Piperidinecarboxamides with potential CNS and cardiovascular properties.
Several 1- and 2-(2-phenylethyl)piperidinecarboxamides were prepared and subjected to preliminary pharmacological studies. Moderate to strong activity by several compounds was observed in modified dopa potentiation tests in mice.
Synthesis and biological activity of quinolyl acetic acid derivatives.
Abstract Derivatives of 6-chloro-4-phenyl-3-carboxymethyl-2- quinolone and 6-chloro-4-phenyl-2,3-substituted quinolines were prepared and evaluated as CNS depressants and as antibacterial agents. The compounds had no CNS activity. The quinolyl acetamides exhibited antibacterial activity against Gram-positive bacteria.
Direct conversion pulsed UWB transceiver architecture
Ultra-wideband (UWB) communication is an emerging wireless technology that promises high data rates over short distances and precise locationing. The large available bandwidth and the constraint of a maximum power spectral density drives a unique set of system challenges. This paper addresses these challenges using two UWB transceivers and a discrete prototype platform.
