Synthesis of Aza-Surfactin and 3-Epi-Aza-Surfactin

HETEROCYCLES, 2012
Two synthetic approaches to aza surfactins are reported. In the first our recently developed synthesis of unnatural ß3 amino acids was used to prepare the requisite monomer which was used in solid phase peptide synthesis and followed by macrolactamization of a partially protected precursor. In the second the corresponding ß3 N hydroxyaminoacid was used

Interfacial properties of surfactin

Journal of Colloid and Interface Science, 1992
Abstract Surfactin is a lipopeptide produced by various strains of Bacillus subtilis and is a very powerful surfactant. Here we present the first report on the interfacial behavior of surfactin. The adsorption, Γmax, of surfactin at the interface of diluted solutions (5 × 10−8 to 5 × 10−7M) is around 3 × 1018 molecule m−2, a value indicating that ...

Hydrolysis of surfactin over activated carbon

Bioorganic Chemistry, 2019
Surfactin is obtained through biocatalysis by microorganisms. In our biorefinery concept, it is purified on activated carbon (AC) during downstream processing. Besides cyclic surfactin, it is possible to obtain linear surfactin analogues, when AC with specific properties is used.

Recent trends in the biochemistry of surfactin

Applied Microbiology and Biotechnology, 1999
The name surfactin refers to a bacterial cyclic lipopeptide, primarily renowned for its exceptional surfactant power since it lowers the surface tension of water from 72 mN m-1 to 27 mN m-1 at a concentration as low as 20 microM. Although surfactin was discovered about 30 years ago, there has been a revival of interest in this compound over the past ...

Surfactin variants for intra-intestinal delivery of insulin

European Journal of Pharmaceutics and Biopharmaceutics, 2017
Surfactin is a Bacillus-produced natural lipopeptide, which can overcome the epithelial cell barriers for orally delivering insulin, but its ability to promote uptake of insulin by the intestine need to be further improved for a higher oral bioavailability.
