Abstract:

Systems, methods and apparatus of a secure RFID record are described herein. In one aspect, an apparatus of a RFID wristband comprises three layers: the top layer is a wristband, the middle layer is one RFID tag comprising one RFID chip and one tag antenna covering the wide area of the wristband, the bottom layer is made by anti-irritation materials. In another aspect, an apparatus of a RFID wristband comprises three layers: the top layer is a wristband, the middle layer has two RFID tags, each of which comprises one RFID chip and one tag antenna; the bottom layer is made by anti-irritation materials. In another aspect, a RFID system for secure communication comprises: a tag with at least two memory areas for storing an unique identifier and encoded data, respectively; a reader with at least three functions: key search, decoding process and encoding process; the unique identifier is associated with a key while the key is stored on the reader or a server connected to the reader.

International Classification:

A61K038/12

US Classification:

514/009000, 530/317000

Abstract:

The cyclic pentapeptide cyclo(-Arg-Gly-Asp-D-Phe-Lys-) is a highly potent and selective inhibitor for the integrin. A related compound, cyclo(-Arg-Gly-Asp-D-Phe-Val-), is a promising anticancer drug candidate; it has been found to inhibit angiogenesis and induce apoptosis in vascular cells. We have developed a synthesis of arginine containing cyclic peptides using the cyclizcation reagent 1-propanephosphonic acid cyclic anhydride (T3P) and the guanidine protecting group, 2,2,5,7,8-pentamethylchroman-6-sulfonyl (Pbf). This improved synthesis is environmentally friendly and is generally applicable to the synthesis of other cyclic peptides.
