摘要:
An improved process for coating implantable medical devices utilizes a number of techniques for improving the stability of therapeutic agents contained within the coating. The stability of the therapeutic agents may be improved by creating substantially solvent-free, amorphous forms of the therapeutic agents.

摘要:
A process for making a compound of formula I wherein the substituents are as described in the specification comprising reacting a ketone of formula II with succinic anhydride and an alkoxide base to form a compound of formula III which is reacted with a compound of formula IV to form a compound of V and reacting with an alcohol to form the corresponding ester of formula VI and reacting the ester with N-methylhydroxylamine.
摘要:
This invention relates to a tramadol N-oxide material, enantiomers and compositions thereof and their use. The tramadol N-oxide material and compositions thereof are pharmacologically useful in treating pain, diarrhea and tussive conditions. The tramadol N-oxide is also subject to less side-effects as compared to pure opiate based compositions, such as abuse liability, tolerance, constipation and respiratory depression. Furthermore, the tramadol N-oxide material when administered orally exhibits analgesia for a longer duration than an equi-analgesic amount of tramadol.
摘要:
An efficient synthesis of quanidines, e.g. of the formula (III), by oxidizing a thiourea, e.g. of the following formula (II): ##STR1## with H.sub.2 O.sub.2 and a molybdenum catalyst to yield an aminoiminomethane sulfonic acid which can then be reacted with an amine followed by optional transamination steps.

摘要:
A process to prepare retinoyl chlorides, e.g., of the following formula (I): ##STR1## under very mild chlorinating conditions by the action of a reagent amount of dimethylchloroformamidinium chloride on a corresponding retinoic acid.
摘要:
A process for the synthesis of a compound of the formula wherein R1 is aryl, heteroaryl, substituted aryl or substituted heteroaryl and R2 is hydrogen, alkyl or aralkyl, or salt thereof.
摘要:
Compounds of the general formula I ##STR1## are disclosed as novel antipsychotic agents. Pharmaceutical compositions and methods of treating convulsions employing such compounds of formula I are also disclosed.
摘要:
A diastereoselective process for known antidepressive compounds (I) via reduction of the corresponding alcohol (VII): ##STR1## whereby the product mixture of diastereomers is surprisingly and unexpectedly rich in the content of the trans configuration (II) over the cis configuration (III) as defined in the following formulae: ##STR2## The preferred reaction conditions include use of a borane complex as the reducing agent and an acidic solvent such as trifuloroacetic acid.
