Page/Page column 35; 39; 40, (2019/02/25)
The present invention relates to a process to prepare propylene amines of the formula NH2-(A-NH-)pR, wherein R is a hydrogen atom or an alkyl group, p is at least 1 when R is an alkyl group, and at least 2 when R is a hydrogen atom, or derivatives or precursors thereof wherein one or more units -NH-A-NH-may be present as a cyclic urea unit. (I) or a cyclic unit (ll) or between two units –NH-A-NH-a carbonyl bond is present, each unit –A-can be independently an alkylene unit and at least one unit –A-is a -C3H6- unit, wherein each -C3H6- unit can be linear or branched, by reacting (i) at least one of a hydroxy-functional compound chosen from the alkanolamine-functional compounds, and dihydroxyalkylene compounds, with (ii) an amine-functional compound,in the presence of (iii) a carbon oxide delivering agent, wherein at least one of the alkanolamine-functional compound, the amine-functional compound and/or the carbon oxide delivering agent contains at least one alkylene unit (A) that is a propylene unit

Truncated aminoglycoside-coenzyme A bisubstrate analogues were efficiently prepared using a convergent approach where the amine and the thiol are coupled in one pot with the addition of a linker, without the need for protecting groups. These derivatives were tested for their effect on the activity of the resistance-causing enzyme aminoglycoside 6′-N-acetyltransferase Ii, and key structure-activity relationships are reported. Moreover, one of the inhibitors is able to block aminoglycoside resistance in cells expressing this enzyme.
