  • Patent number: 11952355
    Abstract: Provided are a method of preparing a malononitrile oxime ether compound and an intermediate compound. The malononitrile oxime ether compound has a structure as shown in formula (VII), wherein W is selected from aryl or heteroaryl. The preparation method comprises: reacting a first raw material with a second raw material in the presence of a first solvent and a catalyst to obtain the intermediate compound, wherein the first raw material has a structure as shown in formula (IV), and the second raw material has a structure as shown in formula (V); and subjecting the intermediate compound, and a dehydrant to a dehydration reaction in the present of a second solvent to obtain the malononitrile oxime ether compound. Furthermore, the malononitrile oxime ether compound is obtained through one-step dehydration reaction. using the preparation method, is advantageous for improving the yield of malononitrile oxime ethers and reducing the cost.

  • Publication number: 20190269768
    Abstract: A method for generating or expanding a population of T cells specific for a virus by a method comprising: stimulating T cells by culture in the presence of antigen presenting cells (APCs) presenting a peptide of the virus, wherein at least 10% of the media in which the cells are cultured is conditioned media obtained from a stimulation culture comprising T cells and APCs presenting a peptide of the virus. Also disclosed are methods for accelerating the rate of expansion of a virus-specific T cell population, and methods for treating or preventing diseases or disorders using the generated or expanded T cell population.

  • Patent number: 10052372
    Abstract: A method of treating a cancer in a subject is disclosed, comprising: (1) isolating T cells from a subject; generating or expanding a population of T cells specific for a virus by a method comprising: stimulating T cells by culture in the presence of antigen presenting cells (APCs) presenting a peptide of the virus, wherein 10 to 25% of the media in which the cells are cultured is conditioned media obtained from a stimulation culture comprising T cells and APCs presenting a peptide of the virus; and (3) administering the generated or expanded population of T cells to a subject. Also disclosed are methods for generating or expanding a population of T cells specific for a virus.

  • Publication number: 20170191034
    Abstract: The invention concerns a method of preparing a composition comprising stimulated immune system cells such as dendritic cells (DC) for use in inducing immune response of cytotoxic T lymphocytes against colorectal cancer. The dendritic cells are pulsed by contact with colorectal cancer stem cells (CSC) or their fragments thereof. These colorectal CSCs are produced by OSKM (Oct4, Sox2, Klf4 and c-Myc) induced reprogramming of differentiated colorectal cancer cells (CRC) which results in undifferentiated colorectal CSC-like cells. Both the CSC-like cells and the lysates of heat-shocked CSC-like cells could be used as an accessible source of tumour antigens for DC pulsing to induce specific immune responses against colorectal CSCs.

  • Publication number: 20110098346
    Abstract: There is presently provided a nucleic acid molecule comprising a glial-specific promoter; a coding sequence for a transgene; and a plurality of miRNA target sites. Each miRNA target site binds an miRNA that is down-regulated in .a glioma cell compared to a normal glial cell, and the glial-specific promoter and the plurality of miRNA target sites are both operably linked to the coding sequence for the transgene.
