Description

LYCOLINE /-ARYL ACRYLATE DERIVATIVES, PREPARATION METHOD AND APPLICATION THEREOF TECHNICAL FIELD
The application relates to the field of biomedicine, in particular to a lycoline P-aryl
acrylate derivative, a preparation method and application thereof.
BACKGROUND
The information disclosed in the background of the application is intended to
enhance the understanding of the overall background of the application, and the
disclosure should not necessarily be regarded as an acknowledgement or in any form
implying that the information has become prior art known to those of ordinary skill in
the art.
In recent years, the incidence and mortality of tumors have been on the rise, and
malignant tumors are seriously threatening human health and life safety. According to
statistics, more than 14 million people worldwide suffer from tumors each year, and
tumors are currently the second cause of death in the world. Traditional tumor treatment
uses a combination of radiotherapy and chemotherapy, which causes greater damage to
normal cells, and patients will have many adverse reactions in the middle and late stages,
which will cause the disease to further aggravate. Therefore, it is particularly important
to find new tumor treatment targets and develop new tumor treatment drugs. Compared with traditional drugs, small-molecule targeted drugs have the advantages of fewer side effects, higher specificity and higher efficacy, and are currently the research hotspots of anti-tumor medicines. Traditional Chinese medicine has obvious advantages in the treatment of malignant tumors because of its mild effect, good therapeutic effect and few adverse reactions. In recent years, the extraction of effective antineoplastic compounds from natural drugs is an important research direction for the development of new antineoplastic drugs.
Lycorine is a kind of alkaloid isolated from the bulb of traditional Chinese
medicine Lycoris radiata, which has good antiviral, anti-inflammatory and anti-tumor
activities and has a variety of mechanisms. As early as 1976, Jimenez et al. discovered
the anti-tumor activity of lycorine for the first time. Lycoline and its derivatives have
varying degrees of inhibitory effects on leukemia (K562, HL-60, L-1210), bladder
cancer (T24), prostate cancer (PC-3, DU145, LNCaP, 22RV1, CRPC), ovarian cancer
(Hey1B), lung cancer (A549, H460), esophageal cancer (Eca-109), multiple myeloma
(KM3, ARH-77), gastric cancer (hGCC), hepatic cancer (HCC), kidney cancer (786-0)
and other malignant tumors. A large number of studies have shown that lycoline can
induce tumor cell apoptosis, regulate tumor cell cycle, affect tumor cell autophagy, and
inhibit tumor cell invasion and metastasis by regulating most tumor molecular targets
and signal pathways.

preparation method and appliction thereof. According to the lycorine p-aryl acrylate

a: 2-tert-butyldimethylsilyl-lycorine, i.e., INB (10.0 mmol) and 3-(1-naphthyl)
1470 acrylic acid (12.0 mmol) were dissolved in 50 mL of dichloromethane in a 250 mL
round-bottom reaction flask and EDCI.HCl (18.0 mmol), DMAP (1.0 mmol) were
added successively at room temperature under nitrogen. After the addition, the reaction
was kept at the temperature of 35 °C and stirred. The residual quantity of INB was
traced and detected by HPLC, when it was less than 8 percent, post-treatment was
1475 performed. The reaction solution was washed once with 100 mL of purified water and
100 mL of 10% sodium chloride solution in turn, and then concentrated under reduced
pressure for later use.
b: the above product dissolved in 50 mL absolute ethanol in a 250 mL
round-bottom reaction flask, and 5.0 mL concentrated HCl was slowly added dropwise
1480 with stirring at room temperature. After the addition was completed, the reaction was
stirred at 80 °C for 1.0 h, the heating was turned off and the temperature was naturally
cooled to 25 °C, and then 5.0 mL ammonia water was slowly added dropwise. 80 mL of
ethyl acetate and 80 mL of purified water were added to the reaction system
successively, and the liquids were extracted and separated. The organic phase was
1485 washed with saturated sodium bicarbonate solution and saturated sodium chloride
solution respectively, dried over anhydrous sodium sulfate, concentrated, and separated

Experimental example: anti-tumor activity test of the compounds
Test cells: 5 different types of human tumor cells were used in the experiment, including lung cancer cell A549, hepatocellular carcinoma cell HepG2, glioma Hs683, gastric cancer cell HGC27 and colon cancer cell HCT 116.
1500 The test method comprises the following steps:
1. Primary screening: tumor cells were treated with compounds at a concentration
of 10 pM for 48 h, and compounds with stronger anti-tumor activity were screened by
the survival rate of the tumor cells for ICo detection.
2. ICso detection
1505 1) Reagent preparation: the compound to be tested was dissolved to the
concentration of 10 mM with DMSO, and then was diluted in 10-fold gradient to 1 mM,
100 p M, 10 p M, 1Ip M, 0.1 p M. The concentration of stock solutions and working
solutions were shown in the following table:

solution working solution
10 mM 100 PM
1 mM 10 PM
100 PM 1 PM
10 PM 100 nM
1 PM 10 nM
0.1 PM 1 nM
2) Cell culture and plating: five kinds of tumor cells were cultured in DMEM
1510 medium containing 10% FBS. When the fusion degree reached 75-85%, the cells were
digested and counted and evenly spread into 96-well plates. The initial cell number is
shown in the following table:

3) Adding reagent: cells were plated for 24 h and dosed, DMSO solvent control
wells were set for each plate.
1515 4) MTT detection: after 48 h of dosing, MTT was added and after incubated for 4 h,
the supernatant was discarded, 100 p I1DMSO was added and shaked for 10 min for
detecting OD 5 7 0 and OD 72 0 values, wherein the cell viability is calculated as the
following formula:
Cell viability = (dosing groupOD57 0dosing group OD 720)/(DMSO group
1520 OD570-DMSOOD 72 0)
IC 50 of each compound was calculated by Graphpad software.
