Synthesis routes that can be adapted to large scale synthesis of oligoguanidine compounds such as oligoarginine compounds are described which use a perguanidinylation step to convert a group of .omega.-amino groups to the corresponding guanidinyl groups. These compounds find utility as transport agents. Modified oligoguanidine compounds are also described.

Selon cette invention, des gammes de synthèse peuvent être adaptées à la synthèse à grande échelle de composés d'oligoguanidine tels que ceux décrits, ces synthèses utilisant une phase de perguanidinylation pour convertir un groupe parmi les groupes .omega.-amino en groupes guanidinyle correspondants. Ces composés s'avèrent être utiles comme agents de transport. L'invention porte également sur des composés d'oligoguanidine modifiés.
