Cyclic RGD peptidomimetics containing bifunctional diketopiperazine scaffolds as new potent integrin ligands [PDF]
, 2012 The synthesis of eight bifunctional diketopiperazine (DKP) scaffolds is described; these were formally derived from 2,3-diaminopropionic acid and aspartic acid (DKP-1-DKP-7) or glutamic acid (DKP-8) and feature an amine and a carboxylic acid functional ...

ChemPhotoChem, Volume 10, Issue 3, March 2026.Photoswitchable cyclic dipeptides (CDPs) can be used to prepare hydrogels that reversibly dissipate upon irradiation, or to photomodulate the development of living organisms. We report here applications and perspectives for CDPs containing azobenzene photoswitches or newly discovered hemipiperazine photoswitches in smart materials and biological ...

A Practical Sulfenylation of 2,5‐Diketopiperazines [PDF]
Angewandte Chemie, 2011 Sulfurs in action A practical and simple method for the introduction of sulfur atoms into 2,5-diketopiperazines (I) under mild conditions has been developed leading to more or less complex epidithiodiketopiperazines (II) and bis-methylthiodiketopiperazines (III).

ChemistrySelect, Volume 11, Issue 11, 18 March 2026.The tripeptide Pro‐Pro‐D‐hVal‐OMe, which lacks an acidic group, catalysed the conjugate addition of aldehydes to nitroolefins and afforded γ‐nitroaldehydes in 79–97% yield and 88:14–93:7 e.r. The proposed reaction mechanism relies on the active role of hydrazide NHβ or NHα protons in hydrogen bonding with the reacting species.

Angewandte Chemie, Volume 137, Issue 51, December 15, 2025.Tandem protein trans‐splicing (PTS) assembles a protein from three segments. Expanding this technology to individually treat cysteines in each segment, for example, for chemical labeling using thiol bioconjugation, the authors identify a second, highly efficient cysteine‐less split intein.

Chemistry – A European Journal, Volume 32, Issue 7, 16 February 2026.Conversion of emestrin J (5) to emestrin (1) by three P450 enzymes from the cluster (eme) in Emericella quadrilineata. EmeO acts as a bifunctional enzyme for the construction of the 15‐membered lactone ring via an aryl‐aryl ether bond formation and simultaneous hydroxylation between phenolic and nonphenolic aromatic rings, while EmeE and EmeR install ...
