Synthesis of Multifunctionalized 2-Iminothiazolidin-4-ones and Their 2-Arylimino Derivatives
摘要:
Multifunctionalized 2-imino-3-(pyrazol-4-yl)thiazolidin-4-ones and 2-arylimino-3-(pyrazol-4-yl)thiazolidin-4-ones were prepared according to an efficient four-step procedure. The key step of the synthetic pathway involved the cyclization of 2-chloro-N-(pyrazol-4-yl)acetamide intermediate using KSCN or aryl isothiocyanate, respectively. The structure of the title compounds was confirmed on the basis of NMR data and N-15-labeling.
Pharmaceutical compositions and compounds are provided. The compounds of the invention demonstrate anti-proliferative activity, and may promote apoptosis in cells lacking normal regulation of cell cycle and death. In one embodiment of the invention, pharmaceutical compositions of the compounds in combination with a physiologically acceptable carrier are provided. The pharmaceutical compositions are useful in the treatment of hyperproliferative disorders, which disorders include tumor growth, lymphoproliferative diseases, angiogenesis. The compounds of the invention are substituted pyrazoles and pyrazolines.
