Internalizable insulin-BSA-chlorin E6 conjugate is a more effective photosensitizer than chlorin E6 alone.

Experiments with human hepatoma PLC/PRF/5 cells involving the use of two different tests (colony formation and Trypan blue exclusion) have demonstrated a significantly higher photosensitizing activity of chlorin e6 conjugates with bovine serum albumin (BSA) and internalizable ligand insulin as compared to that of chlorin e6 itself. Receptor-mediated internalization of insulin-BSA-chlorin e6 conjugates ensures greater photosensitization of cells than the binding of those conjugates to cell surface receptors. The suitability of such conjugates permitting the delivery of a photosensitizer to most sensitive cell structures is discussed.

[Studies on the analysis of copper chlorophyll and sodium copper chlorophyllin in imported foods].

The analysis of copper chlorophyll (CuCh) and sodium copper chlorophyllin (CuCh-Na) in imported foods was carried out. Standards of CuCh and CuCh-Na were examined by ultraviolet and visible spectrophotometer. CuCh gave absorption maximum around 650 nm, while CuCh-Na gave around 630 nm. Imported sweets and liqueurs were homogenized and extracted with ethyl acetate. These extracts also gave absorption maxima absorbance around 650 nm or 630 nm. The results suggested that a distinction between CuCh and CuCh-Na in foods was possible by spectrophotometry. Visible spectrophotometric quantitation was also tried. However the estimated levels of CuCh or CuCh-Na in the samples by this method did not meet with those by atomic absorption spectrometry.
