A convenient synthesis of 5alpha,8alpha,14alpha,17alpha-5,17:8,14-dimethano-5,8,14,17-tetraaza-5,6,7,8,13,14,17,18-octahydrodibenzo[e,e']benzo[1,2-a:3,4-a']dicyclooctene derivatives is described, and the compounds have been fully characterized by NMR; in some cases, the molecular structure has been determined by X-ray crystallography. These compounds represent the first examples of a new class of molecular tweezers.
Toward the library generation of natural product-like polycyclic derivatives by stereocontrolled diversity-oriented synthesis Arya, P.; Quevillon, S.; Joseph, R.; Wei, C.-Q.; Gan, Z.; Parisien, M.; Sesmilo, E.; Reddy, P. T.; Chen, Z. Abstract: Due to the growing interest in small molecules that could help in understanding protein-protein interactions based on signal transduction, the demand for the generation of small-molecule libraries that are inspired by bioactive natural products has grown significantly. Many of these pathways are highly complex and present tremendous challenges with the use of classical tools. A rapid access to natural product-like small molecules having structural complexity and diversity is crucial for systematically dissecting the functions of complex protein networking and understanding cell signaling pathways. The complex nature, the three-dimensional architecture, and the number of protein binding functional groups presented in three-dimensional arrays are some of the attractive features to incorporate in smallmolecule chemical probes to be used as modulators of protein function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
