摘要:
The present invention has the objective of providing an infrared reflective film by means of which it is possible to achieve an effective heat-shielding performance with a smaller number of layers than hitherto using a construction employing specified infrared reflective layers. Solution Means The infrared reflective film of the present invention has at least two infrared reflective layers and, of these infrared reflective layers, the center reflective wavelength of at least one infrared reflective layer is between 1200 and 1300 nm. Furthermore, the laminated glass of the present invention is formed by interposing this infrared reflective film between two sheets of intermediate film, and laminating these between two sheets of glass.
摘要:
Disclosed is a process for producing 6-aryloxyquinoline derivatives useful as insecticides or fungicides for agricultural and horticultural use. The process comprises a cyclization reaction step of reacting an anthranilic acid derivative represented by general formula (1) with a kenone in the presence of an acid to obtain a quinolone derivative and a condensation reaction step of reacting the quinolone derivative with a halogen compound or an acid anhydride to obtain a quinoline derivative.

Provided is a pharmaceutical composition for the prevention or treatment of a diarrhea, which comprises as an active ingredient, siastatin B or a siastatin B derivative having a β-glucuronidase inhibitory activity. Siastatin B or the siastatin B derivative is useful as a drug for the prevention or treatment of a diarrhea, which is capable of ameliorating the diarrhea disorders as induced as a side effect when a cancer-bearing patient received the administration of an anticancer chemotherapeutic agent, particularly an anticancer camptothecin derivative acting as a topoisomerase I inhibitor. This composition is effective to prevent or treat such diarrhea as induced by the administration of an anticancer camptothecin derivative to the cancer-bearing patient.
摘要:
The present invention relates to a compound represented by the following general formula (1) (wherein X represents O, S, SO, SO 2 , or NH, Y is a substituted or unsubstituted hydrocarbon residue containing 1 through 6 carbon atoms and having an overall molecular weight of not less than 15 and not more than 400, and the hydrocarbon residue, when the residue is ring, may contain one or two hetero-atoms in the ring, and Z is a carboxyl group , a group derived therefrom or an aliphatic hydrocarbon residue having from 1 to 4 carbon atoms which may be substituted or unsabstituted ) or a pharmacologically acceptable salt thereof (excluding (1R,2S)-2- [ (2R)-(2-acetylamino-2-carboxyethyl) thiomethyl ] -3-oxo-1-cyclopentanecarboxylic acid (cystacyclin)), a method for production thereof and a medicinal use thereof. The compound of the present invention is useful as a neuron differentiation accelerator.
