Abstract
Description
[Technical Field]
[0001] The present invention relates to a pharmaceutical composition comprising a heterobicyclic compound that inhibits Yes-associated protein (YAP)-transcriptional enhancer associate domain (TEAD) binding. The compound according to the present invention can directly inhibit YAP-TEAD binding in the Hippo pathway, which plays a key role in the development of cancer. [Background technology]
[0002] The Hippo signaling cascade is an important pathway for cancer development and tumor maintenance. YAP and tafazzin (TAZ) are transcriptional coactivators of the Hippo pathway network and regulate cell proliferation, migration, and apoptosis. Inactivation of the Hippo signaling pathway promotes YAP / TAZ entry into the nucleus, where they interact with transcriptional enhancer-associated domain (TEAD) transcription factors, coactivating target gene expression and promoting cell proliferation. TEAD regulates target genes such as connective tissue growth factor (CTGF), Cyr61, AXL receptor tyrosine kinase, and MYC, which are closely related to tumorigenesis. TEAD has also been shown to be overexpressed in breast cancer stem cells, breast cancer, ovarian cancer, phagocytic tumors, renal cell carcinoma, medulloblastoma, and gastric cancer. Hyperactivation of YAP and TAZ and / or mutations in one or more members of the Hippo pathway network are associated with many cancers.Recent studies have also reported that resistance to the EGFR tyrosine kinase inhibitors Tarceva (erlotinib), Iressa (gefitinib), or Tagrisso (osimertinib) is associated with YAP overexpression or amplification, along with epithelial-mesenchymal transition (EMT) phenotype changes.
[0003] The present inventors have completed the present invention by developing novel heterobicyclic compounds for inhibiting YAP-TEAD protein interaction. [Prior art documents] [Patent documents]

The reaction mixture is stirred overnight at room temperature. After confirming the completion of the reaction, the mixture is cooled to room temperature, water is added, and the mixture is extracted with ethyl acetate. The organic layer is dried over anhydrous sodium sulfate, filtered under reduced pressure, and the filtered organic layer is concentrated under reduced pressure.

[0084] [Stage-6] E (1 equivalent, reference equivalent) obtained in [Step-5] is dissolved in dimethylformamide, N-bromosuccinimide (1 equivalent) is slowly added dropwise, and the reaction mixture is stirred at room temperature. After confirming the completion of the reaction, water is added and the mixture is extracted with ethyl acetate. The organic layer is dried over anhydrous sodium sulfate and then filtered under reduced pressure. The filtered organic layer is concentrated under reduced pressure. The resulting residue is purified by MPLC to obtain the target compound F.
[0085] [Stage-7] The F (1 equivalent, reference equivalent) obtained in [Step 6] is subjected to a Stille or Suzuki coupling reaction with the corresponding A-stannane derivative and A-borane derivative (2 equivalents).

This assay uses MCF7 cells (BPS Bioscience, Inc., USA) transfected with a firefly luciferase reporter gene at the specific TEAD binding site, GTIIC (5'-ACATTCCA-3'). The luciferase luminescence expressed upon TEAD binding to target genes and activating transcription was measured to determine the transcriptional activity of TEAD. The cell lines were cultured in MEM medium supplemented with 10% FBS, 1% penicillin / streptomycin, 1% non-essential amino acids, 10 μg / ml insulin, and 400 μg / ml geneticin. Geneticin was omitted during the TEAD reporter activity inhibition test. 4x10 4 The cells were dispensed into a white 96-well plate at 100 μl / well and cultured for 6 hours. 50 μl of experimental compounds diluted to 3X concentration were added to each well. After 24 hours of culture, luciferase signals were measured by luminescence using the ONE-Glo luciferase assay system (Promega, E6120) according to the manufacturer's protocol. The 50% inhibition value (IC) of TEAD transcriptional activity was calculated. 50) was calculated using GraphPad Prism 9.
