Abstract
This review focuses on progress in the development of different approaches to the design of steroid ([Formula: see text] estrogens, androgens, cholesterol) conjugates with coordination assemblies of metalloporphyrins, phthalocyanines and related complexes. Porphyrins and phthalocyanines have received considerable attention due to their novel composition, intriguing spectroscopic, photophysical, and redox properties, and potential application in light-harvesting and optoelectronic devices. With the development of more efficient imaging and therapeutic applications, these bio-conjugates are evaluated as multimodality agents (PET, fluorescence imaging) to monitor the mechanism of action of biologically active components in living systems and as agents for molecular recognition, oxygen atom transfer and catalysis. The tetrapyrrole components, which can be coupled via covalent and various non-covalent linkages, may exhibit strong interactions through efficient photo-induced electron and/or energy transfer processes.
