Nicotinamide adenine dinucleotide (NAD+) as an enzyme cofactor for transferring hydrogen participates in various physiological functions such as energy synthesis, cellular metabolism, DNA repair, etc[1]. As an important small-molecule metabolite, nicotinamide adenine dinucleotide (NAD+) is widely involved in a series of biochemical reactions in cell energy metabolism, such as glycolysis, oxidative phosphorylation, and fatty acid oxidation. Therefore, NAD+ is crucial for human health[2].
There are three biosynthetic pathways for NAD+[3]:
1. De novo pathway. This pathway starts with indoleamine 2,3-dioxygenase (IDO) or tryptophan 2,3-dioxygenase (TDO), which catalyze the conversion of tryptophan into N-formylkynurenine. Then, N-formylkynurenine is converted by formamidase (KFase) to kynurenine which is then hydroxylated by kynurenine 3-hydroxylase (K3H) to produce 3-hydroxykynurenine. The product 3-hydroxykynurenine is further converted into 3-hydroxyanthranilic acid which is then converted into 2-amino-3-carboxymuconate-6-semialdehyde (ACMS) by kynureninase (Kyase) and 3-hydroxyanthranilate 3,4-dioxygenase[4]. ACMS then cyclizes to form quinolinic acid (QA) that participates in NAMN biosynthesis with quinolinate phosphoribosyltransferase (QPRT)[5,6].
2. Preiss-Handler pathway. This pathway starts with the conversion of nicotinic acid (NA) to nicotinamide mononucleotide (NAMN) by Nicotinate Phosphoribosyltransferase (NAPRT)[7]. NAMN is then used for the biosynthesis of nicotinic acid adenine dinucleotide (NAAD) by nicotinamide/nicotinic acid mononucleotide adenylyltransferase (NMNAT). Finally, NAD+ synthase (NADS) transforms the NAAD into NAD+ with ammonia and ATP action[8-9].
3. Salvage pathway. Rather than generated de novo pathway, most NAD+ is recycled from NAM, NA, NR and NMN in the salvage pathway to maintain the cellular NAD+ levels. Rather than generated de novo pathway, most NAD+ is recycled from NAM, NA, NR and NMN in the salvage pathway to maintain the cellular NAD+ levels. Therefore, the salvage pathway is the primary source of NAD+ in mammalian cells. NAM could be recycled from NAD+ consumption reactions, including both NAD+-dependent deacylation and ADP-ribosylation, into NMN by NAMPT, which catalyzes the rate-limiting reaction in the salvage pathway[10]. The precursor NR is transformed to NMN by NRK1/2. Ultimately, NMN is adenylated by NMNAT to yield NAD+[2].
Nicotinamide phosphoribosyltransferase (NAMPT) is the rate-limiting enzyme that catalyzes the synthesis of nicotinamide adenine dinucleotide (NAD+).
Cancer cells have different metabolic demands and increased NAD+ turnover as compared to normal cells[11]. Therefore, the salvage pathway is of major importance to cancer cells. In fact, many types of cancer cells have been shown to highly express NAMPT, reflecting potentially increased dependence on this pathway due to high NAD+ utilization and in some cases, loss of expression of other key NAD+ biosynthetic enzymes[12-15]. The types of cancers reported to have high NAMPT expression include, but are not limited to, colorectal cancer (CRC), breast cancer, osteosarcoma, chondrosarcoma, pancreatic ductal adenocarcinoma, oral squamous cell carcinoma, prostate cancer, rhabdomyosarcoma, leiomyosarcoma, esophagogastric junction adenocarcinomas, thyroid cancer, leukemia, lymphoma, ovarian cancer, and some renal cancer, and in many of these, higher NAMPT expression correlated with worse outcomes[16-32]. NMN may also be produced from nicotinamide riboside via nicotinamide riboside kinase[13]. Currently, however, NAMPT is the only NAD+ production enzyme that has been targeted in the clinic.
NAMPT exists in two forms in mammals: intracellular NAMPT (iNAMPT) in the cytoplasm and nucleus and extracellular NAMPT (eNAMPT) in the plasma or extracellular space.
