Abstract
The bromodomain and extra-terminal domain (BET) proteins are epigenetic readers, regulating transcription via two highly homologous tandem bromodomains, BD1 and BD2. Clinical development of nonselective pan-BD BET inhibitors has been challenging, partly due to dose-limiting side effects such as thrombocytopenia. This has prompted the push for domain-selective BET inhibitors to achieve a more favorable therapeutic window. We report a structure-guided drug design campaign that led to the development of a potent BD1-selective BET inhibitor, 33 (XL-126), with a Kd of 8.9 nM and 185-fold BD1/BD2 selectivity. The high selectivity was first assayed by SPR, validated by a secondary time-resolved fluorescence energy transfer assay, and further corroborated by BROMOscan (∼57-373 fold selectivity). The cocrystal of 33 with BRD4 BD1 and BD2 demonstrates the source of selectivity: repulsion with His437 and lost binding with the leucine clamp. Notably, the BD1 selectivity of BET inhibitor 33 leads to both the preservation of platelets and potent anti-inflammatory efficacy.

Discovery of a brain-permeable bromodomain and extra terminal domain (BET) inhibitor with selectivity for BD1 for the treatment of multiple sclerosis. Eur J Med Chem 2024; 265:116080.

Abstract
Multiple sclerosis (MS) is a neuroinflammatory autoimmune disease and lacks effective therapeutic agents. Dysregulation of transcription mediated by bromodomain and extra-terminal domain (BET) proteins containing two different bromodomains (BD1 and BD2) is an important factor in multiple diseases, including MS. Herein, we identified a series of BD1-biased inhibitors, in which compound 16 showed nanomolar potency for BD1 (Kd = 230 nM) and a 60-fold selectivity for BRD4 BD1 over BD2. The co-crystal structure of BRD4 BD1 with 16 indicated that the hydrogen bond interaction of 16 with BD1-specific Asp145 is important for BD1 selectivity. 16 showed favorable brain distribution in mice and PK properties in rats. 16 was able to inhibit microglia activation and had significant therapeutic effects on EAE mice including improvement of spinal cord inflammatory conditions and demyelination protection. Overall, these results suggest that brain-permeable BD1 inhibitors have the potential to be further investigated as therapeutic agents for MS.

Abstract
BRD4 plays a key role in the regulation of gene transcription and has been identified as an attractive target for cancer treatment. In this study, we designed 26 new compounds by modifying 3-ethyl-benzo[d]isoxazole core with sulfonamides. Most compounds exhibited potent BRD4 binding activities with ΔTm values exceeding 6 °C. Two crystal structures of 11h and 11r in complex with BRD4(1) were obtained to characterize the binding patterns. Compounds 11h and 11r were effective for BRD4(1) binding and showed remarkable anti-proliferative activity against MV4-11 cells with IC50 values of 0.78 and 0.87 μM. Furthermore, 11r (0.5-10 μM) concentration-dependently inhibited the expression levels of oncogenes including c-Myc and CDK6 in MV4-11 cells. Moreover, 11r (0.5-10 μM) concentration-dependently blocked cell cycle in MV4-11 cells at G0/G1 phase and induced cell apoptosis. Compound 11r may serve as a new lead compound for further drug development.

Abstract
Androgen deprivation therapy (ADT) is a systemic therapy for advanced prostate cancer (PCa). Although most patients initially respond to ADT, almost all cancers eventually develop castration resistance. Castration-resistant PCa (CRPC) is associated with a very poor prognosis, and the treatment of which is a serious clinical challenge. Accumulating evidence suggests that abnormal expression and activation of various kinases are associated with the emergence and maintenance of CRPC. Many efforts have been made to develop small molecule inhibitors to target the key kinases in CRPC. These inhibitors are designed to suppress the kinase activity or interrupt kinase-mediated signal pathways that are associated with PCa androgen-independent (AI) growth and CRPC development. In this review, we briefly summarize the roles of the kinases that are abnormally expressed and/or activated in CRPC and the recent advances in the development of small molecule inhibitors that target kinases for the treatment of CRPC.

Abstract
Since androgen receptor (AR) can bind to BRD4 protein and this binding can be blocked by BRD4 inhibitors, targeting BRD4 has emerged as a promising approach for the treatment of prostate cancer (PC). Herein, we designed and synthesized a series of 5-(1-benzyl-1H-indazol-6-yl)-4-ethoxy-1-methylpyridin-2(1H)-one derivatives as novel BRD4 inhibitors for prostate cancer. Among them, compound 13 displayed the most robust BRD4 inhibitory activity with an IC50 value of 18 nM. Furthermore, 13 showed potent anti-proliferative activity against enzalutamide-resistant 22RV1 cells. The mechanism of action studies demonstrated that 13 induced cell apoptosis by regulating Bcl-2/Bax proteins and activating caspase-3 signaling pathway. In addition, the c-Myc level was significantly reduced in 22RV1 cells on the western blot assay. These findings collectively suggested that compound 13 might find potential use for the treatment of prostate cancer.

