BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to development of cancer drug, especially relates to the development of novel 1,2-disubstituted amido-anthraquinone derivatives, preparation method and application thereof.
2. Description of the Prior Art
Telomere
A telomere is a region of repetitive DNA at the end of a chromosome, which protects the end of the chromosome from deterioration, recombination, and end-to-end fusion. Telomere is composed of short and repeated DNA sequences. A high percentage of guanine (G) is present in this DNA sequence from 5′-end to 3′-end. The telomere DNA sequence (TTAGGG)n is conserved among vertebrates, including human.
In normal somatic cell, the terminal end of the chromosome will lose a part of RNA primer after each replication, and will shorten off about 50-60 bp after each cell division. When the telomere is shortened to a certain extent, cell will go to apoptosis, this phenomenon is called an end-replication problem of a cell.
Telomerase
Telomerase is the enzyme that synthesizes telomeric DNA, the terminal DNA at chromosome ends which, together with telomere-binding proteins, confers stability to chromosomes. In most of organism, the replication and maintenance of the length of telomere has to rely on telomerase. The telomerase is composed of RNA and protein subunits. At present, part of important telomerase subunits had been identified. The composition of human telomerase comprising: human telomerase reverse transcriptase (hTERT) having reverse transciptase activity, human telomerase RNA component used as a template, and some telomere-binding proteins such as human telomerase-associated protein, p23, hsp90, hsp40, hsp70 and the like.
Many research studies had indicated that the activity of human telomerase can only be detected in cells having high proliferation ability, for example, germ cells, hemopoietic cells, part of stem cells, most of immortalized cells and most of tumor cells. In the somatic cell, the telomere will be shorten gradually as the number of cell division increased, which may be considered as the mitotic clock for counting the number of cell division. When a telomere is shortened to a certain extent, cell will stop division and entering aging stage, stay at this stage for a period of time, and then goes to death. This period of time is called mortality stage 1 (M1 stage). When a tumor suppressor gene such as p53 or Rb is mutated within M1 stage, the cell might escape from aging stage and keeps on cell division in this period of time which is called mortality stage 2 (M2 stage). If a cell lacks of telomerase activity during this period, the length of a telomere will be reduced still, the telomere will not be able to protect the terminal end of the chromosome, and this might result into the instability of the chromosome, as well as the cell can not transfer genetic information completely and enters apoptosis in the end. Therefore, M2 stage is also called a crisis stage. Most of cells will die in M2 stage, except small part of cells with telomerase activity will be survived. This small part of cells will continue to divide without limitation and become an immortalized cell (or a cancer cell).
In view of the foregoing, it is thought generally that the activation of telomerase can maintain the length of a telomere so as to prevent a cell from entering the ageing stage; or the inhibition of telomerase activity can be used to limit the division of a cancer cell. Both thought may become the key factors in the development of a cell toward immortalization or cancerization. In summary, using the telomerase inhibitors to treat the cancer have been considered as a novel cancer-specific therapy, as most tumor cells have high expression of telomerase, whereas most normal somatic cells express low or undetectable levels of telomerase and is therefore an attractive target for the design of anticancer agents.
Anthraquinone-containing extracts from different plant sources such as senna, cascara, aloe, frangula, and rhubarb have been found to have wide variety of pharmacological activities such as anti-inflammatory, wound healing, analgesic, antipyretic, antimicrobial, and antitumor activities. And some of the anthraquinone derivatives had also shown the antitumor activity. Therefore, many investigators consider them as highly promising lead candidates in drug design.
In view of the importance of the development of cancer therapy drugs, the invention provides the inventive 1,2-disubstituted amido-anthraquinone derivatives, preparation method and application thereof.

Example 3
Telomerase Activity Assays
Compounds CC-01 to CC-50 (total 50 compounds) chemically synthesized above were subjected to following three sections of telomerase activity assays: 3-1. Telomere repeat amplification protocol (TRAP) assays; 3-2. Secreted alkaline phosphatase assay (SEAP assay) and MTT assay, to assay the cell survival rate of cancer cell; 3-3. The United State National Cancer Institute (NCI) had selected 5 compounds from the invention, which were subjected to cell toxicity assay against 55 to 60 kinds of cancer cell lines.
