Abstract
CARM1 is amplified or overexpressed in many cancer types, and its overexpression correlates with poor prognosis. Potent small-molecule inhibitors for CARM1 have been developed, but the cellular efficacy of the CARM1 inhibitors is limited. We herein report the development of the proteolysis targeting chimera (PROTAC) for CARM1, which contains a CARM1 ligand TP-064, a linker, and a VHL E3 ligase ligand. Compound 3b elicited potent cellular degradation activity (DC50 = 8 nM and Dmax > 95%) in a few hours. Compound 3b degraded CARM1 in VHL- and proteasome-dependent manner and was highly selective for CARM1 over other protein arginine methyltransferases. CARM1 degradation by 3b resulted in potent downregulation of CARM1 substrate methylation and inhibition of cancer cell migration in cell-based assays. Thus, CARM1 PROTACs can be used to interrogate CARM1's cellular functions and potentially be developed as therapeutic agents for targeting CARM1-driven cancers.

Abstract
Coactivator-associated arginine methyltransferase 1 (CARM1), a type I protein arginine methyltransferase (PRMT), has been widely reported to catalyze arginine methylation of histone and non-histone substrates, which is closely associated with the occurrence and progression of cancer. Recently, accumulating studies have demonstrated the oncogenic role of CARM1 in many types of human cancers. More importantly, CARM1 has been emerging as an attractive therapeutic target for discovery of new candidate anti-tumor drugs. Therefore, in this review, we summarize the molecular structure of CARM1 and its key regulatory pathways, as well as further discuss the rapid progress in better understanding of the oncogenic functions of CARM1. Moreover, we further demonstrate several representative targeted CARM1 inhibitors, especially focusing on demonstrating their designing strategies and potential therapeutic applications. Together, these inspiring findings would shed new light on elucidating the underlying mechanisms of CARM1 and provide a clue on discovery of more potent and selective CARM1 inhibitors for the future targeted cancer therapy.

Abstract
Dysregulation of the epigenetic processes, such as DNA methylation, histone modifications, and modulation of chromatin states, drives aberrant transcription that promotes initiation and progression of small cell lung cancer (SCLC). Accumulating evidence has proven crucial roles of epigenetic machinery in modulating immune cell functions and antitumor immune response. Epigenetics-targeting drugs such as DNA methyltransferase inhibitors, histone deacetylase inhibitors, and histone methyltransferase inhibitors involved in preclinical and clinical trials may trigger antitumor immunity. Herein, we summarize the impact of epigenetic processes on tumor immunogenicity and antitumor immune cell functions in SCLC. Furthermore, we review current clinical trials of epigenetic therapy against SCLC and the mechanisms of epigenetic inhibitors to boost antitumor immunity. Eventually, we discuss the opportunities of developing therapeutic regimens combining epigenetic agents with immunotherapy for SCLC.

Abstract
CARM1 is a protein arginine methyltransferase and acts as a transcriptional coactivator regulating multiple biological processes. Aberrant expression of CARM1 has been related to the progression of multiple types of cancers, and therefore CARM1 was considered as a promising drug target. In the present work, we report the structure-based discovery of a series of N1-(3-(pyrimidin-2-yl)benzyl)ethane-1,2-diamines as potent CARM1 inhibitors, in which compound 43 displays high potency and selectivity. With the advantage of excellent tissue distribution, compound 43 demonstrated good in vivo efficacy for solid tumors. Furthermore, from the detailed immuno-oncology study with MC38 C57BL/6J xenograft model, we confirmed that this chemical probe 43 has profound effects in tumor immunity, which paves the way for future studies on the modulation of arginine post-translational modification that could be utilized in solid tumor treatment and cancer immunotherapy.

