✦ Synopsis
Since synthetic oligonucleotides complementary to mRNA sequences were shown to inhibit Rous sarcoma virus replication, [1] oligonucleotide chemists have synthesized all types of analogues to render oligonucleotides suitable as antisense agents. In this context, platinated oligonucleotides have been [*] Dr.

As a novel type of regulator molecule for DNA-recognizing proteins, a photo-cross-linked oligonucleotide duplex was designed and synthesized. The molecule regulated the activity of a restriction endonuclease by being recognized as a substrate. This type of regulating molecule is regarded as a decoy-

The antitumor drug cisplatin low occurrence of interstrand cross-links in cisplatinated DNA is due to an extremely slow initial platination of guanines involved in d(GC) 2 sequences, rather than to a slow cross-linking reaction.
## Abstract Purified potato starch, cross‐linked with epichlorohydrin (65–5.4 anhydroglucose units per cross‐link) by an iterative method that preserved the native crystalline structure of the starch granule, was exposed to enzymic (__B. subtilis__ α‐amylase at 50°C) and acidic (3 __N__ HCl at 40°C
