Specifically disclosed is a composition for alleviating ultraviolet irradiation-induced damage which contains one or more kinds of compounds selected from the group consisting of methionine, D-serine and derivatives and/or salts of the same. The aforesaid composition may be an external preparation for the skin, an anti-wrinkle agent, a sunscreen agent, a medicinal composition for treating and/or preventing skin diseases, a food composition or a pharmaceutical product for cataract. In the aforesaid composition for alleviating ultraviolet irradiation-induced damage, the aforesaid methionine may be D-methionine, and the aforesaid D-serine derivative may be D-cycloserine.

The invention describes methods and compositions for alleviating medical afflictions for which anxiety may cause or exacerbate the affliction. A subject suffering from the affliction is treated with a combination of a pharmaceutical compound that enhances learning, and a second pharmaceutical recognized to be useful for treatment of the affliction, wherein D-cycloserine is the pharmaceutical compound that enhances learning. Representative afflictions include pain, mood disorders, anxiety disorders including performance anxiety, insomnia, female sexual dysfunction, chronic fatigue, autism spectrum disorders, fibromyalgia, and attention deficit-hyperactivity disorder.

The invention discloses a transport and enrichment culture medium and belongs to the field of detection. The transport and enrichment culture medium is characterized in that a formula contains beef liver powder, malt extract powder, yeast extract powder, sodium chloride, agar, ferric ammonium citrate, calcium lactate, D-seromycin, 2-ethoxymethylene-3,5-dihydroxy-y-pyrone, vitamin K1, casein phosphopeptides, sterile defiberized sheep blood and distilled water. Compared with the prior art, the transport and enrichment culture medium plays roles in transporting and enriching.

Methods are disclosed for treating dementia, including mild cognitive impairment, via administration of D-cycloserine, or a prodrug thereof, on a tolerance-inhibiting basis. Specifically, by administering D-cycloserine on a tolerance-inhibiting basis, tolerance to D-cycloserine is less likely than would occur via daily administration, enhancing benefits and reducing costs and side effects. Pharmaceutical compositions useful for the treatment of dementia are additionally disclosed.

The invention relates to an application of D-seromycin in preparing medicine for treating Morphine psychological dependence behavior caused by stress, which belongs to the medicine technical field. A glutamic acid system in brain plays an important role in drug addiction process, and N-methyl-D-aspartic acid (NMDA) receptor which can be combined with glutamic acid to play a physiological effect exists in central nervous system. The NMDA receptor can be functionally inhibited by acting on different recognition sites. At present more side effects are brought by completely inhibiting the NMDA receptor, so antagonist which not only can block the pathological activation of the NMDA receptor but also is free from influencing the physiological activity of the NMDA receptor is important to discover. DCS is a serine natural derivative and is combined with a glycine site in NMDA receptor NR1 subunit to play an effect of excitant, so that internal flow of calcium ions in cells can be increased, but no neurotoxicity is produced. Since the prepared medicine not only can partially excite the NMDA receptor, but also is free from influencing the physiological activity, the medicine has small side effect on the human body.

The invention relates to a synthetic method of a D-cycloserine intermediate. According to the method, 3-halo-D-alanine methyl ester or an acid salt of 3-halo-D-alanine methyl ester is prepared from D-serine methyl ester or an acid salt of D-serine methyl ester and a halogenating agent through reaction in an organic solvent, and is an important intermediate for preparing D-cycloserine. The synthetic method adopts a process simple and convenient to operate, is high in safety, mild in reaction condition, high in yield and low in cost, greatly reduces production of waste acid and is quite suitable for industrial production.
