α-Melanocyte-stimulating hormone (α-MSH) is a 13-amino acid peptide hormone produced by post-translational processing of proopiomelanocortin (POMC) in the pituitary gland, as well as in keratinocytes, astrocytes, monocytes, and gastrointestinal cells.1It is an agonist of melanocortin receptor 3 (MC3R) and MC4R that induces cAMP production in Hepa cells expressing the human receptors (EC50s = 0.16 and 56 nM, respectively).2α-MSH (100 pM) reducesS. aureuscolony formation andC. albicansgerm tube formationin vitro.3It inhibits endotoxin-, ceramide-, TNF-α-, or okadaic acid-induced activation of NF-κB in U937 cells.1α-MSH reduces IL-6- or TNF-α-induced ear edema in mice.4It also prevents the development of adjuvant-induced arthritis in rats and increases survival in a mouse model of septic shock. Increased plasma levels of α-MSH are positively correlated with delayed disease progression and reduced death in patients with HIV.1 1.Catania, A., Airaghi, L., Colombo, G., et al.α-melanocyte-stimulating hormone in normal human physiology and disease statesTrends Endocrinol.

(±)10(11)-EDP ethanolamide is an ω-3 endocannabinoid epoxide and cannabinoid (CB) receptor agonist (EC50s = 0.43 and 22.5 nM for CB1 and CB2 receptors, respectively). It is produced though direct epoxygenation of docosahexaenoyl ethanolamide by cytochrome P450 (CYP) epoxygenases. 10,11-EDP epoxide (12.5 and 25 μM) reduces the viability of 143B metastatic osteosarcoma cells. It induces apoptosis and inhibits cell migration in a wound-healing assay in 143B, MG63, and HOS osteosarcoma cells. (±)10(11)-EDP ethanolamide also reduces tube formation by human umbilical vein endothelial cells (HUVECs) in a Matrigel assay.

(±)19(20)-EDP ethanolamide is an ω-3 endocannabinoid epoxide and cannabinoid (CB) receptor agonist (EC50s = 108 and 280 nM for CB1 and CB2, respectively). It is produced through direct epoxygenation of docosahexaenoyl ethanolamide by cytochrome P450 (CYP) epoxygenases. (±)19(20)-EDP ethanolamide (25 μM) reduces the viability of 143B metastatic osteosarcoma cells. It decreases the production of IL-6 and increases the production of IL-10 when used at concentrations ranging from 2.5 to 10 μM in BV-2 microglia stimulated by LPS and decreases LPS-induced cytotoxicity when used at concentrations ranging from 5 to 10 μM. It also decreases nitrite production when used at a concentration of 7.5 μM, an effect that can be partially reversed by the CB2 receptor antagonist AM630 and the PPARγ antagonist GW 9662 . (±)19(20)-EDP ethanolamide induces vasodilation of isolated preconstricted bovine coronary arteries (ED50 = 1.9 μM) and reduces tube formation by human microvascular endothelial cells (HMVECs) in a Matrigel assay.

KRH102053 is a HIF-1alpha inhibitor.

EHT-6706 is a novel microtubule-disrupting agent that targets the colchicine-binding site to inhibit tubulin polymerization. At low nM concentrations, EHT 6706 exhibits highly potent antiproliferative activity on more than 60 human tumor cell lines, even those described as being drug resistant. EHT 6706 also shows strong efficacy as a vascular-disrupting agent, since it prevents endothelial cell tube formation and disrupts pre-established vessels, changes the permeability of endothelial cell monolayers and inhibits endothelial cell migration. Genome-wide transcriptomic analysis of EHT 6706 effects on human endothelial cells shows that the antiangiogenic activity elicits gene deregulations of antiangiogenic pathways. These findings indicate that EHT 6706 is a promising tubulin-binding compound with potentially broad clinical antitumor efficacy.

MPT0B098 is a potent microtubule inhibitor through binding to the colchicine-binding site of tubulin. MPT0B098 is active against the growth of various human cancer cells, including chemoresistant cells with IC50 values ranging from 70 to 150 nmol L. MPT0B098 arrests cells in the G2–M phase and subsequently induces cell apoptosis. In addition, MPT0B098 effectively suppresses VEGF-induced cell migration and capillary-like tube formation of HUVECs. Distinguished from other microtubule inhibitors, MPT0B098 not only inhibited the expression levels of HIF-1α protein but also destabilized HIF-1α mRNA. The mechanism of causing unstable of HIF-1α mRNA by MPT0B098 is through decreasing RNA-binding protein, HuR, translocation from the nucleus to the cytoplasm. Notably, MPT0B098 effectively suppresses tumor growth and microvessel density of tumor specimens in vivo. Taken together, our results provide a novel mechanism of inhibiting HIF-1α of a microtubule inhibitor MPT0B098. MPT0B098 is......
