Source of material
The stems and roots of Sarcococcahookeriana (14.5 kg) collected from Hezhang country, Guizhou province, were extracted from methanol solution with ultrasonic radiation three times. The extract was concentrated and then partitioned between EtOAc and 1% aq. H2SO4. The acid-soluble fraction was alkalinized with aq. Na2CO3 to pH 9 and followed by exhaustive extraction with CH2Cl2 to afford crude alkaloids. The crude alkaloids were roughly divided into five fractions: Frs. A—E. Subsequently, fraction A was separated by silica gel column chromatography using petroleum ether/ethylacetate/diethylamine (50:1:1) as the eluent. The raw product was re-crystallized from dichloromethane to get the title compound as block colorless crystals.
Experimental details
The crystal structure was solved by direct methods and refined by full-matrix least-squares methods on F2 using Olex2 [2]. All hydrogen atoms were positioned geometrically, with the d(C—H) = 0.95−1.00 Å. The Uiso(H) were set to 1.2 times Ueq(C) for the methylene groups as well as methenyl groups, at 1.5 times Ueq(C) for the methyl groups.
Comment
The S.hookeriana possess a variety of bioactivity. A recently reported experimental study shows that the main chemical compositions of S.hookeriana are pregnane-type steroidal alkaloids [5]. These compounds have shown cholinesterase inhibition [6], and they poved antileishmanial [7], antibacterial [8] and estrogen biosynthesis-promoting [9] activities. As a folk prescription in miao area of guizhou province, S.hookeriana is used to treat Alzheimer’s diseases and other diseases.
The title compound crystallizes with one molecule in the asymmetric unit of the space group P212121 (the figure). Geometric parameters of the title structure are in the usual ranges [10]. The compound contains one amide group, one five-membered ring, three six-membered rings, one phenyl moiety and one dimethylamino group. The dimethylamino group was confirmed by the distance of 1.456(4) Å, 1.456(4) Å (C22—N1 and C23—N1), respectively. The amide group was confirmed by the distance of 1.235(4) Å, 1.461(4) Å, 1.349(4) Å (C25—O1, C24—N2 and C25—N2). The five-membered ring and three six-membered rings show intermolecular interactions by van der Waals forces only.
