The Long-Range Synthon Aufbau Module (LSAM) concept is utilized in the crystal engineering of 1:1 cocrystals of trichlorophenols and halogen-substituted anilines. NMR studies show the presence of LSAMs in solution and also the sequence of association of hydrogen bonding and π⋯π stacking interations that constitute the LSAMs.

MAT2 complex is expressed in nearly all tissues and is essential in providing the necessary SAMe flux for methylation of DNA and various proteins including histones. X-ray crystallography and solution X-ray scattering structures of this complex show an unexpected stoichiometry, offering a unique mechanism of regulation and thus providing a gateway for structure-based drug design in anticancer therapies including liver disease.
