Samelisant dihydrochloride (SUVN-G3031) is a antagonist of histamine H3 receptor with potential for the treatment of cognitive impairment, dementia, attention deficit hyperactivity disorder, epilepsy, sleep disorders, obesity, schizophrenia, eating disorders, and pain.
CAY10760 is an inhibitor of the protein-protein interaction between RAD51 recombinase and BRCA2 (EC50= 19 μM in a cell-free competitive ELISA).1It decreases homologous recombination by 54% in wild-typeBRCA2-expressing BxPC-3 pancreatic cancer cells when used at a concentration of 20 μM. CAY10760 (20 μM) decreases proliferation of BxPC-3, as well as mutantBRCA2-expressing Capan-1, cancer cells when used alone or in combination with the poly(ADP-ribose) polymerase (PARP) inhibitor olaparib . 1.Bagnolini, G., Milano, D., Manerba, M., et al.Synthetic lethality in pancreatic cancer: Discovery of a new RAD51-BRCA2 small molecule disruptor that inhibits homologous recombination and synergizes with olaparibJ.

C2 Adamantanyl globotriaosylceramide (AdaGb3) is a bioactive sphingolipid and water-soluble form of globotriaosylceramide that contains an adamantanyl group in place of the fatty acyl chain. It inhibits Vero toxin binding to globotriaosylceramide in an ELISA assay when used at a concentration of 10 μM. AdaGb3 decreases cell surface expression of P-glycoprotein (P-gp) and reduces efflux of rhodamine 123 in MDCK cells. It also increases apical-to-basal transport of vinblastine in human intestinal C2BBe1 cells.
R-8507 is a small molecule antagonist of the TNF-α type 1 receptor (TNF-αRI). It inhibits the expression of intercellular adhesion molecule-1 (ICAM-1) induced by TNF-α and IL-1β with EC50 values of 2.45 and 3.79 μM, respectively, in an ELISA using A549 lung epithelial cells.{|Gururaja2007|} It also disrupts the interaction of the TNF-αRI with receptor interacting protein 1 (RIP1) and TNF-αR-associated death domain protein (TRADD), preventing internalization of the receptor complex.
Blapsin B is a potent 14-3-3 inhibitor. Blapsin B is a naturally occurring compound isolated from the ethanol extract of the stink beetle, Blaps japanensis. Blapsin B potently inhibited 14-3-3 protein-protein interactions (PPIs) with IC(50) value of 10.0 μM as determined by an ELISA assay, and 2.5 μM in an FP assay, respectively. Blapsin B represent the first example of natural small-molecule 14-3-3 inhibitors.
