    摘要: The invention regards a process for the production of ramoplanin-like derivatives of formula (I): RAMO-NC-CO-R (I), wherein the radical R represents a hydrocarbon radical and the portion RAMO-NH- represents deacylated ramoplanin, any of its factors or ramoplanose. The compound of Formula (I) are obtained by reacting a carboxylic acid R-COOH with deacylated ramoplanin, any of its factors or ramoplanose protected on the ornitine amino groups. New compounds wherein the hydrocarbon radical R is different from those characaterizing the ramoplanin and ramoplanose natural products and their tetrahydro-derivatives are calimed. The new compounds have the same or better antinfective activity, lower haemolytic effect and better tolerability profile than ramoplanin.