NAMPT is overexpressed in several human malignancies such as colorectal cancer, ovarian cancer, breast cancer, gastric cancer, prostate cancer, endometrial cancer, melanoma, multiple myeloma, astrocytoma, liver cancer, thyroid cancer, malignant lymphoma, and others. Given its role in promoting various aspects of the malignant phenotype, inhibiting NAMPT may have anticancer effects. NAMPT inhibition also leads to ATP depletion, reduced PARP-1 and SirT1 activity, and ultimately cell death[34-36]. Tumor cells are more sensitive to iNAMPT inhibition than normal cells due to increased NAD+ and ATP catabolism[37]. The highly specific NAMPT inhibitor FK866 can induce apoptosis in human hepatocellular carcinoma cells (HepG2) by depleting NAD+, which could be partially reversed by adding NAM or nicotinic acid[33]. NAMPT inhibitors have potential therapeutic applications in treating triple-negative breast cancer, liver cancer, gastric cancer, non-small cell lung cancer with epidermal growth factor receptor gene mutations, glioblastoma, melanoma, etc.
eNAMPT can be released by various types of cells and acts as a cytokine on multiple cell types. It is able to activate downstream intracellular pathways by stimulating the subsequent release of other cytokines.
Plasma eNAMPT levels are elevated in various human malignancies, including astrocytoma, myeloma, male oral squamous cell carcinoma, gastric cancer, endometrial cancer, hepatocellular carcinoma, colorectal cancer, and invasive breast cancer, etc[38-46]. In astrocytoma, plasma eNAMPT levels increase with tumor staging and are considered a prognostic marker. Similarly, eNAMPT levels are elevated in tumor later stages of male oral squamous cell carcinoma, hepatocellular carcinoma, endometrial cancer, and infiltrating breast cancer. In patients with endometrial cancer, higher eNAMPT levels are associated with endometrial infiltrating and shorter patient survival. Higher eNAMPT levels in infiltrating breast cancer are associated with lymph node metastasis and the loss of estrogen and progesterone receptors. Myocardial cells treated with H2O2 or incubated in the condition of serum starvation will secrete eNAMPT[47]. Pretreatment of human chondrocytes with eNAMPT may inhibit IGF-1-stimulated proteoglycan synthesis and AKT and insulin receptor substrate-1 phosphorylation while activating ERK[48]. Researchers have found that eNAMPT treatment rapidly induces the production of IL-6 in mouse macrophages, followed by IL-6-mediated STAT3 activation. Interestingly, IL-1β, TNF-α, and IL-6 can induce the expression of eNAMPT in macrophages[49-51]. These data suggest that plasma eNAMPT may contribute to carcinogenesis and tumor growth.
NAMPT is also closely related to the occurrence and development of various diseases.
Diabetic nephropathy is one of the most severe diabetic microvascular complications and a risk factor for death in diabetes patients, posing a serious threat to human health. The pathogenesis of diabetic nephropathy is complex and diverse, mainly involving renal inflammation and fibrosis. Studies have found that the renal inflammatory and fibrotic process is closely related to NAMPT. On the one hand, in glomerular mesangial cells, NAMPT can promote the expression and translocation of GLUT-1 to the cell membrane, thereby mediating intracellular glucose transport, leading to increased glucose metabolism and extracellular matrix synthesis, which causes renal parenchymal damage[52,53]. On the other hand, diabetic patients are in an obvious imbalance state of oxidative stress. By detecting the patient's serum, it is found that serum levels of NAMPT are directly proportional to lipid peroxidation metabolite levels and inversely proportional to antioxidant enzyme SOD levels, indicating a close relationship between NAMPT and oxidative stress in vivo[54]. The interaction of these two factors together promotes the occurrence of diabetic nephropathy.
NAMPT is closely related to the occurrence and development of cardiovascular and cerebrovascular diseases. NAMPT expression is significantly increased in carotid plaques of patients with unstable coronary atherosclerosis and ruptured plaques in patients with acute myocardial infarction[55,56]. Studies have found that NAMPT can enhance the enzymatic activity of MMP-2 and MMP-9, while MMP can degrade the extracellular matrix, which leads to a thin fibrous cap and plaque rupture, suggesting that NAMPT plays an important role in the instability of atherosclerotic plaques[57]. NAMPT inhibitors can reduce myocardial infarction size, neutrophil infiltration, and the production of reactive oxygen species generation within a mouse model of myocardial ischemia-reperfusion injury[58]. Therefore, as an effective therapeutic drug, NAMPT pharmacological inhibitors can reduce oxidative stress-mediated tissue damage in myocardial infarction.
