The invention concerns biotin derivatives of general formula (I), wherein: R
1
represents a specific compound; X
1
represents a carbonaceous chain, preferably of 1 to 10 carbon atoms, substituted or not, optionally comprising one or several carbonyl or oxycarbonyl groups, and/or a —NH— group, in particular a chain of formula —HN(CH
2
)
n
—O—CO wherein n is an integer between 1 and 5 and optionally comprising one or several ether, amide and/or amino functions; Y represents a hydrocarbon chain of 1 to 5 carbon atoms, substituted or not; R
2
represents a hydrogen atom, or a protecting group, in particular R
2
represents an alkyl group of 1 to 5 carbon atoms. The invention is useful as vectors, in particular for implementing methods for detecting interactions between biological compounds, and in pharmaceutical compositions.
本发明涉及一般式(I)的生物素衍生物,其中:R1代表特定化合物;X1代表一个碳链,最好是由1到10个碳原子组成,可以取代或不取代,可选地包括一个或多个羰基或氧羰基基团,和/或一个—NH—基团,特别是一个具有公式—HN(CH2)n—O—CO的链,其中n是1到5之间的整数,可选地包括一个或多个醚、酰胺和/或氨基功能基团;Y代表一个由1到5个碳原子组成的烃链,可以取代或不取代;R2代表一个氢原子,或一个保护基团,特别是R2代表1到5个碳原子的烷基基团。该发明可用作载体,特别是用于实施检测生物化合物之间相互作用的方法,以及在药物组合物中的应用。
