Several steps, such as redox reaction sulfidation, phosphorylation and molecular modification, are involved in biotransformation [50].
Therefore, in-depth understanding of their electronic-structure properties and rational molecular modifications are urgently required.
Through rational design several novel imidazoquinoline and oxoadenine TLR7/8 agonists, each with unique molecular modifications, were synthesized and assessed for their ability to augment adaptive immunity.
The understandings of the electronic structure and optical properties according to the molecular modifications are useful in the rational design of the zinc-porphyrin-based sensitizer in the solar cells.
With C214 as a prototype, molecular modifications are then made and a scheme, using NH groups to connect neighboring phenyls in the triphenylamine donor, has been demonstrated to be successful to significantly red-shift the absorption maximum wavelength, extend the lifetime of the first excited state, and decrease the energy gap between HOMO and LUMO.
An increase in activity after molecular modifications was also observed in several of our piggyBac chimeras including the GAL4- piggyBac which displayed a fluctuated activity that was sometimes higher than the wild-type piggyBac transposase (15 and Meir et. al., unpublished observations).
PBI molecular structure modification is a viable approach to disrupt chain packing altering the free-volume architecture which results in improved gas transport characteristics.
The observed gain in molecular weight per modification is bigger than the expected 5 kDa for each Cys, but this can be attributed to an aberrant mobility of the modified protein in the Bis-Tris/SDS-PAGE used in the assay.
Among studied characteristics, flower color is one of the most targeted traits in molecular investigations, as flower color modification is of strong interest from both basic and applied research perspectives.
