The invention discloses compounds of formula I   The compounds of formula I are TRPV1 antagonists and are useful as active ingredients of pharmaceutical compositions for the treatment of pain and other conditions ameliorated by the inhibition of the vanilloid receptor TRPV1.

TRPV1 vanilloid receptor antagonists with a bicyclic portion

The invention discloses compounds of Formula (I). The compounds of formula (I) are TRPA1 antagonists and are useful as active ingredients of pharmaceutical compositions for the treatment of pain and other conditions ameliorated by the inhibition of TRPA1 receptors. 

Sulfonamide TRPA1 receptor antagonists

The present invention provides compounds of formula (I): wherein A and Z are as defined in the description, along with methods for preparing such derivatives and their use for the treatment of inflammatory diseases such as neuropathic pain. 

Biarylcarboxyarylamides as vanilloid-1 receptor modulators

The invention provides compounds of formula (I), wherein Y, R, n and X are as defined in the description, a process for their preparation and pharmaceutical compositions containing them. The compounds of formula (I) inhibit the Transient Receptor Potential Vanilloid 1 (TRPV1), which plays a pivotal role in the development of post-inflammatory analgesia, therefore they can be used as analgesic and anti-inflammatory drugs. 

VR1 vanilloid receptor antagonists with a iononic substructure

The invention relates to compounds of formula (I) in which R is selected from halogen, alkyl, alkoxy, aryl and heteroaryl; Ris selected from 2-hydroxyethyl, 2,3-dihydroxypropyl, 3-hydroxypropyl, 2,2-dihydroxyethyl, 3,3-dihydroxypropyl, 1,3-dioxolane-ethyl, 1,3-dioxane-methyl, 1,3-dioxolane-methyl, 1,3-dioxane-ethyl, 3-fluoro-2-hydroxypropyl, 3-carboxy-2-hydroxy-propyl, 3-chloro-2-hydroxypropyl, 2-hydroxypropyl, 2-hydroxy-propen-2-yl, morpholinoethyl, piperazinoethyl, hydroxymethyl, benzyl, 4-(hydroxymethyl)benzyl, 4-chlorobenzyl, 4-fluorobenzyl, and 4-hydroxybenzyl. Ris te/t-butyl or trifluoromethyl; R3 is independently selected from hydrogen, carboxy, cyano, alkyl or hydroxyalkyl, The compounds of formula (I) can be used for the preparation of pharmaceutical compositions for the therapy of inflammatory states, such as chronic neuropathic pain, over-active bladder syndrome, tumor pain, hemorrhoids, inflammatory hyperalgesia, post-intervention pain, dental extraction, airway and gastro-intestinal diseases.
