Novel antagonists of toll-like receptor 4 (TLR-4) are provided. More specifically, the novel antagonists of TLR-4 are derived from morphinan. Further, use of said morphinan derivatives in the treatment of diseases and/or disorders mediated by TLR-4, such as autoimmune diseases, inflammation disease and infectious diseases, is provided. Pharmaceutical compositions including said morphinan derivatives are also provided.

The present invention relates to the discovery of a novel opioid modulator effective in reducing pharmacologically induced weight gain associated with atypical antipsychotic use. The present invention provides methods of reducing antipsychotic induced weight gain, methods for suppressing food intake and reducing ghrelin levels induced by atypical antipsychotic medications in a patient.

##STR00001##

A method of producing promorphinan, morphinan, nal-opioid, and nor-opioid alkaloid products through the increased conversion of a promorphinan alkaloid to a morphinan alkaloid. The method comprises contacting the promorphinan alkaloid with at least one enzyme. Contacting the promorphinan alkaloid with the at least one enzyme converts the promorphinan alkaloid to a morphinan alkaloid.

The present invention encompasses improved morphian compositions and methods of use of the improved compositions for modulating neuropathic pain, opioid-induced glial activation, or a combination thereof beyond what is currently known in the art. The methods involve administering the compound of Formula I to a subject.

In some aspects, the present disclosure provides compounds of the formula:

##STR00001##

wherein the variables are as defined herein. In some embodiments, these compounds may be used to reduce the pain of a patient. These compounds may be used in pain relief and show an improved pharmaceutical profile relative to other commonly used opiates and opioid derivatives.
