Supply Raw Material Powder CAS 1405-97-6 Gramicidin
Gramicidin is a heterogeneous mixture of three antibiotic compounds, gramicidins A, B and C, making up 80%, 6%, and 14%, respectively, all of which are obtained from the soil bacterial species Bacillus brevis and called collectively gramicidin D. Gramicidin D contains linear pentadecapeptides, that is chains made up of 15 amino acids. This is in contrast to gramicidin S, which is a cyclic peptide chain.
The product is white and light yellow crystalline powder. Odorless. Melting point ≥ 229 ºC. Soluble in ethanol, acetic acid; insoluble in water, ether. Thermal stability, the UV absorption peak of 271,231.5,290.5nm. Not easily digested by protease, but can be acid hydrolysis.
Gramicidin is a lipophilic substance, the two short bacitracinmolecules are dimer to the left helix space configuration, constitute a cross-lipid membrane membrane channel to combine and carry a specific cation from the side of the membrane into the channel and then spread to The other side of the membrane, so there is the name of ion s, so that the cell metabolism can not be normal and inhibited or even death. They have a significant effect on Gram-positive bacteria.
On the Bacillus anthracis, Clostridium perfringens, pneumococcus and golden yellow pus micrococcus and so have a good antibacterial effect.
Take gramicidin A as an example. Because it is a fat-soluble substance, two gramicidins
The molecular dimer is in a left-hand helix spatial configuration, forming a channel across the bilayer lipid membrane membrane to bind and carry specific cations from one side of the membrane into the channel and then diffuse to the other side of the membrane, so there is an ion . Said, so that cell metabolism can not be normal and suppressed or even died.
They have a significant effect on gram-positive bacteria. It has good antibacterial activity against Bacillus anthris, Clostridium perfringens, Diplococcus pneumoniae and Micrococcus pyogenes Var. aureus. Only at high concentrations does it have an inhibitory effect on certain gram-negative bacteria.
General ointment formulations for the prevention and treatment of skin purulent disease.
