Novel derivatives of 6-mercaptopurine: Synthesis, characterization and antiproliferative activities of S-allylthio-mercaptopurines
摘要:
Biologically active S-allylthio derivatives of 6-mercaptopurine (6-MP) and 6-mercaptopurine riboside (6-MPR) were synthesized. The products, S-allylthio-6-mercaptopurine (SA-6MP) and S-allylthio-6-mercaptopurine riboside (SA-6MPR) were characterized. The antiproliferative activity of the new prodrugs was tested on human leukemia and monolayer cell lines, and compared to that of their parent reactants. The new prodrugs acted by a concentration-dependent mechanism. They inhibited cell proliferation and induced-apoptosis more efficiently than the parent molecules. Leukemia cell lines were more sensitive to the new prodrugs than monolayer cell lines. Higher hydrophobicity of the derivatives improves their penetration into cells, where upon reaction with glutathione, S-allylthioglutathione (GSSA) is formed, and 6-MP or 6-MPR is released for further processing.

The invention provides novel mercaptopurine derivatives, e.g., S-allylthio-6-mercaptopurine and S-allylthio-6-mercaptopurine 9-riboside, as well as pharmaceutical compositions thereof. These compounds are highly efficient anti-proliferative agents, thus can be useful for treatment of various diseases or disorders, in particular, proliferative, inflammatory, skin and immune diseases or disorders.
