- COMBINATIONS OF ESZOPICLONE AND TRANS 4-(3,4-DICHLOROPHENYL)-1,2,3,4-TETRAHYDRO-N-METHYL-1-NAPTHALENAMINE OR TRANS 4-(3,4-DICHLOROPHENYL)-1,2,3,4-TETRAHYDRO-1-NAPTHALENAMINE, AND METHODS OF TREATMENT OF MENOPAUSE AND MOOD, ANXIETY, AND COGNITIVE DISORDERS
-
One aspect of the present invention relates to pharmaceutical compositions containing two or more active agents that when taken together can be used to treat, e.g., menopause, mood disorders, anxiety disorders, or cognitive disorders. The first component of the pharmaceutical composition is a sedative eszopiclone. The second component of the pharmaceutical composition is trans 4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-N-methyl-1-napthalenamine or trans 4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-napthalenamine. The present invention also relates to a method of treating menopause, perimenopause, mood disorders, anxiety disorders, and cognitive disorders.

- A new and simplified process for preparing N-[4-(3,4-dichlorophenyl)-3,4- dihydro-1(2H)-naphthalenylidene]methanamine and a telescoped process for the synthesis of (1S-cis)-4-(3,4-dichlorophenol)-1,2,3,4-tetrahydro-N-methyl-1- naphthalenamine mandelate: Key intermediates in the synthesis of sertraline hydrochloride
-
N-[4-(3,4-Dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenylidene]-methanamine, sertraline imine (3), is an intermediate for the synthesis of Zoloft, sertraline hydrochloride (1). A cleaner, simpler, and more efficient alternative to the Schiff base-mediated formation of sertraline imine has been developed and is presented in this paper. The condensation reaction between 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalone, sertraline tetralone (2), and monomethylamine was carried out in ethanol, without the need for classical dehydrating agent, such as TiCl4, or more novel approaches, such as molecular sieves, both of which produce hazardous byproducts and solid wastes. The low solubility of the imine 3 in this type of solvent is exploited, such that the reaction equilibrium favorably enhances the imine formation. Furthermore, an improved and highly selective catalytic reduction of 3 with Pd/CaCO3 catalyst in ethanol as the reaction solvent, followed by the resolution of the racemic cis isomer (6) with D-(-)-mandelic acid results in a more efficient telescoped commercial process to (1S-cis)-4-(3,4-dichlorophenol)- 1,2,3,4-tetrahydro-N-methyl-1-naphthalenamine mandelate, sertraline mandelate (4). This new process has been implemented commercially and eliminates the use of hazardous material such as TiCl4, significantly reduces undesirable byproducts, reduces the number of intermediate isolations, and improves the overall process yield and productivity on industrial scale.

- IMPROVED SYNTHESIS OF RACEMIC SERTRALINE
-
The present invention relates to the use or natural vegetable flavouring components as flavouring agents in chewing gum coating. The addition of a natural vegetable component to a chewing gum coating results in increased flavour sensation. The invention also relates to a method for the preparation of a chewing gum wherein the coating comprises a natural vegetable component as flavouring agent. The chewing gum comprises a) an insoluble gum base; b) a water soluble portion; c) a coating comprising a flavouring agent wherein at least 10% by weight of the flavouring agent is a natural vegetable flavouring agent comprising plant cellular material.

- Nontricyclic Antidepressant Agents Derived from cis- and trans-1-Amino-4-aryltetralins
-
The need for drugs that lack the obtrusive and limiting side effects of the tricyclic antidepressants has prompted the search for agents with greatly enhanced selectivity for specific mechanisms believed to be essential for antidepressant efficacy.The potential role of derangements of 5-HT pathways in the etiology of depression has long been suspected and has given impetus to the development of newer compounds that accentuate inhibition of serotonin reuptake.This paper presents structure-activity relationship for a series of cis-1-amino-4-(substituted-aryl)tetralins, which are surprisingly potent and selective inhibitors of serotonin uptake in in vitro models.These compounds are pharmacologically distinct from corresponding members of the trans series, which also potently block uptake of dopamine and norepinephrine.The activity in both cis and trans series is stereospecific, being restricted to the cis-(1S,4S) and the trans-(1R,4S) enantiomers.
