    Article Title: Design, synthesis and biological evaluation of novel quinazoline-derived EGFR/HER-2 dual-target inhibitors bearing a heterocyclic-containing tail as potential anti-tumor agents.
    Article Snippet: A series of novel quinazoline-derived EGFR/HER-2 dual-target inhibitors were designed and synthesized by heterocyclic-containing tail approach.. The inhibitory activities against four human epidermal growth factor receptor (HER) isozymes (EGFR, HER-2, HER-3 and HER-4) of all new compounds so designed were investigated in vitro.. Compound 12k was found to be the most effective and rather selective dual-target inhibitor of EGFR and HER-2 with inhibitory constant (IC50) values of 6.15 and 9.78 nM, respectively, which was more potent than the clinical used agent Lapatinib (IC50 = 8.41 and 9.41 nM).

    Article Title: Discovery of N-(1,3,4-thiadiazol-2-yl)benzamide derivatives containing a 6,7-methoxyquinoline structure as novel EGFR/HER-2 dual-target inhibitors against cancer growth and angiogenesis.
    Article Snippet: Targeting EGFR and HER-2 is an essential direction for cancer treatment.. Here, a series of N-(1,3,4-thiadiazol-2yl)benzamide derivatives containing a 6,7-methoxyquinoline structure was designed and synthesized to serve as EGFR/HER-2 dual-target inhibitors.. The kinase assays verified that target compounds could inhibit the kinase activity of EGFR and HER-2 selectively.

    Kaplan-Meier analyses of PFS and OS time in stage I–IIB osteosarcoma patients. Significant differences in (A) PFS (P=0.033) and (B) OS (P=0.041) time were found between the high and low EGFR expression groups. Significant differences in (C) PFS (P=0.001) and (D) OS (P=0.006) time were found between the high and low HER-3 expression groups. Significant differences in (E) PFS (P=0.010) and (F) OS (P=0.015) time were found between the high and low HER-4 expression groups. HER, human epidermal growth factor receptor; PFS, progression-free survival; OS, overall survival.
