1H-NMR and 13C-NMR dataset for some oxidative metabolites of CRA13 and their analogs.

CRA13 (CB-13; SAB-378) is a dual CB1R/CB2R agonist cannabinoid agent developed by Novartis Pharma. Upon administration, it undergoes metabolism to oxidative metabolites. Herein, the 1H-NMR and 13C-NMR dataset of some oxidative metabolites and analogs thereof are presented for further analysis and comparison purposes, for whom may be interested.

Value of the data

CRA13 (CB-13; SAB-378) is a controlled cannabinoid substance in China and therefore a reference data for its metabolites are required.

The presented data provides reference that might be useful for detection of metabolites of CRA13 and related cannabinoids in biological samples.

In addition. It might be helpful in the assignment of signals of molecules containing di(naphthalen-1-yl)methanone moiety.

Also, the shown splitting and chemical shifts is helpful to structural analysis of related cannabinoids.

Data

The data presented herein describe the acquired for 1H-NMR and 13C-NMR spectra of hydroxy and carboxy metabolites of CRA13, as well as, methyl ester and analogs of the hydroxy, carboxy and methyl ester [1], [2]. Thus, a total of eight compounds were chemically synthesized and NMR data of pure samples were acquired in deuterated chloroform or deuterated methanol. These data might be useful for detection of metabolites of these controlled cannabinoids compounds and for structural assignment of compounds possessing di(naphthalen-1-yl)methanone moiety. The data are presented as figures with enlargement of proton peaks to clarify their splitting pattern.

Experimental design, materials, and methods

The compounds were chemically synthesized and purified by column chromatography as described in [1]. The samples were dissolved in CDCl3 or CD3OD then NMR spectra were acquired using a Brucker Avance 400 spectrometer (400 MHz) for 1H-NMR or Agilent 500 spectrometer (125 MHz) for 13C-NMR at 25 °C. The NMR peaks of the acquired NMR spectra are shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16.
