Depsipeptide inhibits removal of incorporated 5-aza-CdR from DNA.

open access: yes, 2013
(A) H719 cells were incubated with [3H]-5-aza-CdR for 48 hrs, with presence or absence of depsipeptide at 0.1 µM for the first 6 hrs (depsipeptide+[3H]-5-aza-CdR) or last 6 hrs ([3H]-5-aza-CdR+depsipeptide) and then washed with cold PBS.

Effective Synthesis and Antifouling Activity of Dolastatin 16 Derivatives

open access: yesMarine Drugs, 2022
Some derivatives of dolastatin 16, a depsipeptide natural product first obtained from the sea hare Dolabella auricularia, were synthesized through second-generation synthesis of two unusual amino acids, dolaphenvaline and dolamethylleuine.
