide to subjects in need thereof.

The present disclosure provides c-Met antibody drug conjugates (ADCs), including compositions and methods of using such ADCs.

Disclosed are non-natural peptides useful for the treatment and prevention of ischemia-reperfusion injury (e.g., cardiac ischemia-reperfusion injury) or myocardial infarction.

The present invention relates to a peptide with amidated carboxy terminus having melanogenesis inhibitory activity and a composition comprising same, and more specifically, to a peptide with amidated (—NH.sub.2) carboxy terminus, composed of one amino acid sequence selected from the group consisting of SEQ ID NO: 3, SEQ ID NO: 5, SEQ ID NO: 9 to 18, and a pharmaceutical composition, cosmetic composition, and food composition for the treatment of pigmentation diseases comprising same as an active ingredient.

Compounds comprising R-G-Cysteic Acid (i.e., R-G-NH—CH(CH.sub.2—SO.sub.3H)COOH or Arg-Gly-NH—CH(CH.sub.2—SO.sub.3H)COOH) and derivatives thereof, including pharmaceutically acceptable salts, hydrates, stereoisomers, multimers, cyclic forms, linear forms, drug-conjugates, pro-drugs and their derivatives. Also disclosed are methods for making and using such compounds including methods for inhibiting integrins including but not necessarily limited to α.sub.5β.sub.1-Integrin, α.sub.vβ.sub.3-Integrin and α.sub.vβ.sub.5-Integrin, inhibiting cellular adhesion to RGD binding sites, preventing or treating viral or other microbial infections, inhibiting angiogenesis in tumors, retinal tissue or other tissues or delivering other diagnostic or therapeutic agents to RGD binding sites in human or animal subjects.
