Abstract: a pharmaceutical composition for preventing, treating, or ameliorating one or more symptoms of a malignant tumor associated with EGFR mutation and/or K-RAS mutation is provided. The pharmaceutical composition includes a 4-anilinoquinazoline derivative having a formula (I) where A is iodine when m is 1 and n is zero, or A is albumin when m is an integral ranging from 1 to 7 and n is 1.

Abstract: EGFR mutation (T790M) and cancerous stemness have shown drug resistances in human non-small-cell lung cancer (NSCLC), thus development of novel drugs in overcoming drug resistances in the NSCLC therapy is highly desired. SP101 is a novel gefitinib derivative, which can bind the ATP-binding pocket of EGFR to inhibit its EGFR kinase activity. SP101 can reduce the drug resistances of EGFR mutation (T790M) and cancerous stemness in NSCLC. SP101 induced cancer cell death and apoptosis in the gefitinib-resistant EGFR mutation (T790M) H1975 cells. SP101 inhibited phosphorylated EGFR and its downstream Survivin proteins but conversely induced Caspase 3 activation for apoptosis induction. Moreover, SP101 could decrease Oct4 protein level and reduce Survivin proteins but conversely elicited active Caspase 3 in the xenograft human H1975 lung tumors in nude mice.

Abstract: A method for separating labeled cells and a use (of the labeled cells) thereof are provided. More specifically, a method for labeling cells using fluorescent magnetic nanodiamonds, and a method for separating the labeled cells using the labeling method by the fluorescent or magnetic properties of the nanodiamonds are provided.

Abstract: The present invention provides a carrier including a nanodiamond (ND) particle and a linker covalently bound to the ND particle, in which the linker is presented by the formula: —R1—O(R2)m-Q-. In addition, the present invention further provides a carrier having an active unit covalently bound to the linker, in which the active unit is a drug, a vitamin or a biological molecule.

Abstract: A use of a compound in obtaining cytoskeleton and cell elongation is disclosed, the compound is 7-chloro-6-piperidin-1-yl-quinoline-5,8-dione with a chemical formula of C14H13CIN2O2, is designated as PT-262. The PT-262 can induce cell elongation by stabilization of the F-actin and induction of the abnormal actin polymerization in cancer cells, further, the PT-262 possesses antitumor activity and can block survival pathway of the cancer cells, resulting in cancer cells apoptosis, and the PT-262 can induce growth arrest and inhibition of cell cycle. PT-262 stabilizes cancer cells cytoskeleton that results in an irreversible cell elongation, decreases the levels of cyclin B1 and phospho-cdc2 proteins, and inhibits the survival signal pathway of Ras-ERK proteins. The PT-262 also inhibits the mitochondrial membrane potential and induces the caspase-3 activation and apoptosis in the cancer cells.
