Description

[0001] FUSED HETEROCYCLIC COMPOUNDS AND THEIR DERIVATIVES AS p300 SELECTIVE DEGRADERS

[0002] The present application claims priority to and the benefit of Indian provisional patent application No. 202441102777, filed on 24thDecember 2024, the contents of which are hereby incorporated by reference in its entirety.

[0003] TECHNICAL FIELD

[0004] The present disclosure is directed to compounds of formula (I), a pharmaceutically acceptable salt thereof, a solvate thereof or an isomer thereof as degraders of target proteins. Particularly, the present disclosure provides a compound of formula (I) useful for treating or preventing a disease or disorder responsive to the degradation of target proteins, preferably cancer, viral infection, autoimmune disease or disorder, inflammatory disease or disorder, neurodegenerative disease and metabolic disorder.

[0005] BACKGROUND EP300 (or p300) acts as histone acetyltransferase (HAT) and transcriptional adapter, thereby regulates transcription via chromatin remodelling and co-activator (Delvecchio et al., Nat Struct Mol Biol. 2013 Sep;20(9): 1040-6). Both histone and non-histone proteins are acetylated by p300. In addition to HAT function, p300 has crotonyl -transferase activities, and that p300-catalyzed histone crotonylation directly stimulates transcription to a greater degree (Sabari et al.. Mol Cell. 2015 Apr 16;58(2):203-l). EP300 functions by scaffolding or as coactivator and enhancer of different transcription factors like HIFla, BRCA-1, p53, NFKB, C-Myc, PD-L1, Estrogen receptor (ER) and Androgen receptor (AR) (Pao et al. PNAS USA.

[0006] 2000, 97, 1020).

[0007] Conventional CBP / p300 inhibitors do not discriminate between CBP and p300 proteins due to high homology. They show lesser than desirable efficacy in various cancer models within very well tolerated doses. A synthetic lethal relationship between these paralogs in cancer set up has been well established recently. Paralog targeting approach in recent time has been proved to be possible with degrader approach due to differentiated ternary complex formation. CBP mutation frequency is reported to be higher in several solid and hematological malignancies, for example, 10% to 15% of non-small cell and small cell lung cancers harbor loss-of-function aberrations in the CBP gene (Kishimoto et al. Clin Cancer Res 2005, 11: 512 - 9; George et al. Nature 2015, 524:47 - 53). Targeting wild type paralogue, p300, by itsselective degradation is expected to enhance efficacy in CBP-mutant or p300-dependent malignancies (Ogiwara et al., Ca Discov 2016). In prostate cancer, p300 plays a major role for androgen-dependent and -independent transactivation of the AR (Gong et al., Oncogene 2006: 2011-21). Neuroblastoma cancer cells primarily depend on p300, not CBP, for their survival by regulating enhancer acetylation by interacting with TFAP2β, a transcription factor member of the lineage-defining transcriptional core regulatory circuitry (CRC) of neuroblastoma (Durbin et al., Ca Disc 2021). By considering the above facts, p300 depletion will have a therapeutic advantage in PTEN-deficient, AR+ prostate, ER+ breast cancers and MYCN-amplified neuroblastoma, and also in the indications which are approved for immune checkpoint blockers (ICB) by governing the acetylation of PD-L1 directly (nuclear localization) and transcription of PD-L1 (histone acetylation at the promoter level) (Gao et al., Nat Cel Bio 2020; Pardoll and Drake J. Exp. Med. 2012).

[0008] Selective degraders of p300 are expected to enhance efficacy of SOC drugs or immune checkpoint blockers by governing the acetylation and transcription of oncogenic factors and co-stimulatory molecules involved in tumour progression.

[0009] Therefore, selective degradation of p300 activity provides a promising route to the treatment of certain cancers. Accordingly, compounds that can degrade the activity of p300 are of interest in cancer therapy.

[1154] BIOLOGICAL ASSAY

[1155] Targeted protein degradation controls the amount of a harmful cellular protein rather than modulation or inhibition of its function. This novel therapeutic approach also offers many opportunities to differentiate from inhibitor-based therapies. First, by catalysing the destruction of their target protein, degrader molecules may also disrupt scaffolding functions of proteins otherwise not addressed by small molecule inhibitors, allowing for drug properties that are unlike other classes of drugs. Second, degraders may offer higher potency and differentiated cellular pharmacology. Unlike inhibitors, which must remain bound to a single target protein,degrader molecules can catalyse the ubiquitination and destruction of multiple copies of the same protein since the degraders themselves are not degraded in the proteasome.

[1156] There are various technologies now currently available to directly measure the degradation of target proteins induced by PROTACs, for example Western Blot and Capillary Electrophoresis Immunoassays, High-Throughput Flow Cytometry and In-Cell Western, AlphaLISA SureFire Technology, Time-Resolved Fluorescence Energy Transfer-Based Assays or Nano-Gio HiBiT Technology.

[1157] Determination of Degradation of Protein in HiBiT Assay:

[1158] U2OS-HiBiT Assay Protocol:

[1159] U2OS-p300 HiBiT cells were seeded and incubated overnight at 37°C in a CO2 incubator for adherence. Next day, both the cells were pretreated with various concentrations of degrader for 24 hrs in the incubator. Working HiBiT-lytic reagent was added to the cells and incubated on orbital shaker at room temperature for 20 mins. Post incubation, the chemiluminescent signal was read using a luminometer. Selected compounds of the present disclosure were screened in the above-mentioned assay procedure and the percentage of p300 degradation in HiBiT assay at 0.2pM were determined.

[1160] Exemplary compounds of the present disclosure were screened by the above-mentioned assay. For certain exemplary compounds of the present disclosure, the % p300 degradation @0.2pM is given in the below Table-F.
