Pmcol 200 Drugs Exam Study Guide
Penicillin and cephalosporin - answer✔class: cell wall inhibitor
transpeptidase inhibitor
bacteriocidal
beta lactam ring
beta-lactamases - answer✔bacterial enzymes that hydrolyze the beta-lactam ring of penicillins
and cephalosporins
made by staphylococci and other gram negative bacteria
beta lactam inhibitors - answer✔calvanulic acid
inhibitor of beta-lactamases
vancomycin - answer✔cell wall inhibitor
inhibits peptidoglycan cross linking
NOT a beta-lactam
Sulfonamides - answer✔folic acid inhibitor
competes with PABA
trimethoprim - answer✔folic acid inhibitor
resembles dihydrofolic acid
chloramphenicol and macrolides - answer✔protein synthesis inhibitors
bind 50S subunit and block transpeptidation
tetracylines - answer✔protein synthesis inhibitor
bind 30s subunit
aminoglycosides - answer✔protein synthesis inhibitor
bind 30s subunit

1. block initiation of the complex
2. cause misreading of code on mRNA template
3. inhibit translocation
Acyclovir - answer✔antiviral
nucleoside analog - DNA chain termination
Amantadine - answer✔antiviral
inhibits viral uncoating of influenza A - blocks proton transfer through M2, blocking
acidification and initiation of viral transcription
Zanamivir - answer✔Antiviral. Inhibits NA in Influenza => viral aggregation; unable to exit
host cell; and reduced spread in airways.
Maraviroc - answer✔CCR5 receptor antagonist (entry inhibitor)
NTRIs - answer✔nucleoside reverse transcriptase inhibitor
compete with nucleoside triphosphates
non-NTRIs - answer✔bind different site than NTRIs and inhibit activity of reverse transcriptase
Raltegravir - answer✔Integrase Strand Transfer Inhibitor (INST)
Protease inhibitors - answer✔inhibits aspartate proteases (HIV-1 protease)
inhibits formation of mature virion
pyrimidine analogues - answer✔5-fluorouracil (5-FU)
compete for enzyme thymidylate synthase
purine analogues - answer✔6-mercaptopurine
inhibits purine nucleotides synthesis by inhibiting PRPP amidotransferase
cyclophosphamide - answer✔alkylating agent
most susceptible in late G1/S
covalently links chemical groups in NA, cross-links DNA and breaks strands
cisplatin - answer✔alkylating agent
platinum analog
leads to inter-strand crosslinks, leading to inhibition of DNA synthesis and function