Abstract
Arginine methylation is considered to be one of the most permanent and one of the most frequent post-translational modifications. The reaction of transferring a methyl group from S-adenosylmethionine to arginine residue is catalyzed by aginine methyltransferase (PRMT). In humans there are nine members of the PRMT family, named in order of discovery of PRMT1- PRMT9. Arginine methyltransferases were divided into three classes: I, II, III, with regard to the product of the catalyzed reaction. The products of their activity are, respectively, the following: asymmetric dimethylarginine (ADMA), symmetrical dimethylarginine (SDMA) and monomethylarginine (MMA). These modifications significantly affect the chromatin functions; therefore, they can act as co-activators or suppressors of the transcription process. Arginine methylation plays a crucial role in many biological processes in a human organism. Among others, it participates in signal transduction control, mRNA splicing and the regulation of basic cellular processes such as proliferation, differentiation, migration and apoptosis. There is increasing evidence that dysregulation of PRMT levels may lead to the cancer transformation of cells. The correlation between increased PRMT level and cancer has been demonstrated in the following: breast, ovary, lung and colorectal cancer. The activity of arginine methyltransferase can be regulated by small molecule PRMT inhibitors. To date, three substances that inhibit PRMT activity have been evaluated in clinical trials and exhibit anti-tumor activity against hematological cancer. It is believed that the use of specific PRMT inhibitors may become a new, effective and safe treatment of oncological diseases.

Abstract
DNA, RNA and histone methylation is implicated in various human diseases such as cancer or viral infections, playing a major role in cell process regulation, especially in modulation of gene expression. Here we developed a convergent synthetic pathway starting from a protected bromomethylcytosine derivative to synthesize transition state analogues of the DNA methyltransferases. This approach led to seven 5-methylcytosine-adenosine compounds that were, surprisingly, inactive against hDNMT1, hDNMT3Acat, TRDMT1 and other RNA human and viral methyltransferases. Interestingly, compound 4 and its derivative 2 showed an inhibitory activity against PRMT4 in the micromolar range. Crystal structures showed that compound 4 binds to the PRMT4 active site, displacing strongly the S-adenosyl-l-methionine cofactor, occupying its binding site, and interacting with the arginine substrate site through the cytosine moiety that probes the space filled by a substrate peptide methylation intermediate. Furthermore, the binding of the compounds induces important structural switches. These findings open new routes for the conception of new potent PRMT4 inhibitors based on the 5-methylcytosine-adenosine scaffold.This article is part of a discussion meeting issue 'Frontiers in epigenetic chemical biology'.

Abstract
Glucose is a critical nutrient for cell proliferation. However, the molecular pathways that regulate glucose metabolism are still elusive. We discovered that co-activator-associated arginine methyltransferase 1 (CARM1) suppresses glucose metabolism toward serine biosynthesis. By tracing the 13C-labeled glucose, we found that Carm1 knockout mouse embryonic fibroblasts exhibit significantly increased de novo serine synthesis than WT cells. This is caused, at least in part, by the reduced pyruvate kinase (PK) activity in these cells. The M2 isoform of PK (PKM2) is arginine-methylated by CARM1, and methylation enhances its activity. Mechanistically, CARM1 methylates PKM2 at arginines 445 and 447, which enhances PKM2 tetramer formation. Consequently, Carm1 knockout cells exhibit significant survival advantages over WT cells when extracellular serine is limited, likely due to their enhanced de novo serine synthesis capacity. Altogether, we identified CARM1 as an important regulator of glucose metabolism and serine synthesis.

Abstract
Squamous cell carcinoma of the head and neck is a lethal disease with suboptimal survival outcomes and standard therapies with significant comorbidities. Whole exome sequencing data recently revealed an abundance of genetic and expression alterations in a family of enzymes known as protein methyltransferases in a variety of cancer types, including squamous cell carcinoma of the head and neck. These enzymes are mostly known for their chromatin-modifying functions through methylation of various histone substrates, though evidence supports their function also through methylation of non-histone substrates. This review summarizes the current knowledge on the function of protein methyltransferases in squamous cell carcinoma of the head and neck and highlights their promising potential as the next generation of therapeutic targets in this disease.

