Disclosed is a DNA encoding a composition of matter of the formula(X)&#x2014;(F)&#x2014;(X)&#x2014;(F)&#x2014;(X)&#x2003;&#x2003;(I)and multimers thereof, in which Fand Fare half-life extending moieties, and d and e are each independently 0 or 1, provided that at least one of d and e is 1; X, X, and Xare each independently -(L)-P-(L)-, and f and g are each independently 0 or 1; P is a ShK peptide analog of no more than about 80 amino acid residues in length; L is an optional linker; and a, b, and c are each independently 0 or 1, provided that at least one of a, b and c is 1. A DNA encoding the ShK peptide analog is disclosed. Also disclosed are an expression vector comprising the DNA, and a host cell comprising the expression vector.

Toxin peptide therapeutic agents

Disclosed is a composition of matter comprising a ShK toxin peptide analog, and in some embodiments, a pharmaceutically acceptable salt thereof. A pharmaceutical composition comprises the composition and a pharmaceutically acceptable carrier. Also disclosed are DNAs encoding the inventive composition of matter, an expression vector comprising the DNA, and host cells comprising the expression vector. Methods of treating an autoimmune disorder and of preventing or mitigating a relapse of a symptom of multiple sclerosis are also disclosed.

DNA encoding chimeric toxin peptide fusion proteins and vectors and mammalian cells for recombinant expression

Disclosed is a composition of matter comprising an OSK1 peptide analog, and in some embodiments, a pharmaceutically acceptable salt thereof. A pharmaceutical composition comprises the composition and a pharmaceutically acceptable carrier. Also disclosed are DNAs encoding the inventive composition of matter, an expression vector comprising the DNA, and host cells comprising the expression vector. Methods of treating an autoimmune disorder and of preventing or mitigating a relapse of a symptom of multiple sclerosis are also disclosed.

Methods of using conjugated toxin peptide therapeutic agents

DNA encoding OSK1 toxin peptide analogs and vectors and cells for combinant expression

Disclosed is a composition of matter of the formula(X)&#x2014;(F)&#x2014;(X)&#x2014;(F)&#x2014;(X)&#x2003;&#x2003;(I)and multimers thereof, in which Fand Fare half-life extending moieties, and d and e are each independently 0 or 1, provided that at least one of d and e is 1; X, X, and Xare each independently -(L)-P-(L)-, and f and g are each independently 0 or 1; P is a toxin peptide of no more than about 80 amino acid residues in length, comprising at least two intrapeptide disulfide bonds; L is an optional linker; and a, b, and c are each independently 0 or 1, provided that at least one of a, b and c is 1. Linkage to the half-life extending moiety or moieties increases the in vivo half-life of the toxin peptide, which otherwise would be quickly degraded. A pharmaceutical composition comprises the composition and a pharmaceutically acceptable carrier. Also disclosed are a DNA encoding the inventive composition of matter, an expression vector comprising the DNA, and a host cell comprising the expression vector. Methods of treating an autoimmune disorder, such as, but not limited to, multiple sclerosis, type 1 diabetes, psoriasis, inflammatory bowel disease, contact-mediated dermatitis, rheumatoid arthritis, psoriatic arthritis, asthma, allergy, restinosis, systemic sclerosis, fibrosis, scleroderma, glomerulonephritis, Sjogren syndrome, inflammatory bone resorption, transplant rejection, graft-versus-host disease, and lupus and of preventing or mitigating a relapse of a symptom of multiple sclerosis are also disclosed.
