摘要
Amino acids, di- and tri-peptides readily react with selenic acid (H2SeO3, formed during solution of selenium(IV) oxide in water) to give the corresponding ammonium hydroselenites. Most selenites synthesized are very active (0.4-11 mug ml(-1)) against mouse hepatoma MG-22A and readily increase NO concentration in the cultural medium on the HT-1080 line (up to TG(100) = 1500%). The amino-acid hydroselenites studied influenced the cell phenotype. Copyright (C) 2002 John Wiley Sons, Ltd.
