The invention discloses compounds of the formula:
1
where n is 1, or 2 to 200 in which case each recurring unit can be the same or different,
B is a protected or unprotected base capable of Watson-Crick or of Hoogsteen pairing.
C is OH or OR′″ where R′″ is a protecting group or an activating group or a lipophilic group or an amino acid or amino amide or nucleoside,
D is H or a protecting group or a lipophilic group or an amino acyl group or nucleoside,
each of R′ and R″, which may be the same or different, is an alkyl or aryl group or R′ and R″ together represent 2 or more chain atoms necessary to complete an unsaturated or saturated ring with X and Y, said ring being optionally substituted and optionally being fused to at least one other ring,
X represents
2
and Y represents
3
or
4
wherein Y′ represents hydrogen or additionally, when R′ and R″ do not together complete a ring, an alkyl or aryl group, and X′, when R′ and R″ together complete a ring, represents hydrogen or forms a bridge with another atom of the ring, or when R′ and R″ do not together complete a ring, represents hydrogen or an alkyl or aryl group as well as a method of analysing a polynucleotide sequence comprising incubating the sequence with a probe comprising a compound of the above invention in which n is 2 or more under suitable hybridisation conditions, and detecting the presence or absence of any hybrid formed.
本发明公开了以下化合物的结构式:1其中n为1,或2至200,此时每个重复单元可以相同也可以不同,B是一种受保护或未受保护的碱基,能够进行Watson-Crick或Hoogsteen配对,C是OH或OR′″,其中R′″是一种保护基、活性基、疏水基、氨基酸、氨基酰基或核苷酸,D是H或一种保护基、疏水基、氨酰基或核苷酸,R′和R″各自可以相同也可以不同,是一种烷基或芳基,或者R′和R″一起代表2个或更多个链原子,以完成与X和Y一起的不饱和或饱和环,该环可选择性地取代,也可选择性地与至少另一个环融合,X代表2,Y代表3或4,其中Y′代表氢,或者当R′和R″不一起完成一个环时,代表烷基或芳基,X′代表氢,或者当R′和R″一起完成一个环时,代表氢或与环的另一个原子形成桥梁,或者当R′和R″不一起完成一个环时,代表氢或烷基或芳基。以及一种分析多核苷酸序列的方法,包括将该序列与上述发明中n为2或更多的化合物构成的探针在适当的杂交条件下孵育,然后检测任何形成的杂交物的存在或缺失。
