D-α-Hydroxyglutaric acid disodium [Disodium (R)-2-Hydroxyglutarate] is a competitive inhibitor of α-ketoglutarate-dependent dioxygenases with a Ki of 0.628 mM.

Maribavir (GW257406X) is an orally available benzimidazole riboside compound with activity against cytomegalovirus (CMV). Maribavir is a selective ATP competitor of the viral UL97 kinase, which is involved in viral nuclear maturation events, such as viral DNA assembly and movement of viral capsids from the nucleus of infected cells. Maribavir has activity against strains of CMV that are resistant to standard anti-CMV agents.

Transdermal Peptide is a 11-amino acid peptide, binds to Na+ K+-ATPase beta-subunit (ATP1B1), and enhances the transdermal delivery of many macromolecules. Transdermal Peptide (TD1) binds to ATP1B1, and mainly interacts with the C-terminus of ATP1B1 in yeast and mammalian cells. The interaction affects the expression and localization of ATP1B1 and epidermal structure, but can be antagonized by the exogenous competitor ATP1B1 or be inhibited by ouabain. Inhibition of Transdermal Peptide binding to ATP1B1 causes decreased delivery of macromolecular drugs across the skin[1]. [1]. Wang C, et al. Role of the Na(+) K(+)-ATPase beta-subunit in peptide-mediated transdermal drug delivery. Mol Pharm. 2015 Apr 6;12(4):1259-67.
