Organometallic Ligands

<p>Inhibitor of chymotrypsin</p>

<p>Histamine (H2) receptor antagonist</p>

<p>A selective and potent inhibitor of phosphodiesterase 2 (PDE2). Raises cAMP and cGMP levels in neurons, improves social recognition and object memory in murine animals. Reverses anxiolytic effects induced by oxidative stress in mice by blocking cGMP-PKG signaling.</p>

<p>Inhibitor of immunophilin FKBP12 and mTOR signalling with immunosuppressant activity. Zotarolimus inhibits proliferation of endothelial cells and smooth muscle cells and is employed in vascular interventional therapies.</p>

<p>Venlafaxine is an antidepressant drug used in the treatment of major depression, anxiety disorder and panic disorder. It is classed as an SNRI drug meaning it inhibits the reuptake of serotonin and norepinephrine so that there is an increased level of the neurotransmitters in the synaptic cleft.</p>

<p>A cytidine analogue and inhibitor of DNA methyl transferases (DNMTs) with anti-cancer activity. This stable, hydrophilic compound forms covalent complexes between DNMT and zebularine-substrate DNA. It causes DNA lesions that block replication and cause replication fork collapse, leading to the formation of DNA double-strand breaks. It was also shown that zebularine-induced DNA methylation decrease in the IL-1β promoter region and disrupts molecular mechanisms of neuroinflammation. Moreover, this molecule down-regulates the DNA-methylation profile in the pluripotency genes’ promoters, which leads to improved development of somatic cell nuclear transfer (SCNT) embryos.</p>

<p>Estrogen receptor degrader; therapeutic use in breast cancer</p>

<p>A potent inhibitor of STING protein (stimulator of interferon genes), a protein that partakes in intracellular DNA sensing pathway.  H 151 blocks palmitoylation of STING, which is required for the formation of multimeric complexes for recruiting downstream signalling molecules. Inhibition of STING by H 151 reduces pro-inflammatory cytokine synthesis.</p>

<p>Rebamipide is a gastroprotective agent that is used to treat various gastrointestinal disorders such as gastric ulcers and GERD. This drug’s mechanism of action is not fully understood however, it is thought to exert its effects by promoting the secretion of protective mucus in the stomach and intestine, which helps to create a barrier against stomach acid and other irritants. Additionally, it has antioxidant and anti-inflammatory properties that can help reduce tissue damage.</p>

<p>Inhibits isocitrate dehydrogenase 1 (IDH-1) harbouring a gain of function mutation at R132, which causes impaired cellular differentiation via epigenetic modulation. By inhibiting mutant IDH1, synthesis of oncometabolite 2-hydroxyglutarate is reduced. This compound therefore has therapeutic potential in solid and haematological malignancies, such as acute myeloid leukemia (AML).</p>

<p>Sphingosine-1-phosphate receptor modulator</p>

<p>Activater of the Nrf2 pathway and an inhibitor of the NF-κB pathway.  Possible applications have extended to anti-viral treatment of COVID-19.</p>

<p>KBU2046 is an antimicrobial peptide, which is derived from natural or synthetic peptide sequences with potential therapeutic properties. It exerts its effects by disrupting the structure and integrity of bacterial cell membranes through the formation of pores or micelles. This action alters membrane permeability, ultimately leading to cell lysis and death.</p>

<p>A prodrug of VRT 043198 that inhibits IL-converting enzyme (ICE)/caspase-1.  Inhibits LPS-induced secretion of cytokines. It has therapeutic potential in autoinflammatory diseases. VX 765 is cardioprotective in addition to the P2Y12 receptor inhibitor congrelor, resulting in reduced myocardial infarction.</p>

<p>Inhibitor of FLT3 and AXL tyrosine kinases</p>

<p>17:0-20:4 Pi (4,5) P2 is a synthetic phosphoinositide, which is a chemically defined lipid derived from laboratory synthesis. It features a specific acyl chain composition with a heptadecanoic acid (17:0) at the sn-1 position and an arachidonic acid (20:4) at the sn-2 position. This phosphoinositide mimics naturally occurring phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2), an essential component of cellular membranes.</p>

<p>Inhibits MET, VEGFR1-3, Tie and Ron tyrosine kinases; antineoplastic</p>

<p>VEGFR tyrosine kinase inhibitor</p>

<p>Dopamine D2 receptor antagonist</p>

<p>Inhibits aromatic amino acid decarboxylase</p>
