ZLD1039 is an inhibitor of enhancer of zeste homolog 2 (EZH2; IC50 = 5.6 nM).1 It is selective for EZH2 over EZH1 (IC50 = 81 nM) and is greater than 4,700-fold selective for EZH2 in a panel of 14 histone methyltransferases. ZLD1039 also inhibits mutant Y641F and A677G EZH2 (IC50s = 15 and 4 nM, respectively, in a cell-free enzyme assay). It inhibits methylation of histone 3 lysine 27 (H3K27) in MCF-7 breast cancer cells (IC50 = 0.29 μM) and decreases expression of cadherin-1 (CDH1), cyclin-dependent kinase inhibitor 1C (CDKN1C), CDKN2A, and runt-related transcription factor 3 (RUNX3) in MCF-7 cells when used at concentrations of 1 and 2 μM. It also suppresses migration of MCF-7 cells when used at a concentration of 2 μM. ZLD1039 (200 mg/kg) reduces tumor growth in MCF-7 and MDA-MB-231 mouse xenograft models and inhibits tumor metastasis and decreases tumor protein levels of matrix metalloproteinase-2 (MMP-2), MMP-9, and E-cadherin in a 4T1 mouse xenograft model when administered at a dose of 250 mg/kg.

Selective EZH2 inhibitor ZLD1039 alleviates inflammation in cisplatin-induced acute kidney injury partially by enhancing RKIP and suppressing NF-κB p65 pathway
Acta Pharmacol Sin 2022 Aug;43(8):2067-2080.PMID:PMC9343430DOI:10.1038/s41401-021-00837-8.
Enhancer of zeste homolog 2 (EZH2), a component of polycomb repressive complex 2 (PRC2), is a histone lysine methyltransferase mediating trimethylation of histone H3 at lysine 27 (H3K27me3), which is a repressive marker at the transcriptional level. EZH2 sustains normal renal function and its overexpression has bad properties. Inhibition of EZH2 overexpression exerts protective effect against acute kidney injury (AKI). A small-molecule compound ZLD1039 has been developed as an efficient and selective EZH2 inhibitor. In this study, we evaluated the efficacy of ZLD1039 in the treatment of cisplatin-induced AKI in mice. Before injection of cisplatin (20 mg/kg, i.p.), mice were administered ZLD1039 (100, 200 mg/kg, i.g.) once, then in the following 3 days. We found that cisplatin-treated mice displayed serious AKI symptoms, evidenced by kidney dysfunction and kidney histological injury, accompanied by EZH2 upregulation in the nucleus of renal tubular epithelial cells. Administration of ZLD1039 dose-dependently alleviated renal dysfunction as well as the histological injury, inflammation and cell apoptosis in cisplatin-treated mice. We revealed that ZLD1039 administration exerted an anti-inflammatory effect in kidney of cisplatin-treated mice via H3K27me3 inhibition, raf kinase inhibitor protein (RKIP) upregulation and NF-κB p65 repression. In the cisplatin-treated mouse renal tubular epithelial (TCMK-1) cells, silencing of RKIP with siRNA did not abolish the anti-inflammatory effect of EZH2 inhibition, suggesting that RKIP was partially involved in the anti-inflammatory effect of ZLD1039. Collectively, EZH2 inhibition alleviates inflammation in cisplatin-induced mouse AKI via upregulating RKIP and blocking NF-κB p65 signaling in cisplatin-induced AKI. The potent and selective EZH2 inhibitor ZLD1039 has the potential as a promising agent for the treatment of AKI.
Pharmacological inhibition of EZH2 by ZLD1039 suppresses tumor growth and pulmonary metastasis in melanoma cells in vitro and in vivo
Biochem Pharmacol 2023 Apr;210:115493.PMID:36898415DOI:10.1016/j.bcp.2023.115493.
The incidence and mortality rate of malignant melanoma are increasing worldwide. Metastasis reduces the efficacy of current melanoma therapies and leads to poor prognosis for patients. EZH2 is a methyltransferase that promotes the proliferation, metastasis, and drug resistance of tumor cells by regulating transcriptional activity. EZH2 inhibitors could be effective in melanoma therapies. Herein, we aimed to investigate whether the pharmacological inhibition of EZH2 by ZLD1039, a potent and selective S-adenosyl-l-methionine-EZH2 inhibitor, suppresses tumor growth and pulmonary metastasis in melanoma cells. Results showed that ZLD1039 selectively reduced H3K27 methylation in melanoma cells by inhibiting EZH2 methyltransferase activity. Additionally, ZLD1039 exerted excellent antiproliferative effects on melanoma cells in 2D and 3D culture systems. Administration of ZLD1039 (100 mg/kg) by oral gavage caused antitumor effects in the A375 subcutaneous xenograft mouse model. RNA sequencing and GSEA revealed that the ZLD1039-treated tumors exhibited changes in the gene sets enriched from the "Cell Cycle" and "Oxidative Phosphorylation", whereas the "ECM receptor interaction" gene set had a negative enrichment score. Mechanistically, ZLD1039 induced G0/G1 phase arrest by upregulating p16 and p27 and inhibiting the functions of the cyclin D1/CDK6 and cyclin E/CDK2 complexes. Moreover, ZLD1039 induced apoptosis in melanoma cells via the mitochondrial reactive oxygen species apoptotic pathway, consistent with the changes in transcriptional signatures. ZLD1039 also exhibited excellent antimetastatic effects on melanoma cells in vitro and in vivo. Our data highlight that ZLD1039 may be effective against melanoma growth and pulmonary metastasis and thus could serve as a therapeutic agent for melanoma.
Selective inhibition of EZH2 by ZLD1039 blocks H3K27 methylation and leads to potent anti-tumor activity in breast cancer
Sci Rep 2016 Feb 12;6:20864.PMID:26868841DOI:10.1038/srep20864.
Enhancer of zeste homolog 2 (EZH2) is a candidate oncogenic driver due to its prevalent overexpression and aberrant repression of tumor suppressor genes in diverse cancers. Therefore, blocking EZH2 enzyme activity may present a valid therapeutic strategy for the treatment of cancers with EZH2 overexpression including breast cancers. Here, we described ZLD1039 a potent, highly selective, and orally bioavailable small molecule inhibitor of EZH2, which inhibited breast tumor growth and metastasis. ZLD1039 considerably inhibited EZH2 methyltransferase activity with nanomolar potency, decreased global histone-3 lysine-27 (H3K27) methylation, and reactivated silenced tumor suppressors connected to increased survival of patients with breast cancer. Comparable to conditional silencing of EZH2, its inhibition by ZLD1039 decreased cell proliferation, cell cycle arrest, and induced apoptosis. Comparably, treatment of xenograft-bearing mice with ZLD1039 led to tumor growth regression and metastasis inhibition. These data confirmed the dependency of breast cancer progression on EZH2 activity and the usefulness of ZLD1039 as a promising treatment for breast cancer.
