  • Publication number: 20220002291
    Abstract: The present disclosure provides compounds of the formula (I) wherein these compounds contain a ligand which binds to one or more target proteins such as CDK4 or CDK6 and a ligand which binds to the machinery associated with the ubiquitinating protein machinery. Also provided herein are methods of using these compounds in compositions or methods of treating patients with these compounds for the treatment of a disease or disorders such as cancer.

  • Patent number: 5989849
    Abstract: Oligonucleotides are provided having a nucleotide sequence complementary to at least a portion of the mRNA transcript of the human c-kit gene. These "antisense" oligonucleotides are hybridizable to the c-kit mRNA transcript. Such oligonucleotides are useful in selectively inhibiting proliferation of erythroid cells, particularly in disorders characterized by an elevated hematocrit due to over-production of erythrocytes. The antisense oligomers also have activity agent hematologic neoplastic cells and are therefore suitable as bone marrow purging agents.

    Inventors: Alan M. Gewirtz, Bruno Calabretta
  • Patent number: 5817783
    Abstract: DR-nm23 protein is disclosed. A nucleotide sequence encoding the same and fragments thereof, recombinant expression vectors that comprise the nucleotide sequence, host cell comprising the recombinant expression vectors and methods of making DR-nm23 protein are disclosed. Oligonucleotide molecules comprising a nucleotide sequence complementary to a portion of the nucleotide sequence that encodes DR-nm23 and methods of using the same to inhibit DR-nm23 expression are disclosed. Isolated antibodies that bind to an epitope on DR-nm23 are disclosed. Methods of tracking the progress on chronic myelogenous leukemia and methods of detecting the onset of blast crisis phase in an individual with chronic myelogenous leukemia are disclosed.
    Type: Grant
    Filed: June 20, 1996
    Date of Patent: October 6, 1998
    Assignee: Thomas Jefferson University
    Inventors: Bruno Calabretta, Donatella Venturelli, Robert V. Martinez
  • Patent number: 5734039
    Abstract: Therapeutic combinations of two or more antisense oligonucleotides are provided. At least one first antisense oligonucleotide specific for a cytoplasmic oncogene or proto-oncogene and at least one second antisense oligonucleotide specific for a nuclear oncogene or proto-oncogene are combined for treatment of a neoplastic disease. The first antisense oligonucleotide may be specific for, e.g., a ras or raf gene, or an oncogene which codes for a protein tyrosine kinase. The nuclear gene-targeting antisense oligonucleotide preferably may be specific for a nuclear oncogene or proto-oncogene which encodes a transcriptional factor. The combined oligonucleotides have enhanced activity against neoplastic disease.

  • Patent number: 5652222
    Abstract: Leukemias characterized by the presence of the Philadelphia chromosome and the expression of the hybrid bcr-abl gene are treated with antisense oligonucleotides complementary to a target sequence of the bcr-abl mRNA transcript including the breakpoint junction. Individual chronic myelogoneous leukemia patients or Philadelphia chromosome-positive acute lymphocytic leukemia patients are treated by first sequencing the individual's bcr-abl breakpoint junction, and then administering antisense oligonucleotides complementary thereto. The oligonucleotides are designed to hybridize specifically to the bcr-abl breakpoint junction without substantial cross hybridization to untranslocated c-abl sequences. Treatment may comprise in vivo administration of antisense oligonucleotides, or ex vivo treatment such as bone marrow purging.

  • Patent number: 5427916
    Abstract: The effectiveness of selected antineoplastic agents may be determined in individual patients by comparing the level of expression of one or more selected growth-regulated genes in neoplastic cells taken from the patient before and shortly after the initiation of therapy. A decrement in expression is prognostic of eventual remission, while a lack of decrement indicates that remission is unlikely. The test may also be accomplished by comparing the level of expression of growth-regulated genes in neoplastic cells in culture before and after incubation of the cells with the selected antineoplastic agents.

  • Patent number: 5362631
    Abstract: A c-myb transfected cell line capable of producing a selected growth factor is provided. In a preferred embodiment, human glioblastoma cells are co-transfected with a first plasmid containing human c-myb DNA and second plasmid containing the gene encoding hygromycin resistance. Methods of producing selected growth factors employing cell line are also provided.

  • Patent number: 5098890
    Abstract: Oligonucleotides are provided having a nucleotide sequence complementary to at least a portion of the mRNA transcript of the human c-myb gene. These "antisense" oligonucleotides are hybridizable to the c-myb mRNA transcript. Such oligonucleotides are useful in treating hematologic neoplasms and in inducing immunosuppression. They are particularly useful as bone marrow purging agents.