Abstract
Bromodomain and extra-terminal proteins (BETs) are potential targets for the therapeutic treatment of prostate cancer (PC). Herein, we report the design, the synthesis, and a structure-activity relationship study of 6-(3,5-dimethylisoxazol-4-yl)benzo[cd]indol-2(1H)-one derivative as novel selective BET inhibitors. One representative compound, 19 (Y06014), bound to BRD4(1) in the low micromolar range and demonstrated high selectivity for BRD4(1) over other non-BET bromodomain-containing proteins. This molecule also potently inhibited cell growth, colony formation, and mRNA expression of AR-regulated genes in PC cell lines. Y06014 also shows stronger activity than the second-generation antiandrogen enzalutamide. Y06014 may serve as a new small molecule probe for further validation of BET as a molecular target for PC drug development.

Abstract
The functions of the bromodomain and extra terminal (BET) family of proteins have been implicated in a wide range of diseases, particularly in the oncology and immuno-inflammatory areas, and several inhibitors are under investigation in the clinic. To mitigate the risk of attrition of these compounds due to structurally related toxicity findings, additional molecules from distinct chemical series were required. Here we describe the structure- and property-based optimization of the in vivo tool molecule I-BET151 toward I-BET282E, a molecule with properties suitable for progression into clinical studies.

Abstract
An efficient iridium-catalyzed enantioselective hydrogenation of 2-alkylidene 1,4-benzoxazin-3-ones using our developed iPr-BiphPHOX as a ligand is reported. This method showed good functional group compatibility and delivered the corresponding reduced products in excellent yields (up to 99%) with excellent enantioselectivities (up to 99% ee). The reaction proceeded very well on a gram scale with low catalyst loadings (0.1 mol %), providing the product with no erosion in enantioselectivity. Additionally, three bioactive molecules can be easily obtained from the reduced products.

Abstract
Targeting androgen receptor (AR) has been shown to be promising in treating glioblastoma (GBM) in cell culture and flank implant models but the mechanisms remain unclear. AR antagonists including enzalutamide are available for treating prostate cancer patients in clinic and can pass the blood-brain barrier, thus are potentially good candidates for GBM treatment but have not been tested in GBM orthotopically. Our current studies confirmed that in patients, a majority of GBM tumors overexpress AR in both genders. Enzalutamide inhibited the proliferation of GBM cells both in vitro and in vivo. Although confocal microscopy demonstrated that AR is expressed but not specifically in glioma cancer stem cells (CSCs) (CD133+), enzalutamide treatment significantly decreased CSC population in cultured monolayer cells and spheroids, suppressed tumor sphere-forming capacity of GBM cells, and downregulated CSC gene expression at mRNA and protein levels in a dose- and time-dependent manner. We have, for the first time, demonstrated that enzalutamide treatment decreased the density of CSCs in vivo and improved survival in an orthotopic GBM mouse model. We conclude that AR antagonists potently target glioma CSCs in addition to suppressing the overall proliferation of GBM cells as a mechanism supporting their repurposing for clinical applications treating GBM.

Synthesis and Biological Evaluation of Novel Isoxazole-Amide Analogues as Anticancer and Antioxidant Agents. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6633297. [PMID: 33763478 PMCID: PMC7963892 DOI: 10.1155/2021/6633297] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 02/02/2021] [Accepted: 02/17/2021] [Indexed: 12/11/2022]
Abstract
Cancer now is one of the leading causes of mortality in the world. There has been a lot of effort to discover new anticarcinogenic agents that allow treatment with fewer side effects. A series of isoxazole-carboxamide derivatives (2a–2g) were synthesised and evaluated for their cytotoxic activity against breast (MCF-7), cervical (HeLa), and liver (Hep3B) cancer cell lines and their antioxidant activity in the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The results showed that 2d and 2e were the most active compounds against Hep3B cells, with a half-maximal inhibitory concentration (IC50) of around 23 μg/ml; 2d showed the highest activity against HeLa cells, with an IC50 15.48 μg/ml. However, 2a had the lowest IC50 (39.80 μg/ml) against MCF-7 cells. By contrast, compound 2g was inactive against all cancer cell lines, with IC50 values >400 μg/ml. Both 2d and 2e reduced Hep3B secretion of alpha-fetoprotein (to 1829.33 ± 65.91 ng/ml and 1758.66 ± 54.04 ng/ml, respectively). Furthermore, in cell cycle analysis, 2d and 2e induced a delay in the G2/M phase of 18.07%, which is similar to the doxorubicin positive control. Moreover, 2d and 2e reduced the necrosis rate of Hep3B threefold and instead shifted the cells to apoptosis. Our results indicate that 2d and 2e have potent and promising anticancer activity. However, compound 2a was the most active as antioxidant agent (IC50 = 7.8 ± 1.21 μg/ml) compared with Trolox as a positive control (IC50 2.75 μg/ml).

