Melatonin Agonist, MA-1, is administered at effective doses.

Disclosed in the present invention are a substituted nitrogen heterocyclic compound and anesthetic action thereof. Specifically provided a chemical compound as shown in formula I, a stereoisomer thereof, a pharmaceutically acceptable salt thereof, a solvate thereof, a prodrug thereof, a metabolite thereof or a deuterated derivative thereof. The substituted nitrogen heterocyclic compound provided in the present application has good central nervous system inhibition effects, capable of generating sedative, hypnotic and/or general anesthetic effects, and capable of controlling status epilepticus; said substituted nitrogen heterocyclic compound is also characterized by rapid onset of action and rapid recovery, while maintaining positive anesthetic activity; in addition, said substituted nitrogen heterocyclic compound has almost no inhibitory effect on adrenocortical function, low side effects, and resolves technical difficulties in the art. The present invention provides a new selection for clinical screening and/or preparation of sedative, hypnotic and/or general anesthetic drugs and drugs controlling status epilepticus.

The present invention relates to a composition for preventing, improving, or treating fragile X syndrome or related developmental disorders, comprising lisuride, a lisuride metabolite, or a pharmaceutically acceptable salt thereof.

This invention relates to particular substituted heterocycle fused gamma-carbolines, their prodrugs, in free, solid, pharmaceutically acceptable salt and/or substantially pure form as described herein, pharmaceutical compositions thereof, and methods of use in the treatment of diseases involving 5-HT.sub.2A receptor, serotonin transporter (SERT) and/or pathways involving dopamine D.sub.1/D.sub.2 receptor signaling systems, and/or the treatment of residual symptoms.

L-serine, L-serine precursors, L-serine derivatives and L-serine conjugates for treatment, amelioration and/or prevention of protein aggregation/tangles/plaques and diseases associated with protein aggregation/tangles/plaques. In particular, treatments and uses for L-serine, L-serine precursors, L-serine derivatives and L-serine conjugates include Alzheimer's disease (AD), Parkinson's disease, Amyotrophic Lateral Sclerosis (ALS), and Huntington disease (HD).

Disclosed are a quinazolinone derivative, a preparation method therefor, a pharmaceutical composition, and applications. Provided are a compound represented by formula I, a pharmaceutically acceptable salt, a solvate, a crystal form, a eutectic crystal, a stereoisomer, an isotope compound, a metabolite, or a prodrug thereof. Generation or activity of a cell factor can be regulated, and accordingly, cancers and inflammatory diseases can be effectively treated. ##STR00001##

A valerian composition includes valerian and an acidifying agent blended together in a pharmaceutically acceptable hydrogel-forming polymer matrix. An expedited release portion of the dosage form includes 5% to 50% of the valerian and is effective to release the valerian therein within 2 hours from placement in a 0.1 N HCl solution. A sustained release portion of the dosage form includes the remainder of the valerian and is effective to release the valerian therein within 10 hours from placement in a phosphate buffer with a pH of 6.8.
