Sb. Singh et al., Structure, histone deacetylase, and antiprotozoal activities of apicidins B and C, congeners of apicidin with proline and valine substitutions, ORG LETT, 3(18), 2001, pp. 2815-2818
Isolation and structure elucidation of two novel cyclic tetrapeptides that
show a variety of potent antiprotozoal activities by reversibly inhibiting
HDAC have been reported. These are the new members of a unique family of cy
clic tetrapeptides that do not require the electrophilic alpha -epoxyketone
moiety of HC-toxin, trapoxin A, or chlamydocin for their potent activities
against HDAC and the malarial parasite.
