摘要:
N-n-Alkylation of nicotine converts nicotine from an agonist into an antagonist specifically for neuronal nicotinic acetylcholine receptor subtypes mediating nicotine-evoked dopamine release. Conformationally restricted analogs exhibit both high affinity and selectivity at this site, and are able to access the brain due to their ability to act as substrates for the blood-brain barrier choline transporter.

Bleach boosters comprising zwitterionic imines and anionic imine polyions having a net negative charge are disclosed. The bleach boosters increase bleaching effectiveness in lower temperature solutions and demonstrate superior color safety profiles. The bleach boosters are ideally suited for inclusion into bleaching compositions including those with detersive surfactants and enzymes. Also provided is a laundry additive product including zwitterionic imines and anionic imine polyions with a net negative charge as bleach boosters. A method for laundering a fabric employing the bleach boosters of the present invention is also disclosed.

摘要:
A charge transfer complex comprising N,N'-alkylene-di-3,5-lutidine as a donor and 7,7,8,8-tetracyanoquinodimethane as an acceptor, the molar ratio of the acceptor to the donor of the charge transfer complex being between 3.0 and 5.0 has a high melting point and excellent electrical conductivity as an electrolyte for a capacitor. A solid electrolytic capacitor employing said charge transfer complex has reduced current leakage and high temperature load characteristics. A chip-type solid electrolytic capacitor employing said charge transfer complex has reduced current leakage, high temperature load characteristics and excellent thermal stability and life characteristics.
