In Vitro	LB42708 induces cell death despite K-ras prenylation. Growth inhibition by LB42708 is accompanied by G1 and G2/M cell cycle arrests in H-ras and K-ras-transformed RIE cells, respectively. LB42708 induces the upregulation of p21(CIP1/WAF1) and RhoB above the basal level that leads to the cell cycle arrest and to distinct morphological alterations of ras-transformed rat intestinal epithelial (RIE) cells[2].
