FPFS-1169 (BPAP-CPD, R-(-)-BPAP, R- FpFS-1169) is a proto-oncogene protein C-Bcl-2 stimulant that is one of the catecholaminergic and serotonergic enhancers and may be used for the treatment of Parkinson's disease.
Afatinib impurity 11 is an impurity of Afatinib. Afatinib is an irreversible EGFR family inhibitor with IC50s of 0.5 nM, 0.4 nM, 10 nM and 14 nM for EGFRwt, EGFRL858R, EGFRL858R T790M and HER2, respectively[1]. [1]. Li D, et al.

Tpl2 kinase inhibitor is an inhibitor of tumor progression locus 2 (Tpl2; IC50= 0.05 μM).1It is selective for Tpl2 over MEK, p38 MAPK, Src, MK2, and PKC (IC50s = >40, 180, >400, 110, and >400 μM, respectively). Tpl2 kinase inhibitor inhibits LPS-induced TNF-α production in isolated human monocytes and whole blood (IC50s = 0.7 and 8.5 μM, respectively). It enhances differentiation induced by calcitriol in HL-60 and U937 leukemia cells when used at a concentration of 5 μM.2Tpl2 kinase inhibitor (5 μM) inhibits the proliferation of KG-1a leukemia cells.3 1.Garvin, L.K., Green, N., Hu, Y., et al.Inhibition of Tpl2 kinase and TNF-α production with 1,7-naphthyridine-3-carbonitriles: Synthesis and structure-activity relationshipsBioor.

Cyclopamine-KAAD is a potent inhibitor of hedgehog signaling with an IC50 value of 20 nM in a Shh-LIGHT2 assay. It blocks binding of BODIPY-cyclopamine to cells expressing Smoothened (Smo) in a dose-dependent manner. Cyclopamine-KAAD is cell-permeable and binds to SmoA1 to promote its exit from the endoplasmic reticulum. It inhibits the invasion and migration (45.9 and 43.3% inhibition, respectively) of Bel-7402 hepatocarcinoma cells and decreases the expression of nuclear glioma-associated oncogene 1 (Gli1) and cytosolic MMP-9, pERK1, and pERK2 proteins in a dose-dependent manner. Cyclopamine-KAAD also increases TRAIL-mediated cell death in NCH82 and NCH89 human glioblastoma cultures and upregulates expression of the death receptors DR4 and DR5 in LN229 and U251 glioma cells.
CAY10722 is an inhibitor of sirtuin 3 (SIRT3), a class III HDAC (71% inhibition at 200 μM). SIRT3 is involved in modulating metabolic homeostasis as a NAD+-dependent protein deacetylase in the mitochondria. SIRT3 functions as either an oncogene or tumor suppressor, depending on cancer cell type. High SIRT3 expression in patient-derived esophageal cancer tissues is associated with shorter survival and, in mice, downregulation leads to a lower tumor load. In contrast, low SIRT3 expression in patient-derived breast cancer cells is correlated with shorter survival.
