Publication number: 20200131140Abstract: The present disclosure provides improved methods for controlled cyclization of peptoid dimers to form N,N?-2,5-diketopiperazines (N,N?-2,5-DKPs) with significant selectivity. In at least some examples, selectivity is based on a serendipitous conglomeration of slow exchange of amide rotamers, steric repulsion from the degree of ?-substitution, and the geometric bulk of an amine nucleophile. By varying reaction conditions, the selectivity of the reaction and formation of a particular N,N?-2,5-DKP can be switched. The cyclization works in the presence of a variety of protection groups and diverse functionalities. The teachings herein provide techniques for synthesizing N,N?-2,5-DKPs that can be readily docked with drug candidates for shuttling across the blood brain barrier. This method provides a facile way to produce substituted DKPs containing groups ready for post-modification to include docking drug candidates.Type: ApplicationFiled: October 30, 2019Publication date: April 30, 2020Applicant: Triad National Security, LLCInventors: Robert F. Williams, Paul William Peterson, Robert David Gilbertson, Jurgen G. Schmidt, Charlie E. Strauss

Patent number: 10602521Abstract: A wireless network includes at least a pair of nodes that are configured to communicate with each other by transmitting and receiving one or more millimeter-wave beams through an obstruction and through unobstructed air. In accordance with an exemplary embodiment of the network, the nodes include small, phased-array antennas and transceivers, configured with radio electronics to mitigate the path loss through certain obstructions, such as walls, floors, barriers within buildings, and the attenuation from free-space path-loss, including moisture in air (humidity).
