摘要:
Compounds and a method useful for protection of tissue cells in a mammalian body from irreversible damages due to lactic acidosis caused by oxygen deficiency. The protection is achieved by administering a compound having a cell membrane permeability and/or ability to cross the blood brain barrier and being able to provide a buffering action to prevent an increase in a hydrogen ion concentration over the physiologically acceptable levels.

Novel .alpha.-haloalkylcarbamic acid halides, and a process for the preparation of .alpha.-haloalkylcarbamic acid halides by reacting alkenyl isocyanates with hydrogen halide. The .alpha.-haloalkylcarbamic acid halides obtained by the process of the invention are valuable starting materials for the preparation of surface-coating raw materials, textile coating agents, dyes, drugs and crop protection agents.

N-(2-Aminocyclopentyl)N-alkanoylanilides and their 2-N-oxides of the formula ##STR1## e.g., trans-3,4-dichloro-N-[2-(dimethylamino)cyclopentyl]propionanilide, and their pharmacologically acceptable salts, have been found to possess potent Central Nervous System anti-depressant properties. Many of them are new.These compounds are promising anti-depressant drugs which are characterized by a better therapeutic ratio than imipramine, and long acting activity which may allow longer durations between administrations, e.g., once a day. Pharmaceutical compositions containing these compounds and a process for treating conditions of depression with these compositions are disclosed.

摘要:
Xylylene dicarbamate contains impurities represented by formulas (1) to (4) below at a ratio of less than 100 ppm as a total amount thereof on a mass basis. (In the above-described formulas (1) to (4), R represents a monovalent hydrocarbon group.).
摘要:
The present invention relates to using a two-step (thermolysis) or one-pot process to prepare aliphatic diisocyanates from aliphatic diamines and diaryl carbonates. Polyisocyanates can also be prepared from polyamines and diaryl carbonates. The present synthetic processes do not apply phosgene or highly toxic reagents and chloro-solvents during the entire procedure.
摘要:
Described herein is a process for preparing urethane (meth)acrylates. In a first step, a hydroxyalkyl (meth)acrylate is reacted with a lactone (B) in the presence of at least one zinc compound and/or bismuth compound (C) to produce a resulting zinc-containing product and/or a bismuth-containing product, and, in a further step, the zinc-containing product and/or the bismuth-containing product is reacted with at least one cycloaliphatic or asymmetric aliphatic diisocyanate (D).