Abstract
DNA and histone methylation belong to the key regulatory components in the epigenetic machinery, and dysregulations of these processes have been associated with various human diseases. Small molecule modulators of these epigenetic targets are highly valuable both as chemical probes to study the biological roles of the target proteins, and as potential therapeutics. Indeed, recent years have seen the discovery of chemical modulators of several epigenetic targets, some of which are already marketed drugs or undergoing clinical trials. In this review, we will focus on small molecule modulators of DNA and histone methylation.

Abstract
Neuroblastoma is a cancer of the neural crest almost exclusively seen in childhood. While children with single, small primary tumors are often cured with surgery alone, the 65% of children with neuroblastoma whose disease has metastasized have less than a 50% chance of surviving five years after diagnosis. Innovative pharmacological strategies are critically needed for these children. Efforts to identify novel targets that afford ablation of neuroblastoma with minimal toxicity to normal tissues are underway. Developing approaches to neuroblastoma include those that target the catecholamine transporter, ubiquitin E3 ligase, the ganglioside GD2, the retinoic acid receptor, the protein kinases ALK and Aurora, and protein arginine N-methyltransferases. Here, as examples of the use of chemistry to combat neuroblastoma, we describe targeting of the protein arginine N-methyltransferases and their role in prolonging the half-life of the neuroblastoma oncoprotein N-Myc, redox signaling in neuroblastoma, and developmentally regulated proteins expressed in primitive neuroblastoma cells but not in mature neural crest elements.

Abstract
Mounting evidence suggests that protein methyltransferases (PMTs), which catalyze methylation of histones as well as non-histone proteins, play a crucial role in diverse biological pathways and human diseases. In particular, PMTs have been recognized as major players in regulating gene expression and chromatin state. There has been an increasingly growing interest in these enzymes as potential therapeutic targets and over the past two years tremendous progress has been made in the discovery of selective, small molecule inhibitors of protein lysine and arginine methyltransferases. Inhibitors of PMTs have been used extensively in oncology studies as tool compounds, and inhibitors of EZH2, DOT1L and PRMT5 are currently in clinical trials.

Abstract
![]()
Post-translational
modifications of histones by protein methyltransferases
(PMTs) and histone demethylases (KDMs) play an important role in the
regulation of gene expression and transcription and are implicated
in cancer and many other diseases. Many of these enzymes also target
various nonhistone proteins impacting numerous crucial biological
pathways. Given their key biological functions and implications in
human diseases, there has been a growing interest in assessing these
enzymes as potential therapeutic targets. Consequently, discovering
and developing inhibitors of these enzymes has become a very active
and fast-growing research area over the past decade. In this review,
we cover the discovery, characterization, and biological application
of inhibitors of PMTs and KDMs with emphasis on key advancements in
the field. We also discuss challenges, opportunities, and future directions
in this emerging, exciting research field.

Abstract
Well-characterized selective inhibitors of protein arginine methyltransferases (PRMTs) are invaluable chemical tools for testing biological and therapeutic hypotheses. Based on 4, a fragment-like inhibitor of type I PRMTs, we conducted structure-activity relationship (SAR) studies and explored three regions of this scaffold. The studies led to the discovery of a potent, selective, and cell-active dual inhibitor of PRMT4 and PRMT6, 17 (MS049). As compared to 4, 17 displayed much improved potency for PRMT4 and PRMT6 in both biochemical and cellular assays. It was selective for PRMT4 and PRMT6 over other PRMTs and a broad range of other epigenetic modifiers and nonepigenetic targets. We also developed 46 (MS049N), which was inactive in biochemical and cellular assays, as a negative control for chemical biology studies. Considering possible overlapping substrate specificity of PRMTs, 17 and 46 are valuable chemical tools for dissecting specific biological functions and dysregulation of PRMT4 and PRMT6 in health and disease.
