Pheophytin a is a multi-target inhibitor, anticancer agent, antioxidant and antiviral agent. Pheophytin a directly binds to and inhibits HCV-NS3/4A protease (IC50=0.89 μM) to block viral replication. Pheophytin a also scavenges free radicals, reduces ferric ions, and exhibits cytotoxic activity against breast cancer cells. Pheophytin a effectively inhibits LPS-induced production of nitric oxide, prostaglandin E2, NOS2 and COX-2, as well as various pro-inflammatory cytokines, by downregulating the transcription levels of inflammatory mediators and blocking the ERK1/2 and STAT-1 pathways. In a low nerve growth factor environment, Pheophytin a also enhances ERK1/2 phosphorylation and synergistically promotes neurite outgrowth through MAPK pathway. Pheophytin a can be used to investigate the pathogenic mechanisms of diseases including chronic hepatitis C, sepsis, breast cancer and Alzheimer's disease .

Target:  

Endogenous Metabolite

Research Areas:  

Neurological Disease

Propanedial (Malondialdehyde) (13.88 mM in water) is one of the final products of lipid peroxidation. Propanedial causes protein inactivation, DNA damage and cross-linking by forming stable covalent adducts with biological macromolecules, which is the main mechanism for its cytotoxicity and genotoxicity. Propanedial production increases with the elevation of free radicals. Propanedial is a key biomarker for evaluating the level of cellular oxidative stress [1][2][3].

23S rRNA (adenine2503-C2)-methyltransferase (EC 2.1.1.192) contains a [4Fe-4S] cluster and belongs to the "radical AdoMet" (radical SAM) family. It employs a radical-based mechanism to methylate the adenosine residue using a CH? group derived from S-adenosyl-L-methionine, while retaining the hydrogen atom at the C-2 position of adenosine 2503 in the 23S rRNA.

LHA585 is a fluorescent probe targeting the lipid hydrogen abstraction process for the early detection of ferroptosis (Ferroptosis). Its detection mechanism relies on the reactivity of its own 4-phenyl-3-methylbut-2-enyl moiety with biologically relevant oxidative radicals, including peroxyl radicals (ROO·), alkoxyl radicals (RO·), hydroxyl radicals (HO·), and peroxynitrite anions (ONOO−); upon hydrogen abstraction from this structure, radical rearrangement and radical cleavage occur, releasing a xanthene radical which converts into a highly fluorescent rhodamine dye in biological environments, thereby achieving a fluorescence turn-on ratio of up to 360-fold. LHA585 is non-fluorescent in its native state, possesses excellent membrane permeability due to its non-polar property, and the rhodamine dye generated after oxidation diffuses into mitochondria. The excitation wavelength of LHA585 is 561 nm, and its emission wavelength ranges from 570 to 620 nm .
