Hexavinyloge Porphyrine mit aromatischen 30π‐Elektronensystemen

Abstract: ZUSCHRIFTENLosungen in 0.05%igem Tween-80/H20 untersucht. Die Losungen wurden durch Filtration durch ein Acrodisc-Filter (0.45 p) sterilisiert. Die Zellinien wurden nach Standardtechniken geziichtet und versorgt. Zur Bestimmung der Cytotoxizitat wurde das National Cancer Institute(NC1)-Protokoll verwendet [lo]. Die Cytotoxizitdt wird als ED,, in pgmL-' angegeben, d. h. als die Konzentration der Verbindung die nach drei Tagen 50% des Zellwachstums inhibiert hat. Das Wachstum fester Tumorzellinien wurde mit Kris… Show more

“…In recent years, increasing attention has focused on the study of so-called expanded porphyrins. Much of our own effort in the area, like that of others, has been devoted to the generation of ever larger π-conjugated polypyrrolic systems. This has led to the synthesis of macrocyclic compounds such as turcasarin, octaphyrin, , vinylogous porphyrins, and torand-type expanded porphyrins as well as linear oligopyrroles and nonplanar polypyrrolic compounds . Among the strategies currently employed to generate large polypyrrolic macrocycles, those predicated on the use of Schiff-base chemistry have a number of advantages, including versatility and ease of synthesis. Indeed, this approach has been used to prepare a range of interesting expanded porphyrin systems, including accordion porphyrins, texaphyrins, and the [2 + 2] macrocycles 1 and 2 …”
