  • Patent number: 6475791
    Abstract: Methods disclosed herein capitalize on the ability of DNA Structure Specific Recognition Proteins (SSRPs) to bind to genomic lesions formed by chemotherapeutic agents, particularly cisplatin-type agents. Methods are provided for predicting whether an agent that damages DNA will also be cytotoxic, and for predicting whether particular eukaryotic cells will be susceptible to killing by a genotoxic drug. A screening method is provided for identifying new genotoxic drugs that produce SSRP-recognized lesions in DNA. Methods also are provided for sensitizing particular eukaryotic cells to killing by chemotherapeutic agents, particularly cisplatin-type drugs.
    Type: Grant
    Filed: June 2, 1997
    Date of Patent: November 5, 2002
    Assignee: Massachusetts Institute of Technology
    Inventors: Stephen J. Lippard, John M. Essigmann, Brian A. Donahue, Jeffrey H. Toney, Suzanne L. Bruhn, Pieter M. Pil, Steven J. Brown, Patti J. Kellett
  • Patent number: 5762647
    Abstract: A method of laundering soiled fabrics comprises contacting the fabrics in an aqueous laundering solution with a granular detergent composition comprising at least about 1% by weight of a surfactant, at least about 1% by weight of a builder, from about 6% to about 9% by weight of a particulate foam control agent, from about 1% to about 5% by weight of bleach activator, from about 0.3% to about 7% by weight of a peroxygen bleaching agent and from about 0.05% to about 0.2% by weight of a cellulase enzyme, wherein the detergent composition produces the low level of foam required for optimal cleaning in washing machines employing a low water wash process.

  • Patent number: 5670621
    Abstract: DNA structure specific recognition protein of eukaryotic origin and DNA encoding such a factor, as well as probes specific for DNA structure specific recognition protein or DNA encoding it and methods of detecting DNA structure specific recognition protein in eukaryotic cells. In particular, a mammalian cellular factor that selectively recognizes and binds DNA damaged or modified by a drug (the anticancer drug, cis-diamminedichloroplatinum (II) or cisplatin) has been identified.

  • Patent number: 5595967
    Abstract: Improved detergent compositions, especially granular detergents, comprising bleach activators which form multiperacids, especially specific monoquaternary substituted bis(peroxycarbonic) acids, upon perhydrolysis are provided.
    Type: Grant

  • Patent number: 5576282
    Abstract: Bleach boosters comprising zwitterionic imines and anionic imine polyions having a net negative charge are disclosed. The bleach boosters increase bleaching effectiveness in lower temperature solutions and demonstrate superior color safety profiles. The bleach boosters are ideally suited for inclusion into bleaching compositions including those with detersive surfactants and enzymes. Also provided is a laundry additive product including zwitterionic imines and anionic imine polyions with a net negative charge as bleach boosters. A method for laundering a fabric employing the bleach boosters of the present invention is also disclosed.

  • Patent number: 5415807
    Abstract: Anionic sulfonated poly-ethoxy/propoxy, especially modified isethionate, end-capped esters useful as soil release agents in detergent compositions are presented. The terephthalate esters are homogeneously integrated with one or more crystallization-reducing stabilizers.
