title: Covalent analogues of DNA base-pairs and triplets. Part 2: synthesis and cytostatic activity of bis(purin-6-yl)acetylenes,-diacetylenes and related compounds.
abstract: The title bis(purin-6-yl)acetylenes, -diacetylenes, -ethylenes and -ethanes were prepared as covalent base-pair analogues starting from 6-ethynylpurines and 6-iodopurines by cross-coupling and homo-coupling reactions and hydrogenations. The bis(purin-6-yl)acetylenes and -diacetylenes exhibited significant cytostatic activity in vitro (IC(50)=0.4-1.0 micromol/l).
