Methylation Compound Library

338 compounds

Methylation is an epigenetic modification mechanism that involves adding methyl groups to molecules such as DNA and histones, which can alter gene expression without changing the DNA sequence. This process is catalyzed by enzymes such as DNA methyltransferases (DNMTs) and histone methyltransferases (HMTs), and can be reversed by demethylases. The balance of methylation and demethylation is crucial for maintaining cellular function and genomic stability. Abnormal regulation of methylation may lead to a variety of diseases, including cancer, neurological disorders, and developmental abnormalities. A deep understanding of the molecular mechanisms of methylation metabolism is essential for developing therapeutic strategies for diseases associated with methylation dysregulation.

MCE contains 338 compounds targeting methylation/demethylation enzymes, which is of significant value for studying the pathways of methylation metabolism and exploring their mechanisms of action in diseases.

Epigenetics Compound Library

1,945 compounds

Epigenetics refers to changes in phenotype that are not rooted in DNA sequence. Many types of epigenetic processes have been identified, including DNA methylation, alteration in the structure of histone proteins and gene regulation by small noncoding microRNAs. Modification of DNA, protein, or RNA, resulting in changes to the function and/or regulation of these molecules, without altering their primary sequences, reveals the complexities of cellular differentiation, embryology, the regulation of gene expression, aging, cancer, and other diseases.

MCE provide a unique collection of 1,945 epigenetics-related compounds that can be used in the research of the related diseases.

HY-L005M

Epigenetics Compound Library Mini

297 compounds

Epigenetics involves heritable phenotypic changes that occur without alterations to the underlying DNA sequence. Key mechanisms include DNA methylation, histone modifications, and regulation by small non-coding RNAs such as microRNAs. By modifying DNA, histones, or RNA—while leaving their primary sequences intact—these processes influence molecular function and regulation, thereby playing critical roles in cellular differentiation, embryonic development, gene expression control, aging, and diseases such as cancer.

MCE provide a unique collection of 297 epigenetics-related compounds. For each regulatory target and its subtype, 3 to 5 highly specific representative compounds have been retained, which can be used in epigenetic and related disease research.

Histone Modification Research Compound Library

904 compounds

A histone modification, a covalent post-translational modification (PTM) to histone proteins, includes methylation, phosphorylation, acetylation, ubiquitylation, and sumoylation, etc. In general, histone modifications are catalyzed by specific enzymes that act predominantly at the histone N-terminal tails involving amino acids such as lysine or arginine, as well as serine, threonine, tyrosine, etc. The PTMs made to histones can impact gene expression by altering chromatin structure or recruiting histone modifiers. Histone modifications act in diverse biological processes such as transcriptional activation/inactivation, chromosome packaging, and DNA damage/repair. Deregulation of histone modification contributes to many diseases, including cancer and autoimmune diseases.

MCE owns a unique collection of 904 bioactive compounds targeting Epigenetic Reader Domain, HDAC, Histone Acetyltransferase, Histone Demethylase, Histone Methyltransferase, Sirtuin, etc. Histone Modification Research Compound Library is a useful tool for histone modification research and drug screening.
