The invention relates to novel heterocyclic compounds of general formula (I), as well as their pharmaceutically acceptable salts, and their enantiomers. The invention also relates to the use thereof as a medicinal product, preferably in the prevention and/or treatment of inflammatory diseases with a neurogenic component or use thereof as a cosmetic. The compounds of the present invention act as antagonists of the CGRP-R receptor.

The present invention relates to lipid compounds and uses thereof. In particular, the compounds include a class of cationic lipids having an amine moiety, such as an amino-amine or an amino-amide moiety. The lipid compounds are useful for in vivo or in vitro delivery of one or more agents (e.g., a polyanionic payload or an antisense payload, such as an RNAi agent).

Methods are for treatment of an inflammatory disease of the lung caused by inhalation of a toxic agent or an irritant, such as chlorine inhalational lung injury. The methods include administration of compositions including certain compounds.

Provided is a substituted piperidine compound having an orexin type 2 receptor agonist activity. A compound represented by the formula (I): ##STR00001##
wherein each symbol is as described in the DESCRIPTION, or a salt thereof has an orexin type 2 receptor agonist activity, and is useful as a prophylactic or therapeutic agent for narcolepsy.
