Cylindrocyclophanes

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 group of compounds to study due to their unusual molecular structure and intriguing biological possibilities, especially its cytotoxicity to some cancer cell lines.
