    摘要: A transgenic rodent that constitutively expresses a ras protein in at least one tissue, is p21 null in at least one chromosome, and exhibits enhanced and accelerated ras-dependent tumorigenesis, together with methods for using said rodent, or cells derived thereof, for screening compounds or treatments for antitumor activity. In preferred embodiments, the rodent is a transgenic mouse that expresses a human ras oncogene operably linked to human regulatory sequences, and the cells of the mouse have at least one copy of a p21WAF1/ClP1transgene, whereby the mouse constitutively expresses a ras oncogene, and has decreased expression of p21. The rodents of the invention are useful in the study of ras-dependent oncogenesis and in the developments of treatments thereto.

    摘要: The subject invention pertains to the treatment of tumors and cancerous tissues and the prevention of tumorigenesis and malignant transformation through the modulation of JAK/STAT3 intracellular signaling. The subject invention concerns pharmaceutical compositions containing cucurbitacin I, or a pharmaceutically acceptable salt or analog thereof. Another aspect of the invention concerns methods of inhibiting the growth of a tumor by administering a cucurbitacin I, or a pharmaceutically acceptable salt or analog thereof, to a patient, wherein the tumor is characterized by the constitutive activation of the JAK/STAT3 intracellular signaling pathway. The present invention further pertains to methods of moderating the JAK and/or STAT3 signaling pathways in vitro or in vivo using cucurbitacin I, or a pharmaceutically acceptable salt or analog thereof. Another aspect of the present invention concerns a method for screening candidate compounds for JAK and/or STAT3 inhibition and anti-tumor activity.

    摘要: Disclosed herein is the use of HLM-008182, as well as its analogues formed via in-house synthesis, as a potent proteasome inhibitors. A new method was developed for HLM-008182 through a four-step protocol and the method was further optimized to a two step protocol. The synthesis in both protocols was regioselective with TiCl4. The reaction was highly efficient with microwave assisted heating and THF as solvent. The modification around the molecule HLM-008182 established primary SAR, indicating that the proteasome inhibition activity was a function of the 2-side chain.
