However, the pharmacokinetics and binding profiles of these agents are different [ 1].
These positive autoradiography results extend the findings of histology experimentations on the binding of the agent to PS.
The normalized SUV data indicate a higher retention of the tracer in cortex of transgenic mice compared with its WT counterpart following a clearance of the unbound tracer, a pharmacokinetic profile consistent with binding of the agent ([18F]-7B) with Aβ plaques in transgenic mice.
The pharmacodynamics studies on serially collected PBMC and tumor biopsies revealed limited bioavailability of UCN-01 to tissue, likely as a result of the high affinity binding of this agent to the α1-acid glycoprotein (AAG) [ 28, 39– 41].
Importantly, the addition of these residues did not alter the high affinity binding of nerve agents to this protein.
Based on these results and on what is known about the binding of carbamoylating agents to cellular macromolecules, methyl isocyanate may exert its genetic toxicity by binding to nuclear proteins rather than by binding to DNA.
If this contention were correct, then prior incubation of the rings with sevoflurane would prevent binding of agents that block these channels, and thereby abolish their effect.
These results demonstrate examples of a new platinum structural class targeting specific biological processes, distinct from the bifunctional DNA-DNA binding of cytotoxic agents like cisplatin.
The advantages of label-free imaging of chromosomes using STXM includes avoiding of the concerns such as non-uniform binding of labeling agents and photo-bleaching.
Selective binding of coordinating agents (cisplatin) to target molecules (DNA) and the contribution of H-bonding, electrostatic interactions, and steric effects in such binding are fundamentally important subjects.
