Nuclear magnetic resonance spectroscopy and mass spectrometry data for sulfated isoguanine glycosides.

The data presented here are related to the research paper entitled "Rare sulfated purine alkaloid glycosides from pupal case" [1]. In this data article, we provide 1D and 2D nuclear magnetic resonance (NMR) spectroscopy and electrospray ionization mass spectrometry (ESIMS) data of three undescribed sulfated purine alkaloids, locustoside A disulfate, saikachinoside B disulfate, and saikachinoside A trisulfate isolated from the pupal case of the wild bruchid seed beetle (Chrysomelidae, Bruchinae) infesting the seed of Miquel (Fabaceae).

HPLC profiles and spectroscopic data of cassane-type furanoditerpenoids.

The data presented here are related to the research paper entitled "Hydroxylated furanoditerpenoids from the pupal case produced by the bruchid beetle inside the seed of " (Akihara et al., 2018) [1]. In this data article, we provide high-performance liquid chromatography (HPLC) profiles of seven undescribed hydroxylated furanoditerpenoids, caesalsauteolide, 2-hydroxycaesaljapin, 2,7-dihydroxycaesaljapin, 2-hydroxycaesalacetal, caesalsauterol, 6-acetylcaesalsauterol, norcaesalsauterol isolated from the pupal cases produced by and four known compounds, caesaljaponin A (Kamikawa et al.

Hydroxylated furanoditerpenoids from pupal cases produced by the bruchid beetle Sulcobruchus sauteri inside the seeds of Caesalpinia decapetala.

Seven undescribed hydroxylated cassane-type furanoditerpenoids were isolated from pupal cases formed from the secretion/excretion of the larvae of the wild bruchid seed beetle Sulcobruchus sauteri in infested Caesalpinia decapetala seeds, and their structures were elucidated by interpreting their spectra. The hydroxylated furanoditerpenoids found in the pupal cases were not present in the seeds of the host plant. Caesalacetal and caesaljapin obtained from the intact seeds exhibited larvicidal activity against the larvae of Aedes albopictus, while the hydroxylated furanoditerpenoids isolated from the pupal cases were inactive.

Sulfated Purine Alkaloid Glycosides from the Pupal Case Built by the Bruchid Beetle Bruchidius dorsalis Inside the Seed of Gleditsia japonica.

Three new sulfated isoguanine alkaloid glycosides, designated as saikachinoside A monosulfate (1), saikachinoside A disulfate (2), and locustoside B disulfate (3), have been isolated from the pupal case of the wild bruchid seed beetle Bruchidius dorsalis (Chrysomelidae, Bruchinae) infesting the seed of Gleditsia japonica Miq. (Fabaceae). Their structures were determined by spectroscopic methods and the inhibitory activity of 2 and 3 against acid phosphatase was evaluated.

Prenylated purine alkaloids from seeds of Gleditsia japonica.

Three previously undescribed isoguanine glycosides with an N-prenyl group, designated locustoside B, saikachinoside B, and saikachinoside C, have been isolated from the seed of Gleditsia japonica Miquel (Fabaceae) along with two known compounds, locustoside A and saikachinoside A. Their structures were determined from spectroscopic data and X-ray crystallographic analysis. The inhibitory activity against acid phosphatase was evaluated.
