Sumatriptan Mechanism of Action Action Pathway

Homo sapiens
Triptans are a class of medications used in the treatment of migraine headaches. Triptans act as antimigraine agents by selectively binding to the serotonin receptors 5-HT1B and 5-HT1D. Triptan binding to the vascular 5-HT1B receptors leads to vasoconstriction of the cranial arteries, which painfully dilate during a migraine attack. Sumatriptan is a 5-HT1B/1D receptor agonist and leads to vasoconstriction in the basilar artery and the blood vessels of the dura mater. It decreases peripheral nociception either by selective cranial vasoconstriction or an effect on trigeminovascular nerves. The blocking effect of sumatriptan indicated a peripheral effect on trigeminal vascular nerves in neurogenically mediated plasma extravasation. Sumatriptan inhibits the presynaptic terminal of the trigeminal nucleus caudalis, which leads to the reversal of facial allodynia. Triptans decrease transmission of the pain impulses to the trigeminal nucleus caudalis and reduce inflammatory mediators from trigeminal nerves, therefore reducing calcitonin gene-related peptide-mediated vasodilation. Migraine pain is associated with middle cerebral artery dilatation, which leads to a lower velocity of regional cerebral blood flow. Sumatriptan reverses the dilatation of MCA, which suggests that the 5-HT receptor system has a role in the pathogenesis of a migraine.

Sunitinib Action Pathway

Homo sapiens
Sunitinib is a chemotherapeutic agent and receptor tyrosine kinase inhibitor utilized in the treatment of renal cell carcinoma (RCC) and imatinib-resistant gastrointestinal stromal tumor (GIST). Approved by the US FDA on January 26, 2006, it's administered orally and operates as a multi-targeted small-molecule receptor tyrosine kinase (RTK) inhibitor. Its actions encompass inhibiting key signaling pathways by targeting various RTKs, including platelet-derived growth factor receptors (PDGF-R), vascular endothelial growth factor receptors (VEGF-R), and KIT (CD117) in GIST cases. Sunitinib also affects RET, CSF-1R, and flt3 RTKs. Indicated conditions for sunitinib include advanced RCC, adjuvant treatment post-nephrectomy for high-risk recurrent RCC, and well-differentiated pancreatic neuroendocrine tumors (pNET) with unresectable locally advanced or metastatic disease. Its mechanism entails inhibiting RTKs implicated in cancer progression, tumor growth, and angiogenesis. This inhibition encompasses PDGFRa, PDGFRb, VEGFR1, VEGFR2, VEGFR3, KIT, FLT3, CSF-1R, and RET receptors. The primary metabolite mirrors sunitinib's potency in relevant assays.

Superoxide Radicals Degradation

Escherichia coli
In gram-negative bacteria, cytoplasmic and periplasmic isozymes of superoxide dismutase (SOD) is their defense system against superoxide anion (O2-). In E.coli, there are several SOD isozymes which are manganese-cofactored (MnSOD), iron-cofactored (FeSOD) and copper, zinc-cofactored (CuZnSOD) in perplasm, and they can be generated by autooxidation of dihydromenaquinone in the cytoplasmic membrane. In E.coli, MnSOD and FeSOD have similar structure and kinetic, but CuZnSOD is monomeric. FeSOD is the only SOD in E.coli under anaerobic conditions. MnSOD is induced by environmental stress condition as well as aerobic growth. CuZnSOD is induced in stationary phase. SOD will catalyze the superoxide anion to form oxygen and H2O2. With increasing concentration of H2O2, catalase such as cryptic adenine deaminase is induced in E.coli to degrade H2O2 into water and oxygen.
