Intrinsic Hydrophobicity versus Intraguest Interactions in Hydrophobically Driven Molecular Recognition in Water

Molecular recognition of water-soluble molecules is challenging but can be achieved if the receptor possesses a hydrophobic binding interface complementary to the guest. When the guest molecule contains more than one hydrophobic group, intrahost interactions between the hydrophobes could strongly influence the binding of the guest by its host. In a series of ornithine derivatives functionalized with aromatic hydrophobes, the most electron-rich compound displayed the strongest binding, despite its lowest intrinsic hydrophobicity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of: 4,4-Dimethylpiperidine-2,6-dione, you can also check out more blogs about1123-40-6

A Selenourea-Thiourea Br¡ãnsted Acid Catalyst Facilitates Asymmetric Conjugate Additions of Amines to alpha,beta-Unsaturated Esters

beta-Amino esters are obtained with high levels of enantioselectivity via the conjugate addition of cyclic amines to unactivated alpha,beta-unsaturated esters. A related strategy enables the kinetic resolution of racemic cyclic 2-arylamines, using benzyl acrylate as the resolving agent. Reactions are facilitated by an unprecedented selenourea-thiourea organocatalyst. As elucidated by DFT calculations and 13C kinetic isotope effect studies, the rate-limiting and enantiodetermining step of the reaction is the protonation of a zwitterionic intermediate by the catalyst. This represents a rare case in which a thiourea compound functions as an asymmetric Br¡ãnsted acid catalyst.

Self-activated supramolecular reactions: Effects of host-guest recognition on the kinetics of the Diels-Alder reaction of open-chain oligoether quinones with cyclopentadiene

Diels-Alder reactions of acyclic oligoether-substituted quinones 1b, 1c, 2b, and 2c with cyclopentadiene were accelerated by the addition of alkali and alkaline earth metal perchlorates, and scandium trifluoromethane sulfonate (kc/kf = 1.2-23 for univalent cations, 11-1160 for divalent cations, and 1700-192 000 for Sc3+, where kc and kf are the rate constants for the metal complexed and uncomplexed quinones, respectively). The shorter-armed 1a, 2a, and 3, however, exhibited no such acceleration effects. The rate accelerations can be rationalized by the FMO consequence in which the bound guest cation withdraws electron density from the quinone dienophile and lowers the LUMO energy suitable for the orbital interaction with the HOMO of cyclopentadiene. Despite the poor cation selectivity, these acyclic oligoether quinones showed larger rate accelerations than the relevant quinocrown ethers 4 (kc/kf = 1.3-3.0 for univalent cations, 5.0-160 for divalent cations, and 100-2020 for Sc3+). The effective electron withdrawal, which leads to the enhanced rate acceleration, can be caused by the direct interaction between the metal cation accommodated in the pseudo-cyclic oligoether linkage and the quinone carbonyl oxygen, as indicated by 1H NMR spectroscopy. In addition, the larger rate enhancement is rather achieved in the complex with low binding constant K, because the strong encapsulation of metal cation by the oligoether chain diminishes the crucial interaction to the quinone carbonyl oxygen. As a whole, the smaller and higher valent cations tend to bring about notable rate acceleration due to the more enhanced ion- dipole interaction with the quinone carbonyl oxygen. Spectroscopic titration (absorption and 1H NMR) and kinetic experiments indicated that only the longest di-armed 2c constructs 1:1, and then 1:2, host/guest complexes with Ca2+, Sr2+, and Ba2+. These 1:2 complexes exhibited the most effective acceleration for the respective metal cations.

Reagents for assaying central local acetylcholinesterase activity

The present invention relates to N-alkylpiperidine derivatives represented by general formula (1) or (2); wherein R1 represents optionally fluorinated lower alkyl; R2 represents lower alkyl; and R3 represents alkenyl substituted at the 1-position with hydroxy, lower alkoxy, lower alkoxyalkyloxy, lower alkoxyalkyloxyalkyloxy, or lower alkanoyloxy and substituted at the end with radioactive iodine, or alkenyloxymethyl substituted at the end with a radioactive iodine reagent containing the same for assaying central local AchE activity; a method for assaying the central local AchE activity; and labeled precursors of the above compounds. After easily passing through the blood-brain barrier, these compounds are hydrolyzed specifically by AchE in the brain into alcohols, which are then captured by the brain. In contrast, alcohols formed outside the brain do not migrate into the brain. The compounds of the invention emit gamma-rays at an appropriate energy level. These characteristics make the compounds highly useful as tracers for SPECT in assaying the central AchE activity.
