COMPOUNDS AND COMPOSITIONS FOR INTRACELLULAR DELIVERY OF AGENTS
-
Paragraph 001000, (2019/01/08)
The disclosure features amino lipids and compositions involving the same. Nanoparticle compositions include an amino lipid as well as additional lipids such as phospholipids, structural lipids, PEG lipids, or a combination thereof. Nanoparticle compositions further including therapeutic and/or prophylactic agents such as RNA are useful in the delivery of therapeutic and/or prophylactic agents to mammalian cells or organs to, for example, regulate polypeptide, protein, or gene expression.
(E4,Z9)-Tetradecadienal, a sex pheromone for three North American moth species in the genus Saturnia

The lepidopteran genus Saturnia has three representatives in North America, S. walterorum, S. mendocino, and S. albofasciata. (E4,Z9)-Tetradecadienal (E4,Z9-14:Aid) was identified as a sex pheromone component for all three species by combinations of coupled gas chromatography-electroantennogram detection (GC-EAD), GC-mass spectrometry (MS), and field trials. In field trials, all three species were strongly attracted to (E4,Z9-14:Ald) as a single component, Small amounts of (Z)-9-tetradecenal (Z9-14:Ald) also were found in extracts of all three species, but blends of this compound with E4,Z9-14:Aid were no more attractive to male moths than E4,Z9-14:Ald alone. Extracts of pheromone glands of female S. walterorum occasionally contained a third, trace compound eliciting responses from male antennae in GC-EAD experiments, but this compound was not identified. It is suggested that the three species can use the same, single component as a sex attractant because the flight period of S. albofasciata (fall) is different than that of the other two species (spring), whereas the geographic distributions of S. mendocino and S. walterorum overlap over only small portions of their ranges. Furthermore, the latter two species readily hybridize, so there may be minimal fitness cost to cross-attraction.
Bioisosteric approach to elucidation of binding of the acetate group of a moth sex pheromone component to its receptor

A number of analogs of (Z)-5-decenyl acetate, a pheromone component of the turnip moth, Agrotis segetum, in which the acetate group has been replaced by functional groups that may function as bioisosters, have been synthesized and tested using single-cell electrophysiology. The activities have been interpreted in terms of the molecular electrostatic potentials of the polar functional group as calculated by ab initio quantum mechanical calculations. It is concluded that both oxygens of the acetate group in (Z)-5-decenyl acetate contribute to the interactions between the pheromone component and its receptor. Furthermore, the results indicate that the crucial interaction between the carbonyl group and the receptor, which is most probably a hydrogen bonding interaction, takes place in a direction pointing away from the hydrocarbon chain of the pheromone component.
