General description

A cell-permeable quinazoline-thione compound that acts as a potent, specific, and reversible inhibitor of the microtubule-stimulated ATPase activity of the mitotic motor, Eg5 (IC50 = 200 nM). Exhibits little effect on the ATPase activity of kinesin-1, -4, -7 and -10 and is ~100-fold more potent than Monastrol (Cat. No. 475879). Also inhibits bipolar spindle formation in both HeLa cells and in Xenopus egg extracts and induces cell cycle arrest (~1 µM). Shown to induce mitotic arrest and apoptosis and upregulate Hsp70 in human multiple myeloma cells.

Extravehicular activities, the backbone of manned space exploration programs, set astronauts into mild hypoxia. Unfortunately, microgravity aggravates threatening symptoms of hypoxia such as vision impairment and brain edema. Hypoxia-inducible factors (HIFs) sense cellular hypoxia and, subsequently, change the cells' expression

Chromosomal instability (CIN) is a hallmark of many cancers. Restricting the localization of centromeric histone H3 variant CENP-A to centromeres prevents CIN. CENP-A overexpression (OE) and mislocalization have been observed in cancers and correlate with poor prognosis; however, the molecular

During the entry process, the human papillomavirus (HPV) capsid is trafficked to the trans-Golgi network (TGN), whereupon it enters the nucleus during mitosis. We previously demonstrated that the minor capsid protein L2 assumes a transmembranous conformation in the TGN. Here
