Teicoplanin Action Pathway

Staphylococcus aureus
Teicoplanin is a glycopeptide antibiotic with a similar mechanism of action and spectrum of activity to vancomycin used to treat various infections caused by gram-positive bacteria. It is used for the treatment of bacterial infections caused by susceptible microorganisms. It is a glycopeptide antiobiotic extracted from Actinoplanes teichomyceticus, with a similar spectrum of activity to vancomycin. Its mechanism of action is to inhibit bacterial cell wall synthesis. Teicoplanin inhibits peptidoglycan polymerization, resulting in inhibition of bacterial cell wall synthesis and cell death. Oral teicoplanin has been demonstrated to be effective in the treatment of pseudomembranous colitis and Clostridium difficile-associated diarrhoea, with comparable efficacy to vancomycin. Teicoplanin is poorly absorbed after oral administration but is 90% bioavailable when administered intramuscularly.

Telaprevir Action Pathway

Homo sapiens
Telaprevir is an NS3/4A viral protease inhibitor used in combination with other antivirals for the curative treatment of chronic Hepatitis C Virus infections. 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. Paritaprevir accumulates in the liver after uptake into hepatocytes via solute carrier organic anion transporter family member 1B1. Paritaprevir 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), Paritaprevir 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.

Telavancin Action Pathway

Staphylococcus aureus
Telavancin is an antibacterial agent used in the treatment of complicated skin and skin structure infections and types of hospital-acquired bacterial pneumonia. Telavancin is a semi-synthetic derivative of vanocymycin that has bactericidal activity against Methicillin-resistant Staphylococcus aureus (MRSA) and other gram-positive bacteria. It is used for the treatment of complicated skin and skin structure infections (cSSSI) caused by gram-positive bacteria like methicillin-susceptible or -resistant Staphylococcus aureus, vancomycin-susceptible Enterococcus faecalis, and Streptococcus pyogenes, Streptococcus agalactiae, or Streptococcus anginosus group. It is also used for the treatment of adult patients with hospital-acquired bacterial pneumonia (HAP) and ventilator-associated bacterial pneumonia (VAP), known or suspected to be caused by susceptible isolates of Staphylococcus aureus (including methicillin-susceptible and methicillin-resistant S. aureus). Telavancin prevents polymerization of N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) and cross-linking of peptidoglycan by binding to D-Ala-D-Ala. As a result, inhibition of bacterial cell wall synthesis occurs. Furthermore, telavancin disrupts membrane potential and cell permeability as a result of the lipophillic side chain moiety. This additional bactericidal mechanism is what sets telavancin apart from vancomycin.

Telbivudine Action Pathway

Homo sapiens
Telbivudine is a synthetic thymidine nucleoside analog with specific activity against the hepatitis B virus. It is administered orally. Telbivudine is the unmodified β–L enantiomer of the naturally occurring nucleoside, thymidine. It undergoes phosphorylation via interaction with cellular kinases to form the active metabolite, telbivudine 5'-triphosphate. Telbivudine 5'–triphosphate inhibits HBV DNA polymerase (reverse transcriptase) by competing with the natural substrate, thymidine 5'–triphosphate. This leads to the chain termination of DNA synthesis, thereby inhibiting viral replication. Incorporation of telbivudine 5'–triphosphate into viral DNA also causes DNA chain termination, resulting in inhibition of HBV replication. Telbivudine inhibits anticompliment or second-strand DNA. This causes DNA chain termination, preventing the growth of viral DNA. Less Viral DNA is transported into the nucleus, therefore, less viral DNA is integrated into the host DNA. Less viral proteins produced, fewer viruses can form.

Telbivudine Drug Metabolism

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