The present invention relates to compositions and methods for improving the safety of blood-brain barrier receptor-mediated blood-brain barrier transport.

Described are RNAi agents, compositions that include RNAi agents, and methods for inhibition of an alpha-ENaC (SCNN1A) gene. The alpha-ENaC RNAi agents and RNAi agent conjugates disclosed herein inhibit the expression of an alpha-ENaC gene. Pharmaceutical compositions that include one or more alpha-ENaC RNAi agents, optionally with one or more additional therapeutics, are also described. Delivery of the described alpha-ENaC RNAi agents to epithelial cells, such as pulmonary epithelial cells, in vivo, provides for inhibition of alpha-ENaC gene expression and a reduction in ENaC activity, which can provide a therapeutic benefit to subjects, including human subjects.

In one aspect, compounds of Formulae (I) and (II), or pharmaceutically acceptable salts thereof, are featured; Formula (I), Formula (II) or a pharmaceutically acceptable salt thereof, wherein the variables shown in Formulae (I) and (II) can be as defined anywhere herein.

##STR00001##

The present invention provides compounds having the general structural formula (I) ##STR00001##
and pharmaceutically acceptable derivatives thereof, as described generally and in classes and subclasses herein, and additionally provides pharmaceutical compositions thereof, and methods for the use thereof for the treatment of any of a number of conditions or diseases involving elevated levels of aldosterone or abnormal or excessive fibrosis, such as kidney disease and hypertension.

The present invention relates to a compound selected from (R)-(+)-5-(p-cyanophenyl)-5,6,7,8-tetrahydroimidazo[1,5-a]pyridine and a pharmaceutically acceptable salt thereof, and in particular to the phosphate salt of (R)-(+)-5-(p-cyanophenyl)-5,6,7,8-tetrahydroimidazo[1,5-a]pyridine, both having preferably an enantiomeric excess of the (R) form higher than or equal to 97%. Furthermore, the present invention relates to pharmaceutical compositions comprising the same, their use as a medicament and in methods of treatment of diseases and disorders in humans including women of child bearing potential and pediatric patients in which aldosterone over-exposure contributes to the deleterious effects of said diseases or disorders, as well as processes for preparing said inventive compounds.

The present invention provides a compound of formula (I) or a salt thereof: (Formula (I)) wherein X, L, V, R.sub.1; R.sub.2, R.sub.3 and R.sub.4, are as defined herein. The claimed compounds inhibit the enzyme 11-hydroxysteroid dehydrogenase type 2 (11-HSD2) and as a result are useful in the treatment of hyperkalemia by preventing cortisol from being oxidised to cortisone and thus allowing it to occupy the mineralocorticoid receptor, thus stimulating potassium excretion.
