The aim of the present study was to model apparent serum half-lives of polybrominated diphenyl ethers (PBDEs) with 7-10 bromine substituents
For example, 1,3-DMU with 2 methyl substituents
was present in amounts ~5-fold less than those of monomethyl 7-MUA.
Chemists have tried to model these interactions by the synthesis of receptors that interact with sulfate via well-placed hydrogen bond donor groups and positively charged substituents
The four PDZ2-binding compounds identified in this work are all flavones sharing the same skeleton differing only in one of the substituents
in ring A and its location.
Aromatic compounds containing both electron donor and acceptor substituents
are highly polar and their UV spectra can be sensitive to solvent polarity and hydrogen bonding.
10:30 INFLUENCE OF AMINO SUBSTITUENTS
ON THE ENERGETICS OF ETHIDIUM-DNA COMPLEX FORMATION
One class of substituents
-- called ortho-para directors -- favors further substitutions mostly at the adjacent "ortho" carbon and at the "para" ring-site three carbons away.
Guide to Fluorine NMR for Organic Chemists provides a unique single source on both fluorine NMR and the impact of fluorine substituents
on proton and carbon NMR spectra.
In this proposal, we aim to develop first applications for two, previously very little explored non-covalent interactions that are based on electrophilic halogen or chalcogen substituents
( halogen-bonds and chalcogen bonds ).
Hypothesis: The reaction conducted on benzaldehydes with electron-withdrawing substituents
should result in a less pronounced shift towards the products of the secondary and tertiary Leuckart reactions.
Among the topics are computational approaches in agricultural research, the unique role of halogen substituents
in designing crop protection compounds, new targets for fungicides, ecological modeling in pesticide risk assessment, and an enquiry-led approach to generating data for the safety evaluation of new pesticide active ingredients.
All these complexes contain alkyl substituents
on the amido nitrogen.
