    Description / Table of Contents: Polynuclear Thiophenes, VIII1). Trypanocidal Diamidines of 2-Phenyl-thionaphtheneThe diamidines of 2-phenyl-thionaphthene with the amidino groups in the positions 4′, 6 (7), 4′,5 (19e), 3′.6 (12g) and 3′,5 (14g) are synthesized. The 1.1-dioxides 20b and 22b of the 4′,6-and of the 4′,5-diamidines are also prepared as well as the corresponding 1,1-dioxides hydrogenated in 2,3-position (21b, 23b). - Both the 4′,6- and the 4′,5-diamidine exhibit in mice a general and outstanding trypanocidal activity which culminates for the 4′,6-compound 7 in the highest activity against T. gambiense.
    Notes: Die Diamidine des 2-Phenyl-thionaphthens mit den Amidinogruppen in 4′.6-(7), 4′.5-(19e), 3′.6-(12g) und 3′.5-Stellung (14g) werden synthetisiert. Vom 4′.6- und vom 4′.5-Diamidin werden die 1.1-Dioxide (20b, 22b) sowie deren 2.3-Dihydro-Derivate (21b, 23b) hergestellt. - Das 4′.6- und das 4′.5-Diamidin zeigen im Mäuseversuch ein ausgezeichnetes trypanocides Wirkungsspektrum (Tab. 1), worin die 4′.6-Verbindung 7 die höchste Wirksamkeit gegen T. gambiense aufweist.
