Galvestine-1 is a potent small-molecule inhibitor of monogalactosyldiacylglycerol (MGDG) synthase that competitively binds to the diacylglycerol substrate site with an IC50 of 10 μM. This bioactive compound demonstrates excellent plant mobility, being efficiently absorbed through roots and systemically distributed via xylem transport to mesophyll tissues. In Arabidopsis thaliana, Galvestine-1 treatment leads to significant reduction of MGDG content and disrupts chloroplast development, likely through impairment of thylakoid membrane biogenesis. These unique properties establish Galvestine-1 as a valuable chemical tool for investigating MGDG-dependent processes and studying lipid homeostasis mechanisms in plants.

IODVA1 is a small molecule with cellular inhibitory activity against several transformed cell lines including Ras-driven cells, targets Rac activation and signaling instead of Ras; IODVA1 inhibits ST8814 cell proliferation with GI50 of 1 uM, similar results were observed with MCF7, MDA-MB-231, and T47D cells with estimated GI50s <1 uM. IODVA1 significantly decreases number of colonies of the breast cancer cells in soft agar at 1 and 3 uM. IODVA1 probably does not bind Ras and that its mechanism of action is likely Ras-independent, inhibits lamellipodia and circular dorsal ruffle (CDR) formation in MDA-MB-231 cells and decreases Rac activation. IODVA1 inhibits Rac activation and downstream signaling leading to inhibition of lamellipodia and CDR formation; IODVA1 inhibits cell-substratum and cell-cell interactions, does not target kinases, and reduces tumor burden of solid tumors in vivo.
