Inosine
drug that preserves the quality of blood being kept in storage (blood loses its O2 carrying capacity from being stored in a blood bank -> (nucleoside containing adenine and ribose); increases blood quality
Nitric oxide
When blood loses its O2 carrying capacity from being stored in a blood bank -> increases blood quality
insulin
*during hyperglycemia it is a hormone that causes cells in the liver, muscle, and fat tissue to take up glucose from the blood, storing it as glycogen in the liver and muscle

*helps decrease blood glucose levels

*inhibits release of glucagon
Quinolones
Ex: ciprofloaxacin
DNA gyrase inhibitors are useful antibiotics; traps a ternary drug-topoisomerase-DNA complex, cellular processes convert into an irreversible letha DNA lesion ->apoptosis

Prevents religating of DNA so you have a permanent double strand break

*CANT TREAT ANTHRAX but can treat symptoms, deep infections


UTI, prostatis, gastroenteritis, nosocomial infections, STI’s
Etoposide & ciprofloxacin
Inhibits DNA re-ligation after strand translocation which also hinders replication
fluoroquinolone
Inhibits DNA gyrase, stopping strand unwinding and hindering replication
epipodophyllotoxins
Poison eukaryotic topo II

Drugs that interfere with eukaryotic topoisonmerases to prevent dna replication and act as anti-cancer agents

Cancer treatment, leukemia, lung,, testis, ovary
Camptothecin,
topotecan
-Poison eukaryotic topo I

fluoroquinolone
Drugs that interfere with eukaryotic topoisonmerases to prevent dna replication and act as anti-cancer agents

-Topotecan is active as a single agent in
Ovarian cancer, small-cell and non-small cell lung cancer, acute myelocytic leukemia, myelodysplastic syndromes
actinomycins
Prevents replication by preventing formation of regions of ssDNA, inhibits the action of topoisomerase II thereby preventing the removal of supercoils, inhibiting RNA transcription – cell replication requires the synthesis of specific RNA’s and protein at definite times in the cell cycle
Actinomycin D
Chemotherapy drug

Used for wilm tumor, rhabdomyosarcoma, Kaposi sarcoma, gestational trophoblastic tumors, testicular cancer
Tetracyclines:

Tetracycline, oxytetracyclin, doxycyclin, demeclocycline, lymecycline & minocycline
Family of broad spectrum of antibiotics;

Inhibits translation
Interacts with 30s and 40s small ribosomal subunits blocking access and therefore binding the amino-acyl tRNA to the A site


Effectiveness lies in that they are selectively concentrated by bacteria and NOT by mammalian cells
puromycin
Analogue of aminoacyl-tRNA, once incorporated into the growing peptide chain, it causes premature chain termination and elongation

Active in both eukaryotes and prokaryotes
chloramphenicol
Binds to 50s ribosomes and inhibits peptidyl transferase activity, prevents bond formation, and thus prevents elongation

This drug can be inactivated by chloamphenicol acetyltransferase produced by resistant strains
erythromycin
Inhibits translocation/elongation; binds irreversibly to 50s ribosome, blocks translocation by EF-G preventing elongation

Not effective against gram-negative bacteria; resistance can occur through plasmid controlled alteration of binding site for erythromycin on the ribosome; good for brain abcyss, gets deep into tissues
Streptomycin & aminoglycosides

Includes:
Gentamicin,
Amikacin,
Tobramycin,
Netilmicin,
neomycin
Binds to 30s subunit, distorting its structure, prevents binding of fmet-tRNA to the p-site of ribosomes, inhibits initiation – changes A to G in point mutation (polymorphism), higher affinity of aminoglycosides for the host mitochondrial ribosome, protein production in mitochondria is inhibited
Streptomycin and other aminoglycosides
Prevents binding of fmet-tRNA to the p site of ribosomes, causes midreading of mRNA
tetracyclines
Prevents aminoacyl-tRNAs beinding in the A site
chloramphenicol
Interferes with peptidyl transferase activity of the 50s ribosome, preventing peptide bond formation
erythromycin
Blocks translocation by binding to the 50s subunit of prokaryotes
puromycin
An analogue of aminoacyl-tRNA that causes premature chain termination
puromycin
An analogue of aminoacyl-tRNA that causes premature chain termination
disulfiram
Aversion therapy for alcoholism; how it works: acetaldehyde accumulates in tissues causing vomiting, hopefully leading to alcohol avoidance
aspirin
Inhibits cyclooxygenase (COX) enzymes irreversibly by acetylating the Ser530 OH group, which prevents arachiodonic acid from reaching the active site
statin
HMG CoA reductase inhibitors, lower cholesterol levels by stopping producting in the liver
Azidothymidine (AZT)
Nucleotide analogue of thymine, used in AIDS treatment; it inhibits viral reverse transcriptases but does NOT interact with human DNA polymerases
Captopril

1) Disorder/how drug treats it?
2) Symptoms of disorder/application?
1) Competitive inhibitor of the angiotensin converting enzyme (ACE) which is responsible for converting angiotensin I to angiotensin II; reduces hypertension (high blood pressure)

2)
allopurinol

1) Disorder/how drug treats it?
2) Symptoms of disorder/application?
1) Treats hyperuricemia (excess uric acid in blood) - cancer, gout, irreversible suicide inhibitor

2)
Ziduvudine

1) Disorder/how drug treats it?
2) Symptoms of disorder/application?
1) Utilized by viral reverse transcriptase, upon incorporation into d.s. DNA chain termination occurs due to lack of 3’OH

Doesn’t kill infection but prevents/decreases progression



Anti-viral Nucleoside analogues: Viral reverse transcriptase inhibitors

2) Prolongs life of HIV infected individuals, diminishes HIV associated dementia, reduce mother to baby transmission by more than 20%
Systemic Lupus Erythematosis

1) Disorder/how drug treats it?
2) Symptoms of disorder/application?
1) Autoimmune disease with multiple symptoms including extreme fatigue, arthritis, fever, skin rashes and kidney problems

2) Sufferers possess auto-antibodies that cross react with the U1 RNA component of the spliceosome
Beta-Thalassemia

1) Disorder/how drug treats it?
2) Symptoms of disorder/application?
1) Reduced synthesis of beta-hemoglobin chain that results in microcytic hypochromic anemia

2) Many of these mutations generate additional splice sites within the mRNA, as a result, frame shifts or premature stop codons are introduced into the mature mRNA, this results in production of an abnormal beta-globin protein
Limb girdle muscular dystrophy (LGMD)

1) Disorder/how drug treats it?
2) Symptoms of disorder/application?
1) Weakness and wasting restricted to the limb musculature

2) Patients possess a mutation in the caplain 3 gene that generates a new splice site within the exon 16 (coding sequence); this results in a shorter caplain 3 mRNA, missing exon 16 codons, produces a defective protein
