- HQ_001 The effect of HQ_001 on the migration and differentiation of human lymphatic endothelial cells HLEC and the formation of tubular structures were studied by in vitro matrigel tube experiments.
- the results of light microscopy (Fig. 18) showed that the HLEC cells in the control group could migrate and differentiate on Matr igel within 6 hours, stretching and interconnecting to form a better network tubular structure.
- This structure is capillary-like and forms a multi-center node (Fig. 18a); whereas in the case of co-culture with 0.5 uM HQ_001, the formation of the tubular structure is significantly inhibited compared to the control group, resulting in the formation of HLEC cells.
- the mesh was significantly reduced, and the HLEC cell morphology gradually became rounded by the stretched long fusiform (Fig. 18b).
- HLEC cells grow normally adherently on the gelatin surface without migration and differentiation, nor form a tubular structure (Fig. 18c).
- Co-culture with 0.5 uM HQ_ 001 did not significantly affect normal adherence and growth of HLEC cells (Fig. 18d). It can be seen that HQ-001 can significantly inhibit the HLEC's ability to form tubes in a short period of time. This inhibition is not due to endothelial cell damage caused by its cytotoxic effects. Therefore, it was confirmed that HQ-001 has an effect of inhibiting lymphangiogenesis.
- HQ_001 inhibits the secretion of VEGFD from tumor cells
- VEGFD-LL/2 the expression of VEGFD in tumor cells was first detected by Western blot.
- the secretion of VEGFD in tumor cells is associated with the transcription factor AP-1, so the phosphorylation of the upstream kinase ERK1/2 of c_fos was tested.
- the PI3K/AKT pathway which regulates cell survival, migration, and proliferation, was also examined.
- the results of Western blot (Fig. 19) showed that the expression level of VEGFD was significantly increased in VEGFD-LL/2 cells compared with unloaded pcDNA-LL/2 cells. And after 12 h of action at 0.5 uM HQ_001, the VEGF-D expression level of VEGFD-LL/2 was significantly inhibited.

- BRK showed constitutive activation in tumor cells
- ERK of the control group showed significant phosphorylation of ⁇ , and the activation of this phosphorylation was blocked by HQ_001.
- phosphorylation of AKT was also significantly inhibited. Therefore, HQ-001 has a direct inhibitory effect on the signaling pathway of VEGFD-LL/2 cells.
- the inhibition of lymphangiogenesis and lymphatic metastasis by HQ_001 is associated with HQ-001 inhibiting the activation of ERK and AKT in tumor cells, thereby downregulating the expression of VEGFD.
- HQ-001 inhibits the expression of VEGFR3 in human lymphatic endothelial cells (HLBC)
- VEGFR3 in HLEC cells was detected by Western blot.
- the phospho-4-is and PI3K/AKT pathways of the kinase BRK1/2 were also examined.
- Western blot results (Fig. 20) showed that ERK1/2 phosphorylation and VEGFR3 expression levels were significantly inhibited in HLEC cells.
- the VEGFR3 pathway is the main pathway regulating lymphangiogenesis. Tumor-induced lymphangiogenesis plays a role in the activation of the VEGFR3 pathway by secreting VEGFD. Therefore, HQ-001 can inhibit lymphocyte generation by inhibiting BRK1/2 phosphorylation and VEGFR3 expression, thereby down-regulating cell division, migration, and tube formation.

- the zebrafish eggs were collected first, and the dead eggs and unhealthy fish eggs were picked and cultured in 28.5 °C fish water. Dilute HQ_001 to the desired concentration with fish water. After 6 hours, the eggs were distributed into a six-well plate and treated with HQ_001 solution. After incubation for 24 hours, anesthetize with 0.05% hydrated chloric acid, peel the eggs under a fluorescent microscope and observe angiogenesis.
- Fig. 21 The results are shown in Fig. 21.
- the internode tube is very complete and is in a beautiful trapezoidal arrangement.