NAMPT is overexpressed in placental tissue from women with gestational hypertension, and the expression levels of both are significantly positively correlated, suggesting a close relationship with gestational hypertension.
Clinical studies have shown that the concentration of NAMPT is significantly increased in chronic inflammatory diseases. As a pro-inflammatory adipokine, NAMPT promotes the expression of monocyte chemoattractant protein-1 and intercellular adhesion molecule-1 protein[59]. NAMPT can induce CD14+ monocytes to produce inflammatory cytokines such as interleukin-1β, tumor necrosis factor-α, and interleukin-6, and increase the surface expression of co-stimulatory molecules CD54, CD40, and CD80[60]. eNAMPT can activate NF-κB, leading to upregulation of inducible nitric oxide synthase expression and promotion of inflammatory responses[61].
NAMPT also plays a role as an immune regulatory cytokine. The development and function of T lymphocytes and B lymphocytes are almost completely dependent on NAMPT. Conditional knockout of the NAMPT gene in lymphocytes leads to a significant decrease in thymocyte numbers and almost complete loss of peripheral blood T lymphocytes and B lymphocytes[62]. High levels of NAMPT can be detected in the serum of patients with autoimmune diseases such as rheumatoid arthritis and autoimmune encephalitis[63,64].
The high expression of NAMPT in blood and gastric adipose tissue is positively correlated with overweight or obesity. NAMPT is a necessary factor for overweight or obesity, and downregulating NAMPT in adipose tissue can help alleviate obesity[65].
Currently, the NAMPT inhibitor FK866 is in the clinical stage. It can exert antitumor effects in cell models and animal models, especially in hematological tumors. FK866 can clear tumor cells to undetectable levels, resulting in long-term survival of 80% of mice[66]. However, there are some issues with FK866. Clinical trial results have shown that FK866 treatment can cause dose-limiting toxicities such as thrombocytopenia, as well as gastrointestinal reactions such as diarrhea and constipation[67]. This is also the reason why the phase II clinical trial utilizing FK866 was halted. In addition, NAMPT exists in both enzymatically active and inactive forms. FK866, as an enzyme inhibitor, cannot inhibit the non-enzymatically active form of NAMPT (eNAMPT) in plasma and extracellular spaces. eNAMPT has been shown to contribute to carcinogenesis and tumor growth, which may affect the therapeutic effect of FK866. Therefore, there is a need to improve existing inhibitors or develop new drugs to overcome the deficiencies of existing inhibitors.
Designing degraders targeting specific proteins is a new model for drug development. We utilize the Proteolysis Targeting Drug (PROTAD) technology platform for the development of antitumor drugs. PROTAD can label target proteins for degradation through specially designed bispecific protein regulators, and degrade target proteins by activating intracellular protein degradation pathways. Therefore, we hope to develop protein modulators that can degrade disease-related pathogenic proteins using the protein degradation technology platform, thereby treating cancer patients and prolonging their survival.
Therefore, there is an urgent need for a series of novel protein degraders designed based on NAMPT target protein for the treatment and/or prevention of diseases or disorders associated with NAMPT.

After 24 h, the inoculated cells were treated with the compounds of the present disclosure which were serially diluted. After the cells were treated with the compounds of the present disclosure for 72 h, the CellTiter-Glo® reagent was added to the culture medium for cell viability assessment according to the instructions provided with the kit. DMSO served as the negative control, and FK866 inhibitor was used as the positive control, both treated with the same protocol as the compounds of the present disclosure. The growth inhibition of the compounds of the present disclosure on cells was plotted by Prism Graphpad software, and the IC50 values of the compounds of the present disclosure were calculated therefrom. Results were shown in Table 2.
