Synthesis of Stable Analogues of Thiamine Di- and Triphosphate as Tools for Probing a New Phosphorylation Pathway
摘要:
Thiamine (vitamin B1) is an essential nutritional factor metabolized inside the body in its mono-, di-, and triphosphate forms. Although the action of thiamine and thiamine diphosphate have been intensely investigated, many questions remain unanswered and the role of thiamine triphosphate is still especially unknown. To probe recent hypotheses on the implication of thiamine triphosphate in a new phosphorylation pathway involving synaptic proteins, we synthesized a series of thiamine di- and triphosphate analogues that are resistant to both enzymatic and chemical hydrolyses. The key step in the preparation of the title compounds is the coupling of thiamine propyl disulfide with adequately protected methylenebisphosphonic acid, the corresponding triphosphate analogue, and difluoromethylenebisphosphonic acid.
The present invention is directed to formulations comprising 3-(pyrrol-2-ylmethylidene)-2-indolinone derivatives that modulate the activity of protein kinases (“PKs”). Methods of treating diseases related to abnormal PK activity utilizing the formulations comprising these compounds and methods of making these formulations are also disclosed.
