Syntheses and characterizations of a series of novel Ln6Cu24 clusters with amino acids as ligands.

With glycine or L-alanine as ligands, a series of novel 3d-4f heterometallic Ln(6)Cu(24) clusters with the formulas of [Sm(6)Cu(24)(mu(3)-OH)(30)(Gly)(12)(Ac)(12)(ClO(4))(H(2)O)(16)].(ClO(4))(9).(OH)(2).

A tyrosine-modified hypocrellin B with affinity for and photodamaging ability towards calf thymus DNA.

An enhanced photodamaging ability towards CT-DNA was achieved in a tyrosine-modified hypocrellin B by improving the affinity of the sensitizer to DNA.

The photodynamic property improvement of hypocrellin A by chelation with lanthanum ions.

A 1:1 complex of lanthanum ion with hypocrellin A (La3+-HA) possessing high singlet oxygen generation efficiency, large absorbance in the phototherapeutic window, and great water solubility exhibits promising photodynamic properties.
