  • Characterization of the Biological Activity of a Potent Small Molecule Hec1 Inhibitor TAI-1
    Huang et al. Journal of Experimental & Clinical Cancer Research 2014, 33:6 http://www.jeccr.com/content/33/1/6 RESEARCH Open Access Characterization of the biological activity of a potent small molecule Hec1 inhibitor TAI-1 Lynn YL Huang1*, Ying-Shuan Lee2, Jiann-Jyh Huang2, Chia-chi Chang1, Jia-Ming Chang2, Shih-Hsien Chuang2, Kuo-Jang Kao1, Yung-Jen Tsai2, Pei-Yi Tsai2, Chia-Wei Liu2, Her-Sheng Lin2 and Johnson YN Lau1 Abstract Background: Hec1 (NDC80) is an integral part of the kinetochore and is overexpressed in a variety of human cancers, making it an attractive molecular target for the design of novel anticancer therapeutics. A highly potent first-in-class compound targeting Hec1, TAI-1, was identified and is characterized in this study to determine its potential as an anticancer agent for clinical utility. Methods: The in vitro potency, cancer cell specificity, synergy activity, and markers for response of TAI-1 were evaluated with cell lines. Mechanism of action was confirmed with western blotting and immunofluorescent staining. The in vivo potency of TAI-1 was evaluated in three xenograft models in mice. Preliminary toxicity was evaluated in mice. Specificity to the target was tested with a kinase panel. Cardiac safety was evaluated with hERG assay. Clinical correlation was performed with human gene database. Results: TAI-1 showed strong potency across a broad spectrum of tumor cells. TAI-1 disrupted Hec1-Nek2 protein interaction, led to Nek2 degradation, induced significant chromosomal misalignment in metaphase, and induced apoptotic cell death. TAI-1 was effective orally in in vivo animal models of triple negative breast cancer, colon cancer and liver cancer.

The module can simultaneously acquire and track multiple satellite constellations that include GPS, GLONASS, GALILEO, QZSS and SBAS. It features low power and small form factor. Besides, it can provide you with superior sensitivity and performance even in urban canyon and dense foliage environment. This module supports hybrid ephemeris prediction to achieve faster cold start. One is self-generated ephemeris prediction (called EASY) that is no need of both network assistance and host CPU’s intervention. This is valid for up to 3 days and updates automatically from time to time when GNSS module is powered on and satellites are available. The other is server-generated ephemeris prediction (called EPO) that gets from an internet server. This is valid for up to 14 days. Both ephemeris predictions are stored in the on-board flash memory and perform a cold start time less than 15 seconds. 2 Features MediaTek high sensitivity solution Support GPS, GLONASS, GALILEO and QZSS Capable of SBAS (WAAS, EGNOS, MSAS, GAGAN) Support 99-channel GNSS Low power consumption Fast TTFF at low signal level Built-in 12 multi-tone active interference canceller Free hybrid ephemeris prediction to achieve faster cold start Built-in data logger Up to 10 Hz update rate ±11ns high accuracy time pulse (1PPS) Indoor and outdoor multi-path detection and compensation Small form factor 16 x 12.2 x 2.2 mm SMD type with stamp holes; RoHS compliant ISO/TS 16949 quality control Support RTCM SC-104 Version-2.x 3 Application Personal positioning and navigation Automotive navigation Page 1/23 © 2014 LOCOSYS Technology Inc.
