The present invention relates to tetrahydroquinoline derivatives of the present invention or a pharmaceutically acceptable salt thereof or a prodrug thereof, processes for their preparation, pharmaceutical compositions containing them and their use in the treatment of various disorders which are mediated via the P2X7 receptor.

Tetrahydroquinoline derivatives as P2X7 receptor antagonists

The present invention relates to pyrazolopyridine derivatives which have blocking activities of voltage gated sodium channels as the TTX-S channels, and which are useful in the treatment or prevention of disorders and diseases in which voltage gated sodium channels are involved. The invention also relates to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which voltage gated sodium channels are involved. 

Pyrazolopyridine derivatives as TTX-S blockers

The present invention relates to aryl substituted carboxamide derivatives of formula (I) or a pharmaceutically acceptable salt thereof, which have blocking activities of T-type calcium channels or voltage gated sodium channels as the tetrodotoxin-sensitive (TTX-S) blocker such as Naand Na, and which are useful in the treatment or prevention of disorders and diseases in which T-type calcium channels or voltage gated sodium channels are involved. The invention also relates to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which T-type calcium channels or voltage gated sodium channels are involved.

The present invention relates to arylamide derivatives which have blocking activities of voltage gated sodium channels as the TTX-S channels, and which are useful in the treatment or prevention of disorders and diseases in which voltage gated sodium channels are involved. The invention also relates to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which voltage gated sodium channels are involved. 

Arylamide derivatives as TTX-S blockers

The present invention relates to aryl substituted carboxamide derivatives of formula (I) or a pharmaceutically acceptable salt thereof, which have blocking activities of T-type calcium channels or voltage gated sodium channels as the tetrodotoxin-sensitive (TTX-S) blockers such as Naand Na, and which are useful in the treatment or prevention of disorders and diseases in which T-type calcium channels or voltage gated sodium channels are involved. The invention also relates to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which T-type calcium channels or voltage gated sodium channels are involved. 

The present invention relates to aryl carboxamide derivatives of formula (I), wherein Aris phenyl; Aris aryl; n is 1-4; X is &#x2014;O&#x2014;, &#x2014;S&#x2014;, &#x2014;SO&#x2014; or &#x2014;SO&#x2014;, a prodrug thereof or a pharmaceutically acceptable salt thereof, which have blocking activities of voltage gated sodium channels as the TTX-S channels, and which are useful in the treatment or prevention of such disorders and diseases as pain in which voltage gated sodium channels are involved. The invention also relates to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases as pain in which voltage gated sodium channels are involved. 

Aryl carboxamide derivatives as TTX-S blockers

The present invention relates to picolinamide derivatives which have blocking activities of voltage gated sodium channels as the TTX-S channels, and which are useful in the treatment or prevention of disorders and diseases in which voltage gated sodium channels are involved. The invention also relates to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which voltage gated sodium channels are involved.

Picolinamide derivatives as TTX-S blockers

The present invention relates to novel oxyindole derivatives of formula (I) or a pharmaceutically acceptable salt thereof, processes for their preparation, pharmaceutical compositions containing them and their use in the treatment of various disorders which are mediated via the motilin receptor (GPR38).
