Streptomycin MOA | Binds to 30S ribosome & changes its structure -aminoglycoside |
Tetracycline MOA | Binds to 30S subunit & blocks tRNA from coming into the "A" site (EPA) -can cuase tooth stain due to a mis-sense mutation |
Rifampin | Fights tuberculosis by interfering with tranSCRIPTION |
Aminoglycosides MOA | -Streptomycin binds to 30S ribosome and inhibit translation |
Streptomyin, tetraycin, and clindamycin MOA | Inhibit ribosomes AND translation (protein synthesis) |
Antibiotics that bind to the 50S subunit? | Clindamycin & erythroycin -erythromycin and penicillin are antagonistic to each other and will CANCEL each other out so don't give togehter |

Methotrexate MOA | -Used to treat cancer -incorporated into DNA S phase of the cell cycle -Inhibits production of tetrahydrofolic acid (TFA) -TFA is used by some enzymes in purine and pyrimidine synthesis so methotrexate stops production of purines and pyrimidines |
Sulfonamide MOA | Look like PABA & compete to inhibit in the synthesis of folic aid -therefore, cannot make purines & pyramidines |
Streptomycin does what | Binds to ribosome and changes its structure |
Clindamycin/erythromycin | Binds to ribosome 50s subunit and prevents it from moving along mRNA |

*if have denture give the rinse... make sure they use orally and to clean denture | * troches work better bc they stay in mouth longer than rinse... they have more contact w/ infection for longer period of time |

-bicin | antineoplastic |
-bital | barbiturate *phenobarbital*, butabarbital, secobarbital Used as anticonvulsants (also have anxiolytic and hypnotic effects, but benzodiazepines replaced barbiturates for this use) |
