This Perspective Article highlights recent theoretical developments, and summarizes the
current understanding of the photolytic properties of cobalamins from a computational point …

Photoactive transition-metal nitrosyl complexes are particularly interesting as potential drugs
that deliver nitric oxide (NO) upon UV-light irradiation to be used, eg, in photodynamic …

The biologically active forms of vitamin B 12, methylcobalamin (MeCbl) and
adenosylcobalamin (AdoCbl), are important cofactors in a variety of enzymatic processes. In …

The methylcobalamin cofactor (MeCbl), which is one of the biologically active forms of
