The synthesis and mesomorphism of di-, tetra- and hexa-catenar liquid crystals based on 2,2′-bipyridine

2,2′-Bipyridines are known to coordinate to a wide variety of metal centres. In this paper, liquid-crystalline two-chained (dicatenar), four-chained (tetracatenar) and six-chained (hexacatenar) bipyridines are synthesised and their mesomorphism is described. For the tetracatenar bipyridines, a full homologous series, from tetramethoxy to tetratetradecyloxy, was synthesised, and the phase diagram showed a classic progression from nematic and smectic C phases at short chain length, through a cubic phase to a columnar phase.

Anthracycline derivatives having inhibitory activity against reverse transcriptase of human immunodeficiency virus

As new compounds are now provided 14-O-(3,4-disubstituted benzoyl)adriamycins which are of low cytotoxicity and exhibit a high activity inhibitory to the reverse transcriptase of human immunodeficiency virus (HIV) and which can inhibit propagation of HIV.
