Description

Compounds containing tricyclic rings Technical Field

[0001] The present application relates to a compound containing a tricyclic ring, a preparation method thereof, a pharmaceutical composition containing the compound, and its use in treating related diseases (such as cancer). Background Art

[0002] G1 to S phase transition 1 (GSPT1) is a transcription factor that mediates the recognition of stop codons and promotes the release of transcribed peptide chains from ribosomes. In addition to its role in transcription termination, GSPT1 is also closely involved in various important cellular processes, such as cell cycle regulation, cytoskeleton formation, and apoptosis. GSPT1 is considered an oncogenic factor in various tumors and has become one of the most attractive potential anti-tumor targets. Furthermore, downregulating GSPT1 can also affect the expression of proteins such as AR and AR-V7.

[0003] The androgen receptor (AR) belongs to the steroid receptor family of the nuclear receptor superfamily. Upon binding to androgens (such as testosterone and dihydrotestosterone), AR is released from the heat shock protein complex, undergoes phosphorylation, forms a dimer, and translocates to the cell nucleus, where it binds to its associated DNA fragments, thereby stimulating the transcription of its target genes. The transcriptional activity of the AR activated by ligand binding is coordinated by proteins called co-activators. AR antagonists primarily act by directly preventing testosterone or dihydrotestosterone from binding to the AR, blocking the effects of androgens on cells. This leads to anti-androgenic and anti-cell growth effects, ultimately inducing cell apoptosis, achieving a crucial role in the treatment of prostate cancer. Second-generation AR signaling inhibitors, abiraterone and enzalutamide, have achieved some success in clinical treatment, but resistance has emerged. The F876L mutation in the ligand binding region is a missense mutation that confers resistance to enzalutamide, converting it from an antagonist to an agonist. In addition, AR splicing mutants, especially AR-v7 mutations lacking the ligand binding region, are important mediators of second-generation drug resistance. The treatment of drug-resistant cancers remains a key challenge in cancer therapy. Current drug therapies induce drug resistance, with AR mutations (including point mutations and splicing mutations) being a key factor. Therefore, the development of new drugs to treat drug-resistant cancers is crucial.

[0004] PROTAC (proteolysis targeting chimera) molecules are a class of bifunctional compounds that can simultaneously bind to target proteins and E3 ubiquitin ligases. These compounds can induce the recognition of target proteins by the cell's proteasome, causing their degradation and effectively reducing their levels in cells. By introducing ligands that can bind to different target proteins into PROTAC molecules, PROTAC technology has become possible for the treatment of various diseases and has received widespread attention in recent years.

[0005] The applicant used PROTAC technology to develop a series of compounds with GSPT1 degradation / inhibition activity to treat related diseases.

A particular term should not be construed as undefined or unclear unless specifically defined, but rather should be understood according to its ordinary meaning in the art. When a trade name appears in this document, it is intended to refer to the corresponding commercial product or its active ingredient.

[0413] As used herein, "one or more" refers to an integer from one to ten. For example, "one or more" refers to one, two, three, four, five, six, seven, eight, nine, or ten; in some embodiments, the "one or more" is selected from one, two, three, four, five, or six. In some embodiments, the "one or more" is selected from one, two, or three. In some embodiments, the "one or more" is selected from one, or two.

[0414] Unless otherwise specified, It is used to indicate that the hydrogen atom at any position of the group in [] can be replaced by a group connected by "—", for example, by L.

[0415] The term "substituted" means that any one or more hydrogen atoms or lone pairs of electrons on a particular atom are replaced by a substituent, as long as the valence state of the particular atom is normal and the substituted compound is stable. When the substituent is an oxo group (i.e., =O), it means that two hydrogen atoms are replaced. Oxo groups do not occur on aromatic groups. For example, for It can be represented by one or more R 1 Substituent substituted, wherein the R 1 It can be substituted on ring B or on another ring, such as X on the ring 8 、X 9 、X 10 and its substituents, and -NH-.

