Disclosed are agents that inhibit histone deacetylase. More specifically, the present invention relates to novel hydroxamic acid derivatives or pharmaceutically acceptable salts thereof for anticancer agents or other therapeutic agents based on their histone deacetylase inhibitory activity.

The present invention relates to a method of treating cancer in a subject in need thereof, by administering to a subject in need thereof a first amount of a histone deacetylase (HDAC) inhibitor or a pharmaceutically acceptable salt or hydrate thereof, in a first treatment procedure, and a second amount of an anti-cancer agent in a second treatment procedure. The first and second amounts together comprise a therapeutically effective amount. The effect of the HDAC inhibitor and the anti-cancer agent may be additive or synergistic.

The present invention provides for the use of a dimeric phthalide compound, the dimeric phthalide compound has broad anti-tumor activity, can directly inhibit the proliferation of tumor cells and induce cell death, but also indirectly inhibit the development of tumors by suppressing neovascularization. And further, the dimeric phthalide compound can be used alone or in combination to treat cancer, as well as in combination with chemotherapeutics to increase the efficacy of chemotherapeutics and decrease the toxicity of chemotherapeutics.

The present invention relates to the treatment of a mammal with a pharmaceutical composition comprising an H2-blocker, at least one anti-inflammatory agent, a cytotoxic agent and, optionally, levamisole, a retinoid, an NFkB inhibitor, a redox quinone, an agent that enhances the intracellular accumulation of NADH+H+, a poly-alcohol, an inhibitor of pro-angiogenic growth factor(s) and an MMP inhibitor, such pharmaceutical composition allowing for the enhanced therapy and / or prevention of neoplastic diseases and disorders.

The present invention relates to combination therapy for cancer with a WT1 peptide vaccine and temozolomide.

The 121-amino acid isoform of vascular endothelial growth factor (VEGF121) is linked by a flexible G4S tether to a cytotoxic molecule such as toxin gelonin or granzyme B and expressed as a soluble fusion protein. The VEGF121, fusion protein exhibits significant anti-tumor vascular-ablative effects that inhibit the growth of primary tumors and inhibit metastatic spread and vascularization of metastases. The VEGF121 fusion protein also target osteoclast precursor cells in vivo and inhibits osteoclastogenesis.

A halogenated dideoxy sugar derivative, having the following general structure I wherein X is halogen,R1 and R2 are H or Br; R3 and R4 are OH or OAc. The compounds 1-14 of the current invention has strong inhibition effect on human nasopharyngeal cancer CNE-2Z cells, human lung cancer A549 cells. human colon cancer HT-29 cells, human liver cancer Bel-7402 cells, human rectum cancer cells HCE 8693, human stomach cancer BGC-803 cells, human esophagus cancer CaEs-17 cells, human breast cancer cells MCF-7, human ovarian cancer cells A2780, pancreatic cancer cells PC-3, human bladder cells EJ, human brain glia cells TG-905, human leukemia cells K562, human melanoma M 14 cells and human anaplastic thyroid carcinoma TA-K cells. They can be used to prepare anti-tumor medicament and have significant clinic value.

The disclosure relates to compositions and methods for treatment, such as inducing regression or inhibiting growth, of tumors in a patient such as a human. Use of gemcitabine, including in self-emulsifying orally administered dosage forms for these purposes is described. Gemcitabine is orally administered in a metronomic manner, which involves repeatedly administering a therapeutic amount of gemcitabine, being a fraction of the maximum tolerated dose, over an extended period of time, preferably on a non-interrupted schedule of weeks, months, or indefinitely.

The present invention relates to integrin ligand modified long circulation liposome carrying anticarcinogen for injection, and is especially one kind of injected anticarcinogen carrying targeting liposome administration system. The efficient administration system is obtained through modifying the surface of liposome simultaneously with both polyethylene glycol and integrin containing arginine-glycine-asparagic acid sequence or RGD analogue.

The invention belongs to the biology technical field, relating an antineoplastic agent taking IL-23 gene or a cell introduced to the IL-23 gene as effective ingredient. The invention comprises the antineoplastic agent taking the following substances as the effective ingredient: a virus representing the IL-23 gene or non-virus carrier, a tumor cell introduced the IL-23 gene losing fission ability and an immune cell introduced the IL-23 gene. The antineolastic agent of the invention can be used independently or be combined with the treatment methods of operation, actinotheraphy and medical treatment for improving the cell immune response of organism, thereby achieving the aim of decreasing tumor volume, preventing transfer and preventing the recurrence of the tumor.

Provided is an antitumor agent targeting SIRPα, which inhibits binding between CD47 and SIRPα, the antitumor agent being more effective. The present invention also provides an antitumor agent capable of more effectively exhibiting an antitumor effect when used in combination with an immune checkpoint inhibitor or an antibody drug. The antitumor agent includes as an active ingredient a substance that molecularly targets an IgV domain, which is an extracellular domain of SIRPα. The antitumor agent of the present invention, including as an active ingredient a substance that molecularly targets an IgV domain of SIRPα protein, activates M1-type macrophages, which have cytotoxicity to cancer cells, and immunocompetent cells to provide an effective antitumor effect. Further, the antitumor agent can effectively exhibit an antitumor action not only on cancer cells expressing SIRPα on a cell surface but also on cancer cells not expressing the SIRPα when used in combination with, for example, an immune checkpoint inhibitor and / or an antibody drug that specifically reacts with a cancer antigen and has ADCC and ADCP activities.