- the concentration of HQ_001 is increased, it is 0.2 ⁇ , 0.4 ⁇ .
- the germination of the zebrafish internode tube was inhibited and the formation was incomplete.

Description
说 明 书 薰草菌素 A衍生物及其制备方法与应用 技术领域 Description: Kaempferol A derivative, preparation method and application thereof
本发明涉及药物化学领域, 尤其是薰草菌素 A衍生物及其制备方法与应 用。 Field of the Invention This invention relates to the field of medicinal chemistry, particularly to the xanthin A derivative, to its preparation and use.
背景技术 Background technique
薫草菌素 A ( Lavendustin A)是从链霉属的 gr i seolavendus菌的代谢 产物中分离得到的化合物, 对蛋白酪氨酸激酶具有较强的抑制活性。 而蛋白 酪氨酸激酶在控制肿瘤细胞增殖、 分化及死亡中扮演着重要角色, 近年来广 泛地被作为抗肿瘤药物的靶点, 小分子的蛋白酪氨酸激醇抑制剂已成为抗肿 瘤研究领域的重要课题之一。 薰草菌素 A作为蛋白酪氨酸激酶抑制剂的抑制 活性 Lavendustin A is a compound isolated from the metabolite of the genus gr i seolavendus of the genus Streptomyces and has a strong inhibitory activity against protein tyrosine kinase. Protein tyrosine kinase plays an important role in controlling tumor cell proliferation, differentiation and death. In recent years, it has been widely used as a target for anti-tumor drugs. Small molecule protein tyrosine alcohol inhibitors have become anti-tumor research. One of the important topics in the field. Inhibitory activity of spirulina A as a protein tyrosine kinase inhibitor
薰草菌素 A 薰草菌素 B Kaempferin A Kaempferol B
可见二者之间不同之处在于 A环上酚羟基氢的给体能力差异, 给体能力 越强, 活性越强。 It can be seen that the difference between the two is the difference in donor capacity of phenolic hydroxyl hydrogen on the A ring, and the stronger the donor ability, the stronger the activity.
薰草菌素 A被报道是与受体型蛋白酪氨酸激酶类型中表皮生长因子受体 ( EGFR )相互作用, 进而抑制 EGFR的自身磷酸化, 发挥抗肿瘤作用。 为了寻 找活性比 f草菌素 A更强的蛋白酪氨酸激酶抑制剂, 学者们已围绕薰草菌素 A作了一些修饰和衍生化工作, 主要是对其 A环结构以及 C环结构进行改造, 并获得部分活性较好的化合物, 所涉及到得专利包括 Di subs t i tuted lavendustin A analogs and pharmaceutical composition comprising the analogs (专利号为 US 6943191 Bl) ^ Pharmaceutical compositions of Lavendustin (专利号为 US 2008/0242686 Al) , 而到目前为止, 未见对薰草 菌素 A中 B环进行改造的相关报道。
恶性肿瘤细胞从原发部位直接侵入周围组织或者进入循环系统进行转 移。 肿瘤的转移是决定肿瘤患者存活的关键因素。 这种转移主要通过人体自 身的脉管系统: 血管 (血道转移)和淋巴管 (淋巴道转移) 来实现的。 肿瘤 细胞具有诱导血管和淋巴管新生的能力,这种能力是通过 VEGF家族成员来起 作用的。 VEGF家族包括 VEGF ( VEGFA )、 VEGFB, VEGFC、 VEGFD及胎盘生长因 子(P IGF )。 这些内皮细胞生长因子能够激活内皮细胞上的 VEGFR家族, 并且 启动与内皮细胞增殖、 迁移相关的细胞信号转导通路。 目前对于肿瘤血管新 生的研究已经有了极大的进展。 肿瘤在生长到一定大小的时候, 缺氧的环境 和对营养的需求刺激肺瘤细胞分泌血管生长因子 VEGF和 VEGFB, 从而诱导血 管往肿瘤方向发生, 为肿瘤提供氧气和营养, 同时也为肿瘤细胞的转移提供 重要的途径。 对于淋巴管新生的研究在近年来也取得很大的突破。 VEGFR3/FLT-4被发现与淋巴管的发生有关。 通过动物模型获得到的实验结果 发现, 肿瘤诱导的淋巴管新生是通过分泌 VEGFC或者 VEGFD , 特异性地结合 并激活 VEGFR3来实现的。 淋巴管新生与肿瘤淋巴转移息息相关。 Xanthophyllin A has been reported to interact with the epidermal growth factor receptor (EGFR) in the receptor-type protein tyrosine kinase type, thereby inhibiting autophosphorylation of EGFR and exerting an anti-tumor effect. In order to find protein tyrosine kinase inhibitors that are more active than f-organin A, scholars have done some modification and derivatization work on oxacin A, mainly for its A-ring structure and C-ring structure. Modifications and obtaining partially active compounds, including