Dornidazole (PR-000350, PR-350, RP-343, PR-69) is an effective radiosensitizer for hypoxic cells with the potential for the treatment of non-small cell lung cancer (NSCLC) and pancreatic cancer.
Ingenol 3,20-dibenzoate is a powerful activator of protein kinase C (PKC) isoforms. It effectively induces the translocation of nPKC-delta, -epsilon, and -theta as well as PKC-mu from the cytosolic fraction to the particulate fraction. Through de novo synthesis of macromolecules, it triggers apoptosis with characteristic morphology. Moreover, Ingenol 3,20-dibenzoate enhances IFN-γ production and degranulation in NK cells, particularly when stimulated by NSCLCcells[1][2].
(E)-2-(2-Chlorostyryl)-3,5,6-trimethylpyrazine (CSTMP) is a stilbene derivative with antioxidant and anticancer activities. It stimulates proliferation of hydrogen peroxide-damaged ECV-304 cells (EC50 = 24.9 nM). CSTMP reduces hydrogen peroxide-induced release of lactate dehydrogenase (LDH) in and increases viability of human umbilical vein endothelial cells (HUVECs) in a concentration-dependent manner via inhibition of apoptosis. It reverses hydrogen peroxide-induced release of malondialdehyde (MDA) and decreases in superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities as well as increases constitutive nitric oxide synthase (cNOS) activity and nitric oxide (NO) production in HUVECs. CSTMP also induces cell death of A549 non-small cell lung cancer (NSCLC) cells in an IRE1α-dependent manner through induction of IRE1α-TRAF2-ASK1 complex-mediated endoplasmic reticulum (ER) stress and mitochondrial apoptosis.
CYH33 is an orally active, highly selective PI3Kα inhibitor with IC 50 s of 5.9 nM/598 nM/78.7 nM/225 nM against α/β/δ/γ isoform, respectively. CYH33 inhibits phosphorylation of Akt, ERK and induces significant G1 phase arrest in breast cancer cells and non-small cell lung cancer (NSCLC) cells. CYH33 has potent activity against solid tumors.
CYH33 methanesulfonate is a highly selective and orally active inhibitor of PI3Kα, with IC50 values of 5.9 nM, 598 nM, 78.7 nM, and 225 nM against the α, β, δ, and γ isoforms, respectively. This compound effectively inhibits the phosphorylation of Akt and ERK, leading to a significant G1 phase arrest in breast cancer cells and non-small cell lung cancer (NSCLC) cells. Additionally, CYH33 methanesulfonate demonstrates potent activity against solid tumors.
