  • Publication number: 20050163855
    Abstract: Provided is a method of preparing low-crystallinity oltipraz or amorphous oltipraz. The method includes: obtaining a mixed solution containing oltipraz and a water-soluble polymer or a water-insoluble polymer in a solvent, the solvent being an organic solvent or purified water; and solid-dispersing the oltipraz in the polymer. In the solid-dispersing, the mixed solution may be spray dried using a spray dryer or granulated using a fluid bed granulator.

  • Patent number: 6596534
    Abstract: A therapeutic agent based on a recombinant adenovirus which employs an osteocalcin promoter for the expression of thymidine kinase can be administered intravascularly to treat metastatic cancer, including osteosarcoma, breast cancer, prostate cancer, ocular melanoma or brain cancer. Systemic administration of this agent provides a preferred route over previous disclosure of local direct administration. The same therapeutic agent can be effectively employed in the treatment of benign conditions, including benign prostatic hypertrophy and arteriosclerosis.

  • Patent number: 6465020
    Abstract: This invention is concerned with the clinical investigation of the therapeutic effects of garlic extracts containing allicin, diallyl disulfide, and diallyl trisulfide. The intake of garlic or therapeutically active substances such as allicin from garlic, induces immunostimulation and these active substances possess strong antitumor effects including the apoptosis of tumors, including the programmed cell death of human prostatic and bladder tumor cells. This invention claims that garlic and/or garlic extracts possess very effective therapeutic substances useful not only to treat human prostate and bladder cancers to extend life span of patients, but also to suppress or prevent bladder and prostate gland cancers.

  • Publication number: 20020044978
    Abstract: This invention is concerned with clinical investigation of therapeutic effects of garlic extracts containing allicin, diallyl disulfide, and diallyl trisulfide. Because the intake of garlic or therapeutically active substance such as allicin from garlic, induces immunostimulation and possess strong antitumor effects concomitant with apoptosis of tumors that can in turn induces a programmed cell death of human prostatic and bladder tumor cells. This invention claims that garlic and/or garlic extracts possess very effective therapeutic substances not only to treat human prostate and bladder cancers to extend life span of patients, but also to suppress or prevent bladder and prostate gland cancers.

  • Patent number: 5772993
    Abstract: A recombinant adenovirus Ad-OC-TK was constructed, with cell specific gene expression, which contains osteocalcin (OC) promoter that drives the expression of herpes simplex virus thymidine kinase (TK); the addition of acyclovir (ACV), a pro-drug for the inhibition of cell proliferation, to Ad-OC-TK resulted in the induction of osteoblast-specific cell death in vitro. The Ad-OC-TK virus plus ACV treatment is highly selective in blocking the growth of both murine and human osteosarcoma cell lines in vitro and murine osteosarcoma in vivo.
