Cylindrocyclophane Biosynthesis Involves Functionalization …
Cylindrocyclophanes are a class of cyclophane, a group of aromatic hydrocarbons composed of two benzene rings attached in a unique structure. Cylindrocyclophanes were the first cyclophanes found in nature, isolated from a species of cyanobacteria, and have proven to be an interesting … See more Before the cylindrocyclophanes, the cyclophanes had all been produced synthetically. However, when a culture of the cyanobacteria Cylindrospermum lichenforme was being evaluated for antitumor activity, … See more Cylindrocyclophanes are all [7,7] paracyclophanes, differing only in the functional groups present on C-1, C-14, C-29, and C-33. There are currently 16 cylindrocyclophanes … See more Since the cylindrocyclophanes have such a unique structure and exciting biological possibilities due to their cytotoxicity, there have been numerous efforts to create them synthetically in the laboratory. One of the first attempts was the total synthesis of cylindrocyclophane … See more When cylindrocyclophane A was discovered, it was during an evaluation of the cyanobacteria Cylindrospermum lichenforme for antitumor activity. It was shown that … See more Webcylindrocyclophane A C36H56O6 CID 10348304 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological ... shanon gruchot md
