Unusual intramolecular hydrogen bonding in cycloamanide A, cyclic (LPro-LVal-LPhe-LPhe-LAla-Gly). A crystal structure analysis.
TLDR
The naturally occurring cyclic hexapeptide, cycloamanide A, has only one intramolecular hydrogen bond and the conformation of the molecule was established by a crystal structure determination using X-ray diffraction analysis. Expand
Crystal structure of the 1:1 mixture of cyclic (L-Ala-L-Pro-L-Phe-L-Pro) and cyclic (L-Ala-L-Pro-D-Phe-L-Pro).

TLDR
The conformation of the synthetic cyclic tetrapeptide Ala-Pro-Phe-Pro, C22H28N4O4, was established by X-ray diffraction methods and the two independent molecules in the asymmetric unit were found to be diastereoisomers. Expand
On the non-stoichiometry of the binding of Pt(II) anti-neoplastic agents to inosine 5'-monophosphate.
TLDR
Preliminary studies on the Pt(II)-5′-IMP complex, synthesized in the laboratories, demonstrate that the complex is indeed stoichiometric. Expand
