Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with no known cure. Aggregates of the nuclear protein TDP-43 have been recognized as a hallmark of proteinopathy in both familial and sporadic cases of ALS. Post-translational modifications of this protein, include hyperphosphorylation, cause disruption of TDP-43 homeostasis and as a consequence, promotion of its neurotoxicity. Among the kinases involved in these changes, cell division cycle kinase 7 (CDC7) plays an important role by directly phosphorylating TDP-43. In the present manuscript the discovery, synthesis, and optimization of a new family of selective and ATP-competitive CDC7 inhibitors based on 6-mercaptopurine scaffold are described. Moreover, we demonstrate the ability of these inhibitors to reduce TDP-43 phosphorylation in both cell cultures and transgenic animal models such as C. elegans and Prp-hTDP43 (A315T) mice. Altogether, the compounds described here may be useful as versatile tools to explore the role of CDC7 in TDP-43 phosphorylation and also as new drug candidates for the future development of ALS therapies.

6-mercaptopurine (6-MP) is the first active metabolite inhibitor shown to suppress cancer cells. The aim of this study is to investigate the bioactivity of 6-MP derivatives and discover new anti-cancer agents. Four 6-mercaptopurine (6-MP) derivatives were synthesized and their anti-cancer activities were analyzed. All of the compounds showed anti-proliferative effects against HepG2 and A2780 cancer cells. Among the synthesized derivatives, 6-((naphthalen-2-ylmethyl)thio)-9H-purine (NMSP) which possessing a β-naphthalene, showed better anti-cancer activity than other compounds, with an IC50 value 6.09μg/mL. NMSP could induce S phase cell cycle arrest and apoptosis in HepG2 cells. Western blot analysis indicated that NMSP induced apoptosis is mitochondria-dependent. The novel 6-MP derivative discovered in this study is a promising drug candidate to be used as an anti-cancer agent.

A simple method was established for the preparation of thio-substituted thionucleobases using room temperature ionic liquids (RTILs) such as 1-butyl-3-methylimidazolium trifluoroacetate [BMIM]+[CF3COO]- and 1-methoxyethyl-3-methylimidazolium trifluoroacetate [MeOEtMIM]+[CF3COO]- as solvents and catalysts without any other catalyst. These reactions proceeded efficiently in RTILs with excellent yield of products. RTILs can be recycled and reused effectively without further purification.
