Beauvericin is a cyclohexadepsipeptide mycotoxin which has insecticidal properties and which can induce apoptosis in mammalian cells. Beauvericin is produced by some entomo- and phytopathogenic Fusarium species.Beauvericin is a specific cholesterol acyltransferase inhibitor and is toxic to several human cell lines.It is a bioactive cyclodepsipeptide, which contains three D-a-hydroxy-isovaleryl and N-methyl-L-phenylalanyl residues in alternating sequence.

Blasticidin S

Blasticidin S is an antibiotic that is produced by Streptomyces griseochromogenes. In biological research, specifically genetic engineering, it is used to select transformed cells which have been engineered to carry a resistance gene for blasticidin. In short, DNA of interest is fused to DNA encoding a resistance gene, and then is transformed into cells. After allowing time for recovery and for cells to begin transcribing and translating their new DNA, blasticidin is added. Now only the cells that have the new DNA can grow.

Properties Suppliers
Brefeldin A

Brefeldin A is a lactone antibiotic produced by fungal organisms such as Eupenicillium brefeldianum. It inhibits transport of proteins from ER to Golgi and induces retrograde protein transport from the Golgi apparatus to the endoplasmic reticulum. This leads to proteins accumulating inside the ER. In mammalian and yeast cells, the main target of brefeldin A appears to be a certain type of GTP-exchange factors responsible for activating a GTPase called Arf1p ; in turn, Arf1p is involved in the formation of transport vesicles by recruiting coat proteins to intracellular membranes. Brefeldin A was initially isolated as an anti-viral antibiotic but is now primarily used in biological research to study protein transport.

Properties Suppliers

Calcimycin is a mobile ion-carrier that forms stable complexes with divalent cations. It is produced at fermentation of Streptomyces Chartreusensis. It has antibiotic properties against gram positive bacteria and fungi. It also acts as a divalent cation ionophore, allowing these ions to cross cell membranes, which are usually impermeable to them.

Caprylic Acid

Caprylic acid is the common name for the eight-carbon saturated fatty acid. It is found naturally in the milk of various mammals, and it is a minor constituent of coconut oil and palm kernel oil. It is used commercially in the production of esters used in perfumery and also in the manufacture of dyes. It is also used in the treatment of some bacterial infections. It is an antimicrobial pesticide used as a food contact surface sanitizer in commercial food handling establishments on dairy equipment, food processing equipment, breweries, wineries, and beverage processing plants. It is also used as disinfectant in health care facilities, schools/colleges, animal care/veterinary facilities, industrial facilities, office buildings, recreational facilities, retail and wholesale establishments, livestock premises, restaurants, and hotels/motels. In addition, caprylic acid is used as an algaecide, bactericide, and fungicide in nurseries, greenhouses, garden centers, and interiorscapes on ornamentals.

Carbenicillin is a bactericidal and bacteriolytic antibiotic belonging to the carboxypenicillin subgroup of the penicillins. It was discovered by scientists at Beecham. It has Gram-negative coverage which includes Pseudomonas aeruginosa but limited Gram-positive coverage. The carboxypenicillins are susceptible to degradation by beta-lactamase enzymes, although they are more resistant than ampicillin to degradation. It is a semi-synthetic analogue of the naturally occurring benzyl-penicillin. In molecular biology, carbenicillin may be preferred as a selecting agent because its breakdown results in byproducts with a lower toxicity than analogous antibiotics like ampicillin.
