What drugs treat Herpes infections?
|
Acyclovir, Valacyclovir, Famciclovir, Gangciclovir, Cidofovir and Foscarnet
|
|
Acyclovir, Valacyclovir, and Famciclovir
|
Guanine analogues with no intact sugar residue
Require viral thymidine kinase to add first phosphate Result in chain termination |
|
Cidofovir
|
Cytosine Analogue with no intact sugar residue
Does not require viral thymidine kinase so good for acyclovir resistant strains Nephrotoxic |
|
Foscarnet
|
Complexes with DNA Pol to prevent removal of Pyrophosphates so that sugars can't connect
Nephrotoxic |
|
Ribavirin
|
Normal sugar but guanine base is altered
Incorporating nonsensical base leads no nonsense mrna |
|
Amantidine and Rimantidine
|
Bind to M2 Protein that facilitates uncoating of Influenza A
|
|
Olsetamavir and Zanamivir
|
Nueraminidase Inhibitors that prevent virus spreading to other cells
|
|
NRTIs
|
Antiretroviral
Has sugar with no OH so they can't be added on to- chain terminates |
|
NNRTIs: Efavirenz
|
Large molecule doesn't resemble nucleotide but binds RT and sterically hinders DNA production
|
|
Protease Inhibitors
Lopinavir, Atazanavir, Ritonavir |
Inhibits progression to mature virus
|
|
Enfuvirtide
|
Fusion inhibition
Corresponds to hydrophobic region of gp41 and blocks the conformational change that must occur for fusion |
|
Raltegravir
|
Integrase inhibitor that prevents HIV1 from incorporating into host genome
No viral protein is made |
|
Miraviroc
|
CCR5 Inhibitor
Hepatotoxic |