3-1. Telomere Repeat Amplification Protocol (TRAP) Assay:
Telomerase activity was detected by a modified version of the general TRAP protocol. Telomerase products were resolved by 10% polyacrylamide gel electrophoresis and visualized by staining with SYBER Green. As a source of telomerase, the total cell lysates derived from lung cancer cell line H1299 cells were used. Protein concentration of the lysates was assayed using Bio-Rad protein assay kit using BSA standards.
3-2. SEAP Assay and MTT Assay
3-2-1. SEAP Assay
Cell Culture and Assessment of hTERT:
H1299 is a non-small-cell lung cancer cell strain and possesses telomerase activity, therefore, is suitable to be used as a model cell strain for screen telomerase inhibitor. H1299 were grown in RPMI 1640 media supplemented with 10% fetal bovine serum, 100 units/mL penicillin and 100 mg/mL streptomycin in a humidified atmosphere with 5% CO2 at 37° C. Culture media were changed every three days. To establish stable cell lines that the expression of hTERT could be monitored by a reporter system, a about 3.3 kbp DNA fragment ranging from −3338 to +1 bp of the hTERT gene (hTERT promoter, PhTERT) was subcloned upstream to a secreted alkaline phosphatase gene (SEAP) and transfected into H1299 by electroporation. The stable clones were selected using G418. The stable clones derived from H1299 were cultured using conditions that are similar to their parental cells.
SEAP Assay:
Secreted alkaline phosphatase was used as the reporter system to monitor the transcriptional activity of hTERT. Here, about 104 cells each were grown in 96-well plates and incubated at 37° C. for 24 hours and changed with fresh media. Varying amounts of drugs were added and cells were incubated for another 24 hours. Culture media were collected and heated at 65° C. for 10 min to inactivate heat-labile phosphatases. An equal amount of SEAP buffer (2 M diethanolamine, 1 mM MgCl2, and 20 mM L-homoarginine) was added to the media and p-nitrophenyl phosphate was added to a final concentration of 12 mM. Absorptions at 405 nm were taken, and the rate of absorption increase is determined (the increasing rate of absorbance at 405 nm was used to represent the activity of SEAP).
Further, cells were subjected to MTT assay to compare the relative toxicity or effect of each compound on cell proliferation and activity.
3-2-2. MTT Assay
MTT assay is a method often used to determine cell survival rate or proliferation, which is described briefly as followed:
The above-described cells are cultured in a 96-well plate, to which was added with 25 μl MTT solution, and cultured in a 37° C. carbon dioxide incubator for 4 hours. Then, 100 μl Lysis buffer is added and incubated in a 37° C. carbon dioxide incubator overnight. An ELISA reader (Bio-Rad Model 450) is used to read optical density (O.D.) at 550 nm.
3-3. The National Cancer Institute (NCI)'s Anticancer Drug Screen
In brief, cellular protein levels were determined after 48 hours of drug exposure by sulforhodamine B colorimetry. Through the use of a time 0 cell control, the cell growth can be determined for each cell line thus allowing calculations of the 50% growth inhibitory concentration (GI50), the total growth inhibition (TGI), and the 50% lethal concentration (LC50). Comparison to plates not exposed to drug permits determination of concentration and times of exposure conferring 50% net growth inhibition (GI50), TGI, and 50% cell kill (LC50). These data are then plotted as mean bar graphs and as dose-response curves.
From the data analysis it follows that approximately 95% of the actives (potent anticancer drugs) from the 60 cell line screen can be identified. By these criteria, five compounds (each with its certification number, refer to FIG. 4) of the invention were reported that having anticancer activity.
Synthesis and Analysis of Each Compound:
The chemical synthetic procedure of 1,2-disubstituted amidoanthraquinone derivatives described in Example 2 was disclosed further in following examples.
Testing Instruments:
Melting point determination was carried out on a Büchi 545 melting point tester. IR (Kbr) was recorded on a Perkin-Elmer 983G spectrometer. MS was determined in National Chiao Tung University Instrument Center. 1H-NMR and 13C-NMR were recoded on Varian GEMINI-300 (300 MHz) or BRUKER AV 500 MHz.

