Effect of an anthocyanidin-zeolite complex (A-Z) was investigated by real-time cell analysis in cultured human epidermoid carcinoma keratinocytes (A431) and human forehead fibroblasts (HFF). A mesoporous zeolite, a potential adsorbent applied in household products, was complexed with an anthocyanidin, extracted from blue flowers ofClitoria ternateaLinn. The A-Z was linearly correlated within a range of 0.05 0.3 mg/ml of the anthocyanidin, analyzed by HPLC, in accordance to Langmuir adsorption isotherm (r= 0.992,p> 0.05). In comparison to zeolite or anthocyanidin alone, A431 and HFF showed significantly cell survival with improved IC50upon exposure to A-Z (p< 0.05). The adsorbed anthocyanidin onto the zeolite reduced the toxic potentials of each.

New Strategy

We propose a new strategy for the preparation of a hybrid catalyst based on the TS-1 zeolite and on glucose oxidase. The design allows to combine all the features of the zeolite with a high enzyme loading. The method is based on the aerosol-assisted self-assembly of TS-1 nanocrystals to form hollow mesoporous zeolite microspheres with tailored texture and good epoxidation activity in water. The latter spheres were subsequently loaded with various amounts of enzymes which were then cross-linked to secure their entrapment. Thus, the hollow spheres were used both as catalysts and as vessels for the enzyme. The chemo-enzymatic formation of epoxides by tandem catalysis is demonstrated.
