Disclosed herein include methods, compositions, and kits suitable for use in preventing, treating or reverse fibrosis. The methods comprise administering to a subject in need thereof a composition comprising a cyclosporine analogue (for example, CRV431), or a pharmaceutically acceptable salt, solvate, stereoisomer thereof. The compositions and kits comprise a cyclosporine analogue (for example, CRV431), or a pharmaceutically acceptable salt, solvate, stereoisomer thereof.

Use of cyclosporine analogues for treating fibrosis

The invention is directed to isomeric mixtures of cyclosporine analogues that are structurally similar to cyclosporine A. The mixtures possess enhanced efficacy and reduced toxicity over the individual isomers and over naturally occurring and other presently known cyclosporines and cyclosporine derivatives. Embodiments of the present invention are directed toward cis and trans-isomers of cyclosporin A analogs referred to as ISA247, and derivatives thereof. Mixtures of ISA247 isomers exhibit a combination of enhanced potency and reduced toxicity over the naturally occurring and presently known cyclosporins. ISA247 isomers and alkylated, arylated, and deuterated derivatives are synthesized by stereoselective pathways where the particular conditions of a reaction determine the degree of stereoselectivity. The ratio of isomers in a mixture may range from about 10 to 90 percent by weight of the (E)-isomer to about 90 to 10 percent by weight of the (Z)-isomer, based on the total weight of the mixture.

Mixtures of ISA247 isomers exhibit a combination of enhanced potency and reduced toxicity over the naturally occurring and presently known cyclosporins. ISA247 isomers and alkylated, arylated, and deuterated derivatives are synthesized by stereoselective pathways where the particular conditions of a reaction determine the degree of stereoselectivity. The ratio of isomers in a mixture comprises from about 70 to about 80 percent by weight of the E-isomer and from about 20 to about 30 percent by weight of the Z-isomer, based on the total weight of the mixture.

ISA247 isomers and alkylated, arylated, and deuterated derivatives are synthesized by stereoselective pathways where the particular conditions of a reaction determine the degree of stereoselectivity. The ratio of isomers in a mixture comprises greater than about 80 percent by weight of the E-isomer and less than about 20 percent by weight of the Z-isomer, based on the total weight of the mixture.

The present invention relates to formulations containing cyclosporin analogs that are structurally similar to cyclosporin A, in particular isomeric mixtures of cyclosporin analogs that are structurally similar to cyclosporin A. The formulations form stable microemulsion preconcentrates and may provide superior drug bioavailability and/or may reduce one or more adverse effects associated with the administration of cyclosporin. Also disclosed are methods for using and preparing the formulations.

Cyclosporin analog formulations

Cyclosporine derivatives are disclosed which possess enhanced efficacy and reduced toxicity over naturally occurring and other presently known cyclosporins and cyclosporine derivatives. The cyclosporine derivatives of the present invention are produced by chemical and isotopic substitution of the cyclosporine A (CsA) molecule by: (1) Chemical substitution and optionally deuterium substitution of amino acid 1; and (2) deuterium substitution at key sites of metabolism of the cyclosporine A molecule such as amino acids 1, 4, 9. Also disclosed are methods of producing the cyclosporine derivatives and method of producing immunosuppression with reduced toxicity with the disclosed cyclosporine derivatives.

Deuterated cyclosporin analogs and their use as immunomodulating agents

This invention provides modified rapamycins that have specific monosaccharide(s), oligosaccharide(s), pseudosugar(s) or derivatives thereof attached through a linker to create rapamycin carbohydrate derivatives having enhanced pharmacokinetic and/or pharmacodynamic profiles. For example, administration of the rapamycin carbohydrate derivative results in altered pharmacokinetic profiles and reduced toxicities. Thus, the present invention provides compounds with characteristics that are distinct from other drugs in its class such as rapamycin.

Rapamycin carbohydrate derivatives

The invention is directed to isomeric mixtures of cyclosporine analogues that are structurally similar to cyclosporine A. The mixtures possess enhanced efficacy and reduced toxicity over the individual isomers and over naturally occurring and other presently known cyclosporines and cyclosporine derivatives. Embodiments of the present invention are directed toward cis and trans-isomers of cyclosporin A analogs referred to as ISA247, and derivatives thereof. ISA247 isomers and alkylated, arylated, and deuterated derivatives are synthesized by stereoselective pathways where the particular conditions of a reaction determine the degree of stereoselectivity. Stereoselective pathways may utilize a Wittig reaction, or an organometallic reagent comprising inorganic elements such as boron, silicon, titanium, and lithium. The ratio of isomers in a mixture may range from about 10 to 90 percent by weight of the (E)-isomer to about 90 to 10 percent by weight of the (Z)-isomer, based on the total weight of the mixture.

Synthesis of cyclosporin analogs

Use ofC glucose in an analytical assay to monitor glucose metabolism by measurement of labeled exhaled COis provided. A breath test and kit for performing the breath test are described for the diagnosis of diabetic indications and monitoring of glycemic control. The breath test utilizes the measurement of expiredC-labeled COfollowing the ingestion of aC-enriched glucose source.
