Based on 4 publication(s) in Google Scholar
FR900359 is a depsipeptide selective inhibitor of Gαq/11/14 in mammalia, can inhibits ERK pathway. FR900359 suppresses the proliferation of melanoma cells and decreases of blood pressure. FR900359 also protected against airway hyperreactivity in murine models of allergen sensitization in Ovalbumin, low endotoxin (HY-W250978A)-induced sensitization model of asthma. FR900359 can be used for cancer and cardiovascular disease research.

Biological Activity
FR900359 (1.0 μM, 1 hours) inhibits Gαq, Gα11 and Gα /14, but not Gα16 or any other mammalian Gα isoform in HEK293 cells[1].
FR900359 (0-10 μM, 24 hours) effectively reduces growth of B16 cells and suppressed cell proliferation and inhibits migration in a concentration-dependent manner[1].
FR900359 (10 nM, 72 hours) induces G1 cell cycle arrest in melanoma cells with Gq tone and forces melanoma cells (B16 cells) into differentiation [1].
FR900359 (1.0 μM, 5 min) interdicts the activation of extracellular signal-regulated kinases 1 and 2 (ERK1/2) that be largely Gq-mediated28[1].
FR900359 (1 μM, 24 hours) significantly induces more 92.1 cells undergoing apoptosis compared to untreated [3].
FR900359 (30 nM, 60 min) induces dose-dependent relaxation of murine, porcine, and human airways ex vivo[4].

Incubation Time:72 hours
-
Result:Induced G1 cell cycle arrest in melanoma cells with Gq tone.
Treated cells appeared flattened, rather dark, and packed with melanin vesicles, attributes consistent with the adoption of a more differentiated state.
Made melanocyte differentiation marker gp100 was upregulated considerably on FR treatment.

WT mice were injected with AAV2/9-E-SARE-ERT2-CreERT2-PEST and AAV2/9-CAG-FLEX-H3R-EGFP in the PVT. PVTHFD neurons were labeled with tamoxifen injection-paired HFD supply and EGFP-positive neurons were patched during electrophysiological assays. Representative firing curves of PVTHFD neurons after 100-pA depolarizing current injection (left), and the firing frequency with 0–100-pA depolarizing current injection (right) before and at 20 min FR900359 (10 μM, n = 10 cells) perfusion. The phosphorylation levels of the downstream proteins were determined by western blotting and shown in the lower right corner.

HDC-CreERT2 mice were injected with AAV2/9-CAG-FLEX-mCherry (AAV-FLEX-mCherry) or AAV2/9-CAG-FLEX-oChIEF-mCherry (AAV-FLEX-oChIEFmCherry) in the TMN. An optical fiber and a cannula were implanted in the PVT. Mice were exposed to blue (λ = 473 nm) or yellow (λ = 598 nm) light as indicated. Mice underwent HFD normal feeding test. Rhosin (10 μM), FR900359 (10 μM), or Barbadin (30 μM) diluted in saline was injected via the cannula before the test. n = 6 male mice in oChIEF + yellow light + saline group; 5 male mice in mCherry + blue light + saline group; 9 male mice in oChIEF + blue light+ saline group; 8 male mice in oChIEF + blue light + Rhosin group; 7 male mice in oChIEF + blue light + FR900359 group; 6 male mice in oChIEF + blue light + Barbadin group. blue light + FR900359 (1 μM).