The results indicate that the compounds of the present invention (including the compounds in Table 1 and compounds of the examples 1-91) can inhibit the proliferation of tumor cells (as shown in Table 2). The IC50 of some example compounds are comparable to, or even superior to, the positive control FK866. For example, the IC50 of SIAIS630010 is 0.3506 nM. This indicates that the compounds of the present invention have a comparable, or even superior, inhibitory effect on tumor cell growth compared to the positive control FK866.
MOLT4 and HL60 tumor cells were seeded separately in 12-well plates containing 1 mL of RPMI1640 medium, with a cell seeding density of 0.5×106 cells/mL. On the second day, the parent inhibitor FK866 and the compounds SIAIS630120 and SIAIS630121 of the present disclosure were individually dissolved in DMSO to obtain stock solutions of the respective compounds at a concentration of 10 μM. Subsequently, 1 μL of the 10 μM compound stock solution was added to 1 mL of cell culture medium to achieve a final concentration of 10 nM. The cells were treated continuously for 4 days, and cell viability was measured once daily during this period. Specifically, cells were sampled once a day, adjusted to a concentration of 1×106/mL using a cell staining buffer, stained with 4′,6-diamidino-2-phenylindole dihydrochloride (DAPI) (1:250), and then analyzed with a flow cytometer. Initially, the cells were gated based on differences in cell size, followed by DAPI staining to gate for dead cells. Finally, the cytotoxic efficiency was assessed by calculating the DAPI-positive ratio.
The results of the in vitro cytotoxicity experiment were shown in
Tumor cells were seeded at a specific cell density in a 6-well plate containing 2 mL of RPMI1640/DMEM medium. For SW620, HT29, MCF-7, and BEL7404 cells, the seeding density was 1×106 cells per well, respectively; for MOLT4, Jurkat, and HL60 cells, the seeding density was 0.5×106 cells/mL. The disclosed compounds (including those listed in Table 1 and Examples 1-91) were individually dissolved in DMSO to prepare stock solutions at concentrations of 1 μM, 5 μM, 10 μM, and 100 μM. On the second day, cells were treated with different concentrations of the compounds of the present disclosure (including those listed in Table 1 and Examples 1-91) for 24 hours (2 μL of different concentrations of compounds added to 2 mL of cell culture medium, resulting in final concentrations of 1 nM, 5 nM, 10 nM, and 100 nM). After 24 hours of compound treatment, the supernatant was removed, and cells were washed with PBS. The cells were then placed on ice and treated with protein lysis buffer containing protease and phosphatase inhibitors. The lysate was centrifuged at 12,000 RPM for 15 minutes at 4° C., and the supernatant was collected. Equal amounts of protein were mixed with 5×SDS, and after denaturation at 95° C. for 5 minutes, the samples were either frozen at −20° C. or subjected to direct protein electrophoresis. SDS-PAGE was performed using equal amounts of protein, and proteins were transferred to a nitrocellulose membrane at 95 V and 4° C. for 90 minutes. After membrane transfer, the membrane was blocked with TBST containing 5% skim milk powder (purchased from Beijing Cowin Bioscience Co., Ltd.) at room temperature for 1 hour. The membrane was then incubated with the primary antibody overnight at 4° C. After incubation with the primary antibody, the membrane was washed three times with TBST at room temperature for 5 minutes each. Subsequent steps, including the incubation with the secondary antibody (peroxidase-labeled goat anti-rabbit IgG (H+L)) and visualization, were performed according to the instructions provided by Jackson ImmunoResearch Laboratories Inc.
Determining Half-Maximal Degradation Concentration (DC50) value (the drug concentration required for degrading proteins by 50%, abbreviated as DC50) reads method: comparing the grayscale values of the Western blotting bands for the drug treatment with those of the Western blotting band f after treatment with blank DMSO. The DC50 is identified within the range of drug concentrations where the grayscale value matches half of the corresponding Western blotting band's grayscale value after treatment with blank DMSO.
Calculation of the DC50 values can be performed using ImageJ to read the grayscale values of Western blotting bands after drug treatment. A curve fitting the relationship between drug concentration and grayscale values is then generated to estimate the drug concentration corresponding to half of the grayscale value.
The present disclosure employed Western blot analysis to assess the expression levels of NAMPT protein in tumor cells treated with the compounds of the present disclosure (including those listed in Table 1 and Examples 1-91) for 24 hours. The Western blot results are illustrated in
