Diaz-Moscoso, Alejandro et al. published their research in Chemical Communications (Cambridge, United Kingdom) in 2008 | CAS: 53784-83-1

Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin (cas: 53784-83-1) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon–bromine bond is electrophilic in nature. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin. Formula: C42H63Br7O28

Rational design of cationic cyclooligosaccharides as efficient gene delivery systems was written by Diaz-Moscoso, Alejandro;Balbuena, Patricia;Gomez-Garcia, Marta;Ortiz Mellet, Carmen;Benito, Juan M.;Le Gourrierec, Loic;Di Giorgio, Christophe;Vierling, Pierre;Mazzaglia, Antonino;Micali, Norberto;Defaye, Jacques;Garcia Fernandez, Jose M.. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2008.Formula: C42H63Br7O28 This article mentions the following:

Self-assembled cyclodextrin (CD)-DNA nanoparticles (CDplexes) exhibiting transfection efficiencies significantly higher than PEI-based polyplexes have been prepared from homogeneous seven-fold sym. polyaminothiourea amphiphiles constructed on a β-cyclodextrin scaffold. In the experiment, the researchers used many compounds, for example, Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin (cas: 53784-83-1Formula: C42H63Br7O28).
