These absorptions along with the disappearance of NH absorption in the region 3200-3300 cm-1 indicated the cyclization
of diphenyl thiourea to the corresponding 3-phenyl-2-(phenylimino)thiazolidin-4-one.
Although comparisons of the cyclization
sequences (online Technical Appendix Figure, panel C) indicate a high level of conservation among all members of the YFV group, alignments of the upstream AUG region (online Technical Appendix Figure, panel D) highlight a clear separation of FRV, SEPV, and WESSV from YFV.
sup] The combination of this mutation with the frame shift mutation in a compound heterozygote may play a role in the slow clearance of conjugated bilirubin and/or the expression of enzymes involved in the cyclization
Heat releases the trigger group, which induces depolymerization by group elimination, cyclization
and monomer formation.
Formaldehyde-mediated modification of deoxyguanosine with amines: one-pot cyclization
as a molecular model for genotoxicity.
A novel class of self-assembled catalysts will be developed which are able to control the conformation of the substrate, thereby allowing for selectivity in the cyclization
This modification not only can help to initiate the cyclization
reaction and reduce the heat evolved of PAN precursors, but also can shorten the residence time of stabilization.
This indicates that the size of the phenolic, in addition the class where they belong as well as the cyclization
as indicated above, play an important role in their cytotoxicity.
The most commonly used reactions for pyridine synthesis are Chichibabin synthesis, Bonnemann cyclization
, and Cobalt-catalyzed alkyne-nitrile cyclotrimerization, etc.
The researchers soon found that assembly steps could be classified into endless variations of three basic types: dimerization (when one protein doubles to become two), cyclization
(when one protein forms a ring of three or more) and subunit addition (when two different proteins bind to each other).
The formation of some fatty acid oxidation products may be rationalized by pathways involving dioxetanyl derivatives formed by cyclization
of peroxyl radicals.
These glycated proteins undergo progressive dehydration, cyclization
, oxidation and rearrangement to form Advanced Glycation End Products (AGE's).
