Metabolism/Protease Compound Library

7,056 compounds

Metabolism is the set of life-sustaining chemical reactions in organisms. Metabolic pathways are enzyme-mediated biochemical reactions that lead to biosynthesis (anabolism) or breakdown (catabolism) of natural product small molecules within a cell or tissue. Acting as catalysts, enzymes are crucial to metabolism - they allow a reaction to proceed more rapidly - and they also allow the regulation of the rate of a metabolic reaction. Proteases are used throughout an organism for various metabolic processes. Proteases control a great variety of physiological processes that are critical for life, including the immune response, cell cycle, cell death, wound healing, food digestion, and protein and organelle recycling. Imbalances in metabolic activities have been found to be critical in a number of pathologies, such as cardiovascular diseases, inflammation, cancer, and neurodegenerative diseases.

MCE designs a unique collection of 7,056 Metabolism/Protease-related small molecules that act as a useful tool for drug discovery of metabolism-related diseases.

Ac-Asp-Glu-Asp(EDANS)-Glu-Glu-Abu-ψ-(COO)Ala-Ser-Lys(DABCYL)-NH2 HCV NS3 Protease substrate	Peptides	Others
Ac-Asp-Glu-Asp(EDANS)-Glu-Glu-Abu-ψ-(COO)Ala-Ser-Lys(DABCYL)-NH2 (HCV NS3 protease substrate) is a biological active peptide. (This peptide is a HCV protease substrate incorporating an ester bond between residues P1 and P1. Due to ready transesterification of the scissile bond to the acyl-enzyme intermediate, this substrate shows very high kcat/Km values, enabling detection of activity with subnanomolar nonstructural protein 3 (NS3 protease) concentrations. It is widely used for the continuous assay of NS3 protease activity. Substrate cleavage is proportional to the enzyme concentration with a detection limit for NS3 between 1 nM and 250 pM.

Pheophytin a	Suaeda vermiculata Forssk. ex J.F.Gmel. Structural Classification Alkaloids Other Alkaloids Amaranthaceae Plants Source Classification	ERK Reactive Oxygen Species (ROS) COX PGE synthase STAT HCV HCV Protease
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 .
