The present invention pertains generally to the field of therapeutic compounds. More specifically the present invention pertains to certain pyridyl-amino-pyrazine carbonitrile compounds that, inter alia, inhibit Checkpoint Kinase 1 (CHK1) kinase function. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit CHK1 kinase function, and in the treatment of diseases and conditions that are mediated by CHK1, that are ameliorated by the inhibition of CHK1 kinase function, etc., including proliferative conditions such as cancer, etc., optionally in combination with another agent, for example, (a) a DNA topoisomerase I or II inhibitor; (b) a DNA damaging agent; (c) an antimetabolite or thymidylate synthase (TS) inhibitor; (d) a microtubule targeted agent; and (e) ionizing radiation. ##STR00001##

A method comprising co-administering to a subject having cancer, suspected of having cancer, or at risk of developing cancer: a therapeutically effective amount of at least one compound (a) selected from (a)(i) a nitroalkene fatty acid, (a)(ii) an unsaturated fatty acid having an electron withdrawing group, a leaving group, and a carbon-carbon double bond disposed between the electron withdrawing group and the leaving group, (a)(iii) a thiolated nitro fatty acid, or (a)(iv) a dicarboxylic acid compound containing an electron withdrawing group; and a therapeutically effective amount of at least one anti-neoplastic agent (b), wherein the cancer is a cancer with hereditary etiology of defects in DNA repair genes, a cancer with a high rate of spontaneous genomic instability, a cancer that responds well to DNA damaging agent(s), or a cancer that responds well to a combination of DNA damaging agent(s) with immunotherapy.

Disclosed herein are multifunctional nanoparticle compositions. The compositions can be useful for the treatment of cancer by enhancing the anti-tumor effectiveness of radiation directed to a tissue, cell or a tumor and the methods of use thereof. The multifunctional nanoparticle composition comprises a metal oxide nanoparticle core; a functional coating on the surface of the metal oxide nanoparticle core; and a matrix carrier in which the coated nanoparticle is embedded.

This document provides materials and methods for treating cancer (e.g., PD-L1.sup.+ cancers). For example, methods and materials for using compositions (e.g., compositions containing a small bioactive S249/T252 phospho-mimicking polypeptide of an RB polypeptide) to reduce PD-L1 expression within cancer cells are provided. In addition, methods and materials for using compositions (e.g., compositions containing a small bioactive S249/T252 phospho-mimicking polypeptide of an RB polypeptide) in combination with other cancer treatment methods or agents to increase the effectiveness exhibited against the cancer within a mammal (e.g., a human) are provided.

The present disclosure provides a heavy atom carrier and a method of treating cancer using the heavy atom carriers in conjunction with monochromatic X-ray. The heavy atom carriers are halogen-containing heavy atom carriers.

Described herein are methods for reducing or maintaining the size of a tumor in a subject, where the method involves exposing the tumor to ionizing radiation and administering to the subject a modified hyaluronan or a pharmaceutically acceptable salt or ester. The use of the modified hyaluronan enhances or potentiates the effect of ionizing radiation used in cancer treatment. Additionally, the methods described herein prevent or reduces tumor regrowth in the subject after exposing the tumor to ionizing radiation and administration of the modified hyaluronan to the subject.

There is provided with a method of treating cancer. A set of administration of a compound represented by General Formula (I) or a pharmaceutically acceptable salt thereof to a patient, at a dose such that 8 mg/kg or less of the compound represented by General Formula (I) is administered, and irradiation to the patient immediately following the administration is repeated. A total dosage of the irradiation to a cancer is 10 Gy or more.

The invention provides methods of treating metastatic or unresectable pancreatic cancer through the administration of a combination of an immune modulator and radiation therapy.

A method of treating a patient with a tumor, and kits (200) for such treatment. The method includes administering, to the patient, a substance (204) which activates cytoplasmatic sensors for intracellular pathogen in the tumor and treating the tumor with intra-tumoral alpha-emitter radiotherapy within two weeks of administering the substance which activates cytoplasmatic sensors for intracellular pathogen in the tumor.

Provided is an antibody that recognizes and binds to carbonic anhydrase or antigen-binding fragment, a nucleic acid molecule coding for the antibody or antigen-binding fragment, a vector carrying the nucleic acid molecule, a host cell including the nucleic acid molecule or the vector, and use of the antibody or antigen-binding fragment thereof in the alleviation, prevention, treatment or diagnosis of solid cancers.
