    摘要: Disclosed is an analgesic agent for a non-inflammatory pain disease, which comprises a sialic acid or a pharmaceutically acceptable salt thereof as an active ingredient. The sialic acid which is an active ingredient for the agent has an analgesic effect on a disease model animal of neurogenic pain which is a non-inflammatory pain. Therefore, the analgesic agent is useful as a pharmaceutical agent for the treatment of a non-inflammatory pain disease such as a neurogenic pain disease, e.g. trigeminal neuralgia, postherpetic neuralgia, entrapment neuropathy, complex regional pain syndrome, diabetic neuropathy, traumatic neuropathy, phantom limb pain, central pain after spinal cord injury or stroke, and neuropathy caused by pharmacotherapy or radiation therapy, or the like.

    摘要: An amorphous sialic acid powder is disclosed. It is prepared by rapidly freezing an aqueous solution of sialic acids and freeze-drying the frozen product. It has a melting point of 131.degree.-136.degree. C. (decomposed) and exhibits no peaks inherent to crystals in differential scanning thermal analysis (at 165.degree.-200.degree. C.) and X-ray diffractiometric pattern (in the range of 5.degree..ltoreq.2.theta..ltoreq.40.degree.). The amorphous sialic acid powder is highly reactive and can be used as a raw material for drugs and the like.

    摘要: Racemic modifications of optically active amines are treated with (-)-di-O-isopropylidene-2-keto-L-gulonic acid to form diastereomeric salts. The so-formed diastereomeric salts are separated and chemically decomposed to give the desired enantiomers of the amine. The resolving agent, (-)-di-0isopropylidene-2-keto-L-gulonic acid, is recovered by precipitation from aqueous solution.
