title: New molecular complexes of heterocyclic bis-adducts with bacterial lectins: synthesis and structure-activity relationship studies.
abstract: A strongly antitumour effect has been discovered for lectins of Bacillus bacteria [Bacillus subtilis 668(1 + 2)IMV, Bacillus polymyxa 102(1 + 2) KGU] and for their molecular complexes with some heterocyclic bis-adducts of unsubstituted benzimidazole and 6-methyluracile for the first time. These were tested on the tumours: Lymphosarcoma Plissa, Sarcoma 45, Carcinosarcoma Yokera 256. A new convenient method for the preparation of the heterocyclic bisadducts of imidazole, benzimidazole, uraciles with 1,1,1-trifluoro-2-bromo-2-chloroethane is described. The reactions are catalysed by the 18-crown-6-complex.
