The invention relates to a series of propargylamines, their salts and pharmaceutical compositions containing a compound of formula (III) wherein R.sub.1, R.sub.3 and R.sub.4 are the same or different and represent hydrogen or a straight chain or branched lower alkyl; y is an integer ranging from 0 to 5; z is an integer ranging from 0 to 5; and R.sub.2 is a straight chain or branched alkyl, alkenyl, alkynyl, alkoxy, alkylthio or alkyl sulphinyl group having from 3 to 11 carbon atoms, said group being unsubstituted or substituted with at least one of the substituents selected from hydroxy, aldehyde, oxo, loweracyloxy, halogen, thio, sulfoxide, sulfone, phenyl, halogen-substituted phenyl, hydroxy-substituted phenyl, cycloalkyl having from 3 to 6 carbon atoms and heterocyclic substituents having between 3 and 6 atoms, of which form 1 to 3 are heteroatoms selected from O, S and/or N, and pharmaceutically acceptable salts thereof, in admixture with a pharmaceutically acceptable carrier, excipient or adjuvant. The compounds are useful as selective monoamine oxidase B inhibitors and have demonstrated neuroprotective properties in human and veterinary medicine.
本发明涉及一系列丙炔胺、其盐和药物组合物,其含有公式(III)的化合物,其中R.sub.1、R.sub.3和R.sub.4相同或不同,并表示氢或直链或支链低碳基;y为0到5的整数;z为0到5的整数;R.sub.2为直链或支链烷基、烯基、炔基、烷氧基、烷硫基或烷基亚磺酰基,其具有3到11个碳原子,该基团未被取代或被取代,取代基团至少包括所选取自羟基、醛、氧代、低酰氧基、卤素、硫、亚砜、砜、苯基、卤素取代苯基、羟基取代苯基、具有3到6个碳原子的环烷基和具有3到6个原子的杂环取代基团,其中形式1到3是所选取自O、S和/或N的杂原子,以及其药学上可接受的盐,与药学上可接受的载体、赋形剂或佐剂混合。这些化合物在人类和兽医学中具有选择性单胺氧化酶B抑制剂的用途,并表现出神经保护性质。
