摘要:
The present invention relates to compounds of formula (I) that are inhibitors of PlKfyve kinase and are therefore useful for the treatment of e.g. neurological diseases, such as e.g. amyotrophic lateral sclerosis (ALS), Parkinson's disease, Alzheimer's disease, Huntington's disease, ADHD, schizophrenia, depression, or bipolar disorder. An exemplary compound is e.g. 7-morpholino-5-(3-phenyl-lH- pyrazol-l-yl)-2-(lH-pyrazol-4-yl)furo[3, 2-b]pyridine (compound 10) Data on the PlKfyve kinase inhibition are provided, e.g.:

increasing popularity of peptides as promising molecular scaffolds for biomedical applications and as valuable biochemical probes makes new methods allowing for their modification highly desirable. We describe herein an optimized protocol based on a sequence of CuAAC click reactions and selective deprotection steps, which leads to an efficient multi-functionalization of syntheticpeptides.

A series of potential inhibitors of the human DNA repair protein O-6-methylguanine-DNA methyltransferase (MGMT) were synthesized, characterized in detail by NMR, and tested for their ability to deplete MGMT activity in vitro. The new compounds, omega-[O-6-R-guan-9-yl]-(CH2)(n)-beta -d-glucosides with R = benzyl or 4-bromothenyl and omega = n = 2, 4, ... 12, were compared with the established inhibitors O-6 -benzylguanine (O-6-BG), 8-aza-O-6-benzylguanine (8-aza-BG), and O-6-(4-bromothenyl)guanine (4-BTG), which exhibit in an in vitro assay IC50 values of 0.62, 0.038, and 0.009 muM, respectively. Potential advantages of the glucosides are improved water solubility and selective uptake in tumor cells. The 4-BTG glucosides with n = 2, 4, 6 show moderate inhibition with an IC50 of ca. 0.5 muM, while glucosides derived from BG and 8-aza-BG showed significantly poorer inhibition compared to the parent compounds. The 4-BTG glucosides with n = 8, 10, 12 were effective inhibitors with IC50 values of ca. 0.03 muM. To understand this behavior, extensive molecular modeling studies were performed using the published crystal structure of MGMT (PDB entry: 1QNT). The inhibitor molecules were docked into the BG binding pocket, and molecular dynamics simulations with explicit water molecules were carried out. Stabilization energies for the interactions of specific regions of the inhibitor and individual amino acid residues were calculated. The alkyl spacer is located in a cleft along helix 6 of MGMT. With increasing spacer length there is increasing interaction with several amino acid residues which play an important role in the proposed nucleotide flipping mechanism required for DNA repair.