patents including Di subs ti tuted lavendustin A analogs and pharmaceutical composition including the analogs (Patent No. US 6943191 Bl) ^ Pharmaceutical compositions of Lavendustin (Patent No. US 2008/ 0242686 Al) , and so far, no reports have been made on the transformation of the B ring in the spirulina A. Malignant tumor cells directly invade surrounding tissues from the primary site or enter the circulatory system for metastasis. Tumor metastasis is a key factor in determining the survival of tumor patients. This transfer is mainly achieved by the body's own vasculature: blood vessels (hematopoiesis) and lymphatic vessels (lymphatic metastasis). Tumor cells have the ability to induce vascular and lymphangiogenesis, a function that is through the members of the VEGF family. The VEGF family includes VEGF (VEGFA), VEGFB, VEGFC, VEGFD, and placental growth factor (P IGF ). These endothelial cell growth factors activate the VEGFR family on endothelial cells and initiate cellular signaling pathways involved in endothelial cell proliferation and migration. At present, great progress has been made in the study of tumor angiogenesis. When the tumor grows to a certain size, the hypoxic environment and the need for nutrition stimulate the tumor cells to secrete vascular growth factors VEGF and VEGFB, thereby inducing blood vessels to the tumor, providing oxygen and nutrients to the tumor, and also tumor cells. The transfer provides an important avenue. Research on lymphangiogenesis has also made great breakthroughs in recent years. VEGFR3/FLT-4 was found to be involved in lymphangiogenesis. The experimental results obtained by animal models found that tumor-induced lymphangiogenesis is achieved by secreting VEGFC or VEGFD, specifically binding and activating VEGFR3. Lymphangiogenesis is closely related to tumor lymphatic metastasis.

HQ_001与 VEGFR3间的相互作用模式 Interaction mode between HQ_001 and VEGFR3
采用计算机药物虚拟筛选技术和细胞水平技术获得 HQ_001 HQ_002, HQ_003, HQ_005和 HQ_010抗肿瘤效果皆比母体薰草菌素 A更佳, 于是 选择活性相对最优的 HQ_001作为以下研究的新型化合物。 图 15显示了 HQ— 001与 VEGFR3间的相互作用模式。 从图 15 (b)中观察到, HQ_001的邻羟 基苯甲酸部分的羧基氧和羟基氧, 与 CyslOO的 alpha-氨基氬形成氢键; HQ-001的对二羟基苯酚部分其中一个羟基氧,为 Lys49的 alpha-氨基氢提供 氢键受体(acceptor) , 而该羟基上的氢, 为 Ala47的羰基氧, 提供氢键给体 (donor) Using the computer drug virtual screening technology and cell level technology to obtain HQ_001 HQ_002, HQ_003, HQ_005 and HQ_010 are better than the parental oxacillin A, so the HQ_001 with relatively optimal activity was selected as the new compound for the following study. Figure 15 shows the interaction pattern between HQ-001 and VEGFR3. It is observed from Fig. 15 (b) that the carboxyl oxygen and hydroxyl oxygen of the o-hydroxybenzoic acid moiety of HQ_001 form a hydrogen bond with the alpha-amino argon of CyslOO; one of the hydroxyl groups of the p-dihydroxyphenol of HQ-001 is The alpha-amino hydrogen of Lys49 provides a hydrogen bond acceptor, and the hydrogen on the hydroxyl group, which is the carbonyl oxygen of Ala47, provides a hydrogen bond donor.

