GSK461364 Usage And Synthesis

Uses

GSK 461364 is a dose-dependant inhibitor of proliferating cancer cell lines as well as an apoptotic agent at higher dosage levels.

Definition

ChEBI: 5-[6-[(4-methyl-1-piperazinyl)methyl]-1-benzimidazolyl]-3-[(1R)-1-[2-(trifluoromethyl)phenyl]ethoxy]-2-thiophenecarboxamide is a member of (trifluoromethyl)benzenes.

Biological Activity

gsk461364 is a potent and reversible atp competitive plk1 inhibitor. polo-like kinases (plk) are a family of serine threonine kinases that are critical regulators of dna damage response and cell cycle progression.

in vitro

gsk461364 showed at least 390-fold greater selectivity for plk1 than for plk2 and plk3 and 1,000-fold greater than for 48 other kinases. the drug showed antiproliferative activity against multiple (>120) tumor cell lines and potently inhibited the proliferation of greater than 83% and 91% of these cell lines [1].

in vivo

intraperitoneal administration of gsk461364 caused regression or tumor growth delay in different xenograft models. in vivo suppression of plk1 by using gsk461364 resulted in mitotic arrest with aberrant mitotic figures consisting of monopolar or collapsed mitotic spindles [1].
