The antibiotic icosapeptide trichosporin B-V, which was isolated fromTrichodermapolysporum, was synthesized by assembling five peptide fragments via the N,N'-dicyclohexylcarbodiimide method. The synthesized peptide was identical with the natural one.
A membrane-modifying peptideantibiotic having uncoupling activity on rat liver mitochondria, hypelcin A-III, has been synthesized by assembling five peptide fragments via the N,N'-dicyclohexylcarbodiimide method. The synthesized hypelcin A-III was identical with the natural product.
