Phthalazinone compound, preparation method and medical application thereof
Technical Field
The invention belongs to the field of innovative pharmaceutical chemistry, and in particular relates to a phenolphthalein ketone compound shown in a formula I or pharmaceutically acceptable salts, solvates, prodrugs, isomers or metabolites thereof, a preparation method, a pharmaceutical composition containing the compound, and application of the compound or the pharmaceutical composition in preparing antitumor drugs.
Background
Cancer is a serious disease which afflicts human health, and research and development of novel antitumor drugs are important subjects and long-term tasks in the field of biological medicine. Poly ADP-ribose polymerase, PARP, is a multifunctional protein post-translational modification enzyme that is widely found in eukaryotic cells. In mammalian cells, the PARP family has 17 members, whereas the members involved in DNA damage repair processes are only three of PARP1, PARP2, and PARP3, wherein PARP1 is a major member involved in DNA repair processes, when DNA damage is single-stranded broken, cells initiate DNA damage response procedures, PARP1 can sense DNA single-stranded damage gaps, and Nicotinamide Adenine Dinucleotide (NAD) is catalyzed by self-glycosylation of its zinc finger DNA binding domain located at the site of DNA damage + ) Decomposing into nicotinamide and ADP ribose, and using ADP ribose as substrate to make receptor protein and PARP1 form poly ADP-ribose polymer to form PARP-ADP ribose branched chain, avoiding recombination of DNA molecule around damaged part and damaged DNA, and simultaneously attracting DNA repair protein, histone H1, a series of transcription factors and other DNA repair enzymes such as X-ray repair cross complementary gene 1, DNA ligase 3, DNA guide polymerase beta and the like to be combined at the damaged part to repair the damaged part. When PARP function is impaired or inhibited, single strand breaks persist, which can easily lead to stalling of replication forks and DNA double strand breaks, and thus impaired DNA replicas appear and accumulate gradually, eventually leading to replication fork breakdown. In cells with normal functional homologous recombination repair pathways, the DNA double strand breaks are immediately repaired, which can compensate for the loss of function in the base excision repair pathway; however, in tumor cells lacking homologous recombination repair, such as breast cancer carrying BRCA1/2 mutations, there is a lack of compensatory mechanisms, and the tumor cells fail to repair DNA damage, ultimately leading to cell death.
Nicotinamide adenine dinucleotide (nicotinamide adenine dinucleotide, NAD for short) + ) Is an indispensable substance in the electron transfer process and plays an important role in the energy metabolism and signal transduction processes. In addition, NAD + NADH in the form of its reduced form is important for maintaining a reducing environment within the cell and thereby protecting the cell from oxidative stress. Thus, intracellular NAD + Is a critical factor in determining cell fate. Tumor cells have uncontrolled proliferation rates, rapid metabolic rates, and significantly increased oxidative stress levels relative to normal cells, and thus tumor cells are resistant to NAD + The change in level is sensitive. NAD (NAD) + Key enzymes of the in vivo biosynthetic pathway have become important targets for anticancer drugs. NAD (NAD) + In vivo synthetic pathwayIncluding de novo and salvage synthetic pathways.
NAD + The salvage synthesis route is to use nicotinic acid, nicotinamide or nicotinamide ribose as a starting material. Due to a plurality of NADs + Consumable enzymes such as poly (adenosine diphosphate) ribose polymerase (PARP) and deacetylase (Sirtuis, SIRT) can rapidly re-release nicotinamide, thereby NAD starting from nicotinamide + The salvage pathway is the most economical and dominant NAD + Biosynthetic pathways (gali U.S. et al J.Med. Chem.2013, 22, 56 (16): 6279-96). Whereas nicotinamide riboside transferase (nicotinamide phosphoribosyltransferase, NAMPT) controls nicotinamide to NAD + And (3) a speed-limiting enzyme for transformation. In view of the abnormal energy metabolism of tumor cells, NAD is more required + Rapid and timely supplementation, tumor cells are more dependent on NAMPT and are more sensitive to NAMPT inhibition. Therefore, NAMPT is considered as an effective anticancer target, and NAMPT inhibitors have become a hotspot for extensive research. Currently, two NAMPT inhibitors CHS-828 and FK866 have entered the clinical trial phase (Montecocco Fet al. Curr. Drug targets.2013,1, 14 (6): 637-43). However, the clinical trial results of these two compounds were not ideal and did not show significant therapeutic effect after administration to patients. Furthermore, these two compounds have poor pharmacokinetic properties and also show dose-dependent toxicity such as thrombocytopenia and gastrointestinal toxic side effects. Therefore, NAMPT inhibitors with novel structure and good pharmaceutical property are required to be further researched and developed.

Accordingly, the present invention includes metabolites of the compounds of the present invention, including compounds produced by a method of contacting a compound of the present invention with a mammal for a period of time sufficient to obtain the metabolites thereof.
The identification of metabolites is typically accomplished by preparing radiolabeled compounds of the invention (e.g., 14 c or 3 H) Isotope, parenteral administration thereof to an animal, such as a rat, mouse, guinea pig, monkey, or human, at a detectable dose (e.g., greater than about 0.5 mg/kg), allows forAllowing sufficient time for metabolism to occur (typically about 30 seconds to 30 hours) and for its conversion products to be isolated from urine, blood or other biological samples. These products are easy to isolate because they are labeled (others are isolated by using antibodies that are capable of binding to epitopes present in the metabolite). The metabolite structures are determined in a conventional manner, for example by MS, LC/MS or NMR analysis. In general, the analysis of metabolites is performed in the same manner as conventional drug metabolism studies known to those skilled in the art. So long as the metabolite products are not otherwise undetectable in vivo, they are useful in assays for therapeutic dosing of the compounds of the invention. The compounds of the present invention may contain non-natural proportions of atomic isotopes on one or more of the atoms comprising the compounds. For example, compounds can be labeled with radioisotopes, such as tritium @, for example 3 H) Iodine-125% 125 I) Or C-14% 14 C) A.
