Composed of lipid A, a core oligosaccharide, and an O-specific polysaccharide, LPS exhibits strong immunogenicity. It activates immune cells via the TLR4 receptor, induces chemotactic cell migration and cytokine secretion, and helps maintain the integrity of the bacterial outer membrane, protecting against bile salts and lipid-based antibiotics. LPS is commonly used to establish inflammatory models, including arthritis, chronic obstructive pulmonary disease (COPD), acute respiratory distress syndrome (ARDS), and gastrointestinal disease models.

NM-3 is an orally available anti-angiogenic inhibitor with anti-tumour activity.NM-3 is used as a radiation modulator in vitro and in vivo.NM-3 inhibits vascular endothelial growth factor (VEGF), thereby inhibiting the proliferation of endothelial cells. This inhibits the proliferation of endothelial cells. NM-3 is associated with a mechanism of apoptosis induction by reactive oxygen species.

VEGFR-3-IN-1 is a novel, potent, and selective VEGFR3 inhibitor with an IC50 of 110.4 nM. It exhibits antitumor activity, inactivates the VEGFR3 signaling pathway, and inhibits the proliferation and migration of VEGF-C-induced human dermal lymphatic endothelial cells (HDLEC), MDA-MB-231, and MDA-MB-436 cells.

Vardenafil (Vivanza) is an oral therapy for the treatment of erectile dysfunction. It is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). Penile erection is a hemodynamic process initiated by the relaxation of smooth muscle in the corpus cavernosum and its associated arterioles. During sexual stimulation, nitric oxide is released from nerve endings and endothelial cells in the corpus cavernosum. Nitric oxide activates the enzyme guanylate cyclase resulting in increased synthesis of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the corpus cavernosum. The cGMP in turn triggers smooth muscle relaxation, allowing increased blood flow into the penis, resulting in erection. The tissue concentration of cGMP is regulated by both the rates of synthesis and degradation via phosphodiesterases (PDEs). The most abundant PDE in the human corpus cavernosum is the cGMPspecific phosphodiesterase type 5 (PDE5); therefore, the inhibition of PDE5 enhances erectile function by increasing the amount of cGMP.

L-Arginine hydrochloride serve as substrates and nitrogen donors for endothelial nitric oxide synthase (eNOS) to produce nitric oxide (NO). They are transported into vascular smooth muscle cells via cationic amino acid transporters, where they are metabolized into NO, polyamines, or L-proline. As effective vasodilators, they are commonly used to induce experimental acute pancreatitis models.

Azilsartan (TAK-536) is an Angiotensin 2 Receptor Blocker that acts as an Angiotensin 2 Type 1 Receptor Antagonist, leading to a physiologic effect of decreased blood pressure.

Cabozantinib (XL184) is a multi-targeted tyrosine kinase receptor inhibitor that inhibits VEGFR2, c-Met, Kit, Axl, and Flt3 (IC50=0.035/1.3/4.6/7/11.3 nM). Cabozantinib exhibits both antitumor and antiangiogenic activity.

L-Arginine (L-Arg) is a substrate for endothelial nitric oxide synthase (eNOS), participating in protein synthesis, polyamine production, and cellular signaling regulation. L-Arginine is transported into vascular smooth muscle cells via the cationic amino acid transporter family and metabolized into nitric oxide, polyamines, or L-proline. L-Arginine is an effective vasodilator and can be used to induce experimental acute pancreatitis.

Addition of the Rhamnose (6-Deoxy-L-mannose)-rich polysaccharide, RROP-1, to normal human dermal fibroblasts (NHDFs) and human endothelial cells produced a dose-dependent stimulation of the calcium-signaling pathway, inducing fast and transient increases in Ca2 influx and intracellular free Ca2 level.

Calcium dobesilate(CaD) has angioprotective properties and protects endothelial cells partly by ameliorating HG induced inflammation.

Otaplimastat HCl is a matrix metalloproteinase (MMP) inhibitor that blocks NMDA receptor-mediated excitotoxicity competitively and exhibits antioxidant activity,In oxygen-glucose-deprived endothelial cells, otaplimastat suppressed the activity rather than protein expression of MMPs by restoring the level of tissue inhibitor of metalloproteinase (TIMP) suppressed in ischemia, and consequently reduced vascular permeation. serving as a tool for research into brain ischemic injury and neuroprotection.

Safrole oxide was found to significantly inhibit neuronal cell growth and induce apoptosis. Safrole oxide elevated the levels of cyclooxygenase 2 (COX-2), interleukin-8 (IL-8) and reactive oxygen species (ROS), which was accompanied by nuclear factor-kappa B (NF-κB) nuclear translocation during the transdifferentiation, suggesting safrole oxide may induce endothelial cell transdifferentiation into functional neuron-like cells.

SU-4942 is a regulator of tyrosine kinase signaling. It inhibits VEGF and endothelial cell growth factor (ECGF)-induced mitosis in endothelial cells (US5792783A).

M8891 is an orally active, reversible, and brain-penetrant Methionine Aminopeptidase-2 (MetAP-2) inhibitor (IC50: 54 nM; Ki: 4.33 nM). It inhibits the growth of primary endothelial cells and tumor cells, demonstrating both antiangiogenic and antitumoral activity.

trans-Ned 19 is a nicotinic acid adenine dinucleotide phosphate (NAADP) antagonist and two-pore channel (TPC) blocker. It binds with high affinity to the NAADP receptor to inhibit NAADP-dependent lysosomal/endolysosomal calcium release without affecting IP3 or cADPR-mediated calcium signaling pathways. Functionally, trans-Ned 19 inhibits glucose-induced calcium oscillations in pancreatic islets and low histamine concentration-induced endothelium-dependent vasodilation, and reduces Ebola virus infection of host cells. In immunomodulation, NAADP signaling blockade by trans-Ned 19 promotes the conversion of mouse Th17 cells to regulatory T cells (Tregs) and shows protective effects in intestinal inflammation models.