Example 54
Screening Telomerase Inhibitor by Telomere Repeat Amplification Protocol (TRAP) Assay
In the FIG. 5A to 5C, a positive control group (P) was water that had been sterilized; while a negative control group (N) was 5 μl of 0.1 mg/ml RNase A (CLONTECH). It could be seen that a number of telomeric fragments were presented in the positive control group (P), while no fragments was presented in the negative control group (N). 10 μM was selected as the concentration used to screen compounds. All compounds were allowed to go through a preliminary screening. Then, more effective compounds among them were screened at different concentration. The results were shown in FIG. 5A to 5C. All of compounds CC-01 to CC-50 did not exhibit significant inhibition effect against telomerase. Therefore, it was suggested that, either symmetrically di-substituted or asymmetrically di-substituted 1,2-disubstituted amido anthraquinone derivatives exhibited poor inhibiting effect for the telomerase.
Example 55
Results of Secreted Alkaline Phosphatase Assay (SEAP Assay) and MTT Assay
Results of SEAP and MTT analysis were shown in Table 1 to 5. It indicated that compounds having symmetric (CC-01 to CC-03) or asymmetric (CC-06 to CC-08) side-chain structures exhibited better cell toxicity than 1, 2-diaminoanthraquinone at concentration of 1 μM, 10 μM, and 100 μM. Further, compounds CC-01 and CC-06 exhibited higher cell toxicity activity than mitoxantrone and doxorubicin. Most of compounds CC-09 to CC-22 exhibited very strong cell toxicity activity at high concentrations (100 μM, 10 μM). In addition, it could be found that two compounds CC-14 and CC-15 possessed very strong cell toxicity activity even at low concentration (1 μM), with a inhibitory activity even better than mitoxantrone and doxorubicin. Furthermore, among compounds CC-23 to CC-32, it could be found that the cancer cell inhibitory activity of compound CC-28 was similar with mitoxantrone and doxorubicin, even better. Compounds CC-33 to CC-50 exhibited lower cell toxicity activity at high concentrations (100 μM, 10 μM), with a significant lower cell toxicity at 10 μM. Only compounds CC-43 and CC-44 possessed higher inhibitory activity among compounds CC-35 to CC-50.
In summary, the results of SEAP and MTT assays indicated that at low concentration (1 μM), compounds CC-01, CC-06, CC-14, CC-15 and CC-28 exhibited very strong cell toxicity activity (cell survival rate lower than 50%), namely, said compounds possessed cell toxicity activity against non-small-cell lung cancer cell strain H1299, with an effect even better than mitoxantrone and doxorubicin. Compound CC-33 exhibited no significant cell toxicity both at low and high concentrations (1 μM, 10 μM, and 100 μM). Other compounds possessed cell toxic activity at high concentration (100 μM, 10 μM).

Example 56
The Cytotoxicity Result of National Cancer Institute's Anticancer Drug Screen
The screening system in United State National Cancer Institute (NCI) is consisted of 60 kinds of different human cancer cells, which can be used to assay the growth-inhibiting ability or cell toxicity of a compound against various cancer and tumor at a certain concentration.
Compounds CC-04, CC-12, CC-23, CC-38, and CC-43 were listed as test compounds (Table 6) in the NCI's screen. Results were shown in Table 7. Among these compounds, compound CC-12 exhibited growth-inhibiting effect against cancer cells such as leukemia, non-small cell lung cancer, colon cancer, central nervous system (CNS) cancer, melanoma, ovarian cancer, renal cancer, prostate cancer, breast cancer and the like. Compound CC-23 could inhibit the cancer cell growth of leukemia and melanoma. Compound CC-43 could inhibit the cancer cell growth of leukemia, melanoma, and ovarian cancer. In addition, in the assay against human multiple drug-resistant breast cancer cell NCI/ADR-RES (derived from ovarian cancer), compounds CC-12, CC-23 and CC-43 possessed drug-resistance against adriamycin (ADR). Under comparison the result of compounds CC-12 and CC-43 with mitoxantrone and doxorubicin in NCI database, it could be even found that the 50%-growth-inhibitory ability or 50% net growth inhibition (GI50) of compound CC-43 (0.13 μM) was equivalent to that of doxorubicin (0.11 μM) (FIG. 6).
