The present invention provides a process for the isolation of one or more proteins from a protein solution. The process comprises the steps of: (a) providing a protein solution comprising one or more specific proteins and having a preset pH and a preset ionic strength or conductivity, (b) applying the protein solution to a packed bed or expanded bed column comprising an adsorbent, and (c) obtaining one or more proteins from the column, wherein the protein solution has been supplemented with an alcohol.
Synthesis and Preliminary in Vitro Biological Evaluation of 4-[(4-Hydroxyphenyl)sulfanyl]but-3-en-2-one, a 4-Mercaptophenol Derivative Designed As a Novel Bifunctional Antimelanoma Agent
We report the synthesis and preliminary in vitro biological evaluations of 4-[(4-hydroxyphenyl)sulfanyl]but-3-en-2-one, a compound designed as a potential bifunctional antimelanoma agent, bearing both a tyrosinase-activa table phenolic moiety and a GSH-reactive alpha,beta-unsaturated carbonyl group. Both the E (1) and Z (2) isomers of the synthesized compound proved to be very good substrates of mushroom tyrosinase, reacted quickly with GSH at physiological pH, and showed a significant cytotoxic activity against B16F1 murine melanoma cells.
