  • Patent number: 10730891
    Abstract: The present invention relates to a compound (L) for selective determination of free cysteine and a process for the preparation thereof. wherein R1 is selected from benzene, toluene, naphthalene and pyrene.
    Type: Grant
    Filed: July 29, 2016
    Date of Patent: August 4, 2020
    Assignee: COUNCIL OF SCIENTIFIC & INDUSTRIAL RESEARCH

  • Publication number: 20190382454
    Abstract: A modified peptide AT-01 has been synthesized from the microbiomic secretory protein MPT63 of Mycobacterium tuberculosis. This peptide (about 30 amino acids) contains a portion of the immunogenic region of MPT63 (131 amino acids). It has been found to stabilize SMAR1 (Scaffold Matrix Attachment Region Binding Protein 1), a tumor suppressor protein which is well characterized as anti-cancer. AT-01 was modified further to generate 6 new, independent peptides. Among the peptides AT-01 C and AT-01 D were found to be more effective than the other peptides. AT-01 D also attenuated cell migration of MDA-MB231 cells which supports the anti-metastatic activity. Inhibition of the cell growth from the Colony Formation Assays too supported its anticancer activity. It does not cause toxicity to the cells at high doses which demonstrates great potential value as a safe and effective cancer therapy.

  • Patent number: 8420100
    Abstract: Chimeric tumor suppressor activating peptides derived from matrix attachment region binding protein (MARBP) SMARI unique in their sequence comprising a arginine rich motif flanked by serine residues wherein from the stretch of four consecutive serine residues the first serine residue gets phosphorylated by the protein kinase C family of serine threonine kinases being indispensable for its functionality, the phosphorylation being directly correlated to the phosphorylation of p53 at serine 15 residue thereby stabilizing it, wherein the peptide activates p53 by modifying it post translationally which allow phosphorylation and translocation of p53 to the nucleus.
