Exploring the full range of N ⋯I⋯X halogen-bonding interactions within a single compound using pressure
Chem Commun (Camb). 2024 Apr 9. doi: 10.1039/d4cc00847b. Online ahead of print.ABSTRACTThe response of the trimethylammonium-iodinechloride and diiodide (TMA-ICl/I2) crystal structures have been examined under high pressure using neutron powder diffraction.

Enhancing APE1 detection through apurinic/apyrimidinic site inhibition of DNA polymerase: an innovative, highly sensitive approach
This study presents an innovative method for the highly sensitive detection of apurinic/apyrimidinic endonuclease 1 (APE1), a crucial biomarker and target for cancer diagnosis and treatment. The method is predicated on our discovery that the apurinic or apyrimidinic site (AP site) can inhibit the activity of Taq DNA polymerase. Subsequent experiments further led to the development of a new amplification method based on the digestion activity of Lambda exonuclease. This approach showed potential to detect trace amounts of APE1 in biological samples with high sensitivity.PMID:38592754 | DOI:10.1039/d4cc00304g (Source: Chemical Communications)
