Netilmicin
Netilmicin is a semisynthetic 1-N-ethyl derivative of sisomycin, an aminoglycoside antibiotic with action similar to gentamicin, but less ear and kidney toxicity. [PubChem] Netilmicin inhibits protein synthesis in susceptible organisms by binding to the bacterial 30S ribosomal subunit and interfering with mRNA binding and the acceptor tRNA site. The bactericidal effect of netilmiicin is not fully understood.

Ergonovine
Ergonovine is only found in individuals that have used or taken this drug. It is an ergot alkaloid with uterine and vascular smooth muscle contractile properties. [PubChem]Ergonovine directly stimulates the uterine muscle to increase force and frequency of contractions. With usual doses, these contractions precede periods of relaxation; with larger doses, basal uterine tone is elevated and these relaxation periods will be decreased. Contraction of the uterine wall around bleeding vessels at the placental site produces hemostasis. Ergonovine also induces cervical contractions. The sensitivity of the uterus to the oxytocic effect is much greater toward the end of pregnancy. The oxytocic actions of ergonovine are greater than its vascular effects. Ergonovine, like other ergot alkaloids, produces arterial vasoconstriction by stimulation of alpha-adrenergic and serotonin receptors and inhibition of endothelial-derived relaxation factor release. It is a less potent vasoconstrictor than ergotamine. As a diagnostic aid (coronary vasospasm), ergonovine causes vasoconstriction of coronary arteries.

Potassium
Potassium is an essential electrolyte. Potassium balance is crucial for regulating the excitability of nerves and muscles and so critical for regulating contractility of cardiac muscle. Although the most important changes seen in the presence of deranged potassium are cardiac, smooth muscle is also affected with increasing muscle weakness, a feature of both hyperkalaemia and hypokalaemia. Physiologically, it exists as an ion in the body. Potassium (K+) is a positively charged electrolyte, cation, which is present throughout the body in both intracellular and extracellular fluids. The majority of body potassium, >90\\%, are intracellular. It moves freely from intracellular fluid (ICF) to extracellular fluid (ECF) and vice versa when adenosine triphosphate increases the permeability of the cell membrane. It is mainly replaced inside or outside the cells by another cation, sodium (Na+). The movement of potassium into or out of the cells is linked to certain body hormones and also to certain physiological states. Standard laboratory tests measure ECF potassium. Potassium enters the body rapidly during food ingestion. Insulin is produced when a meal is eaten; this causes the temporary movement of potassium from ECF to ICF. Over the ensuing hours, the kidneys excrete the ingested potassium and homeostasis is returned. In the critically ill patient, suffering from hyperkalaemia, this mechanism can be manipulated beneficially by administering high concentration (50\\%) intravenous glucose. Insulin can be added to the glucose, but glucose alone will stimulate insulin production and cause movement of potassium from ECF to ICF. The stimulation of alpha receptors causes increased movement of potassium from ICF to ECF. A noradrenaline infusion can elevate serum potassium levels. An adrenaline infusion, or elevated adrenaline levels, can lower serum potassium levels. Metabolic acidosis causes a rise in extracellular potassium levels. In this situation, excess of hydrogen ions (H+) are exchanged for intracellular potassium ions, probably as a result of the cellular response to a falling blood pH. Metabolic alkalosis causes the opposite effect, with potassium moving into the cells. (PMID: 17883675) [HMDB].

