The methylation of lysine residues on histones plays a central role in determining euchromatin structure and gene expression. The histone methyltransferase (HMTase) G9a can mono- or dimethylate lysine 9 on histone 3 (H3), contributing to early embryogenesis, genomic imprinting, and lymphocyte development.1,2,3 UNC0638 is a potent G9a HMTase inhibitor, exhibiting an IC50 value of <15 nM in vitro. UNC0638 also inhibits GLP, a closely-related H3K9 HMTase, with an IC50 value of 19 nM, but is more than 10,000-fold selective against SET7/9 (a H3K4 HMTase), SET8 (a H4K20 HMTase), PRMT3, and SUV39H2. UNC0638 inhibits H3K9 dimethylation in MDA-MB231 cells with an IC50 value of 81 nM and demonstrates favorable separation of functional and toxic effects.4

Cayman Chemical Company regularly evaluates our shipping methods to ensure product stability is maintained and our corporate environmental impact is minimized. Products selected for review are evaluated and shipping methods are certified by our Scientists. While occasionally our method of shipping a product may change, rest assured the shipping conditions on all Cayman Chemical products have been reviewed and validated.
Upon receipt, it is important to check the storage requirements of your products and place them at the appropriate temperature. Products shipped without ice may require frozen storage for long term stability.
Cayman Chemical was formed over thirty years ago by demonstrating the value of naturally growing gorgonian corals as a renewable, economically viable source of prostaglandins. Today we operate our business knowing that we owe our start to the renewable resources our environment had provided. As Cayman Chemical continues to grow we consistently evaluate our business processes to ensure we are operating at the highest environmental standards.
