Background:

GI50:< 0.1 nM for MCF-7 and MDA 468 cancer cell lines

GW 610 is a potent antiproliferative agent with tyrosine kinase inhibitory properties.

Tyrosine kinases are important mediators of the signaling cascade, having critical roles in various biological processes such as growth, differentiation, metabolism as well as apoptosis in response to both internal and external stimuli.

In vitro: GW 610 was evaluated in vitro in four human cancer cell lines, and GW 610 was observed to display potent antiproliferative activity exquisitely (GI50< 0.1 nM for both MCF-7 and MDA 468). Moreover, selective and potent activity was observed in the NCI 60 human cancer cell line panel as well. Structure-activity relationships (SARs) indicated that GW 610 exhibited a pinnacle of potent activity, with most structural variations with a deactivating in-vitro effect. Mechanistically, this noval compound contrasting with the previously reported 2-(4-aminophenyl)benzothiazoles, GW 610 was not dependent on induction of CYP1A1 expression for antitumor activity. An additional observation was that CYP1A1 protein was also expressed in MCF-7 and MDA 468 cells exposed to GW 610’s inactive analogues [1].

In vivo: Currently, there is no animal in vivo data reported.

Clinical trial: Up to now, GW 610 is still in the preclinical development stage.
