Ramalho, Suelem D. published the artcileSynthesis, racemic X-ray crystallographic, and permeability studies of bioactive orbitides from Jatropha species, HPLC of Formula: 77128-73-5, the publication is Journal of Natural Products (2018), 81(11), 2436-2445, database is CAplus and MEDLINE.

Orbitides are small cyclic peptides with a diverse range of therapeutic bioactivities. They are produced by many plant species, including those of the Jatropha genus. Here, the objective was to provide new structural information on orbitides to complement the growing knowledge base on orbitide sequences and activities by focusing on three Jatropha orbitides: ribifolin, pohlianin C, and jatrophidin. To determine three-dimensional structures, racemic crystallog., an emerging structural technique that enables rapid crystallization of biomols. by combining equal amounts of the two enantiomers, was used. The high-resolution structure of ribifolin (0.99 Å) was elucidated from its racemate and showed it was identical to the structure crystallized from its L-enantiomer only (1.35 Å). Racemic crystallog. was also used to elucidate high-resolution structures of pohlianin C (1.20 Å) and jatrophidin (1.03 Å), for which there was difficulty forming crystals without using racemic mixtures The structures were used to interpret membrane permeability data in PAMPA and a Caco-2 cell assay, showing they had poor permeability. Overall, the results show racemic crystallog. can be used to obtain high-resolution structures of orbitides and is useful when enantiopure samples are difficult to crystallize or solution structures from NMR are of low resolution
