  • Process for producing dihalopyridines
    Patent number: 8293918
    Abstract: Disclosed herein an improved process for producing 2,3-dihalopyridine with high purity at industrial scale with minimum effluent.
    Type: Grant
    Filed: December 18, 2009
    Date of Patent: October 23, 2012
    Assignee: Jubilant Organosys Limited
    Inventors: Gelebith H. Modi, Anil Kumar Tyagi, Ashutosh Agarwal, Hem Chandra, Nikhilesh Chandra Bhardwaj, Pradeep Kumar Verma
  • Mutants of and process thereof
    Patent number: 7943361
    Abstract: The present invention provides mutant Mycobacterium strains harboring a modified tyrosine phosphatase gene (mptpA or mptpB) wherein the mutant Mycobacterium strain is incapable of expressing the active tyrosine phosphatase. The invention provides a method for developing the said mutant strain from either Mycobacterium tuberculosis or Mycobacterium bovis. The mptpA or mptpB gene may be modified by replacing the internal sequences with an antibiotic resistance marker gene, which disrupts the expression of the active gene. The invention further provides a recombinant vector comprising the modified mptpA or mptpB which may be used to develop the mutant strains of mycobacteria. The invention provides a method to assess the role of tyrosine phosphatases MptpA and MptpB in the virulence and pathogenesis of Mycobacterium which can be used as potential targets for developing anti-tubercular drug.