HQ _ 001诱导人淋巴内皮细胞( HLEC ) 凋亡的时间依赖性 HQ _ 001 induces time-dependent apoptosis of human lymphatic endothelial cells (HLEC)
为了探索 HQ_001诱导 HLEC细胞凋亡在时间上的规律, 实验中还对 HQ-001作用下的 HLEC细胞核形态进行了动态观察(图 17 )。 在 HQ-001分别
作用 Oh, 2h, 4h, 8h, 12h和 24h之后, 对细胞进行 Hoechst33258染色。在 荧光显 镜下观察发现, HQ_001作用 8h后, HLEC细胞开始产生凋亡的迹象, 这种迹象随着时间的延长逐渐增多。 在作用 24h之后, 能明显看到大量的细 胞产生核固缩、 染色体凝集等现象, 并能观察到凋亡小体的存在。 In order to explore the temporal regularity of HQ_001-induced apoptosis of HLEC cells, the morphological morphology of HLEC cells under HQ-001 was also observed dynamically (Fig. 17). In HQ-001 respectively After Oh, 2h, 4h, 8h, 12h and 24h, the cells were stained with Hoechst 33258. Under the fluorescence microscope, it was found that HLEC cells began to produce signs of apoptosis after 8 hours of HQ_001 treatment, and this sign gradually increased with time. After 24 hours of action, it was obvious that a large number of cells produced nuclear pyknosis, chromosome agglutination, etc., and the presence of apoptotic bodies was observed.

HQ— 001抑制人淋巴内皮细胞(HLEC) 的成管能力 HQ-001 inhibits the ability of human lymphatic endothelial cells (HLEC) to establish tube
通过体外 matrigel成管实验, 研究了 HQ_001对人淋巴管内皮细胞 HLEC迁移分化并形成管状结构的影响。 光镜下观察结果(图 18 )显示, 对照 组 HLEC细胞在 6小时内能够在 Matr igel上迁移分化, 伸展并相互连接, 形 成较好的网络管状结构。 这种结构呈毛细血管状, 并形成多中心的结点(图 18 a); 而与 0.5uM HQ_001共培养的情况下, 与对照组相比, 管状结构的形 成明显受到抑制, 使 HLEC细胞形成的网格明显减少, HLEC细胞形态由拉伸 的长梭形逐渐变圓 (图 18 b)。 The effect of HQ_001 on the migration and differentiation of human lymphatic endothelial cells HLEC and the formation of tubular structures were studied by in vitro matrigel tube experiments. The results of light microscopy (Fig. 18) showed that the HLEC cells in the control group could migrate and differentiate on Matr igel within 6 hours, stretching and interconnecting to form a better network tubular structure. This structure is capillary-like and forms a multi-center node (Fig. 18a); whereas in the case of co-culture with 0.5 uM HQ_001, the formation of the tubular structure is significantly inhibited compared to the control group, resulting in the formation of HLEC cells. The mesh was significantly reduced, and the HLEC cell morphology gradually became rounded by the stretched long fusiform (Fig. 18b).
