摘要:
The invention relates to the use of 2-(N-(2-aminoethyl)amino)acetic acid derivatives of the formula I ##STR1## in which R denotes, for example, phenyl or thienyl, and their pharmacologically acceptable acid addition salts as pharmacological active compounds.
摘要:
There are disclosed novel compounds of the formula ##STR1## where X is hydrogen, loweralkyl, loweralkoxy, hydroxy, halogen, nitro or trifluoromethyl; R.sub.1 is hydrogen or loweralkyl; R.sub.2 is hydrogen, loweralkyl, arylloweralkyl or --(CH.sub.2).sub.m R.sub.7 wherein m is 1, 2 or 3 and R.sub.7 is cyano or amino; R.sub.3 and R.sub.4 are independently hydrogen or loweralkyl; R.sub.5 and R.sub.6 are independently hydrogen or loweralkyl, or R.sub.5 +R.sub.6 taken together with the carbon atom to which they are attached constitute a cyclobutane, cyclopentane, cyclohexane, cycloheptane, pyrrolidine, piperidine, morpholine or thiomorpholine ring, or R.sub.5 is hydrogen and R.sub.6 is aryl or --CH.sub.2 OR.sub.8 wherein R.sub.8 is hydrogen, loweralkyl or loweralkylcarbonyl, which are useful for enhancing memory.
摘要:
There are disclosed compounds of the formula ##STR1## where X and Y are independently hydrogen, loweralkyl, loweralkoxy, hydroxy, halogen, trifluoromethyl or nitro; R.sub.1 is hydrogen or loweralkyl; R.sub.2 is hydrogen, loweralkyl, loweralkylcarbonyl or arylcarbonyl; and R.sub.3 is hydrogen, loweralkyl, arylloweralkyl, ##STR2## loweralkylcarbonyl or arylcarbonyl, n being an interger of 1 to 6 inclusive and Z being hydrogen, loweralkyl, loweralkoxy, hydroxy or halogen; which are useful as hypotensive agents.
摘要:
In a process for preparing isosorbide-5-nitrate, isosorbide is reacted with an aliphatic carboxylic acid, with the formation of an acylation mixture. The acylation mixture is then nitrated, and the resulting nitration mixture is hydrolyzed and/or transesterified in order to split off acyl groups. The product is used in treatment of angina pectoris.
