Abstract:
The disclosure provides methods of using certain morphinans of Formula (I) that are partial kappa opioid receptor agonists, weak mu opioid receptor agonists, and partial or weak delta opioid receptor agonists in the treatment of kappa opioid receptor-associated diseases and conditions. The disclosure provides methods of treating pruritus, acute seizures, and seizure disorders. The disclosure also provides a method of treating cocaine addiction by administering a particular compound of Formula I, PPL-103, to a cocaine addicted patient.
Abstract:
The present invention relates to a method of mono-alkylating a piperidine nitrogen in a piperidine derivative with a deuterated lower-alkyl, which comprises protecting the piperidine nitrogen with an aralkyl protective group, lower-alkylating the piperidine nitrogen with a deuterated-lower-alkylating agent under neutral or basic condition, and then deprotecting the aralkyl protective group.
Abstract:
Disclosed herein are methods for N -demethylating an N-methylated compound using an enzymatic reaction, rather than, e.g. a chemical modification. Also provided herein are enzymes for performing the reaction.
Abstract:
在氢溴酸右美沙芬的长期商业化生产过程中,需要大量的内-(14 S )-3-甲氧基-17-甲基吗啡喃进行质检方面的应用,然而内-(14 S )-3-甲氧基-17-甲基吗啡喃不稳定,不便于贮藏,也不利于检测工作的进行,因此本领域迫切需要解决这个在生产过程中产生的实际问题。鉴于此本发明公开了一种固体形式的内-(14 S )-3-甲氧基-17-甲基吗啡喃苦味酸盐及其制备方法和用途,即用于检测右美沙芬合成过程中产生的内-(14 S )-3-甲氧基-17-甲基吗啡喃。
Abstract:
The present invention relates to genetically modified plants of the species Papaver bracteatum wherein the type or amount of one or more alkaloids produced by the plants has been modified. Specifically, the genetically modified plants have an increased expression of one or more of thebaine 6-O-demethylase, codeine O- demethylase and/or codeinone reductase relative to wild type P. bracteatum such that the genetically modified poppy plants produce an increased quantity of an alkaloid selected from codeine, oripavine and/or morphine relative to a wild type P. bracteatum. Also provided are progeny plants having the genetically modified poppy plants described above as a parent; mutant or derivative plants of the aforementioned plants; reproductive material derived from, straw produced from, straw concentrate produced from, latex derived from, or one or more isolated cells derived from, the aforementioned plants. Methods for producing an alkaloid from the aforementioned plants are also provided, together with nucleic acid and amino acid sequence variants of the 6-O-demethylase and codeine O-demethylase genes.
Abstract:
The present disclosure generally relates to a process for converting a fused, tricyclic compound to a fused, tetracyclic compound that includes a furan ring therein. More particularly, the present disclosure related to a process for preparing a hydrocodone compound, or a compound structurally related thereto, and in particular (+)-hydrocodone, by subjecting a structurally corresponding sinomeπine starting compound to a super acid-assisted furan ring closure reaction. Formula I, II. Examples of super acids useful in the processes described herein include, but are not limited to, trifluoromethanesulfonic acid (CF 3 SO 3 H), tetrafluoroboric acid (HBF 4 ), fluorophosphoric acid (HPF 6 ), fluorosulfuric acid (FSO 3 H). and fiuoroantimonic acid (HSbF 8 ), fluorophosphoric acid (FP(O)(OH) 2 ) as well as combinations thereof.
Abstract:
Compounds of formulas (A) and (B) are disclosed. The compounds of this invention are useful for ameliorating the side effects of therapeutic opiates.
Abstract:
This invention relates to a tamper-resistant transdermal-delivery device comprising an opioid, or a pharmaceutically acceptable salt thereof, and an acyl opiod antagonist, or a pharmaceutically acceptable salt thereof. The transdermal-delivery device allows an analgesically effective amount of the opioid, or a pharmaceutically acceptable salt thereof, to be transdermally administered to a patient. The invention further relates to methods for treating or preventing pain in a patient comprising contacting the skin of a patient in need thereof with the transdermal-delivery device of the invention for an amount of time sufficient to treat or prevent pain. The invention further relates to acyl opioid antagonists.
Abstract:
The present invention relates to opioid and opioid-like compounds, and pharmaceutical formulations containing the same and methods of use thereof. Uses of the present invention include, but are not limited to, use for the prevention and treatment of septic shock and other disorders. The compounds described herein can be water soluble and can act through mechanisms mediated through pathways other than opiate receptors.
