PRIORITY CLAIM

This application claims priority to U.S. Provisional Patent Application Ser. No. 61/773,798, filed Mar. 6, 2013, which is incorporated herein by reference in its entirety, as if fully set forth herein.

BACKGROUND

Hematological cancer includes leukemia, lymphoma, and myeloma. Leukemia is a type of cancer of blood or bone marrow characterized by an abnormal increase of immature leukocytes. The exact cause of leukemia is unknown; however, it generally results from DNA mutations in stem cells.

Leukemia is the most common malignant tumor in children (Leukemia in Children). Among all cancers, leukemia is most common and the leading cause of death for children and teens under 20 years old (Blood Cancers: Leukemia, Lymphoma, and Myeloma). Although leukemia can be classified into a large variety of groups, one of the most commonly used methods is to classify leukemia into four major subtypes: acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), acute myelogenous leukemia (AML) and chronic myelogenous leukemia (CML) (Types of Leukemia, National Cancer Institute).

Since it is not possible to remove leukemia via surgery, standard treatment options for leukemia are chemotherapy and radiotherapy. Among the four major subtypes, CML may be treated with the introduction of imatinib (Gleevec) into chemotherapy with some success. Unfortunately, CML only accounts for about 15% of adult leukemia (Faderl et al, 1999). Other leukemia patients still rely on traditional chemotherapeutic drugs (e.g., cisplatin), most of which are cytotoxic in nature.

Cytotoxic drugs act to disrupt cell proliferation by directly destroying cellular DNA, incorporating into the DNA template and interfering with DNA synthesis, inhibiting microtubule assembly/disassembly, impairing nucleic acid synthesis, or disrupting protein synthesis. Unfortunately, cytotoxic drugs function in a non-specific manner and kill both cancer cells and normal cells, resulting in severe adverse side effects for patients. Further, by interfering with DNA synthesis, cytotoxic drugs may also induce new DNA mutations that could result in the occurrence of new cancers (Carew et al., 2003; Sturm et al., 2003).

Given the lack of an effective treatment option and the negative side effects associated with current treatment options there is a need to develop a new generation of target-specific drugs for the treatment of leukemia and other cancers with improved therapeutic benefits and reduced side effects.

EXAMPLES Example 1 Effect of Compounds on the Growth of a Variety of Leukemia Cell Lines

Methods

Treatment of Cells.

Various human leukemia cells were grown to the logarithmic growth phase and seeded into 24-well plates. Plated cells were incubated at 37° C. in a 5% CO2 humidified incubator for 24 hours and treated with various concentrations of YT30 or other compounds disclosed herein. Treated cells were further incubated for 72 hours and then were examined for cell proliferation. Cell proliferation was determined using the CellTiter-Glo Luminescence Cell Viability assay (Promega Corporation, Madison, Wis.) according to the manufacturer's protocol. The calculated inhibition rate was determined with the following formula: Inhibition rate (%)=(1−Luminescence of experimental group/Luminescence of control group)×100. IC50 is the calculated concentration of a compound needed to inhibit half of the maximum cell growth (equivalent to cell growth in control group) based on the corresponding dose-response curve under the described experimental conditions.

Results

YT30 Inhibits Cell Proliferation of Numerous Leukemia Cell Lines.

Table 7 provides the YT30 IC50 (μM) concentrations for inhibiting various leukemia cell lines. YT30 inhibited the proliferation of all leukemia cell lines tested. The strongest YT30 cell growth inhibition was observed in the Jurkat, HL60, RS4, MOLT-4, and SEM leukemia cells under the described experimental conditions.

FIG. 1 shows that treatment of REH, HL60, and Nalm-6 leukemia cells with 4 μM of YT30 was sufficient to significantly inhibit cell growth. In contrast, treatment of the same cells with 4 μM of the inactive YT19 failed to inhibit cell growth. The structure of the inactive YT19 compound is:

Example 2 Compound YT30 Significantly Inhibited Disease Progression in BALB/c Nude Mice with Acute B Cell Lymphoblastic Leukemia and Increased the Lifespan of Those Mice

Methods

Inducing B Cell Lymphoblastic Leukemia in BALB/c Nude Mice and Treatment with YT30.

