How to use

In Vitro:

RG14620 inhibits colony formation (IC50=3 μM) and DNA synthesis (IC50=1 μM) by HER 14 cells, which are stimulated by 50 ng/mL EGF, in a dose-dependent manner. RG14620 also suppresses colony formation(IC50=4 μM) and DNA synthesis (IC50=1.25 μM) by EGF-stimulated MH-85 cells in a dose-dependent manner. The growth-inhibitory effect of RG14620 irreversible.

In Vivo:

RG14620, at a dose of 200 g/mouse/day inhibits H-85 tumor growth in nude mice. Mice show less cachexia and hypercalcemia, eat more food, and are more active than untreated MH-85 tumor-bearing animals.
