Improved Process for Paroxetine Hydrochloride Substantially Free from Potential Impurities
摘要:
An efficient process for production of paroxetine hydrochloride hemihydrate 1, a selective 5-hydroxytryptamine (serotonin) reuptake inhibitor, is described. Identification and control of potential impurities and establishment of efficient downstream workup procedures enabled us to produce paroxetine hydrochloride hemihydrate 1 efficiently.

The present invention provides a carbostyril compound represented by General Formula (1)
or a salt thereof, wherein A is a direct bond, a lower alkylene group, or a lower alkylidene group; X is an oxygen atom or a sulfur atom; R
4
and R
5
each represent a hydrogen atom; the bond between the 3 and 4 positions of the carbostyril skeleton is a single bond or a double bond; R
1
is a hydrogen atom, etc; R
2
is a hydrogen atom, etc; and R
3
is a hydrogen atom, etc. The carbostyril compound or salt thereof of the present invention induces the production of TFF, and thus is usable for the treatment and/or prevention of disorders such as alimentary tract diseases, oral diseases, upper respiratory tract diseases, respiratory tract diseases, eye diseases, cancers, and wounds.

A heterocyclic compound or a salt thereof represented by the formula (1):
where R
2
represents a hydrogen atom or a lower alkyl group;
A represents a lower alkylene group or lower alkenylene group; and
R
1
represents an aromatic group or a heterocyclic group. The compound of the present invention has a wide treatment spectrum for mental disorders including central nervous system disorders, no side effects and high safety.
The present invention discloses compounds of formula (I), or pharmaceutically acceptable salts or prodrugs thereof, which inhibit the poly(ADP-ribose) polymerases (PARP) and therefore are useful for treating diseases, disorders, and conditions related to PARP. The present invention also discloses pharmaceutical compositions comprising a compound of formula (I), and methods of using such compounds to inhibit PARP enzymes, and to treat diseases, disorders, and conditions related to PARP.
