The discovery that a systemic human ribonuclease binds to a moiety displayed on human cancer cells links two clinical paradigms and suggests a mechanism for innate resistance to cancer.
In general, rhamnolipids contain one or two rhamnose moieties glycosidically bound to a lipid moiety made out of one, two or three β-hydroxy fatty acid chains which are in turn bound together through an ester bound (Abdel-Mawgoud et al. 2010).
Lipidic prodrugs, also called drug lipid conjugates, have the drug covalently bound to a lipid moiety, such as a fatty acid, a diglyceride or a phosphoglyceride.
It was interesting to note that ChEMBL 1454848 had a PAS unit covalently bound to a thiazolecoumarin moiety.
This behaviour is similar to what was found for the fragmentation of MeHgCys, and seems to be typical for mercury bound to a Cys moiety.
[44] Coordinates and restraint library files for the lysine residue covalently bound to a pyruvoyl moiety (HET code: KPI) were as previously described.
One of the recent approaches in which the drug is directly bound to a targeting moiety, for example, when norcantharidin directly bound to galactose group resulted in higher entrapment efficiency and low toxicity, still needs more focus to explore.
After translation, the Hh protein precursor undergoes auto-processing to release its N-terminal fragment (HhN), which is then covalently bound to a cholesterol moiety at the C-terminal end.
Because an α,β-unsaturated moiety can bind to a molecular target covalently, these compounds might induce a Ca2+ influx via covalent binding to the target.
We did not observe any soluble NE in the cytosol of activated neutrophils, suggesting that NE must be bound to an insoluble moiety.