BALB/c nu/nu nude mice were 4 to 5 weeks old with an average weight of 22.4±1.03 grams. The mice were raised under specific pathogen-free (SPF) conditions and had access to food and water freely. Cyclophosphamide at about 130 mg/kg per day was administrated with intraperitoneal (IP) injection for 2 days. Twenty-four hours later, a suspension of 3.5×106 or 5×106 Nalm-6 cells (0.2 mL) were injected through tail vein of each BALB/c nude mouse. Five days later, the mice were randomly divided into a YT30 treated group (n=5) and a solvent control group (n=5).

Mice in the YT30 treated group were intraperitoneally injected with 200 μL of YT30 (50 mg/kg) once a day, for 5 days a week, and for 3 or 4 weeks. The mice in the solvent control group were intraperitoneally injected with the same volume of solvent (20% DMSO, 80% of 20% w/v (2-hydroxypropyl)-β-cyclodextrin in PBS), and were on the same treatment schedule as the YT30 treated group. The body weights of the mice were recorded prior to the start of the treatment and at least twice a week thereafter. The dosages were adjusted according to the body weight to conform to the 50 mg/kg/day treatment plan. Each mouse of every group was also monitored daily for any other symptoms of side effects including change in behavior, activity or posture, areas of redness and swelling, and food and water withdrawal. The mice were euthanized when moribund or if weight loss was more than 20% during the experiment. Dates of death were recorded.

Results

YT30 significantly extended the survival time of BALB/c nude mice with acute lymphoblastic leukemia (Table 9 and FIG. 2). The mice in the control group developed hind limb paralysis and hunch back with disease progression at approximately 28 days. Mice in the control group also had rapid weight loss, reduced activity, loss of appetite and lack of energy. The general conditions of the YT30 treated group were significantly better than the control group throughout the course of treatment. The average life span of the 3 week YT30 treated group was 48.8±9.7 days in contrast to 36.6±3.9 days for the control group with mice in both groups having received an inoculation of 5×106 Nalm-6 cells (Table 9). When the mice were inoculated with 3.5×106 Nalm6 cells, the median survival time for the mice was 45 days for the control group and >340 days for the YT30 treated group (Table 9). The median survival time was used instead of average survival time because three out of five mice in the YT30 treated group appeared to be cured. These three mice were euthanized 341 days after treatment was started.

The results demonstrated that YT30 significantly inhibited leukemia progression in Balb/c nude mice. Moreover, the data shows that YT30 treatment at an early stage of leukemia development further increased life span and decreased disease progression even more. All of the data were analyzed with Microsoft Excel or SPSS14.0 statistical software count data using the x±s. The difference between the groups was statistically significant with P<0.05.

Example 3 YT30 and Other Transcription Modulators Inhibited the Growth of Many Different Cancer Cells Lines

YT30 was tested for growth inhibition against 67 human cancer cell lines derived from diverse tissues including the National Cancer Institute human cancer cell lines (NCI-60). These cell lines were grown to the logarithmic growth phase and seeded into 96-well plates. Plated cells were incubated at 37° C. in a 5% CO2 humidified incubator for about 24 hours. Cells in different wells were treated with various concentrations of YT30, YT86, YT88, or YT128. Treated cells were further incubated for 72 hours and then were examined for cell viability. Cell viabilities were determined by the CellTiter-Glo Luminescence Cell Viability assay kit (Promega Corporation, Madison, Wis.) according to manufacturer's protocol. Cell growth inhibition rates were determined by the following formula: Inhibition rate (%)=(1−Luminescence of compound treated group/Luminescence of DMSO control group)×100. IC50 is the calculated concentration of a compound needed to inhibit half of the maximum cell growth (equivalent to cell growth in control group) based on the corresponding dose-response curve under the described experimental conditions.

