Beskrivning: Trimethoprim is an antibacterial agent; a specific inhibitor of formylation; a dihydrofolate reductase inhibitor.
Trimethoprim is primarily used as an antibacterial agent. It has dihydrofolate reductase inhibitor activity with selectivity for the prokaryote enzyme. It is used to treat urinary tract infections, mild acute prostatitis, recurrent cystitis, asymptomatic bacteriuria during pregnancy and respiratory tract infections.
The combination of trimethoprim and sulfamethoxazole interferes with the cellular metabolism of folic acid in the bacterial cell by blocking the biosynthesis of nucleotides. Trimethoprim binds to dihydrofolate reductase and inhibits the reduction of dihydrofolic acid (DHF) to tetrahydrofolic acid (THF). THF is an essential precursor in the thymidine synthesis pathway and interference with this pathway inhibits bacterial DNA synthesis.

Beskrivning: Trehalose Dihydrate is an osmolyte, a chemical chaperone. It contains many properties that allow it to stabilize partially unfolded protein molecules and inhibit protein aggregation. It include a low chemical reactivity, high glass transition temperature, existence of numerous polymorphs, nonreducing nature, and high affinity for water molecules. Additionally, Trehalose has been noted to bind to expanded polyglutamines and stabilize partially unfolded polyglutamine-containing proteins.

Glutathione is the major low molecular weight thiol compound of the living plant or animal cell. It is a tripeptide with a gamma peptide linkage between the amine group of cysteine (which is attached by normal peptide linkage to a glycine) and the carboxyl group of the glutamate side-chain. It is an antioxidant, preventing damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides. The sulfhydryl (thiol) group (SH) of cysteine serves as a proton donor and is responsible for the biological activity of glutathione.
Glutathione suppresses human immunodeficiency virus expression in chronically infected monocytic cells. It is a useful tripeptide involved in many aspects of metabolism, including transport of g-glutanyl amino acids and reductive cleavage of disulfide bonds.
Endogenous antioxidant that plays a major role in reducing reactive oxygen species formed during cellular metabolism and the respiratory burst. Glutathione-S-transferase catalyzes the formation of glutathione thioethers with xenobiotics, leukotrienes, and other molecules that have an electrophilic center. Glutathione also forms disulfide bonds with cysteine residues in proteins. Via these mechanisms, it can have the paradoxical effect of reducing the efficacy of anti-cancer agents.

Beskrivning: D-(+)-Maltose monohydrate is a component of starch and glycogen. It is a sugar composed of 2 α-D-glucose molecules coupled by an α(1→4) glycosidic bond. It is a reducing sugar with one anomeric carbon not linked in an anomeric bond. It contains a hemiacetal function and can mutarotate. Maltose is one product generated from starch and glycogen by the action of α-amylase.

Beskrivning: Potassium Iodide is known as Potassium Salt of Hydriodic Acid [HI], available in white crystalline powder form. It is a mild reducing agent and can be easily oxidized to Iodine by powerful oxidizing agent like chlorine. With elemental iodine it forms I3 (tri iodide), the salts of tri iodide are highly water soluble.
Readily soluble in water.

Beskrivning: Diamide is used as a thiol oxidising agent. It has also been used to titrate protein glutathiolation to discriminate from other oxidative protein modifications. Diamide treatment increased protein glutathiolation in a concentration-dependent manner and had comparably little effect on protein-protein disulphide formation.