Phycocyanobilin
Phycocyanobilin is a linear, open-chain tetrapyrrole pigment that belongs to the family of bilins. It serves as a chromophore in various phytochrome photoreceptors found in cyanobacteria, as well as in the chlorosomes of green sulfur bacteria. Phycocyanobilin is a key component of phycobiliproteins, which are water-soluble pigments involved in light harvesting during photosynthesis. **Chemical Structure:** Phycocyanobilin has a molecular formula of C33H36N4O6 and a molecular weight of approximately 596.67 g/mol. Structurally, it consists of a porphyrin backbone with four pyrrole rings connected by methine bridges. The pyrrole rings contain nitrogen atoms that coordinate a central magnesium ion in phycobiliproteins. Unlike chlorophyll, phycocyanobilin has an open-chain structure due to the presence of a double bond between the C-20 and C-21 positions of the macrocyclic ring, which prevents it from forming a fully circular porphyrin ring. **Properties:** - **Color:** Phycocyanobilin imparts a blue color to the phycobiliproteins in which it is bound. The specific color is due to the electronic structure of the phycocyanobilin molecule, which allows it to absorb light in the red region of the visible spectrum, typically around 620-630 nm. - **Solubility:** Unlike many other pigments, phycocyanobilin is water-soluble due to its binding to phycobiliproteins, which enhances its functionality in the thylakoid membranes of cyanobacteria. - **Chemical Reactivity:** Phycocyanobilin can be isomerized and oxidized to form other bilins, such as phycoerythrobilin and phycourobilin, which have different spectral properties and can be found in different phycobiliproteins. **Biological Role:** Phycocyanobilin plays a critical role in the photosynthetic process of cyanobacteria and certain green sulfur bacteria. Its primary functions include: - **Light Harvesting:** In phycobiliproteins like phycocyanin, phycocyanobilin serves as a light-harvesting antenna. It absorbs light energy and transfers it to the photosynthetic reaction centers, where it is used to drive the synthesis of ATP and NADPH. - **Photoregulation:** In cyanobacteria, phycocyanobilin is also involved in the regulation of photosynthesis through the action of phytochrome-like photoreceptors. These photoreceptors can switch between a Pr (red-absorbing) and a Pfr (far-red-absorbing) form in response to light, regulating gene expression and various metabolic processes. **Synthesis:** Phycocyanobilin is synthesized from the amino acid L-arginine through a series of enzymatic reactions that include the production of 5-aminolevulinic acid (ALA), which is then transformed into protoporphyrin IX. The protoporphyrin IX is subsequently modified to form phycocyanobilin, a process that involves the removal of the macrocyclic ring and the introduction of the double bond at the C-20 and C-21 positions. In summary, phycocyanobilin is an essential pigment for the photosynthetic apparatus of certain photosynthetic organisms, contributing to their ability to capture and utilize light energy for the production of organic compounds. Its unique structure and properties allow it to perform a variety of functions that are critical to the survival and ecological success of these organisms.
Carboprost Tromethamine
Carboprost Tromethamine is only found in individuals that have used or taken this drug. It is a nonsteroidal abortifacient agent that is effective in both the first and second trimesters of pregnancy. [PubChem]Carboprost is a synthetic prostaglandin. It binds the prostaglandin E2 receptor, causing myometrial contractions, casuing the induction of labour or the expulsion of the placenta. Prostaglandins occur naturally in the body and act at several sites in the body including the womb (uterus). They act on the muscles of the womb, causing them to contract.

Proflavine
Proflavine is only found in individuals that have used or taken this drug. It is a topical antiseptic used mainly in wound dressings. [PubChem]Proflavine acts by interchelating DNA (intercalation), thereby disrupting DNA synthesis and leading to high levels of mutation in the copied DNA strands. This prevents bacterial reproduction. C254 - Anti-Infective Agent > C28394 - Topical Anti-Infective Agent D000890 - Anti-Infective Agents

Ergonovine
A monocarboxylic acid amide that is lysergamide in which one of the hydrogens attached to the amide nitrogen is substituted by a 1-hydroxypropan-2-yl group (S-configuration). An ergot alkaloid that has a particularly powerful action on the uterus, its maleate (and formerly tartrate) salt is used in the active management of the third stage of labour, and to prevent or treat postpartum of postabortal haemorrhage caused by uterine atony: by maintaining uterine contraction and tone, blood vessels in the uterine wall are compressed and blood flow reduced.
