The d-homo androstane lactone 3β-hydroxy-17-oxa-d-homoandrost-5-en-16-one (I) was transformed through intermediate compounds 17-oxa-d-homoandrost-4-ene-3,16-dione (II) and/or 17-oxa-d-homoandrost-4-ene-3,6,16-trione (III) to 3(E),6(E)-dihydroximino-17-oxa-d-homoandrost-4-en-16-one (IV), which was characterized using analytical and spectral data. Compound IV was examined by X-ray crystallography, IR and NMR spectroscopy. Compound IV crystallized in a monoclinic system with a P21 space group. The dimensions of the unit cell are: a = 11.2815(5) Å; b = 13.1512(4) Å; c = 13.7145(8) Å; β = 110.890(5)°. The asymmetric unit cell consists of two symmetrically independent molecules (A and B) of 3(E),6(E)-dihydroximino-17-oxa-d-homoandrost-4-en-16-one and one methanol molecule. In the molecular structure of compound IV, two molecules in the asymmetric unit are connected by O–H···N hydrogen bonds, while the crystal packing of compound IV is predominantly organized by a dense network of O–H···O hydrogen bonds, mostly involving the O atom from the methanol molecule as donor or acceptor. Derivatives I–IV were screened for antitumor activity against six human cancer cell lines and one non-tumor cell line. The d-homo androstane lactone (3β-hydroxy-17-oxa-d-homoandrost-5-en-16-one) I was transformed through intermediate compounds 17-oxa-d-homoandrost-4-ene-3,16-dione (II) and/or 17-oxa-d-homoandrost-4-ene-3,6,16-trione (III) to 3(E),6(E)-dihydroximino-17-oxa-d-homoandrost-4-en-16-one (IV) which was characterized according to the analytical and spectral data. Compound IV was examined by X-ray crystallography, IR and NMR spectroscopy. Derivatives I–IV were screened for antitumor activity against six human cancer cell lines and one non-tumor cell line.
通过中间体 17-oxa-d-homoandrost-4-ene-3,16-dione (II) 和/或 17-oxa-d-homoandrost-4-ene-3,6,16-triione (III) 将 d-homo androstane lactone 3β-hydroxy-17-oxa-d-homoandrost-5-en-16-one (I) 转化为 3(E),6(E)-dihydroximino-17-oxa-d-homoandrost-4-en-16-one (IV),并利用分析和光谱数据对其进行了表征。化合物 IV 通过 X 射线晶体学、红外光谱和核磁共振光谱进行了检测。化合物 IV 以 P21 空间群的单斜体系结晶。单胞尺寸为:a = 11.2815(5) Å; b = 13.1512(4) Å; c = 13.7145(8) Å; β = 110.890(5)°。不对称单元胞由两个对称独立的 3(E),6(E)-二羟基亚氨基-17-氧杂-d-高雄甾-4-烯-16-酮分子(A 和 B)和一个甲醇分子组成。在化合物 IV 的分子结构中,不对称单元中的两个分子通过 O-H-N 氢键连接,而化合物 IV 的晶体堆积主要由密集的 O-H-O 氢键网络组成,其中大部分涉及甲醇分子中的 O 原子作为供体或受体。研究人员筛选了 I-IV 衍生物对六种人类癌细胞系和一种非肿瘤细胞系的抗肿瘤活性。d-homo androstane lactone (3β-hydroxy-17-oxa-d-homoandrost-5-en-16-one) I 通过中间化合物 17-oxa-d-homoandrost-4-ene-3,16-dione (II) 和/或 17-oxa-d-homoandrost-4-ene-3,6,16-triione (III) 转化为 3(E),6(E)-dihydroximino-17-oxa-d-homoandrost-4-en-16-one (IV),根据分析和光谱数据对其进行了表征。化合物 IV 通过 X 射线晶体学、红外光谱和核磁共振光谱进行了检测。筛选了 I-IV 衍生物对六种人类癌细胞系和一种非肿瘤细胞系的抗肿瘤活性。
