The synthesis and SAR of 2-amino-pyrrolo[2,3-d]pyrimidines: A new class of Aurora-A kinase inhibitors

A new class of Aurora-A inhibitors have been identified based on the 2-amino-pyrrolo[2,3-d]pyrimidine scaffold. Here, we describe the synthesis and SAR of this novel series. We report compounds which exhibit nanomolar activity in the Aurora-A biochemical

Development of the First Covalent Monopolar Spindle Kinase 1 (MPS1/TTK) Inhibitor

Monopolar spindle kinase 1 (MPS1/TTK) is a key element of the mitotic checkpoint and clinically evaluated as a target in the treatment of aggressive tumors such as triple-negative breast cancer. While long drug-target residence times have been suggested to be beneficial in the context of therapeutic MPS1 inhibition, no irreversible inhibitors have been reported. Here we present the design and characterization of the first irreversible covalent MPS1 inhibitor, RMS-07, targeting a poorly conserved cysteine in the kinase's hinge region. RMS-07 shows potent MPS1 inhibitory activity and selectivity against all protein kinases with an equivalent cysteine but also in a broader kinase panel. We demonstrate potent cellular target engagement and pronounced activity against various cancer cell lines. The covalent binding mode was validated by mass spectrometry and an X-ray crystal structure. This proof of MPS1 covalent ligandability may open new avenues for the design of MPS1-specific chemical probes or drugs.

Preparation method for 5-bromo-2-chloro-N-cyclopentylpyrimidine-4-amine

The invention relates to the field of pharmaceutical synthesis, and discloses a preparation method for 5-bromo-2-chloro-N-cyclopentylpyrimidine-4-amine. The method is capable of firstly using 5-bromo-2,4-dichloropyrimidine as a raw material, and preparing the 5-bromo-2-chloro-N-cyclopentylpyrimidine-4-amine through two steps of ammonification and alkylation. The side reactions are less, the yieldand the purity are high, and the quality is stable. Cyclopentylamine is not used, so a defect that difficultly separated by-products are easily generated while the cyclopentylamine is used as an amination reagent is overcome.

PROGNOSTIC BIOMARKERS FOR TTK INHIBITOR CHEMOTHERAPY

The present invention provides a method for identifying a tumor - in a human individual or in an animal - that is susceptible to treatment with a TTK inhibitor, said method comprising: a] providing a sample of a tumor; b] determining the presence of a mutated CTNNB1 gene in said tumor sample, wherein said mutation is located in exon 3 of CTNNB1 and whereby the presence of a mutated CTNNB1 gene indicates that the tumor is susceptible to treatment with a TTK inhibitor. In an alternative aspect, step b] of the above defined method is replaced by the step of determining the presence of a mutated CTNNB1 protein in said tumor sample, wherein said mutation is located in exon 3 of CTNNB1 and whereby the presence of a mutated CTNNB1 protein indicates that the tumor is susceptible to treatment with a TTK inhibitor. In a further alternative, step b] comprises determining an altered expression of a CTNNB1 regulated gene, whereby an altered expression of a CTNNB1 regulated gene indicates that the tumor is susceptible to treatment with a TTK inhibitor.