为了验证 matrigel組分的诱导作用和排除药物毒性的影响,实验中设置 了在明胶表面的对照实验。在没有药物作用和没有 matrigel的情况下, HLEC 细胞在明胶表面正常贴壁生长, 不发生迁移和分化, 也不形成管状结构(图 18 c )。 与 0.5uM HQ_ 001共培养并没有明显影响 HLEC细胞的正常贴壁和生长 (图 18 d)。由此可见, HQ— 001能够在较短时间内明显抑制 HLEC的成管能力。 这种抑制作用并不是由于其细胞毒作用导致的内皮细胞损伤。 因此证明, HQ-001具有抑制淋巴管生成的作用。 In order to verify the induction of the matrigel component and to rule out the effects of drug toxicity, a control experiment on the gelatin surface was set up in the experiment. In the absence of drug action and without matrigel, HLEC cells grow normally adherently on the gelatin surface without migration and differentiation, nor form a tubular structure (Fig. 18c). Co-culture with 0.5 uM HQ_ 001 did not significantly affect normal adherence and growth of HLEC cells (Fig. 18d). It can be seen that HQ-001 can significantly inhibit the HLEC's ability to form tubes in a short period of time. This inhibition is not due to endothelial cell damage caused by its cytotoxic effects. Therefore, it was confirmed that HQ-001 has an effect of inhibiting lymphangiogenesis.

HQ_001抑制肿瘤细胞 VEGFD的分泌 HQ_001 inhibits the secretion of VEGFD from tumor cells
本实验通过 Western blot方法首先检测了肿瘤细胞中 VEGFD的表达。肿 瘤细胞中 VEGFD的分泌与转录因子 AP-1有关,因此实验对 c_fos的上游激酶 ERK1/2的磷酸化进行了检测。 同时, 也对调控细胞存活、 迁移、 增殖的 PI3K/AKT通路进行了检测。 Western blot实验结果(图 19)显示, VEGFD- LL/2 细胞较空载的 pcDNA- LL/2细胞, VEGFD的表达水平显著增高。 并且在 0.5uM HQ_001作用 12h后, VEGFD-LL/2的 VEGF-D表达水平受到明显的抑制。 这种 抑制作用与 HQ_001阻断了肿瘤细包中 MEK/ERK1/2通路有关。 从结果可以看 到, 肿瘤细胞中 BRK呈现组成性激活, 对照组的细胞中 ERK发生了明显的磷 δ交化, 这种磷酸化的激活被 HQ_001阻断。 同样, AKT的磷酸化也受到了明显 的抑制。
因此, HQ-001对于 VEGFD-LL/2细胞的信号通路有直接的抑制作用。 HQ_001抑制淋巴管新生和淋巴转移的结果与 HQ-001抑制肿瘤细胞中 ERK和 AKT的活化, 从而下调 VEGFD的表达有关。 In this experiment, the expression of VEGFD in tumor cells was first detected by Western blot. The secretion of VEGFD in tumor cells is associated with the transcription factor AP-1, so the phosphorylation of the upstream kinase ERK1/2 of c_fos was tested. At the same time, the PI3K/AKT pathway, which regulates cell survival, migration, and proliferation, was also examined. The results of Western blot (Fig. 19) showed that the expression level of VEGFD was significantly increased in VEGFD-LL/2 cells compared with unloaded pcDNA-LL/2 cells. And after 12 h of action at 0.5 uM HQ_001, the VEGF-D expression level of VEGFD-LL/2 was significantly inhibited. This inhibition is related to HQ_001 blocking the MEK/ERK1/2 pathway in tumor fines. As can be seen from the results, BRK showed constitutive activation in tumor cells, and ERK of the control group showed significant phosphorylation of δ, and the activation of this phosphorylation was blocked by HQ_001. Similarly, phosphorylation of AKT was also significantly inhibited. Therefore, HQ-001 has a direct inhibitory effect on the signaling pathway of VEGFD-LL/2 cells. The inhibition of lymphangiogenesis and lymphatic metastasis by HQ_001 is associated with HQ-001 inhibiting the activation of ERK and AKT in tumor cells, thereby downregulating the expression of VEGFD.

