Office of Biological and Environmental Research, through
Contract DE-AC02-05CH11231 between Lawrence Berkeley
National Laboratory and the U.S. Department of Energy. We
thank Dr. Antonio DiPasquale (UC Berkeley) for solving the
crystal structure of (R)-2·HCl and determining its absolute
stereochemistry (Supported by NIH Shared Instrumentation
Grant S10-RR027172). We acknowledge the CYLView
program (developed by Prof. Claude Y. Legault, Dept. of

occurring as a mixture of atropisomers; 7′S anti is the major one in a
(
ratio of 88:7, 7′(S)-anti/7′(S)-syn.
(16) In addition to Pseudalteromonas rubra, cycloprodisiosin is also
produced by Pseudoalteromonas dentrificans and Vibrio gazogenes. See

8) Obatoclax is believed to inhibit protein−protein binding
interactions between the Bcl-2 antiapoptotic family of proteins and
the Bax family of pro-apoptotic proteins, thus promoting apoptosis of
malignant cells that have undergone a mutation to prevent apoptosis.
