• INCLUSION CRITERIA:
• Patients must have histologically confirmed solid tumor malignancy or lymphoma that is metastatic or unresectable and for which effective therapy does not exist or is no longer effective.
• Any prior chemotherapy therapy is allowed in this protocol. Patients must be greater than or equal to 4 weeks from prior radiation or cytotoxic chemotherapy, except greater than or equal to 6 weeks for mitomycin C and nitrosoureas; greater than or equal to 2 weeks from hormonal therapy; greater than or equal to 4 weeks from prior experimental therapy; greater than or equal to 4 weeks from monoclonal antibody therapy (cetuximab, bevacizumab), greater than or equal to 2 weeks from sorafenib, sunitinib or temsirolimus and greater than or equal to 8 weeks from prior UCN01 treatment. Patients with prostate cancer may continue ongoing LHRH agonist therapy. Patients with bone metastases or hypercalcemia who began intravenous bisphosphonate treatment prior to study entry may continue this treatment.
• Age greater than or equal to 18 years. Because no dosing or adverse event data are currently available on the use of dimethane sulfonate in patients < 18 years of age, children are excluded from this study but will be eligible for future pediatric phase 1 single-agent trials.
• ECOG performance status 0-2 (Karnofsky greater than or equal to 60%,).
• Life expectancy of 3 months or greater.

• Patients must have acceptable organ and marrow function as defined below:

  • leukocytes greater than or equal to 3,000/mm(3)
  • absolute neutrophil count greater than or equal to 1,500/ mm(3)
  • platelets greater than or equal to 100,000/ mm(3)
  • total bilirubin within normal institutional limits
  • AST(SGOT)/ALT(SGPT) less than or equal to 2.5 X institutional upper limit of normal
  • creatinine within normal institutional limits OR
  • creatinine clearance > 50 mL/min/1.73 m(2) for patients with creatinine levels above institutional normal.
• The effects of dimethane sulfonate on the developing human fetus are unknown. For this reason and because alkylating agents are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for at least 3 months after study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
• Ability to understand and the willingness to sign a written informed consent document.
• Willing to comply with study procedures and follow-up.

EXCLUSION CRITERIA:

• Patients who have not recovered (CTC less than or equal to grade I) from adverse events due to prior treatments
• Patients may not be receiving any other investigational agent with therapeutic anticancer intent.
• Patients with history of CNS metastasis, unless control has been achieved with either radiation or surgical resection at least 6 months prior to enrollment on study.
• Patients who have had radiation to the pelvis or other bone marrow-bearing sites will be considered on a case by case basis and may be excluded if the bone marrow reserve is not considered adequate (> 25% of bone marrow irradiated).
• Uncontrolled medical illness including, but not limited to, ongoing or active infection, chronic or acute hepatitis, renal failure, symptomatic congestive heart failure, myocardial infarction within the last 6 months, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
• Pregnant women are excluded from this study because DMS612 is likely to have toxicities similar to the alklyating agents with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with DMS612, breastfeeding should be discontinued if the mother is treated with DMS612.
• HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with DMS612. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.
• Patients are not eligible for the study if taking cytochrome P450-inducing anticonvulsants. This applies to patients with brain metastasis or those taking anticonvulsant for another reason (ie. Epilepsy).
• Patients diagnosed with alcoholism may not be treated with disulfiram.
• Patients may not be receiving agents thought to inhibit or induce the cytochrome p450 isoenzyme CYP3A4.
