摘要：
Proteins from Juglans regia L. were isolated. Then, proteins were hydrolyzed with different enzymes. Antiproliferative activity of proteins and of the protein hydrolysates of J. regia L. were evaluated using the sulforhodamine B method. Glutelin and prolamin proteins presented a high antiproliferative activity against cancer cells PC-3 (prostate) and K-562 (leukemia) with values of 43.9 and 84.4g/mL, respectively. The highest inhibitory effect observed was 50% at 0.25g/mL concentration in gastrointestinal digestion with pepsin and corolase pp in a dose-dependent manner against cancer cell UACC62 (melanoma). Pepsin hydrolysate showed inhibitory effects against cancer cell UACC62 (melanoma) with a concentration of 71.0g/mL. The effects were studied in a dose-dependent manner. The hydrolysate obtained with neutrase enzyme presented inhibitory effects against cancer cell UACC62 (melanoma) at a concentration of 25g/mL. Neither proteins nor protein hydrolysates presented cytotoxicity against normal cell assay VERO (epithelial).
