  • Patent number: 9029553
    Abstract: The present invention provides compounds of general formula A useful as potential anticancer agents against human cancer cell lines and apoptosis inducers. The present invention further provides a process for the preparation of 2-anilino nicotinyl linked 2-amino benzothiazole conjugates of general formula (A), wherein R1?H or Cl; R2?H, OCH3 or F; R3?H, OCH3, F or Cl; R4?H, OCH3 or F and X?OCH3, F or N02.
    Type: Grant
    Filed: March 30, 2011
    Date of Patent: May 12, 2015
    Assignee: Council of Scientific & Industrial Research
    Inventors: Ahmed Kamal, Yellamelli Valli Venkata Srikanth, Mohammed Naseer Ahmed Khan, Mohammed Ashraf, Irum Sehar, Gousia Chashoo, Parduman Raj Sharma, Abid Hamid Dar, Bhushan Shashi, Shashank Kumar Singh, Dilip Manikrao Mondhe, Ajit Kumar Saxena
  • Patent number: 8609858
    Abstract: The present invention relates to novel spiro derivatives of parthenin prepared by the dipolar cycloaddition of various dipoles viz, benzonitrile oxides, nitrones, azides, nitrile ylide diazoalkane, nitrile imide, ozone, azomethine imides, azomethine ylides etc. with exocyclic double bond of C ring (?-methylene-?-butyrolactone). Representative compounds have been screened for their anticancer activity against different cancer cell lines. ICs0 value of these analogues varies between 4.3 ?M to 93 ?M. A mechanistic correlation of their anticancer activity has been described. The results of the cytotoxicity test of the compounds studies indicated that the ?,?-unsaturated ketonic moiety in parthenin plays an important role in the maintenance of the high level of cytotoxicity.

  • Publication number: 20090298938
    Abstract: The present invention relates to use of compounds of general formula 1 for anticancerous activity, wherein the said compound being derived semi-synthetically from natural triterpenoic acids known as boswellic acids by the induction of apoptosis thereof cytotoxicity and anti-cancer activity displayed by semi-synthetic analogues of natural triterpenes, known as Boswellic acids. These compounds may be used for the treatment of cancer, alone or in combination with pharmaceutically acceptable or other carriers, displaying cytotoxicity and anti-cancer activity for colon, prostrate, liver, breast, central nervous system (CNS), leukemia and malignancy of other tissues, including ascites and solid tumors. The cancer cell death is mediated by induction of apoptosis and inhibition of cell proliferation at specific doses.

  • Patent number: 7489483
    Abstract: A system for sensing short circuits and open circuits prior to operation of a motor (i.e., while the motor is in a static state), thereby sparing the electrical system from destructive effects of these electrical problems. In addition, the system may detect a short circuit during operation of the motor (i.e., while the motor is in a dynamic state). Still yet, the system may detect an open circuit at the motor. The motor may be any electromechanical motor, such as a direct current (DC) motor, used in a vehicle or otherwise for controlling motion of a mechanical device.
