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 present invention provides compounds of formula (I)

##STR00001## wherein X.sup.1 to X.sup.8 and R.sup.1 to R.sup.8 are as described herein, as well as pharmaceutically acceptable salts thereof. Further the present invention is concerned with the manufacture of the compounds of formula (I), pharmaceutical compositions comprising them and their use as medicaments for the treatment of diseases and infections caused by Acinetobacter baumannii.

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 invention provides compounds of formula (I) ##STR00001## wherein X, L.sup.1 and R.sup.1 to R.sup.10 are as described herein, as well as pharmaceutically acceptable salts thereof. Further the present invention is concerned with the manufacture of the compounds of formula (I), pharmaceutical compositions comprising them and their use as medicaments for the treatment of diseases and infections caused by Acinetobacter baumannii.

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 invention provides a novel class of cyanine dyes that are functionalized with sulfonic acid groups and a linker moiety that facilitates their conjugation to other species and substituent groups which increase the water-solubility, and optimize the optical properties of the dyes. Also provided are conjugates of the dyes, methods of using the dyes and their conjugates and kits including the dyes and their conjugates.

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

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 present disclosure relates to imaging agent formulations, methods for preparing imaging agent formulations and methods for using the same. The present disclosure also relates to kits for imaging agent formulations.
