This disclosure relates to methods of treating or preventing cystic fibrosis transmembrane conductance regulator (CFTR) mediated diseases such as cystic fibrosis, chronic obstructive pulmonary disease, chronic pancreatitis, chronic bronchitis, asthma, mucus formation, comprising administering an effective amount of a 2-amino-N′-benzylidene-acetohydrazide compound or derivative thereof to a subject in need thereof. In certain embodiments, the 2-amino-N′-benzylidene-acetohydrazide compound is ((E)-N′-(3,5-dibromo-2,4-dihydroxybenzylidene)-2-(m-tolylamino)acetohydrazide; or (E)-N′-(3,5-dibromo-2,4-dihydroxybenzylidene)-2-(p-tolylamino)acetohydrazide.

The present invention relates to a compound for use in a method of treating a disease selected from cystic fibrosis, ulcerative colitis, and irritable bowel syndrome, wherein said compound is an inhibitor of a TMEM16 protein, preferably of TMEM16A and/or TMEM16F.

The present invention features processes for preparing compounds, such as (R)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(1-(2,3-dihydroxypropyl)-6-fluoro-2-(1-hydroxy-2-methylpropan-2-yl)-1H-indol-5-yl)cyclopropanecarboxamide (Compound 1), useful for treating CFTR mediated diseases such as cystic fibrosis.

The present invention provides pyridine and pyrazine derivatives which restore or enhance the function of mutant and/or wild type CFTR to treat cystic fibrosis, primary ciliary dyskinesia, chronic bronchitis, chronic obstructive pulmonary disease, asthma, respiratory tract infections, lung carcinoma, xerostomia and keratoconjunctivitis sire, or constipation (IBS, IBD, opioid induced). Pharmaceutical compositions comprising such derivatives are also encompassed.

Disclosed are compositions and methods for decreasing the viscosity and/or cohesiveness of and/or increasing the liquefaction of excessively or abnormally viscous or cohesive mucus or sputum. The composition contains a protein or peptide containing a thioredoxin monocysteinic active site in a reduced state and optionally further contains a reducing system.

An inhalable microparticles having cysteamine hyaluronate salt is provided. Also a preparation method and a pharmaceutical composition thereof are provided.

Aspects of the disclosure relate to a nucleic acid comprising a heterologous nucleic acid insert flanked by interrupted self-complementary sequences, wherein one self-complementary sequence is interrupted by a cross-arm sequence forming two opposing, lengthwise-symmetric stem-loops, and wherein the other of the self-complementary sequences is interrupted by a truncated cross-arm sequence. Methods of delivering the nucleic acid to a cell are also provided.

Provided are: a method for producing a nasal drop composition suitable for treatment or prevention of a disease or symptom in the nasal cavities; and a nasal drop composition produced by the production method. The nasal drop composition production method characterized by including a mixing step of mixing earthworm castings with water and a collecting step of collecting vaporized water generated from a mixture obtained in the mixing step to obtain a liquid; and the nasal drop composition produced by the production method. It is preferred to further mix an organic substance together with the earthworm castings and the water in the mixing step.
