Synthesis and Performance Evaluation of a Novel High-Temperature-Resistant Thickener.

Successful exploitation of carbonate reservoirs relies on the acid-fracturing process, while the thickeners used in this process play a key role. It is a common engineering problem that thickeners usually fail to function when used in high-temperature environments. Until now, no research has ventured into the field of synthesizing thickeners which can be effectively used at ultra-high temperatures up to 180 °C.

N-terminal modified cyclopeptidic mimetics of Apollo as inhibitors of TRF2.

Telomeric repeat binding factor 2 (TRF2) plays an important role in protecting telomeres from being recognized as DNA breaks. TRF2 performs its telomere protecting functions partially by recruiting a number of accessory proteins to telomeres through its TRF homology (TFRH) domain. Identification of small molecular compounds which can bind to the TRFH domain of TRF2 and block the interactions between TRF2 and its associated proteins is crucial for elucidating the molecular mechanisms of these protein-protein interactions.

Development and optimization of a cascade of screening assays for inhibitors of TRF2.

TRF2 is a telomere associated protein which plays an important role in telomere maintenance. Knockdown of TRF2 can cause chromosomal end to end fusions and induce DNA damage responses. TRF2 exerts its functions partially by recruiting a number of accessory proteins through its TRF homology domain (TRFH), therefore identification of small molecular compounds which can bind to the TRFH domain of TRF2 and block the interactions of TRF2 with its associated proteins is important to elucidate the molecular mechanism of these protein-protein interactions.

Cyclic Peptidic Mimetics of Apollo Peptides Targeting Telomeric Repeat Binding Factor 2 (TRF2) and Apollo Interaction.

Telomeric repeat binding factor 2 (TRF2) is a telomere-associated protein that plays an important role in the formation of the 3' single strand DNA overhang and the "T loop", two structures critical for the stability of the telomeres. Apollo is a 5'-exonuclease recruited by TRF2 to the telomere and contributes to the formation of the 3' single strand DNA overhang. Knocking down of Apollo can induce DNA damage response similar to that caused by the knocking down of TRF2.