Abstract
The efficient production of many medicinally or synthetically important starting materials suffers from wasteful or toxic precursors for the synthesis. In particular, the aromatic non-protected primary amine function represents a versatile synthetic precursor, but its synthesis typically requires toxic oxidizing agents and transition metal catalysts. The twofold electrochemical amination of activated benzene derivatives via Zincke intermediates provides an alternative sustainable strategy for the formation of new C-N bonds of high synthetic value. As a proof of concept, we use our approach to generate a benzoxazinone scaffold that gained attention as a starting structure against castrate-resistant prostate cancer. Further improvement of the structure led to significantly increased cancer cell line toxicity. Thus, exploiting environmentally benign electrooxidation, we present a new versatile and powerful method based on direct C-H activation that is applicable for example the production of medicinally relevant compounds.

Bioorg Chem 2019; 94:103424.

Abstract
Tripartite motif-containing protein 24 (TRIM24), recognized as an epigenetic reader for acetylated H3K23 (H3K23ac) via its bromodomain, has been closely involved in tumorigenesis or tumor progression of several cancers. Developing inhibitors of TRIM24 is significant for functional studies and drug discovery. Herein, we report the identification, optimization and evaluation of N-benzyl-3,6-dimethylbenzo[d]isoxazol-5-amines as TRIM24 bromodomain inhibitors starting from an in house library screening. Structure-based optimization leads to two potent and selective compounds 11d and 11h in an Alphascreen assay with IC50 values of 1.88 μM and 2.53 μM, respectively. The viability assay demonstrates the great potential of this series of compounds as inhibitors of proliferation of prostate cancer (PC) cells LNCaP, C4-2B. A colony formation assay further supports this inhibitory activity. Compounds 11d and 11h inhibit cell proliferation of other cancer types such as non-small cell lung cancer (NSCLC) cells A549 with IC50 values of 1.08 μM and 0.75 μM, respectively. These data suggests that compounds 11d and 11h are promising lead compounds for further research.

Y08197 is a novel and selective CBP/EP300 bromodomain inhibitor for the treatment of prostate cancer. Acta Pharmacol Sin 2019; 40:1436-1447.

Abstract
In advanced prostate cancer, CREB (cAMP-responsive element-binding protein) binding protein (CBP) and its homolog EP300 are highly expressed; targeting the bromodomain of CBP is a new strategy for the treatment of prostate cancer. In the current study we identified Y08197, a novel 1-(indolizin-3-yl) ethanone derivative, as a selective inhibitor of CBP/EP300 bromodomain and explored its antitumor activity against prostate cancer cell lines in vitro. In the AlphaScreen assay, we demonstrated that Y08197 dose-dependently inhibited the CBP bromodomain with an IC50 value at 100.67 ± 3.30 nM. Y08197 also exhibited high selectivity for CBP/EP300 over other bromodomain-containing proteins. In LNCaP, 22Rv1 and VCaP prostate cancer cells, treatment with Y08197 (1, 5 μM) strongly affected downstream signaling transduction, thus markedly inhibiting the expression of androgen receptor (AR)-regulated genes PSA, KLK2, TMPRSS2, and oncogenes C-MYC and ERG. Notably, Y08197 potently inhibited cell growth in several AR-positive prostate cancer cell lines including LNCaP, 22Rv1, VCaP, and C4-2B. In 22Rv1 prostate cancer cells, treatment with Y08197 (1, 4, 16 μM) dose-dependently induced G0/G1 phase arrest and apoptosis. Furthermore, treatment with Y08197 (5 μM) significantly decreased ERG-induced invasive capacity of 22Rv1 prostate cancer cells detected in wound-healing assay and cell migration assay. Taken together, CBP/EP300 inhibitor Y08197 represents a promising lead compound for development as new therapeutics for the treatment of castration-resistant prostate cancer.
