A synthetic antimycotic molecule constituted of a chain of basic units or of a derivative of a chain of n basic units, where each basic unit has the structure: Formula (I) wherein: for each basic unit of the chain, one of either R3 or R4 is a sulphate group； for a plurality of basic units of the chain, at least one of R1, R2, or the one of either R3 and R4 which is not said sulphate group, is a group with antimycotic properties in turn having the structure: Formula (III) - for each basic unit of the chain, R5 is a hydrogen atom, a metallic atom or a functional group with metallic or cationic behaviour； - and at least most of the remaining R1, R2, R3 and R4 of the entire chain are each constituted of a -OH group.
