Synthesis of tyrosine derivatives for saframycin MX1 biosynthetic studies
摘要:
Saframycin MX1 and structural relatives are natural anticancer agents isolated from bacteria and marine invertebrates. For biosynthetic studies and to make a library of modified natural products, a series of tyrosine derivatives were synthesized in a concise manner. (C) 2004 Elsevier Ltd. All rights reserved.

The natural product pepticinnamin E potently inhibitsprotein farnesyl transferases and has potential applications in treating cancer and malaria. Pepticinnamin E contains a rare N-terminal cinnamoyl moiety as well as several nonproteinogenic amino acids, including the unusual 2-chloro-3-hydroxy-4-methoxy-N-methyl-L-phenylalanine. The biosynthesis of pepticinnamin E has remained uncharacterized because

The O-methylation of 3, 4-dihydrcxyphenylalanine with rat liver homogenate was investigated in the presence of S-adenosylmethionine and MgCl2 in vitro. By catechol-O-methyltransferase, it was found that 3, 4-dihydroxyphenylalanine was methylated to 3-hydroxy-4-methoxyphenylalanine.
