摘要:
The present invention is generally directed to a process to directly prepare pharmaceutically acceptable salts enriched with respect to selected rotameric salts of a basic compound, by creative choice of an acid and a solvent medium. The process is particularly useful in preparing specific rotamers of pharmaceutically useful salts in desired preponderance of a rotamer.
摘要:
A compound represented by the structural formula and pharmaceutically acceptable salts and solvents thereof is disclosed, wherein: the single-dashed line between the ring carbons to which R10 and R34 are attached represents either a single bond or a double bond; the double-dashed line between X and the carbon to which Y is attached represents either a single bond or an absent bond; X is —O— or —NR6— when the double-dashed line represents a single bond; X is H, —OH or —NHR20 when the double-dashed line represents an absent bond; and other parameters are as defined herein. Also disclosed are pharmaceutical compositions and combinations containing said compounds and their uses as thrombin receptor antagonists and binders to cannabinoid receptors.

In an illustrative embodiment, the present invention describes the synthesis of the following compound and similar compounds, in high stereochemical purity by a novel stereoselective alkylation process:
摘要:
A crystalline polymorph of a bisulfate salt of a thrombin receptor antagonist compound, which exhibits a powder x-ray diffraction profile substantially the same as that shown in FIG. 1, or which exhibits a differential scanning calorimtery profile substantially the same as that shown in FIG. 3, and is represented by the formula for Compound 2: and processes for preparing Compound 2 are disclosed. Pharmaceutical compositions comprising the polymorph of the bisulfate salt and at least one excipient or carrier, and methods of using the polymorph of Compound 2 to treat a variety of physiological disorders, such as thrombosis, are also disclosed.

摘要:
In one embodiment, the present invention discloses a process to directly prepare an unequal ratio of rotamers of an acid salt from a basic compound, by creative choice of a solvent medium. The process is particularly useful in preparing specific rotamers of pharmaceutically useful salts in desired preponderance.
