Definitions
- the present invention relates to the salt form of pyrrolotriazine compound, its crystal form, its preparation method and application. It specifically relates to the compound of formula (II) and its crystal form.
- MNK Mitogen-activated protein kinase interacting kinase
- MNK1a Mitogen-activated protein kinase interacting kinase
- MNK2b Mitogen-activated protein kinase interacting kinase
- the four subtypes all contain a nuclear localization signal (NLS) sequence at the N-terminus and a sequence that binds to eIF4G, so that it can enter the nucleus to play a role, and recognize and bind to the downstream eIF4E.
- NLS nuclear localization signal
- MNK1a and MNK2a subtypes have binding sites for MAPK and can be activated by upstream ERK and p38 phosphorylation.
- the nuclear export signal (NES) at the C-terminal of MNK1a allows it to be widely present in the cytoplasm, while most of the other three subtypes are present in the nucleus.
- Eukaryotic initiation factor 4E is a cap-binding protein that can specifically recognize the cap structure at the 5' end of mRNA and is an important initiation factor for protein translation.
- S209 phosphorylated eIF4E can promote the translation process of downstream proteins, mainly including c-MYC, cyclin D1, VEGF, FGF and anti-apoptotic proteins such as mcl-1 and Bcl-2.
- the expression of eIF4E is up-regulated in various malignant tumors such as lung cancer, colorectal cancer, gastric cancer, and pancreatic ductal carcinoma.
- MNK is the only kinase known to phosphorylate eIF4E.
- MNK is at the intersection of multiple pathways involved in tumor and immune signaling, such as RAS and T cell receptor (TCR), which can selectively control the transcription of regulators of antitumor immune response.
- MNK activity and activation of eIF4E are critical for tumorigenesis and progression, but not necessary for normal cells. Therefore, selective MNK inhibitors are expected to become antitumor drugs with low toxicity.
- EFT508 (WO2015/200481; WO2016/172010; WO2017/075394; WO2017/075412; WO2017/087808; WO2017/117052; WO2018/152117; WO2018/218038) is a selective oral inhibitor developed by EFFECTOR THERAPEUTICS, INC. .
- eFT508 can selectively inhibit the expression of PD-1, LAG3, and IL-10, and improve the function of cytotoxic T cells, while the proliferation of normal T cells is not affected.
- Preclinical studies have found that the combination of eFT508 and PD-1 monoclonal antibody can enhance drug efficacy and improve response rate. Phase I clinical trials have been completed, and the safety is good.
- the monotherapy for hematological tumors and trending prostate cancer is in clinical phase II research, and it is used in combination with Avelumab monoclonal antibody for microsatellite stable colorectal cancer (MSS CRC) ) is in phase II clinical research, and it is used in combination with PD-1/PD-L1 therapy (for patients with disease progression or no complete or partial response to single PD-1/PD-L1 therapy) for solid tumors
- MSS CRC microsatellite stable colorectal cancer