[0416] The term "optionally" or "optionally" means that the event or situation described subsequently may or may not occur, and the description includes both the occurrence of the event or situation and the non-occurrence of the event or situation. "Optionally substituted" includes unsubstituted and substituted. For example, an ethyl group is "optionally" substituted with a halogen, meaning that the ethyl group may be unsubstituted (CH2CH3), monosubstituted (such as CH2CH2F), polysubstituted (such as CHFCH2F, CH2CHF2, etc.), or fully substituted (CF2CF3). It will be understood by those skilled in the art that for any group containing one or more substituents, no substitution or substitution pattern that is sterically impossible and / or cannot be synthesized will be introduced.

[0417] In this article, C m-n , means that the moiety has an integer number of carbon atoms in a given range. For example, "C 1-6 ” means that the group can have 1 carbon atom, 2 carbon atoms, 3 carbon atoms, 4 carbon atoms, 5 carbon atoms, or 6 carbon atoms.

[0418] When any variable (e.g., R) occurs more than once in a compound's composition or structure, its definition at each occurrence is independent. For example, if a group contains two R's, each R has an independent option.

[0419] When the number of a linking group is 0, such as -(CH2)0-, it means that the linking group is a covalent bond.

[0420] When one of the variables is selected from a covalent bond, it means that the two groups it connects are directly connected. For example, when L in ALZ represents a covalent bond, it means that the structure is actually AZ.

[0421] When a bond cross-links two atoms in a ring (including a monocyclic, fused, or spirocyclic ring), the bond can be bonded to any atom in the ring (including a monocyclic, fused, or spirocyclic ring). Indicates that the bonds on both sides can be connected to any two different atoms on ring A, ring B or ring C; for example Indicates that the bonds on both sides can be connected to any two different atoms on ring A, the middle benzene ring or ring C; further, for example It means that the bonds on both sides can be connected to any two different atoms in the four rings in the system.

[0893] The day of grouping is designated Day 0. Starting from Day 0 (d0), administer the drug once daily by gavage (dose 0.5-3 mpk). Tumor volume is measured 2-3 times per week, and mice are weighed and recorded. The general condition of the mice is observed and recorded daily. At the end of the experiment (e.g., Day 17), tumors are removed, weighed, and photographed.

[0894] The detection indicators and calculation formulas are as follows:

[0895] Tumor volume, TV (mm 3 )=1 / 2×(a×b 2 ), where a is the long diameter of the tumor and b is the short diameter of the tumor.

[0896] Relative tumor volume, RTV = TV t / TV0; TV0 is the tumor volume on day 0, TV t is the tumor volume at each measurement.

[0897] Relative tumor growth rate, T / C (%) = T RTV / C RTV ×100%; where T RTV RTV for the treatment group; C RTV The vehicle control group was RTV.

[0898] Tumor volume inhibition rate, TGI(TV) (%), TGI(%) = [1-(T-T0) / (C-C0)] × 100%; where T is the mean tumor volume of the treatment group; T0 is the mean tumor volume of the treatment group on day 0; C is the mean tumor volume of the control group; C0 is the mean tumor volume of the control group on day 0.

[0899] Tumor weight inhibition rate, TGI(TW)(%), TGI(%)=(1-TWt / TWc)×100%; wherein, TWt is the tumor weight of the treatment group; TWc is the tumor weight of the control group.

[0900] Body weight change rate, WCR (%) = (Wt t -Wt0) / Wt0×100%; where Wt0 is the weight of mice on day 0, Wt t= represents the weight of the mice at each measurement. Test results demonstrate that the compounds of the present application (e.g., Examples 41, 42, 73, and 74) exhibit tumor-suppressing activity in vivo. At a dose of 2 mpk, TGI (TW) ≥ 85% and TGI (TV) ≥ 95% on day 19. Furthermore, the weights of the mice in each dosing group remained relatively stable.
