摘要：

A novel 2'-deoxyuridine analogue with syn-norspermidine at the 5-position, 5-[4-[N,N-bis(3-amino-propyl)amino]butyl]-2'-deoxyuridine (1), has been synthesized from 5-iodo-2'-deoxyuridine. This nucleoside 1 was incorporated into heptadecadeoxynucleotides 5'-d[1(MT)(8)]-3' and 5'-[(TM)(4)1(MT)(4)]-3' (M = 5-methyl-2'-deoxycytidine). The triamine group stabilized duplex and tripler formation of the heptadecadeoxynucleotides with a complementary strand and a target duplex, respectively. The oligonucleotides containing 1 were more resistant to nuclease P1 and snake venom phosphodiesterase than an unmodified heptadecadeoxynucleotide, 5'-d[T(MT)(8)]-3'.
