Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medicine, and particularly relates to a NAMPT inhibitor, a composition, a preparation method and use. BACKGROUND

[0002] Gastric cancer is a common digestive system malignant tumor in the world. Although with the continuous development of surgical, radiotherapy and immunotherapy and other treatment methods, the diagnosis and treatment of gastric cancer have been improved compared with the past, the five-year survival rate of patients is still about 25%-35%, and the five-year survival rate of advanced gastric cancer is only about 6%. Traditional chemotherapeutic drugs are the main treatment drugs for advanced gastric cancer, including platinum drugs (oxaliplatin, cisplatin), fluorouracil drugs (fluorouracil, capecitabine), paclitaxel and irinotecan, but these drugs are all cytotoxic drugs, lack of selectivity, and have various adverse reactions, especially in the process of combined drug use, there is still a big development bottleneck in the treatment of gastric cancer. With the development of gene sequencing technology, precise treatment has become an important idea for the treatment of gastric cancer, and according to the molecular typing of patients, corresponding targeted drugs are selected for individualized treatment of patients, which has become an inevitable trend of targeted treatment of gastric cancer. In recent decades, some targeted drugs (ramucirumab and apatinib, etc.) have also been developed for the treatment of gastric cancer, although they have achieved success in the treatment of gastric cancer, but for many patients who do not express or lowly express these target points, there is still a lack of effective targeted treatment means. It can be seen that the research and development of gastric cancer related treatment targets and drugs are of great significance to the comprehensive treatment of gastric cancer, and the development of new anti-gastric cancer targeted drugs is imminent.

[0003] Metabolic reprogramming is one of the hallmark features of cancer, and the most prominent feature in tumor metabolism is abnormal energy metabolism. Nicotinamide adenine dinucleotide (NAD + ) is a coenzyme for redox reactions, which mediates redox reactions in various metabolic pathways, including glycolysis, and is the core of energy metabolism. NAD + also affects many key cellular functions, including metabolic pathways, DNA repair, chromatin remodeling, cell aging and immune cell function. Nicotinamide phosphoribosyltransferase (NAMPT) is a key rate-limiting enzyme in the NAD + salvage pathway, and targeting NAMPT can lead to depletion of NAD + , inhibit ATP synthesis, and further regulate tumor cell metabolism and NAD +Synthetic capacity. A large number of studies have found that NAMPT is overexpressed in colorectal cancer, prostate cancer, breast cancer, gastric cancer and acute myeloid leukemia 17 and other human malignancies, and is related to the occurrence and prognosis of tumors. NAMPT is highly expressed in tumor transformation to compensate for increased metabolic demand, and overexpression of NAMPT can increase tumor cell proliferation, colony formation and resistance to apoptosis. Recent studies have revealed other roles of NAMPT in cancer biology, including DNA repair mechanisms, cross-talk with oncogenic signaling pathways, cancer cell stemness, and immune response. In addition, studies have shown that NAMPT inhibitor FK866 can inhibit gastric cancer cell proliferation and induce apoptosis to increase the chemosensitivity of gastric cancer cells to fluorouracil. NAMPT has become a promising target for cancer treatment. Currently, five NAMPT inhibitors FK866, CHS828, CB30865, GMX177 and KPT-9274 have entered clinical studies. Three of them were terminated due to their toxic side effects, and so far no NAMPT inhibitor has been approved for marketing. Because NAD + NAMPT inhibitors exhibit effects in targeting cancer cells while also having significant toxic effects on normal cells. Therefore, how to reduce toxicity is the biggest challenge faced by NAMPT inhibitor development.

[0004] NAMPT has a synthetic lethal relationship with the key enzyme nicotinic acid phosphoribosyltransferase (NAPRT) in the Press-Handler pathway, and the strategy of combining NAMPT with nicotinic acid based on the concept of synthetic lethality reduces the toxic side effects. Other studies have shown that NAMPT inhibitors exhibit significantly higher efficacy in cancer cells that lack NAPRT expression and are completely dependent on NAMPT for NAD + synthesis. SUMMARY

[0203] Determination of cell growth inhibition rate by MTT method

[0204] Test method: Seven strains of gastric cancer cells (HGC-27, MKN-28, MKN-45, AGS, SGC-7901, NCI-N86, HS746T) and two strains of normal cells (GES-1, WI-38) were respectively placed in a cell culture box at 37℃, 5% CO2, using RPMI-1640 medium containing 10% fetal bovine serum or DMEM medium. When the cells were in the logarithmic phase, 5000-8000 cells per well were inoculated in a 96-well plate, and after 24h of culture, the old culture medium was removed and the culture medium containing the sample to be tested (100mmol / L target compound DMSO stock solution was prepared into experimental concentrations of 100, 50, 25, 12.5, 6.25μmol / L) was added, and three replicate wells were set for each experimental concentration, and a blank control group was also set.

[0205] After 72h of experimental cell culture, 10μL of MTT solution was added, and after 4h of incubation, the supernatant in the 96-well plate was aspirated, 150μL of DMSO was added to each well, and shaken for 20min. The absorbance value (OD value) of each well of the 96-well plate in the experiment was measured at 570nm using an enzyme-labeled instrument, the cell proliferation inhibition rate (IR) was calculated, the cell proliferation inhibition rate % = (control well average OD value - experimental well average OD value) / (control well average OD value - blank OD value), and the half-inhibitory concentration IC50 value (means ± SD, n = 3) was calculated using SPSS 20.0, and the specific data are shown in Table 1 (the above parallel experiments were independently repeated three times).

[0206] Test results: The above test results show that the compound of the present application or its pharmaceutically acceptable salt has inhibitory activity on seven strains of gastric cancer cells (HGC-27, MKN-28, MKN-45, AGS, SGC-7901, NCI-N86, HS746T), and has no proliferation inhibitory activity on two strains of normal cells (GES-1, WI-38).

[0216] For example, compound NHWL024068 was used to perform flow cytometry-cycle experiment to measure the ability of compound NHWL024068 to induce S and G2 / M phase arrest of gastric cancer cells (the experimental results are shown in Figure 1 ), the ability to induce apoptosis of gastric cancer cells (the experimental results are shown in Figure 2 ), and it can be seen that its induction ability is outstanding.

[0217] For example, compound NHWL024068 was used to perform mitochondrial damage experiment, and the experimental results are shown in Figure 3 , and it can be seen that its ability to induce loss of mitochondrial membrane potential of gastric cancer cells is significantly stronger than Apatinib.

[0218] For example, compound NHWL024068 was used to perform Transwell migration experiment, and the experimental results are shown in Figure 4 , and it can be seen that its ability to inhibit gastric cancer cell migration is significantly stronger than Apatinib.

[0219] For example, compound NHWL024068 was used to perform monoclonal formation experiment, and the experimental results are shown in Figure 5 , and it can be seen that its ability to resist monoclonal formation is significantly stronger than Apatinib.

[0220] For example, compound NHWL024068 was used to perform EDU anti-proliferation experiment, and the experimental results are shown in Figure 6 (50μm, 20x), and it can be seen that its anti-proliferation ability is comparable to Apatinib.
