The present invention provides a compound of formula (I) or a pharmaceutically acceptable salt thereof; ##STR00001##
a method for manufacturing the compounds of the invention, and its therapeutic uses. The present invention further provides a combination of pharmacologically active agents and a pharmaceutical composition.

Provided are novel FcRn antagonist compositions comprising a variant Fc region that binds specifically to FcRn with increased affinity and reduced pH dependence relative to the native Fc region. Also provided are FcRn antagonists with enhanced CD16 binding affinity. Also provided are methods of treating antibody-mediated disorders (e.g. autoimmune diseases) using the these FcRn antagonist compositions, nucleic acids encoding the FcRn antagonist compositions, recombinant expression vectors and host cells for making the FcRn antagonist compositions, and pharmaceutical compositions comprising the FcRn antagonist compositions.

The invention provide for recombinant AAV vectors comprising a miniaturized human micro-dystrophin gene and methods of using the recombinant vectors to reduce or prevent fibrosis in subjects suffering from muscular dystrophy.

The present inventive concept relates to a pharmaceutical composition for prevention or treatment of fibrosis or a health functional food composition for prevention or alleviation of fibrosis, each composition containing a 1H-pyrazole-3-amide-based compound or a pharmaceutically acceptable salt thereof as an active ingredient. The compound exhibits a fibrosis mitigation effect in fibrosis-induced mouse models, and thus the compositions containing the compound as an active ingredient can be favorably utilized for prevention or treatment of fibrosis.

The present disclosure relates to inhibitors of zinc-dependent histone deacetylases (HDACs) useful in the treatment of diseases or disorders associated with an HDAC, e.g., HDAC6, having a Formula I:

##STR00001##

where R, L, X.sup.1, X.sup.2, X.sup.3, X.sup.4, Y.sup.1, Y.sup.2, Y.sup.3, and Y.sup.4 are described herein.

Disclosed are 9-amino-doxycycline derivatives that target cancer stem cells and inhibit cancer metastasis. These compounds selectively target CSCs, potently inhibit tumor cell metastasis in vivo, with little or no toxicity, and minimize the risk of driving antibiotic resistance. In one embodiment, a 14 carbon fatty acid moiety is covalently attached to the free amino group of 9-amino-doxycycline. The resulting “Doxy-Myr” conjugate is over 5-fold more potent than doxycycline for inhibiting the anchorage-independent growth of MCF7 CSCs. Doxy-Myr did not affect the viability of the total MCF7 cancer cell population or normal fibroblasts grown as 2D-monolayers, showing remarkable selectivity for CSCs. Doxy-Myr did not show antibiotic activity, against Escherichia coli and Staphylococcus aureus. Conjugates having either longer (16 carbon; palmitic acid) or shorter (12 carbon; lauric acid) fatty acid chain lengths had similar activity.

An Embodiment of the invention relates to a compound of the general formula. The compound of formula is suitable for use in a method for treating a disorder relating to the binding of a galectin, such as galectin-3 to a ligand in a mammal, such as a human. Furthermore an embodiment of the present invention concerns a method for treatment of a disorder relating to the binding of a galectin, such as galectin-3 to a ligand in a mammal, such as a human.

Provided herein are compositions and methods for treating or preventing fibrosis.
