Ligands organométalliques

Inhibitor of poly (ADP-ribose) polymerase enzyme; antineoplastic

Idelalisib is a pharmaceutical drug that functions as a PI3Kδ inhibitor, developed through synthetic chemical processes. Its mode of action involves selectively targeting and inhibiting phosphatidylinositol 3-kinase delta (PI3Kδ), a lipid kinase that plays a crucial role in the signaling pathways responsible for cell proliferation, survival, and differentiation. By inhibiting this enzyme, Idelalisib effectively impedes pathways that are often hyperactivated in certain hematologic malignancies, thereby exerting antitumor effects.

Afatinib is a small molecule that inhibits the activity of cellular kinases that are involved in the progression of cancer. It is an Irreversible inhibitor of three members of the ErbB family. This molecule binds covalently to cysteine 797 residue in HER2 and blocks downstream cellular signalling which inhibits cellular growth and promotes apoptosis. It has been researched for the treatment of non-small cell lung cancer (NSCLC), breast cancer, pancreatic cancer and colorectal cancer.

Carmustine is a DNA alkylating agent which also cross-links DNA. As a result, Carmustine disrupts the function of DNA, resulting in the arrest the cell cycle and apoptosis. Consequently these properties of Carmustine, in addition to its ability to easily transmit through the blood-brain barrier, means it can be used as a cancer treatment, treating cancers such as, breast, ovarian and pancreatic as well as lymphomas and leukemias. Furthermore Carmustine can contribute to cytotoxic effects through its ability to carbamoylate DNA repair enzymes and proteins.

FTBMT is a GPR52 receptor agonist with an EC50 value of 71 nM. Studies demonstrate antipsychotic-like effects of FTBMT in murine models of schizophrenia. FTBMT elicits beneficial effects on cognitive processes such as spatial working memory and long-term memory in mice.

Inhibitor of 8-oxoguanine DNA glycosylase OGG1 with IC50 of 0.059 μM and excellent specificity over other DNA repair enzymes. OGG1 and its substrate 8-oxoguanine are involved in mutagenesis, genotoxicity, inflammation and cancer. The compound can cause accumulation of 8-oxoguanine in DNA in vitro and is a potent tool for the study of OGG1 biology.

Inhibits actin polymerization

Inhibitor of BACE1 protease

Cetilistat is a drug that is used to treat obesity. This drug inhibits the enzyme pancreatic lipase and so it prevents triglycerides from being hydrolyzed into absorbable free fatty acids.

Inhibits multiple tyrosine kinases (Abl1, Src family kinases, Tie-2 and VEGFR-2)

Inhibitor of TGF-α, CTGF, ERK1/2, NF-κB and FasL; anti-inflammatory

AZD-7648 is a selective inhibitor of DNA-dependent protein kinase (DNA-PK), which is a pivotal enzyme involved in the non-homologous end joining (NHEJ) pathway of DNA repair. This product is derived from extensive chemical synthesis and optimization, designed for its specificity and efficacy in inhibiting DNA-PK activity. The mode of action involves binding to the ATP-binding site of DNA-PK, thereby obstructing its ability to facilitate the repair of double-strand DNA breaks.

Dual inhibitor of the adaptor protein 2-associated kinase 1 (AAK1) and BMP2-inducible kinase (BMP2K) with IC50 values of 270 nM and 1 μM, respectively. In a recent study, SGC AAK1 1 stabilised β-catenin, inhibited phosphorylation of the AP2 complex subunit mu protein (AP2M1) and activated Wnt signalling in in vitro experiments._x000D_

Specific inhibitor of glycogen synthase kinase 3 (GSK-3) with IC50 in low nanomolar range. Studies showed that BIO maintains self-renewal in embryonic stem cells (ESCs) as well as increases activity of β-catenin. In neonatal cardiomyocytes, BIO promotes cell cycle by stimulating cell entry into S phase as well as cytokinesis. In germline stem cells from female mice (FGSCs), BIO promoted proliferation and maintenance of FGSCs by activating β-catenin and up-regulating E-cadherin.

Inhibitor of glutathione peroxidase GPX4

Brimonidine-D-tartrate is a selective alpha-2 adrenergic agonist, which is a pharmacological compound derived synthetically, targeting specific receptor subtypes in the adrenergic receptor family. Its mode of action involves reducing aqueous humor production and increasing uveoscleral outflow in the eye, thereby lowering intraocular pressure. Additionally, it induces peripheral vasoconstriction, playing a role in reducing redness in rosacea.

Dapoxetine is a drug that belongs to the group of selective serotonin reuptake inhibitors (SSRIs). It is used to treat premature ejaculation. This drug inhibits the serotonin transporter allowing for an increased action of serotonin at the postsynaptic cleft, thus promoting ejaculatory delay.

Ebselen is a non-toxic organoselenium compound with antioxidant, anti-inflammatory and cytoprotective properties. Ebselen is an inhibitor of lipoxygenases, nitric oxide (NO) synthases, protein kinase C, H+/K+-ATPase, thioredoxin reductase and NADPH oxidase. Recently, ebselen has been identified by several studies as a covalent inhibitor of the main protease Mpro from coronaviruses. For the SARS-CoV-2 main protease Mpro, the IC50 value is 0.67 μM and EC50 is 4.57 μM.

Sarpogrelate is a serotonin antagonist drug that is used for the treatment of various diseases such as diabetes, coronary artery disease and atherosclerosis. This drug inhibits serotonin-induced platelet aggregation.