HQ— 001抑制人淋巴内皮细胞 ( HLBC ) VEGFR3的表达 HQ-001 inhibits the expression of VEGFR3 in human lymphatic endothelial cells (HLBC)
本实验通过 Western blot方法检测了 HLEC细胞中 VEGFR3的表达。 同时 也对激酶 BRK1/2的磷酸 4匕和 PI3K/AKT通路进行了检测。 Western blot 实验 结果(图 20 )显示, 在 HLEC细胞中 ERK1/2的磷酸化和 VEGFR3表达水平受 到了明显抑制。 VEGFR3通路是调控淋巴管新生的主要途径, 肿瘤诱导的淋巴 管生成作用就是通过分泌 VEGFD来激活 VEGFR3通路起作用的。 故 HQ-001可 通过抑制 BRK1/2磷酸化、 VEGFR3表达, 从而下调细胞分裂、 迁移、 成管, 进而达到抑制淋巴管生成的作用。 In this experiment, the expression of VEGFR3 in HLEC cells was detected by Western blot. The phospho-4-is and PI3K/AKT pathways of the kinase BRK1/2 were also examined. Western blot results (Fig. 20) showed that ERK1/2 phosphorylation and VEGFR3 expression levels were significantly inhibited in HLEC cells. The VEGFR3 pathway is the main pathway regulating lymphangiogenesis. Tumor-induced lymphangiogenesis plays a role in the activation of the VEGFR3 pathway by secreting VEGFD. Therefore, HQ-001 can inhibit lymphocyte generation by inhibiting BRK1/2 phosphorylation and VEGFR3 expression, thereby down-regulating cell division, migration, and tube formation.

HQ_001抑制斑马鱼节间血管的生成 HQ_001 inhibits angiogenesis in zebrafish
肿瘤的生长、 侵袭和转移的过程都依赖新生血管的生成, 而斑马鱼模型 由于能清晰地观察到血管的发生发展, 已成为一种新型体内模式生物学, 非 常适合体内血管生物学的研究。 本实验采取先收集斑马鱼鱼卵, 挑除死卵和 不健康的鱼卵, 置 28.5°C鱼水中培养。 用鱼水稀释 HQ_001到所需浓度, 6 小时后,将鱼卵分配到六孔板中,加入 HQ_001溶液处理。孵育 24h后,用 0.05% 水合氯酸麻醉, 荧光显微镜下剥卵并观察血管新生情况。 Tumor growth, invasion and metastasis depend on the formation of new blood vessels. The zebrafish model has become a new type of in vivo model biology because it can clearly observe the development of blood vessels, which is very suitable for the study of vascular biology in vivo. In this experiment, the zebrafish eggs were collected first, and the dead eggs and unhealthy fish eggs were picked and cultured in 28.5 °C fish water. Dilute HQ_001 to the desired concentration with fish water. After 6 hours, the eggs were distributed into a six-well plate and treated with HQ_001 solution. After incubation for 24 hours, anesthetize with 0.05% hydrated chloric acid, peel the eggs under a fluorescent microscope and observe angiogenesis.
结果见图 21, 在 Control组中, 节间管非常完整, 成漂亮的梯形排布, 0.1 μΜ HQ_001处理时, 药效作用并不明显, 但当 HQ_001作用浓度提高后,在 0.2 μΜ、 0.4 μΜ时, 斑马鱼节间管的萌芽被抑制, 形成并不完整。 相同浓度 ( 0.4 μΜ)的 HQ_001与薰草菌素 Α处理后, HQ_001体现了更强地抑制斑马鱼节 间管形成的作用。 这说明 HQ_001能很强抑制新血管的形成。 The results are shown in Fig. 21. In the Control group, the internode tube is very complete and is in a beautiful trapezoidal arrangement. When 0.1 μΜ HQ_001 is treated, the pharmacodynamic effect is not obvious, but when the concentration of HQ_001 is increased, it is 0.2 μΜ, 0.4 μΜ. At the time, the germination of the zebrafish internode tube was inhibited and the formation was incomplete. HQ_001 treated with the same concentration (0.4 μΜ) of HQ_001 and sphingosine 体现 showed a stronger inhibition of zebrafish internode formation. This shows that HQ_001 can strongly inhibit the formation of new blood vessels.
