LC/MS/MS was used to map Cys 121 as having the highest selectivity for modification.
To improve their HDAC activity and selectivity, chemical modifications at the benzoyl moieties were investigated and evaluated using three maize histone deacetylases: HD2, HD1-B (class I human HDAC homologue), and HD1-A (class II human HDAC homologue).
(1S,2R,3S,4R,5S -4- 2- 5-Chlorothiophen-2-yl 1S,2R,3S,4R,5S -4- 2- 5-Chlorothiophen-2-yl 1S,2R,3S,4R,5S -4- 2- 5-Chlorothiophen-2-yl 1S,2R,3S,4R,5S -4- 2- 5-Chlorothiophen-2-yl 1S,2R,3S,4R,5S -4- 2- 5-Chlorothiophen-2-yl 1S,2R,3S,4R,5S -4- 2- 5-Chlorothiophen-2-yl 1S,2R,3S,4R,5S -4- 2- 5-Chlorothiophen-2-yly disethynyl -6- methylamino -9H-purin-9-yl -2,3-dihydroxy-N-methylbicyclo[3.1.0]hexane-1-carboxamide
The results showed that the two compounds had different modification selectivity to the four bases.
The modification selectivity of two compounds to the four nitrogenous bases on DNA sequence was also investigated in this study.
In static binding studies performed with adsorbents that had been exposed to plasmas at the 5 g scale (25 g L−1 of plasma reactor), the highest 'surface/core' modification selectivity was observed for Q HyperZ that had been subjected to 3 h of air plasma etching at 220 V (35.8 W L−1).
The selectivity of protein modification by the phospholipid aldehyde does not depend on the concentration of the oxidized phospholipid.
These observations collectively suggest that the direct binding of photosensitizers to specific proteins may guide the selectivity of protein modification in PDT-treated cells.

Herein, we report that Pt on alumina catalysts exhibit an exceedingly enhanced activity and selectivity after surface modification with a thin-film coating of hygroscopic and basic inorganic salts.
