Atg8/LC3

Autophagy-related 8;

Autophagy-related 8 proteins (Atg8s) are one of the 62 highly conserved eukaryote-specific protein families. Whereas yeast and other fungal species have a single Atg8 gene, multicellular animals, green plants and some protists have several. Animal Atg8 proteins comprise three subfamilies: microtubule-associated protein 1 light chain 3 (MAP1LC3, hereafter referred to as LC3), γ-aminobutyric acid receptor-associated protein (GABARAP) and Golgi-associated ATPase enhancer of 16 kDa (GATE-16).

Atg8 family members are expressed in various tissues, where they participate in multiple cellular processes, such as intracellular membrane trafficking and autophagy. Their role in autophagy has been intensively studied. Atg8 proteins undergo a unique ubiquitin-like conjugation to phosphatidylethanolamine on the autophagic membrane, a process essential for autophagosome formation.

    Microcolin H
    Microcolin H is a marine lipopeptide and phosphatidylinositol transfer protein ligand that targets PITPα/β. Microcolin H increases the conversion of LC3I to LC3II and reduces p62 levels in cancer cells, leading to autophagy cell death (Autophagy). Microcolin H effectively inhibits tumor development and has anti-proliferative activity in nude mouse subcutaneous tumor models.

    OSU-53
    OSU-53 is an orally active AMPK activator (EC50: 0.3 μM) and a direct mTOR inhibitor. OSU-53 induces autophagy and increases conversion of LC3 I to LC3 II. OSU-53 also modulates energy homeostasis by suppressing fatty acid biosynthesis and shifting the metabolism to oxidation by up-regulating the expression of PGC1α and NRF-1. OSU-53 has antitumor activity in various tumor models, such as breast cancer and thyroid cancer.

    Citronellol (Standard)
    		Inhibitor
    Citronellol (Standard) is the analytical standard of Citronellol. Citronellol (Standard) is an orally active inducer of apoptosis. Citronellol (Standard) can prevent oxidative stress, mitochondrial dysfunction, and apoptosis in the SH-SY5Y cell Parkinson's disease model induced by 6-OHDA by regulating the ROS-NO, MAPK/ERK, and PI3K/Akt signaling pathways. Citronellol (Standard) can induce necroptosis in human lung cancer cells through the TNF-α pathway and accumulation of ROS. Citronellol (Standard) can reduce the levels of LC-3 and p62 to regulate the autophagy pathway, inhibit oxidative stress and neuroinflammation, and thus have neuroprotective effects on Parkinson's rats. Citronellol (Standard) exhibits anti-fungal activity against Trichophyton rubrum by inhibiting ergosterol synthesis.

    Astin B
    Astin B is a orally active and potent cyclic pentapeptide, that can be isolated from Aster tataricus. Astin B has hepatotoxic effects in vitro and in vivo and that hepatic injury was primarily mediated by apoptosis in a mitochondria/caspase-dependent manner. Astin B induces autophagy in L-02 cells, increases LC3-II and decreases p62 expression.

    LC3B recruiter 2
    LC3B recruiter 2 (34R) is an LC3B recruiter and a component of the autophagy-lysosome pathway degradation system (ATTEC, Autophagy-Tethering Compounds), which directly binds to LC3B. LC3B recruiter 2 binds to CDK9 inhibitor SNS-032 (HY-10008) through a linker, forming an ATTEC that targets the degradation of the CDK9 and Cyclin T1 complex (with inhibitory effects on both). Therefore, LC3B recruiter 2 exerts activity through the LC3B-dependent autophagy-lysosome pathway, interfering with the cell cycle of cancer cells, thus exhibiting antitumor activity.
