Silver sulfadiazine Drug Metabolism

Homo sapiens
Silver sulfadiazine is a drug that is not metabolized by the human body as determined by current research and biotransformer analysis. Silver sulfadiazine passes through the liver and is then excreted from the body mainly through the kidney.

Simeprevir Action Pathway

Homo sapiens
Simeprevir is a direct-acting antiviral agent that inhibits HCV NS3/4A protease to treat chronic hepatitis C virus (HCV) infection in adults with HCV genotype 1 or 4. Hepatitis C virus lipoviroparticles enter target hepatocytes via receptor-mediated endocytosis. The lipoviroparticles attach to LDL-R and SR-B1, and then the virus binds to CD81 and subsequently claudin-1 and occludin, which mediate the late steps of viral entry. The virus is internalized by clathrin-dependent endocytosis. RNA is released from the mature Hepatitis C virion and translated at the rough endoplasmic reticulum into a single Genome polyprotein. Simeprevir accumulates in the liver after uptake into hepatocytes via solute carrier organic anion transporter family member 1B1. Simeprevir inhibits NS3/4A protease, which is an enzyme that cleaves the heptatitis C virus polyprotein downstream of the NS3 proteolytic site, which generates nonstructural proteins NS3, NS4A, NS4B, NS5A, and NS5B. These proteins are required in viral RNA replication, therefore because of the inhibition of their formation, RNA replication cannot occur. Because RNA replication does not occur, the mature virion is unable to form. At higher concentration above their antiviral half-maximal effective concentration (EC50), simeprevir and other NS3/4A inhibitors also restore interferon (IFN)-signaling pathways that are thought to be disrupted by NS3/4A protease and recover innate immune processes. NS3/4A protease cleaves two essential adaptor proteins that initiate signaling leading to activation of IFN regulatory factor 3 and IFN-α/β synthesis, which are mitochondrial antiviral-signaling proteins.

Simvastatin Action Action Pathway Xuan

Homo sapiens
Simvastatin, the methylated form of lovastatin, is an inactive lactone that is metabolized in vivo to β,δ-dihydroxy acid, its most potent metabolite. Cytochrome P450 (CYP) enzymes, CYP3A4, CYP3A5, and CYP2C8, have been implicated in this activation step; CYP3A4/5 are responsible for ≥ 80% of simvastatin metabolism while CYP2C8 (not shown in pathway) contributes to ≤ 20% of its metabolism. The simvastatin hydroxy acid inhibits cholesterol synthesis via the mevalonate pathway by competitively inhibiting 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. HMG-CoA reductase, a hepatic microsomal enzyme, is the enzyme responsible for the conversion of HMG-CoA to mevalonic acid, the rate-limiting step of cholesterol biosynthesis by this pathway. The active hydroxy acid is structurally similar to the reduced reaction intermediate and competes with HMG-CoA for binding to HMG-CoA reductase. Cholesterol biosynthesis accounts for approximately 80% of cholesterol in the body; thus, inhibiting this process can significantly lower cholesterol levels.
