N-(4-Acetyl-4,5-dihydro-5-methyl-5-phenyl-1,3,4-thiadiazol-2-yl)acetamide Chemical Properties,Uses,Production

Description

K858 (72926-24-0) is a selective mitotic kinesin Eg5 inhibitor (IC50 = 1.3 μM) which acts in an ATP-noncompetitive manner.1,2It is at least 150-fold more selective for Eg5 than other members of the kinesin superfamily. K-858 blocks centrosome separation, activates the spindle checkpoint and induces mitotic arrest accompanied by the formation of monopolar spindles. Displays no effect on microtubule polymerization. Selectively displays antiproliferative effects via induction of mitotic cell death in cancer cells over nontransformed cells.1

Uses

K 858 is a selective ATP-uncompetitive mitotic kinesin Eg5 inhibitor.

Definition

ChEBI: N-(4-acetyl-5-methyl-5-phenyl-1,3,4-thiadiazol-2-yl)acetamide is a member of benzenes.

in vivo

K858 (50, 150 mg/kg, p.o.) shows antitumor activity in an A2780 ovarian cancer xenograft model, also inhibits tumor grwoth in a HCT116 colon cancer xenograft model via 100 mg/kg twice a day orally for 5 days. K858 (100 mg/kg, p.o., qd ×5) displays no neurotoxic side effects in mice[1].

IC 50

Eg5: 1.3 μM (IC50)
