Title: N-substituted oligomers and methods for their synthesis, e.g. polyglycine bearing nucleic acid bases
Inventor: RONALD N ZUCKERMANN
IPC: C07K1/08
Filed: 2003-02-27
Abstract: Poly N-substituted Glycines (poly NSGs), wherein the substituents bear purine or pyrimidine bases (R<9>) every second glycine: <CHEM> In addition, a solid phase method for the synthesis of N-substituted oligomers of more general structures is disclosed.The poly NSGs obtainable by this method can have a wide variety of side-chain substituents. Each N-substituted glycine monomer is assembled from two "sub-monomers" directly on the solid support. Each cycle of monomer addition consists of two steps: (1) acylation of a secondary amine bound to the support with an acylating agent comprising a leaving group capable of nucleophilic displacement by -NH2, such as a haloacetic acid, and (2) introduction of the side-chain by nucleophilic displacement of the leaving group, such as halogen (as a resin-bound  alpha -haloacetamide) with a sufficient amount of a second sub-monomer comprising an -NH2 group, such as a primary amine, alkoxyamine, semicarbazide, acyl hydrazide, carbazate or the like. Repetition of the two step cycle of acylation and displacement gives the desired oligomers. The efficient synthesis of a wide variety of oligomeric NSGs using the automated synthesis technology of the present method makes these oligomers attractive candidates for the generation and rapid screening of diverse peptidomimetic libraries. The oligomers of the invention, such as N-substituted glycines (i.e. poly NSGs) disclosed here provide a new class of peptide-like compounds not found in nature, but which are synthetically accessible and have been shown to possess significant biological activity and proteolytic stability.

Abstract: Unlimited energy for alternators, engines and pumps. Looking for the Wheel 2 that will be able to start an era of development, welfare, friendship among people, we thought of a self-rotating device with internal power produced by a stretched spring between the tyre and the long lever arm with fulcrum on the beam of the central loop, whose short arm turns back on the tyre TWISTS the long arm's push and takes it back, towards the first one. Synchrony among sections or the other concentric wheel (with tie bar instead of tyre) is assured by a rope or dragging hooks. The inventor SERI RANIERO, via CESI 3, Macerata, 62030, Italy, proposes the realisation of silent generators and CLAIMS as follows: 1) each self-rotating device with a stretched spring or a jack or another elastic band between tyre and pole-lever with reactivity retorion. IMPORTANT: for consequent mass migrations we need to receive from the UN, the Vatican and the US more discipline and spirituality and it is necessary to give a salary after the agricultural gold and the industrial dollar.
