  • Patent number: 7183059
    Abstract: A method of generating a compound having at least one biological activity of a peptide. The method includes identifying a biologically active peptide, providing a first monomer which contains terminal reactive moieties and at least one functionalizable group, providing a second monomer which contains terminal reactive moieties and at least one functionalizable group, and reacting first and second monomer under stereo-and/or regiochemically controlled conditions to yield a compound in which the monomers are attached by way of terminal reactive moieties.

  • Publication number: 20020016010
    Abstract: The present invention provides a system for the production of chemical compounds and libraries of compounds that are complex, stereochemically and regioselectively pure, and may mimic the structural or functional properties of a peptide. The invention provides methods for producing collections of peptidomimetic compounds which, in one preferred embodiment, comprises (1) providing two diversifiable monomers containing terminal reactive moieties; (2) reacting the monomers under conditions that allow for the control of stereochemistry as well as chemoselectivity; and (3) generating diversifiable isolable compounds or libraries of compounds.

  • Patent number: 4449231
    Abstract: A test signal generator for pseudo-simulated non-intelligible speech. The generator comprises first and second ROM's controlled by first and second address counters driven by a single clock. The first ROM generates digital samples which when decoded produce a random signal having a gaussian amplitude distribution. The second ROM also generates digital samples which when decoded produce a modulating signal having a power spectrum substantially equal to that of the modulation envelope of speech and a wave shape that results in a gamma amplitude distribution of a gaussian amplitude distributed signal. Each cycle of the modulating signal has an identical wave shape but a randomly varying wave period.
