Anticancer activity of the liposome-encapsulated cyclic dipeptides, cyclo(His-Gly) and cyclo(His-Ala) [PDF]
, 2013 Cyclic dipeptides have been well characterized for their biological activity, including antimicrobial and anticancer activities. Cyclo(His-Gly) and cyclo(His-Ala) have also recently demonstrated significant anticancer activity against a range of cell ...

Photoelectron spectra and structures of three cyclic dipeptides: PhePhe, TyrPro and HisGly [PDF]
, 2012 We have investigated the electronic structure of three cyclic dipeptides: cyclo(Histidyl-Glycyl) (cHisGly), cyclo(Tyrosyl-Prolyl) (cTyrPro), and cyclo(Phenylalanyl-Phenylalanyl) (cPhePhe) in the vapor phase, by means of photoemission spectroscopy and ...

Synthesis and Antimalarial Evaluation of Cyclic β-Amino Acid-Containing Dipeptides
Molecules, 2008 This paper describes an efficient synthesis and the antiparasitic evaluation ofcyclic β-amino acid-containing dipeptides 3.1-3.6 and 4.1-4.5. The antimalarial propertiesof all these dipeptides have been evaluated in vitro against Plasmodium falciparum

Advanced Science, EarlyView.Under 660 nm visible light, Ru NCs efficiently photocatalyze nitrate‐to‐ammonium conversion and modulate oral nitrogen metabolism. They precisely perturb Veillonella parvula, block its key support to Porphyromonas gingivalis, and exert an “inhibiting without killing” antivirulence effect.

An Update on 2,5-Diketopiperazines from Marine Organisms
Marine Drugs, 2014 2,5-Diketopiperazines (2,5-DKPs) are an important category of structurally diverse cyclic dipeptides with prominent biological properties. These 2,5-DKPs have been obtained from a variety of natural resources, including marine organisms.

Targeting WDR12 Unleashes T‐Cell‐Mediated Antitumor Activity in Melanoma by Destabilizing CD276
Advanced Science, EarlyView.WDR12 cooperates with the chaperonin subunit CCT7 to maintain CD276 stability on tumor cells, suppressing T‐cell activity and promoting immune escape. SU14813, a small‐molecule WDR12 inhibitor, reduces CD276 stability and relieves CD276‐mediated T‐cell suppression.

Energetics of Cyclic Dipeptide Crystal Packing and Solvation
Biophysical Journal, 1997 Calculations of the thermodynamics of transfer of the cyclic alanine-alanine (cAA) and glycine-glycine (cGG) dipeptides between the gas, water, and crystal phases were carried out using a combination of molecular mechanics, normal mode analysis, and continuum electrostatics. The experimental gas-to-water solvation free energy and the enthalpy of gas-to-
