The present invention also relates to methods of treating ABC transporter mediated diseases using such modulators.
bond through hydrogen selenide (H2Se) and hypobromousacid (HOBr), which can be easily controlled at simulated physiological conditions. This novel strategy provides a circulation regulation system to modulate the sulfilimine bond in peptides and NC1 hexamers, which can offer a substantial system for further study of the physiological function of collagen IV.

TiCl4(thf)2 to give the mono-ligand complexes 5–7. The solid state structures of compounds 4–6 have been determined. Complexes 5–7 have been tested for their potential as ethylene oligomerisation/polymerisation systems in conjunction with MAO activator and benchmarked against the Mitsui phenoxy-imine trimerisation system IV. While the phenoxy-amine complex 6 shows a propensity for polymer formation, the phenoxy-imine
