摘要:
The present invention provides a process for the production of a compound of formula (I) or a salt thereof, wherein R is hydrogen, a straight, branched or cyclic C1-C6 alkyl group or an aryl group which may optionally be substituted. This process comprises: (a) reacting a compound of formula (II), with a compound of formula (III), wherein R is as defined above and X is a leaving group, in the presence of N,N-di-isopropylethylamine.
摘要:
The invention relates to a device for transdermally administering a compound of formula (I), wherein A represents hydrogen or deuterium, R represents a group selected among C1-4alkyl, C3-10cycloalkyl, or phenyl, each of which can be substituted by C1-3alkoxy, fluoride, chlorine, bromine, iodine, nitro, amino, hydroxy, oxo, mercapto, or deuterium, the C atom marked by * (asterisk) being provided in the R configuration. The invention is characterized in that the compound of general formula (I) is provided in a polymer matrix and is released at a dose of 0.5 to 20 mg per day through human skin. The invention further relates to the use of said compounds of formula (I) for producing transdermal medicaments.
摘要:
The invention relates to a compound of general formula (I) wherein A represents deuterium or hydrogen, R represents a group selected from C1-6 alkyl, C3-10 cycloalkyl or phenyl, which can be substituted by C1-3 alkoxy, fluorine, chlorine, bromine, iodine, nitro, amino, hydroxyl, oxo, mercapto or deuterium. The C atom marked with a * (star) can be present in an (R) configuration, in an (S)-configuration or a mixture thereof. The invention is characterised in that the above-mentioned compounds are free bases with a degree of purity of more than 97 wt %. The invention also relates to a method for the production of highly pure compounds of general formula (I) and to the use thereof in the production of medicaments.
摘要:
This invention relates to azaspiro compounds and their use as medications especially for the treatment of chronic, chronic-phlogistic and/or neuropathic pain. A compound that lends itself particularly well to the production of analgesics is 2-azaspiro[4.6]undecane-3-thion.
摘要:
The invention concerns novel derivatives of 3,3-diphenylpropylamines, methods for their preparation, pharmaceutical compositions containing the novel compounds, and the use of the compounds for preparing drugs. More particularly, the invention relates to novel prodrugs of antimuscarinic agents with superior pharmacokinetic properties compared to existing drugs such as oxybutynin and tolterodine, methods for their preparation, pharmaceutical compositions containing them, a method of using said compounds and compositions for the treatment of urinary incontinence, gastrointestinal hyperactivity (irritable bowel syndrome) and other smooth muscle contractile conditions.
摘要:
The compound of formula (I): is provided. It may be produced by subjecting a compound of formula (IV) to a reduction reaction wherein R represents hydrogen, straight or branched C1-C6 alkyl. This compound is a valuable intermediate which may be used in the synthesis of fesoterodine, tolterodine, its active metabolite, and related compounds.
