Definitions
- the invention relates to the synthesis of tetrahydroquinoline derivatives and their use in the treatment of various carcinomas.
- Chemotherapeutic approaches are most effective to fight cancers with large growth factors, i.e., ones whose cells are rapidly dividing. Ideally cytotoxic agents that have specificity to recognize certain cancer and tumor cells while not affecting normal cells or other less malign tumor cells would be extremely desirable. Unfortunately, none have been found and instead agents that target especially rapidly dividing cells (both tumor and normal) have been generally used.
- Tetrahydroquinoline moiety is present in various natural products and many tetrahydroquinoline derivatives bearing simple or complex substituents exhibit a broad range of biological activities [1] Therefore, it has been attracted researchers continuously to develop methods for the synthesis of tetrahydroquinoline derivatives. [2] Among the various methods, Lewis acid catalyzed aza-Diels-Alder reaction of N-arylimines with various dienophiles is one of the most powerful tools for constructing 2,3,4-substituted tetrahydroquinoline derivatives.
- the present invention relates to tetrahydroquinoline derivatives and their use for the treatment of cancer or a viral infection in warm blooded animals, particularly in humans and other mammals.
- the methods may use such a compound in combination with a potentiator or a chemotherapeutic agent.
- the present invention also relates to methods for preparation of such compounds.

Description
- This application is based on and claims priority of our U.S. provisional application Ser. No. 60/324,392, filed 24 Sep. 2001, incorporated herein by reference in full.
- This invention was made with partial government support under grant numbers CHE-9733256 from the National Science Foundation. The U.S. government has certain rights in this invention.
- Not applicable
- 1. Field of the Invention
- The invention relates to the synthesis of tetrahydroquinoline derivatives and their use in the treatment of various carcinomas.
- 2. General Background of the Invention
- U.S. Pat. No. 6,077,862, incorporated herein by reference, provides an excellent background for the cancer chemotherapeutic use of the this invention.
- Chemotherapeutic approaches are most effective to fight cancers with large growth factors, i.e., ones whose cells are rapidly dividing. Ideally cytotoxic agents that have specificity to recognize certain cancer and tumor cells while not affecting normal cells or other less malign tumor cells would be extremely desirable. Unfortunately, none have been found and instead agents that target especially rapidly dividing cells (both tumor and normal) have been generally used.
- Clearly, the development of agents that would target certain cancer cells due to some unique specificity for them would be a breakthrough.
- Tetrahydroquinoline moiety is present in various natural products and many tetrahydroquinoline derivatives bearing simple or complex substituents exhibit a broad range of biological activities[1] Therefore, it has been attracted researchers continuously to develop methods for the synthesis of tetrahydroquinoline derivatives.[2] Among the various methods, Lewis acid catalyzed aza-Diels-Alder reaction of N-arylimines with various dienophiles is one of the most powerful tools for constructing 2,3,4-substituted tetrahydroquinoline derivatives.[3] When cyclic enol ethers, such as 2,3-dihydrofuran or 3,4-dihydro-2H-pyran, are employed as dienophiles, tricyclic compounds (furano or pyrano quinoline derivatives) are obtained.[4] A one-pot procedure for synthesizing such compounds, based on the three components reaction of a substituted aniline, an aryl aldehyde and an electron-rich olefin in the presence of Lewis acid catalysts, has been reported recently.[5] Since this reaction is much efficient with aryl-aldimines than with alkyl-aldimines, various 2-aryl-tetrahydroquinolines have been synthesized and only a few examples of 2-substituted tetrahydroquinoline derivatives were reported. No procedure was available to synthesize 2-substituted tetrahydroquinoline derivatives via a simple and direct coupling between an aniline derivative and a cyclic enol ether or a cyclic hemiacetal (or its equivalent).
- Due to the above-mentioned problems in the art, the present inventors have sought improvements and provide such improvements herein.
- The present invention relates to tetrahydroquinoline derivatives and their use for the treatment of cancer or a viral infection in warm blooded animals, particularly in humans and other mammals. The methods may use such a compound in combination with a potentiator or a chemotherapeutic agent. The present invention also relates to methods for preparation of such compounds.

- Methods for synthesizing these compounds of the present invention involve the combining certain aniline derivatives include aniline with a cyclic enol ethers, or cyclic hemiacetals or their chemical equivalents. The process is also suitable for the rapid generation of combinatorial libraries of tetrahydroquinoline derivatives.
- The synthetic procedure is quite simple and works in a variety of solvents including but not limited to water, ethanol, dichloromethane, or without solvent. Polymer and solid supported synthesis of tetrahydroquinoline derivatives are also possible by this method. Stereoselective formation of the compounds is also possible when certain chiral components are used in the reaction. Due to its simplicity and the fact that hazardous chemicals and special precautions are not required, this invention is suitable for the practical and convenient synthesis of many related analogs including stereochemically pure derivatives. In this manner, this invention is useful for the preparation of various pharmaceuticals and agrochemicals.
- One aspect of the invention is a process of generating tetrahydroquinoline derivatives by reacting aniline derivatives with cyclic enol ethers or cyclic hemiacetals and they chemical equivalents under mild conditions.

