Tioguanine Action PathwayHomo sapiens
Tioguanine is an antineoplastic agent from the purine analog class. This drug also has antimetabolite action. Tioguanine is indicated for remission induction and remission consolidation in the treatment of acute nonlymphocytic leukemias. When this drug enters the cells, it competes with hypoxanthine and guanine for the hypoxanthine-guanine phosphoribosyltransferase (HGPRTase) and is itself converted to 6-thioguanilyic acid (TGMP), which reaches high intracellular concentrations at therapeutic doses. TGMP is a cytotoxic agent, it will interfere with the synthesis of guanine nucleotides by inhibiting the glutamine-5-phosphoribosylpyrophosphate aminotransferase (de novo pathway of purine ribonucleotide synthesis) enzyme by pseudofeedback. Furthermore, TGMP also inhibits the conversion of inosinic acid (IMP) to xanthylic acid (XMP) by competition for the enzyme IMP dehydrogenase. Thioguanine nucleotides are incorporated into both the DNA and the RNA. The final result is the sequential blockade of the usage and synthesis of purines, leading to apoptosis in the S phase of the cell cycle. This drug is administered as an oral tablet. An overdose of tioguanine may result in symptoms like nausea, vomiting, malaise, hypotension, and diaphoresis.

Tipranavir Action PathwayHomo sapiens
Tipranavir is a sulfonamide-containing dyhydropyrone and a nonpeptidic protease inhibitor used to treat HIV-1 resistant to more than 1 protease inhibitor. Protease inhibitors are almost always used in combination with at least two other anti-HIV drugs.
The HIV virus binds and penetrates the host cell. Viral RNA is transcribed into viral DNA via reverse transcriptase. Viral DNA enters the host nucleus and is integrated into the host DNA via integrase. The DNA is then transcribed, creating viral mRNA. Viral mRNA is translater into the gag-pol polyprotein. HIV protease is synthesized as part of the Gag-pol polyprotein, where Gag encodes for the capsid and matrix protein to form the outer protein shell, and Pol encodes for the reverse transcriptase and integrase protein to synthesize and incorporate its genome into host cells. HIV-1 protease cleaves the Gag-pol polyprotein into 66 molecular species, including HIV-1 protease, integrase, and reverse transcriptase. Tipranavir competitively binds to the active site of HIV-1 protease. This inhibition prevents the HIV virion from fully maturing and becoming infective. Using the lipid bilayer of the host cell, a virus is formed and released. The inhibition of HIV-1 protease prevents the necessary molecular species from forming, therefore preventing maturation and activation of viral particles. This forms immature, non-infectious viral particles, therefore, Tipranavir prevents the virus from reproducing.

Tirofiban ActionHomo sapiens
Tirofiban is a platelet aggregation inhibitor drug sold under the name Aggrastat. It is specifically a small molecule that inhibits the glycoprotein IIb/IIIa receptor of platelets. It is administered intravenously, and can act to decrease platelet aggregation by over 90% after the infusion, and can help prevent aggregation for up to two days after administration. In the vein, tirofiban causes a conformational change in the integrins on the surface of activated platelets. This prevents the binding of fibrinogen to these integrins, which in turn prevents the platelets from being held together by these fibrinogen fibres. The conformational change also prevents the binding of von Willebrand factor to the platelets, which also prevents aggregation and adhesion.
