Embodiment 1

[0024] The preparation of embodiment 1 dehydroepiandrosterone acetone azine (1)

[0025] Step 1: the preparation of dehydroepiandrosterone hydrazone

[0026] Weigh 3.0g of dehydroepiandrosterone and place it in a 100mL round bottom flask, add 40mL of absolute ethanol, stir at room temperature to dissolve completely, then raise the temperature to 45°C, add 4mL of 85% hydrazine hydrate, stir for 2 hours, TLC traces that the raw material point disappears Afterwards, the reaction was terminated, and a white powdery solid was precipitated by distillation under reduced pressure, which was recrystallized from methanol to obtain 2.1 g of a white powder. m.p: 190-192°C. The structure of the product was confirmed by IR, NMR and MS analysis.

[0027] Step 2: the preparation of dehydroepiandrosterone acetone azine (1)

[0028] Weigh 120 mg of dehydroepiandrosterone hydrazone and place it in a 100 mL round bottom flask, add 30 mL of absolute ethanol, stir, add 1 mL of acetone after compl...

Embodiment 2

[0029] The preparation of embodiment 2 dehydroepiandrosterone benzaldehyde azine (2)

[0030] Weigh 60 mg of dehydroepiandrosterone hydrazone, add 25 mL of absolute ethanol, stir at room temperature to dissolve completely, then add 23 mg of benzaldehyde, raise the temperature to 50 degrees, stir for 2 hours, TLC traces that the raw material point basically disappears, terminate the reaction, and depressurize Distill to near dryness, add 15mL water, 15mL ethyl acetate, move into a separatory funnel and extract three times, the organic phase is dried over anhydrous sodium sulfate, and separated by plate chromatography after vacuum distillation. Add petroleum ether with ethyl acetate in a volume ratio of 1: 1.6 was used as the mobile phase to obtain 67 mg of white powder solid with a yield of 86%. m.p: 62-63°C; the structure of the product was confirmed by IR, NMR and MS analyses.

Embodiment 3

[0031] The preparation of embodiment 3 dehydroepiandrosterone-3-pyridylaldehyde azine (3)

[0032] Weigh 100mg of dehydroepiandrosterone hydrazone, put it in a 100mL round bottom flask, add 25mL of absolute ethanol, add 35mg of 3-pyridinecarbaldehyde after completely dissolving at room temperature, raise the temperature to 40°C and stir for 3 hours, TLC tracking, the raw material point is basically After the disappearance, the reaction was terminated. After distillation under reduced pressure, recrystallization was performed with a mixed solvent of ethyl acetate and petroleum ether to obtain 96 mg of light yellow crystals, with a yield of 70%, m.p: 195-197°C; the structure of the product was determined by IR, NMR and MS analysis.

Abstract

The invention relates to a dehydroepiandrosterone aromatic aldehyde azine steroidal compound with an azine structure. The chemical structural formula is as shown by dehydroepiandrosterone acetone azine (1), dehydroepiandrosterone benzaldehyde azine (2), dehydroepiandrosterone-3-pyridylaldehyde azine (3), dehydroepiandrosterone-3-thiophenecarboxaldehyde azine (4), dehydroepiandrosterone-3-hydroxybenzaldehyde azine (5), dehydroepiandrosterone-2-naphthaldehyde azine (6), dehydroepiandrosterone-4-quinolinecarboxaldehyde azine (7) and dehydroepiandrosterone-6-methoxy-naphthaldehyde azine (8) described in the specification. Experiments prove that the dehydroepiandrosterone aromatic aldehyde azine steroidal compound has an obvious inhibitory effect on various tumor cell strains, and can be applied to preparation of drugs for treating cancers.

Description

1. Technical field [0001] The invention relates to a class of dehydroepiandrosterone aromatic aldehyde azine steroid compound, its synthesis method and its application in the preparation of antitumor drugs. 2. Background technology [0002] Azine and its derivatives are an important class of compounds. It has been reported in the literature that azine compounds are widely used in the fields of biomedicine and pesticides, and they have extensive research value in the development of antibacterial, insecticidal and antitumor drugs. In the research on the synthesis of azine compounds, Chinese patent CN200580028484.X once reported a class of azine-carboxamide compounds used as anticancer drugs. Meanwhile, in the synthesis of steroidal azine compounds, a class of 6-carbonylcholestane thiazolidinone azine compounds (Salman Ahmad Khan, Abdullah M. Asiria, Mohammed Yusuf. Synthesis and biological evaluation of some thiazolidinone derivatives of steroid asantibacterial agents, Europ...