- K. Studies
- The following studies were performed to test the effectiveness of the tetrahydroquinoline derivatives of the present invention against certain cancers and viral infections.
- Colon and Melanoma Tumor Cells Test:
- The following cell culture tests were performed by the National Cancer Institute of the National Institute of Health. The compounds listed below have been evaluated in the 3-cell line, one dose primary anticancer assay. The compounds which pass our criteria for activity in this assay will be scheduled automatically for evaluation against the full panel of 60 tumor cell lines. For the past 10 years, the Development Therapeutic Program (DTP), Division of Cancer Treatment and Diagnosis (DCTD), National Cancer Institute (NCI) has used an in vitro model consisting of 60 human tumor cell lines as the primary anticancer screen [Ref: J. Natl, Cancer Inst., 83:757-766, 1991]. An analysis of the data indicated that approximately
- 95% of the actives from the 60 cell line screen can be identified using only three cell lines. For this reason, the DTP has now begun using, as its primary anticancer assay, a 3-cell line panel consisting of the MCF7 (Breast), NCI-H460 (Lung), and SF-268 (CNS). This 3-cell line, one-dose assay has been in use by DTP for several years for the evaluation of combinatorial libraries and has proven to be an effective pre-screen. The inclusion of this assay in our decision-making process will allow for more detailed evaluation of agents which have exhibited some level of ability to inhibit the growth of human tumor cells in culture.
- In the current protocol, each cell line is inoculated and preincubated on a microtiter plate. Test agents are then added at a single concentration and the culture incubated for 48 hours. End-point determinations are made with alamar blue (Biotechniques 21(5) 780-782 (1996)). Results for each test agent are reported as the percent of growth of the treated cells when compared to the untreated control cells. Compounds which reduce the growth of any one of the cell lines to approximately 32% or less (negative numbers indicate cell kill) are passed on for evaluation in the full panel of 60 cell lines over a 5-log dose range. The testing results of selected compounds are listed in Table 2.

No. Concentr.(units) MCF7 NCI-H460 SF-268 3-1 1.000E−04 (Molar) −1 −1 −1 3-2 1.000E−04 (Molar) 0 57 22 3-3 1.000E−04 (Molar) 7 100 77 4-1 1.000E−04 (Molar) 0 0 0 5-1 1.000E−04 (Molar) 0 29 2 - Further 60 cell-line tests showed that cpd. No. 3-1 is highly potent and selectively killed cancer cells of EKVX (non-small cell lung cancer), SF-539 (CNS cancer), PC-3 and DU-145 (prostate cancer), MDA-MB-435 (breast cancer), and Delta cancer cell lines even at 1.000E-08 molar concentration; whereas showed very week effect against other cell lines. On the other hand, cpd. No. 5-1 is highly selective for PC-3 (prostate cancer) and Delta cancer, and moderately selective for CCRF-CEM (and other leukemia cancer cells), as well as NCI-H522 (non-small cell lung cancer), HCT (colon cancer), and CAKI-1 (renal cancer). The high selectivity for certain cancer cells observed with these compounds provides the possibility of killing cancer cells in the presence of other cells. It also provides the possibility of connecting more effective cancer-drugs such as Taxol to these compounds for more effective cancer chemotherapy.
- It should also be noted that several of compounds synthesized showed moderate biological activities for anti-viral studies.
- Methods for Synthesizing Compounds of Formula A #STR 1#
- Advantages and Improvements Over Existing Technology:
- Although there are many known methods for the synthesis of tetrahydroquinoline derivatives due to the vital importance of these compounds, any conceptually new and practical method in this area is of special significance. The existing methods for synthesizing tetrahydroquinoline derivatives use highly reactive reagents such as titanium tetrachloride, which generally require anhydrous solvents (such as methylene chloride, a carcinogen) and inert gas atmosphere, and protection of protonic functional groups such as hydroxyl and amines. Thus, the existing methods have high cost, are environmentally unsafe and potentially hazardous. Due to shortcomings of the existing methods, no general and practical synthesis of compounds with Formula A is available. The present invention offers a number of advantages over existing methods for synthesizing tetrahydroquinoline derivatives, including:
- 1. This new method for tetrahydroquinoline synthesis allows to synthesize tetrahydroquinoline derivatives having the general Formula A that some has not been accessible via the existing methods.
- 2. This new method for tetrahydroquinoline synthesis is exceptionally environmentally friendly and practical. The reactions can be done in water or aqueous solvents at ambient temperature without using any toxic, hazardous or corrosive materials, such as strong acids, strong bases, organotin, or other highly corrosive reagents such as titanium tetrachloride. Also the reaction does not require an inert atmosphere, and can be done in the air. Furthermore, the reaction can be done without using additional solvent other than the reactants. For compounds with protonic functional groups such as hydroxyl, protection is not required, which shortens synthetic steps and saves the cost.
- 3. The method of the invention offers direct construction of these complicated of Formula A from simple aniline derivatives and cyclic enol ethers or cyclic hemiacetals or their chemical equivalents.
- 4. The present method is highly versatile, allowing a high degree of structural variation in all reacting components. Since the reaction involves an initial condensation between aniline derivatives with one equivalent of cyclic enol ethers or cyclic hemiacetals or their chemical equivalents, followed the reaction of the intermediate with another equivalent of enol ethers or cyclic hemiacetals or their chemical equivalents, the method allows the one-pot construction of tetrahydroquinoline derivatives from several readily available building blocks. For these reasons, this method is easily applicable to the solid or liquid phase combinatorial synthesis of tetrahydroquinoline derivatives.
- 5. Because two-carbon based stereogenic centers were formed during the reaction process, the method allows the synthesis of compounds with formula A with stereochemical control if a chiral component is present.
- 6. Because the reaction can be carried out in water, water soluble reagents can be used and water soluble tetrahydroquinoline derivatives can be generated, which are highly important for drug formulation and drug delivery.
- The following examples are put forth so as to provide those of ordinary skill in the art with a complete disclosure and description of how to perform the processes of the present invention, and are not intended to limit the scope of what the inventors regards as their invention. Efforts have been made to ensure accuracy with respect to numbers used (e.g. amounts, temperature, etc.) but some experimental errors and deviations should be accounted for. Unless indicated otherwise, molecular weight is weight average molecular weight, temperature is in degrees centigrade, and pressure is at or near atmospheric.
