These compounds can be derived from naturally occurring peptides, such as those selected from colistin, circulin A, polymyxin A, polymyxin B, polymyxin D, octapeptin B, octapeptin C, and [lle7]polymyxin B1.
Provided herein are novel compounds and novel protected compounds that can be derived from polymyxin, including, e.g., polymyxin Bi and [lie7] polymyxin Bi.
The polymyxine B base is converted by mineral acid to polymyxine B salt solution, from which is obtained crystal substance by drying.
The polymyxin synthetase of the present invention can be effectively used for the increase of productivity of polymyxin and the development of a novel antibiotic.
The polymyxine B is eluated from adsorbent by aqueous solution of organic solvent.
A pharmaceutical formulation comprising Bacitracin or a pharmaceutically acceptable derivative thereof, Polymyxin or a pharmaceutically acceptable derivative thereof and an antiseptic.
The invention is related to the method of polymyxine B recovery from fermentation broth for the purpose of pure substance recovery.
Surface acting agents such as benzalkonium chloride or polymyxin B sulfate or both may be utilized.
In some embodiments, the antimicrobial agent is an antimicrobial peptide such as a polymyxin, for example but not limited to colistin.
Also provided are genetically modified members of the genus Paenibacillus that have been genetically modified to not produce an antimicrobial, for instance, a polymyxin E.
The antibiotics include about 10,000 IU of polymyxin B sulfate, and about 5 mg neomycin per gram of gel.
The present invention provides novel liposomal formulations of polymyxin B and pharmaceutical compositions thereof useful for the treatment of bacterial infections.
The liposomal formulation comprises a lipid component formed as vesicles each having a minimum size of at least 500 nm and polymyxin B encapsulated in the vesicles.
The present invention relates to an improved MCCDA culture medium composition comprising a high concentration of polymyxin B, and to a method for producing same.
The fuivic acid can be provided in combination with one or more antibiotics from the class of carbapenems or polymyxin antibiotics.
