Abstract: Mechanical interlocking of molecules (catenation) is a nontrivial challenge in modern synthetic chemistry and materials science1,2. One strategy to achieve catenation is the design of pre-annular molecules that are capable of both efficient cyclization and… read more here.

Abstract: A set of two cyclic [2]catenane dimers were self-assembled in aqueous media via selective hydrazone condensation, by means of either one-pot or post-functionalization procedures. Considering that each catenane is composed of two thirty-six member rings,… read more here.

DOI: 10.7554/elife.81786
Abstract: Type II topoisomerases modulate chromosome supercoiling, condensation, and catenation by moving one double-stranded DNA segment through a transient break in a second duplex. How DNA strands are chosen and selectively passed to yield appropriate topological… read more here.
