Thymol

Thymol is a natural monoterpene phenol derivative of cymene, isomeric with carvacrol, found in oil of thyme, and extracted as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties. It has been used successfully to control varroa mites and prevent fermentation and the growth of mould in bee colonies. It has been used in alcohol solutions and in dusting powders for the treatment of tinea infections. It is the active antiseptic ingredient in the toothpaste Euthymol.

Properties Suppliers
Tigecycline

Tigecycline is a glycylcycline antibiotic. Tigecycline is bacteriostatic and is a protein synthesis inhibitor by binding to the 30S ribosomal subunit of bacteria and thereby blocking entry of Aminoacyl-tRNA into the A site of the ribosome during prokaryotic translation. Tigecycline is given intravenously and has activity against a variety of gram-positive and gram-negative bacterial pathogens, many of which are resistant to existing antibiotics.

Trichostatin A

Trichostatin A is an organic compound that serves as an antifungal antibiotic and selectively inhibits the class I and II mammalian histone deacetylase (HDAC) families of enzymes, but not class III HDACs. It inhibits the eukaryotic cell cycle during the beginning of the growth stage. It can be used to alter gene expression by interfering with the removal of acetyl groups from histones and therefore altering the ability of DNA transcription factors to access the DNA molecules inside chromatin. It is a member of a larger class of histone deacetylase inhibitors that have a broad spectrum of epigenetic activities. Thus, TSA has some potential as an anti-cancer drug. One suggested mechanism is that TSA promotes the expression of apoptosis-related genes, leading to cancerous cells surviving at lower rates, thus slowing the progression of cancer.

Tunicamycin

Tunicamycin is mixture of homologous nucleoside antibiotics that inhibits the UDP-HexNAc: polyprenol-P HexNAc-1-P family of enzymes. In eukaryotes, this includes the enzyme GlcNAc phosphotransferase (GPT), which catalyzes the transfer of N-actelyglucosamine-1-phosphate from UDP-N-acetylglucosamine to dolichol phosphate in the first step of glycoprotein synthesis. Tunicamycin blocks the synthesis of all N-linked glycoproteins and causes cell cycle arrest in G1 phase. It is used as an experimental tool in biology, e.g. to induce unfolded protein response. It is produced by several bacteria, including Streptomyces clavuligerus and Streptomyces Iysosuperficus.

Properties Suppliers
Valinomycin

Valinomycin is a dodecadepsipeptide antibiotic. It is obtained from the cells of several Streptomyces strains, among which "S. tsusimaensis" and S. fulvissimus. It is a member of the group of natural neutral ionophores because it does not have a residual charge. It consists of enantiomers D- and L-valine, D-hydroxyvaleric acid and L-lactic acid. Structures are alternately bound via amide and ester bridges. Valinomycin is highly selective for potassium ions over sodium ions within the cell membrane. It functions as a potassium-specific transporter and facilitates the movement of potassium ions through lipid membranes "down" an electrochemical potential gradient. The stability constant K for the potassium-valinomycin complex is 106 and for the sodium-valinomycin complex only 10. This difference is important for maintaining the selectivity of valinomycin for the transport of potassium ions in biological systems. It was recently reported to be the most potent agent against severe acute respiratory-syndrome coronavirus in infected Vero E6 cells. It acts as a nonmetallic isoforming agent in potassium selective electrodes.
