Water‐soluble organic nanotubes were prepared by convergently conjugating polymers of hydroxyethyl acrylate (HEA) and acrylic acid (AA) to self‐assembling cyclic octapeptides of alternating D and L chirality. The structure of the self‐assembled tubes was characterised in a number of polar solvents, and notably water, by using light scattering, TEM and small angle neutron scattering (SANS) techniques

self‐assembled conjugates of polymers and cyclic peptides can be used as an efficient drug carrier. RAPTA‐C, a ruthenium‐based anticancer drug, was conjugated to a statistical co‐polymer based on poly(2‐hydroxyethyl acrylate) (pHEA) and poly(2‐chloroethyl methacrylate) (pCEMA), which formed the shell of the NTs. Self‐assembly into nanotubes (length 200–500 nm) led to structures exhibiting high activity against

We describe the synthesis of self-assembling cyclic octapeptides of alternating D- and L-chirality conjugated to two poly(2-ethyl-2-oxazoline) chains. The resulting conjugates form nanotubes in water, which are reversibly transformed into microparticles as the temperature reaches the cloud point temperature of the conjugate.

Escherichia coli total lipid extract. From these analyses, we have established that cyclic peptides with charged side chains form large pores while those with neutral side chains form unimeric pores. Furthermore, the cyclic peptides that consist of non-symmetric aminoacid configurations possess a higher membrane activity than the cyclic peptides with a symmetric aminoacid configuration. In addition
