The 17-membered macrocyclic spermine alkaloids protoverbine ((8S)-8-phenyl-1,5,9,13-tetraazacycloheptadecan-6-one, 1) and its N(9),N(13)-methylene-bridged derivative protomethine ((2S)-2-phenyl-1,5,9,14-tetraazabicyclo[12.3.1]octadecan-4-one, 2) were isolated from Verbascum pseudonobileStoj.etStef. (Scrophulariaceae) and characterized. The synthesis of their racemates is described. The possible role
