Abstract:
This invention provides compounds of formula I-A or I-B: wherein HY, G1, G2, R2, R12, W1, W2, n, and Ring A are as described in the specification. The compounds are inhibitors of PI3K and/or mTor and are thus useful for treating proliferative, inflammatory, or cardiovascular disorders.
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing an asymmetric catalyst useful for synthesis of an optically active amino acid derivative by an asymmetric reaction, and an optically active amino acid derivative useful in the fields of pharmaceuticals, agrochemicals, high-functional materials and the like, in a high yield and in a high purity.SOLUTION: The asymmetric catalyst is composed of a specific dibenzazepine derivative containing an optically active quaternary ammonium salt. The method for producing an optically active amino acid derivative includes carrying out asymmetric reactions such as an asymmetric aldol reaction, an asymmetric Mannich addition reaction, an asymmetric halogenation reaction, an asymmetric aminoxylation reaction, an asymmetric hydroxyamination reaction, an asymmetric Michael addition reaction or an asymmetric conjugated addition reaction.
Abstract:
PURPOSE:To obtain an optical recording medium which can reversibly repeat coloration and decoloration, is excellent in heat stability, can keep a colored state for a long time, has a long lifetime, and is capable of writing and erasing. CONSTITUTION:The objective photochromic crown compound is represented by the general formula (wherein X is O or S; R is hydrogen or halogen; R is 1-8C alkyl; R is hydrogen, alkoxyl, nitro or halogen; (n) is an integer of 1-5; and (m) is 0 or an integer of 1-5). A recording layer made from this compound is formed on a base to form the objective optical recording medium.
Abstract:
PURPOSE:An inhibitor of blood platelet aggregation promoting dissociation of blood platelet aggregation bulk in organism closely related to diseases such as arteriosclerosis, metastasis of cancer, etc., having excellent preventing effects on thrombosis, containing gliotoxin as an active ingredient. CONSTITUTION:The titled inhibitor containing glitoxin shown by the formula as an active ingredient. Oral administration, intravenous injection, etc. are preferable as administration method. Even if gliotoxin to be administered is not pure but a crude substance from a filtrate of culture mixture, it has no bad influence on inhibitory effect on blood platelet aggregation. Glitotoxin as the active ingredient can be produced by a microorganism or by chemical synthesis.
