Abstract
Description
Technical Field
[0001] The present invention relates to the field of medicines, and in particular to an ectonucleotide pyrophosphatase / phosphodiesterase 1 inhibitor and a preparation method and use thereof. Background Art
[0002] Cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) activates the stimulator of interferon genes (STING) pathway, which is an important anti-cancer innate immune pathway. The cGAS-cGAMP-STING pathway can be activated by cytoplasmic DNA under microbial infection or pathophysiological conditions including cancer and autoimmune diseases. Cyclic GMP-AMP synthase (cGAS) belongs to the nucleotidyl transferase family and is an important cytoplasmic DNA sensor in the innate immune pathway. It is activated after binding to cytoplasmic dsDNA and catalyzes GMP and AMP to produce the signaling molecule (2'-5', 3'-5') cyclic GMP-AMP (or 2',3'-cGAMP or cGAMP). 2',3'-cGAMP acts as a second messenger during microbial infection, binds to and activates STING on the endoplasmic reticulum membrane, thereby inducing the production of type I interferon (IFN) and inflammatory cytokines, regulating downstream protein expression, inducing cell growth arrest and apoptosis, and producing anti-infective effects. In addition to its role in microbial infection, the STING pathway can also regulate the innate immune recognition of immunogenic tumors through cGAMP and type I interferon, enhance anti-tumor immune responses, and thus inhibit the occurrence and development of cancer. The STING pathway has become a therapeutic target for tumors and autoimmune diseases.
[0003] cGAMP is a key stimulator of the innate immune response and an endogenous activator of STING, which has anti-tumor immune effects. Ectonucleotide pyrophosphatase / phosphodiesterase 1 (ENPP1) is the main hydrolase that degrades cGAMP. ENPP1 is a member of the ectonucleotide pyrophosphatase / phosphodiesterase (ENPP) family and is a type II transmembrane glycoprotein containing two identical disulfide-bonded subunits. ENPP1 protein has a wide range of specificity and can cut a variety of substrates including phosphodiester bonds of nucleotides and nucleotide sugars and pyrophosphate bonds of nucleotides and nucleotide sugars. ENPP1 can hydrolyze nucleoside 5' triphosphates into their corresponding monophosphates, and can also hydrolyze polyphosphate diadenosine. cGAMP produced by tumor cells is rapidly hydrolyzed by ENPP1 after being transported to the extracellular space, producing immunosuppressive adenosine molecules, thereby promoting tumor immune escape. Inhibiting ENPP1 activity to increase cGAMP levels in the tumor microenvironment has become a potential strategy for tumor immunotherapy.
[0004] Since the function of ENPP1 as a regulator of the cGAS-STING pathway was confirmed, some research has been conducted on ENPP1 selective inhibitors, but the development of ENPP1 inhibitors with drug-like properties faces great difficulties. Currently, no such drugs are on the market, and only a few molecules are undergoing early clinical and preclinical studies to study their role as immunomodulators in tumor immunotherapy. In 2022, the oral ENPP1 small molecule inhibitor RBS2418 entered Phase I clinical trials (NCT05270213) to be administered in combination with Keytruda or as a monotherapy for the treatment of advanced unresectable, recurrent or metastatic tumors. Unfortunately, its structure has not yet been made public, so its precise structural information is still unclear.
[0005] QS-1 is a PC-1 inhibitor developed by Pfizer (Bioorganic & Medicinal Chemistry Letters 2009, 19, 3339-3343). In 2020, researchers from Stanford University reported that the compound showed a strong affinity for ENPP1 (K i =1600 nM). Furthermore, researchers at Stanford developed a series of ENPP1 inhibitors containing phosphate groups, and its representative compound 1 showed a very high affinity for ENPP1 (K i <2nM), and the results of in vivo pharmacodynamic studies showed that compound 1 could inhibit the growth of breast cancer in E0771 mice.
[0006] However, under the test conditions of the present invention, compound 1, despite its IC 50 The inhibitory IC of ENPP1 in MDA-MB-231 breast cancer cells was 0.6 nM. 50 The activity of this compound is 50nM, which is more than 80 times lower. In addition, this type of compound has a cell membrane-impermeable phosphate group. The effective dose of this compound in the in vivo efficacy test is as high as 300mg / kg, and it can only be administered subcutaneously, which seriously limits the further development of this type of drug as a candidate new drug.
