    摘要: The present invention describes the design, synthesis and therapeutic use of a variety of novel inhibitors of polyamine transport. The main feature of this class of transport inhibitors is to incorporate a linker or side chain that prevents the uptake of polyamines and helps to conjugate polyamine analogs to form dimers with high inhibitory potency against polyamine uptake. These new compounds incorporate features that are designed to maximize their chemical and metabolic stability and their ability to bind to the polyamine transporter, and to minimize their toxicity by preventing their absorption by the cells. The purpose of such inhibitors is to prevent the uptake or salvaging of circulating polyamines by rapidly proliferating cells such as tumor cells, in order to potentiate the effect of therapeutic inhibitors of polyamine biosynthesis such as alpha-difluoromethylornithene.

    摘要: 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.
