Abstract: A rhodanine derivative having the following general formula (I): ##STR1## wherein R is a mono- or di-alkylamino group having 1 to 6 carbon atoms which may be substituted by a hydroxyl group; an alkenylamino group having 3 to 6 carbon atoms; a phenylamino group, the benzene ring of which may be substituted by a lower alkyl group, a lower alkoxyl group, phenyl group or a halogen atom; or a cyclic amino group which may contain in the ring an oxygen atom or a nitrogen atom to which a lower alkyl group is attached; or a nontoxic salt thereof. The rhodanine derivative has potent platelet aggregation inhibiting activity and aldose reductase inhibiting activity and therefore is useful as a therapeutic agent for diabetic complications.

Abstract: A novel anti-inflammatory drug, which exhibits rapidly a pharmacological activity, maintains the activity for a long time, and is free from a side effect such as a gastrointestinal disorder or a central nervous disturbance is disclosed.The drug comprises a compound of an alkylcarbonyloxyalkylester or alkenylcarbonyloxyalkylester derivative of indolylacetic acid or anilinophenylacetic acid.The compound is prepared by an esterification reaction.

Abstract: A sheet-shape adhesive preparation for promoting tooth-movement in orthodontics comprising a layer of a pharmaceutical composition containing as the active ingredient a prostaglandin (e.g. prostaglandin E.sub.1, prostaglandin E.sub.2, and prostaglandin F.sub.2.alpha.) in admixture with one or more high molecular weight compounds and a flexible base sheet, a process for the preparation thereof, and a method for promoting tooth-movement in orthodontics by applying the sheet-shape adhesive preparation to the mucous membrane of gingiva. Said preparation can be kept for a long period of time without being dissolved in saliva and without irritation or unpleasant feeling when applied to the mucous membrane of gingiva and hence can show the tooth-movement activity of the active prostaglandin for a long period of time.

Abstract: A process for the production of dinitrophenyl ethers having the general formula [III]: ##STR1## wherein, one of R.sub.1 and R.sub.2 is a nitro radical, and the other is a hydrogen atom or a straight-chain, branched-chain or cyclic, saturated or unsaturated hydrocarbon radical containing from 1 to 10 carbon atoms, and R.sub.3 is a radical selected from the group consisting of (i) a straight-chain, branched-chain or cyclic, saturated or unsaturated hydrocarbon radical containing from 2 to 10 carbon atoms, (ii) a straight-chain hydrocarbon radical having one phenyl group as a substituent and containing from 1 to 5 carbon atoms, (iii) a phenyl radical, and (iv) a phenyl radical with one or more than one substituents selected from the group consisting of a nitro group, a halogen group, a saturated or unsaturated hydrocarbon group containing from 1 to 5 carbon atoms and an alkoxy group containing from 1 to 4 carbon atoms, by reacting a compound represented by the formula [I]: ##STR2## wherein, R.sub.1 and R.sub.

Abstract: An inhibitor of aldose reductase which contains, as the effective ingredient, a flavone derivative having the following formula: ##STR1## wherein R.sub.1 is hydrogen atom or hydroxyl group, R.sub.2 is hydroxyl group or methoxyl group or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier. The inhibitor is useful for preventing, reducing or treating complications of diabetes.

Abstract: [S]-(+)-2-acetyl-7-(2,3-epoxypropoxy)benzofuran (SEBF) is prepared by subjecting 2-acetyl-7-hydroxybenzofuran and [R]-glycidol to dehydration condensation in an inert organic solvent in the presence of triphenylphosphine and a dialkyl azodicarboxylate. The [S]-(+)-2-acetyl-7-(2,3-epoxypropoxy)benzofuran can be easily converted into [S]-2-acetyl-7-(2-hydroxy-3-isopropylaminopropoxy)benzofuran ([S]-befunolol) or salts thereof which are useful as a .beta.-adrenergic blocking agent, by reacting it with isopropylamine.

Abstract: The description describes a process for depolymerization of a polysaccharide having a rod-like helical structure, comprising a step for forcing a solution of the polysaccharide in a solvent (solvent A) through a capillary at a high shear rate, to produce a lower molecular weight degraded polysaccharide, which has the same repeating unit and the same helical structure, as those of the original polysaccharide.

Abstract: Diseases of the liver and kidneys in humans and animals may be prevented and treated by administering a therapeutically effective amount of a member selected from the group consisting of one or more proteolytic enzymes, one or more polysaccharide mucopolysaccharide-lysing enzymes, and mixtures thereof, in combination with a pharmaceutically acceptable carrier.

Abstract: A peptide having the structural formula (I): ##STR1## wherein Glx is Glu or Gln, and the following physical properties: (1) Ultraviolet Absorption Spectrum: Max 280 nm.,(2) Ehrlich reaction, Sakaguchi reaction and Pauly's reaction: positive,(3) Basic,(4) Soluble in water, methanol and acetic acid, slightly soluble in ethyl acetate, butyl acetate, ethyl ether, hexane, petroleum ether, benzene and chloroform, and(5) white powderhas a specifically GH-releasing effect and no species-specificity.The peptide is useful not only for human dwarfism and wound repair but also for stimulating a growth of domestic animal.
