FTM1 Flashcards
Digoxin
inhibits Na/K ATPase
Colchicine
anti-cancer by preventing polymerization or prevent of breakdown of MT
also an anti-inflammatory agent in gout patients
Taxol
stabilizes and prevents MT dissemble
Phalloidin
excessive polymerization of actin and prevents disassembly
Cytochalasin
blocks polymerization of actin
quinolones
Prevents ligation of cleaved DNA duplex by Gyrase
Etoposide
poison for Topo II in Euk
Camptothecin
Poison for TOPO I in Euk
Actinomyocin D
prevents formation of SS DNA so both transcription and translation are halted. common chemo therapy used in Wilm tumor, testicular cancer and Kaposi Sarcoma
Oubain
Na/K ATPase
Clonidine
lowers BP
Atenolol
Lowers HR
Didanosine
HIV drugs that inhibits RT. adds 3 phosphates, nucleoside analogue of adenosine
Tenofovir
HIV drug that inhibits RT, adds 2 phosphates and it is an analogue of a nucleotide (adenosine monophosphate)
Acyclovir
HIV drug that inhibits DNA pol of virus. it adds 3 phosphates and it is a nucleoside analogue of guanosine. it requires viral thymidine kinase so it is selective
Cytosine arabinoside (araC)
anti-cancer by inhibiting DNA pol. nucleoside analogue of cytosine. it adds 3 phosphates
important in leukemia and lymphoma patients
ara A (adenosine arabinoside)
anti-cancer by inhibiting DNA pol. it adds 3 phosphates.
important anti-neoplastic agent in patients with relapsed lymphoma and leukemia
AZT
HIV drug than inhibits RT. it adds 3 phosphates. it is used a combination drug, it is a nucleoside analogue of thymidine
Rifampin
blocks transcription by preventing the first phosphodiester bond to form. particularly affective on gram + bacteria and TB
Alpha-Amanatin
binds to RNA pol and prevents transcription. initial symptoms seen in intestine followed by liver and kidney failure. to treat from this poisoning do decontamination of gastrointestine, high doses of PENICILLIN or liver transplant
Toxin A
comes from Diptheria which causes infection in upper respiratory tract . it inhibits protein synthesis. give patients Nicotinamide as part of treatment
Streptomycin
inhibits initiation of translation, OTOTOXICITY. binds to 30S subunit of ribosome and prevents binding of f-MET to P site
Tetracycline
binds to 30S and 40S, inhibits elongation by prevent aminoacyl tRNA to bind to A site
Erythromycin
binds to 50S and prevent translocation of elongation. mostly used for gram + bacteria
Chloramphenicol
binds to 50S and inhibits elongation by inhibiting peptidyl transferase activity . haematological toxicity may occur so save only for serious infections
cycloheximide
research purpose only! binds to 60S and inhibits elongation by inhibitin peptidyl transferase activity. Will not affect mito proteins. CANNOT GIVE TO HUMANS
Puromycin
analogue of phenylalanine and inhibits elongation via premature termination of translation
it works for both humans and prok.
Mycophenolic Acid
inhibits IMP dehydrogenase in purine synthesis which deprives B and T cells of nucleotides they need and so reduces the immune system activity so it is often used as immunosupressant
hydroxylurea
anti cancer drug to inhibit synthesis of DNA by inhibiting ribonuclease reductase
probenecid
increases secretion of uric acid in urine
Allopurinol
decreases the formation of uric acid
febuxostat
decreases formation of uric acid
methylxanthine
inhibits Achesterase so cAMP presists
atenolol
a beta blocker used to reduce heart rate an regulate tachycardia
sulfanomide
inhibits dihydropteroate synthase in bacteria to prevent formation of Tetrahydrophlorate