Results

YT30 growth inhibition was detected in 49 of the 67 human cancer cell lines (Table 10). YT30 inhibited the growth of breast, central nervous system (CNS), colon, prostate, non-small cell lung cancer (NSCLC), leukemia, renal, ovarian, melanoma, liver, and cervical cancer cell lines (Table 10).

Example 4 Combination Therapy of YT30 and Imatinib Inhibited Leukemia

Growth inhibition experiments were performed as previously described. The combination of YT30 and imatinib displayed a synergistic effect in growth inhibition of a Nalm-6, a leukemia cell line. After 72 hrs, combination of YT30 and Imatinib showed an increase in growth inhibition compared to addition of each agent alone (Table 13). For example, 1 μM YT30 alone induced growth inhibition by 8.4%, 10 μM imatinib induced growth inhibition by 44%, but the combination of 1 μM YT30 and 10 μM imatinib induced growth inhibition by 97%. The synergistic effects were also observed when the YT30 and imatinib were combined with other concentrations.

Example 5 YT30 Inhibition of Subcutaneous Leukemia Tumor Growth in Mouse Model

Tumor Transplantation and Treatment of NOD/SCID Mice.

Female Nonobese Diabetic/Severe Combined Immunodeficiency (NOD/SCID) mice that were 4-6 weeks old were used in the experiment. The mice were fed under specific pathogen free (SPF) conditions. Food and water were available to the mice at will. A suspension of 1×107 cells per mouse B-myelomonocytic leukemia MV4-11 cells (0.2 mL) in logarithmic phase were inoculated subcutaneously into the right back of the NOD/SCID nude mice.

The general conditions of the mice and the growth of the transplanted tumor were monitored. When the transplanted tumor grew to about 100 mm3 in size, the NOD/SCID mice were divided into four groups with five mice in each group so that each group of mice had a similar average tumor size. The control group received an intraperitoneal (IP) injection of 0.2 mL of solvent (20% DMSO, 80% of 20% w/v (2-hydroxypropyl)-β-cyclodextrin made in PBS). The imatinib group received gavage of 100 mg/kg/day imatinib. The high dosage group received an intraperitoneal injection of 50 mg/kg/day of YT30 (0.2 mL in volume) suspended in solvent (20% DMSO, 80% of 20% w/v (2-hydroxypropyl)-β-cyclodextrin made in PBS), while the low dosage group received IP injection of 25 mg/kg/day YT30 (0.2 mL in volume). Frequency of the administration was once per day and the experiment lasted 27 days after treatment started.

The body weights of the mice were recorded prior to the start of treatment and twice every week thereafter. Each mouse of every group was monitored daily for any other symptoms of side effects including change in behavior, activity or posture, areas of redness and swelling, and food and water withdrawal. Caliper measurements of the longest perpendicular tumor diameters were performed every 2 days to estimate the tumor volume; the following formula: 4π/3×(width/2)2×(length/2) was used to calculate the three-dimensional volume of an ellipse. The tumor inhibition rate was calculated according to tumor volume: Tumor inhibition rate by size (%)=(Tumor volume of the control group−Tumor volume of the treated group)/Tumor volume of the control group×100. The BALB/c nude mice were euthanized on the next day after the final injection and the subcutaneous tumor nodules were taken out intact and weighed. Tumor inhibition rate by weight (%)=(Tumor weight of the control group−Tumor weight of the treated group)/Tumor weight of the control group×100.

Results

YT30 inhibited the growth of subcutaneously transplanted leukemia tumors in NOD/SCID mice. About one week after seeding the NOD/SCID mice with MV4-11 cells, all of the transplanted tumors grew to a size around 100 mm3. The rate of successful transplantation was 100%. After 27 days of treatment with YT30, tumor growth inhibition by size is 58.8% for the high dosage YT30 treatment group and 38.8% for the low dosage YT30 treatment group (Table 14). The difference in tumor growth inhibitions between the high dosage and the low dosage group demonstrated clear dose-response relationship. The tumor weight was also significantly less than that of the control group, and the difference was statistically significant.
