摘要

综述了硼磷酸DNA和RNA寡核苷酸的重要化学和生化性质。立体规则的硼磷酸盐低聚物可以用酶法合成,并与DNA形成稳定的双聚体。化学合成的完全硼化的、非立体规则的寡胸苷酸与聚(A)形成杂合体,其熔点比寡胸苷酸:聚(A)低,但它们仍然可以支持RNA酶H介导的RNA裂解。

Boranophosphate nucleic acids--a versatile DNA backbone.

Important chemical and biochemical properties of boranophosphate DNA and RNA oligonucleotides are reviewed. Stereoregular boranophosphate oligomers can be synthesized enzymatically and form stable duplexes with DNA. Fully boronated, non-stereoregular oligothymidylates, synthesized chemically, form hybrids with poly(A) that have lower melting points than oligothymidylate:poly(A), yet they nevertheless can support the RNase H mediated cleavage of RNA.
