Abstract:
The present invention provides a novel bioactive substance having an antiangiogenic effect. The chemical compound represented by the formula (1) (wherein, R1 represents hydrogen atom, aldehyde group or a lower acyl group, R2 and R3 are the same as or different from each other and represent hydrogen atom or a lower alkoxy group or are combined to represent oxygen atom, R4 represents a lower alkyl group and R5 represents hydrogen atom or a lower alkyl group, provided that compounds in which R1 is aldehyde group, R2 and R3are different from each other and are hydrogen atom or methoxy group, R4 is ethyl group and R5 is hydrogen atom are excluded), a salt thereof or a hydrate thereof was isolated from the culture broth of genus Streptomyces and the structure thereof was analyzed.
Abstract:
An antitumor agent for combined use of a compound or pharmaceutically acceptable salt thereof represented by Formula (I) and a compound or pharmaceutically acceptable salt thereof represented by Formula (II) exhibits an excellent antitumor effect compared to cases where these are individually used, and exhibits antitumor effects against various cancer types: wherein R1 is azetidinyl and the like, R2 to R5 is a hydrogen atom or a halogen atom, R6 is C3-8 cycloalkyl and the like, R7 is a hydrogen atom and the like, and R8 is a halogen atom and the like.
Abstract:
Biomarkers are provided that are predictive of a subject's responsiveness to a therapy comprising lenvatinib or a pharmaceutically acceptable salt thereof (e.g., lenvatinib mesylate). The biomarkers, compositions, and methods described herein are useful in selecting appropriate treatment modalities for a subject having cancer (e.g., thyroid cancer, kidney cancer), suspected of having cancer, or at risk of developing cancer.
Abstract:
This invention provides a method for treating a subject having a tumor and a method for inhibiting angiogenesis in a subject, both comprising administering to the subject an effective amount of a composition of matter comprising the extracellular domain of a Notch receptor protein operably affixed to a half-life-increasing moiety. This invention also provides a composition of matter comprising the extracellular domain of Notch4 receptor protein operably affixed to a half-life-increasing moiety. This invention further provides an article of manufacture. Finally, this invention provides a replicable vector which encodes a polypeptide comprising the extracellular domain of a Notch receptor protein operably affixed to a half-life-increasing moiety, a host vector system which comprises such replicable vector and a method of producing such polypeptide.

Abstract:
The present invention creates a novel antiangiogenic agent and provides an antitumor agent which shows high safety as compared with conventional antitumor agents, has a sure effect and is able to be administered for a long period. That is, it provides an indole compound represented by the following formula (I), its pharmacologically acceptable salt or hydrates thereof. In the formula, R1 represents hydrogen atom, a halogen atom or cyano group; R2 and R3 are the same as or different from and each represents hydrogen atom, a C1-C4 lower alkyl group or a halogen atom; R4 represents hydrogen atom or a C1-C4 lower alkyl group; and the ring A represents cyanophenyl group, aminosulfonylphenyl group, aminopyridyl group, aminopyrimidyl group, a halopyridyl group or cyanothiophenyl group, provided that the case where all of R1, R2 and R3 are hydrogen atoms, where both R2 and R3 are hydrogen atoms or where the ring A is aminosulfonyl group and both R1 and R2 are halogen atoms is excluded. Further, when the ring A is cyanophenyl group, 2-amino-5-pyridyl group or a 2-halo-5-pyridyl group and R1 is cyano group or a halogen atom, at least one of R2 and R3 should not be a hydrogen atom.

Abstract:
The clock demodulator 25 continually demodulates the clock signal of the control CPU 7 transmitted from the clock modulator 10 of the center S. The terminal control CPU 23 performs processes such as transmission and reception of data with the demodulated clock signal as a reference clock. The time required to synchronize the clocks of the CPUs 7 and 23 is eliminated. Transmission and reception of data is executed quickly as soon as right of transmission is transferred to a terminal.
