  • Patent number: 8841285
    Abstract: Provided herein include compositions, all related stereoisomers as well as pharmaceutically acceptable salts provided as simplified analogs of pateamine A, in which the analogs generally are devoid of the C3-amino and C5-methyl groups, also referred to as desmethyl, desamino-pateamine A. Suitable analogs provide anticancer and antiproliferative effects in vivo and in vitro by a novel drugs mechanism of action described herein for pateamine A, including inhibition of eIF4A-dependent translation initiation. As with pateamine A, as described herein, suitable analogs cause cell cycle arrest or induce apoptosis in transformed cells. However, toxicity of such compounds to slow growing normal cells is low. In addition, such analogs, like pateamine A, target translation initiation factors and are useful as anticancer and antiproliferative agents in subjects in need thereof.

  • Patent number: 8666930
    Abstract: A string matching device extracts a string by shifting a start position from an input data stream, compares the extracted string with a sub-string included in a target string, and when a prefix of a target string is detected from the string extracted from the input data stream, it selects one of the strings output in the next stage based on the start position of the corresponding string and uses it to detect the sub-string. Also, the device can consecutively detect at least one target string from the input data stream by using a state transition process.
