Abstract: The present invention provides new methods of treatment for narcolepsy, excessive daytime sleepiness, obstructive sleep apnea, circadian rhythm sleep disorders, sleep and vigilance disorders associated with Parkinson's disease, multiple sclerosis, dementia or attention deficit hyperactivity disorder by administering a therapeutically effect amount of histamine-3 receptor (H3R) inverse agonist, N-[4-(1-Cyclobutylpiperidin-4-yloxy)phenyl]-2-(morpholin-4-yl)acetamide or a pharmaceutically acceptable salt thereof. The present invention further provides use of the said compounds in the manufacture of medicament intended for the treatment of the disorders described herein.

Abstract: The present invention provides a method for treating behavioral and psychological symptoms in patient with dementia comprising administering an effective dose of pure 5-HT6 receptor antagonist, masupirdine or a pharmaceutically acceptable salt thereof either alone or in combination with an acetylcholinesterase inhibitor such as donepezil and NMDA (N-Methyl-D-aspartate) receptor antagonist, memantine. The present invention further provides use of the said compound in the manufacture of a medicament and pharmaceutical compositions comprising the said compounds intended for the treatment of the disorders described herein.

Abstract: The present invention relates to a pharmaceutical composition comprising solid dispersion of amorphous abiraterone acetate and one or more pharmaceutically acceptable excipients, having improved solubility, stability, bioavailability, and no positive food effect.

Abstract: The present invention provides novel functional assay for 5-HT2A, histamine H1 or adrenergic alpha 1b receptors, by measuring intracellular cyclic adenosine monophosphate (cAMP) levels utilizing reporter gene driven cell based assay. The novel assay provides both binding affinity as well as mode of action of compounds in a single set. The novel assay of the invention is useful in identification of compounds acting through 5-HT2A, histamine H1 or adrenergic alpha 1b receptors. Furthermore, the assay offers utility in categorizing compounds in to agonist, partial agonist, inverse agonist and antagonist classes. The novel assay can be scaled up to any high throughput format.
