  Synthesis and biological properties of chitin synthetase inhibitors resistant to cellular peptidases

  摘要：

  The synthesis and biological properties of seven polyoxins (4-10) designed to avoid peptidase hydrolysis in Candida albicans are presented. Five dipeptidyl and two tripeptidyl polyoxin analogues were synthesized by coupling an amino acid active ester or azlactone to uracil polyoxin C (2) or polyoxin D (1), subsequent removal of the protecting group, and purification by preparative HPLC. A new and novel route for introducing an n-propyl group onto the alpha-amino group of peptides is reported. With the exception of a carboxamide derivative, 8, all analogues were resistant to hydrolysis by a cell extract or permeabilized cells of Candida. Chitin synthetase inhibition constants were determined for 4-10 and the KI values ranged from 7.15 X 10(-6) M for octanoyl-phenylalanyl-polyoxin D (10) to 1.06 X 10(-3) M for D-tryptophanyl-uracil polyoxin C (6). These novel polyoxins do not compete with the transport of either peptides or uridine into the cell. Millimolar concentrations of compounds 4-10 are required to inhibit growth, cause morphological alterations, or reduce the viability of C. albicans.
