Apoptosis

Apoptosis is a distinctive form of cell death exhibiting specific morphological and biochemical characteristics, including cell membrane blebbing, chromatin condensation, genomic DNA fragmentation, and exposure of specific phagocytosis signaling molecules on the cell surface. Cells undergoing apoptosis differ from those dying through necrosis. Necrotic cells are usually recognized by the immune system as a danger signal and, thus, resulting in inflammation; in contrast, apoptotic death is quiet and orderly.

There are two major pathways of apoptotic cell death induction: The intrinsic pathway, also called the Bcl-2-regulated or mitochondrial pathway, is activated by various developmental cues or cytotoxic insults, such as viral infection, DNA damage and growth-factor deprivation, and is strictly controlled by the BCL-2 family of proteins. The extrinsic or death-receptor pathway is triggered by ligation of death receptors (members of the tumor necrosis factor (TNF) receptor family, such as Fas or TNF receptor-1 (TNFR1)) that contain an intracellular death domain, which can recruit and activate caspase-8 through the adaptor protein Fas-associated death domain (FADD; also known as MORT1) at the cell surface. This recruitment causes subsequent activation of downstream (effector) caspases, such as caspase-3, -6 or -7, without any involvement of the BCL-2 family.

Studies suggest that alterations in cell survival contribute to the pathogenesis of a number of human diseases, including cancer, viral infections, autoimmune diseases, neurodegenerative disorders, and AIDS (acquired immunodeficiency syndrome). Treatments designed to specifically alter the apoptotic threshold may have the potential to change the natural progression of some of these diseases.

    Pectolinarigenin
    Inducer 99.98%
    Pectolinarigenin is an orally active dual inhibitor of COX-2/5-LOX with anti-inflammatory, antioxidant, antitumor and neuroprotective activities. Pectolinarigenin exerts neuroprotective and anti-inflammatory effects on astrocyte inflammation via the NFκB and MAPK pathways. Pectolinarigenin inhibits LPS-induced phosphorylation of ERK1/2, N-FκB and p38MAPK, directly inhibits the enzymatic activity or binding of COX-2, 5-LOX and HIF-1α, and reduces the level of XIAP. Pectolinarigenin modifies Keap1 to promote nuclear accumulation of Nrf2, induces ARE-mediated antioxidant enzyme expression, and possesses direct free radical scavenging activity. Pectolinarigenin reduces the release of NO, proinflammatory mediators and leukotrienes, and increases the level of IL-10. Pectolinarigenin induces G2/M cell cycle arrest, apoptosis (Apoptosis) and autophagy (Autophagy) via the PI3K/AKT/mTOR signaling pathway. Pectolinarigenin reduces renal crystal deposition and inhibits melanin synthesis. Pectolinarigenin inhibits inflammation and alleviates allergy in mouse models of inflammation. Pectolinarigenin alleviates renal injury, inflammation and oxidative stress in mice by inhibiting HIF-1α activity. Pectolinarigenin can be used for the research of neurodegenerative diseases, inflammatory/allergic diseases, calcium oxalate nephrocalcinosis, gastric cancer, melasma, post-inflammatory diseases and chloasma.

Isorhapontigenin induces autophagy, apoptosis and preadipocyte differentiation; it inhibits tumor growth, cell invasion, NF-κB transcriptional activity, the PI3K/Akt signaling pathway, STAT1 phosphorylation and MMP-2 expression. Isorhapontigenin alleviates oxidative stress, inflammatory cytokine release and triglyceride accumulation; it increases intracellular ATP levels and promotes Nrf2 nuclear translocation. Isorhapontigenin improves insulin sensitivity in adipose tissue and glucose tolerance, and reduces postprandial blood glucose, insulin and free fatty acid levels.
