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.

    ICSN3250
    		Activator
    ICSN3250 is a halitulin analogue and specific mTORC1 inhibitor. ICSN3250 directly binds to mTOR's FRB domain and displaces phosphatidic acid (PA), reversing mTORC1 activation. ICSN3250 shows high cytotoxicity in cancer cells (nanomolar concentration) through a caspase-independent cell death mechanism. ICSN3250 specifically inhibits the mTORC1 pathway, inducing autophagy and G0-G1 cell-cycle arrest in cancer cells. ICSN3250 can be used for the study of cancer.

    Apoptosis inducer 50
    		Activator
    Apoptosis inducer 50 (Compound 5e) is an apoptosis inducer as well as an autophagy inducer agent. Apoptosis inducer 50 exhibits potent and selective anti-cancer activity against triple-negative breast cancer cells and metastatic colon cancer cells. Apoptosis inducer 50 upregulates the expression of pro-apoptotic proteins (Bax, Bim, cleaved Caspase-9) and downregulates the expression of the anti-apoptotic protein (BCL-XL). Apoptosis inducer 50 upregulates key autophagy markers such as Beclin-1 and ATG5, and enhances the conversion of LC3-I to LC3-II., Apoptosis inducer 50 arrests cancer cells in the G1/S phase by upregulating the expression of p21 and p27 while downregulating Cyclin D1. Apoptosis inducer 50 increases the level of ROS.

    LC3B recruiter 2
    		98.11%
    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.
