/EXPL THER/ A brief historical resume is presented on the use of dithiocarbamates for the treatment of persons exposed to nickel carbonyl. The specificity of the treatment is demonstrated in an industrial accident in which four men were simultaneously exposed to nickel carbonyl vapors. Three of the men received dithiocarb within 24 hours after exposure and the fourth was hospitalized by his family physician and treated for bronchopneumonia with antibiotics and without benefit of dithiocarb. The three workmen who received dithiocarb became symptomless and returned to work within 72 hours after exposure. The fourth man who had not received dithiocarb died within five days after exposure.

/EXPL THER/ We randomized 389 symptomatic patients with human immunodeficiency virus (HIV) infection to ditiocarb sodium (400 mg/cu m orally for 24 weeks) or a placebo. Patients were well balanced according to Centers for Disease Control (CDC) group, CD4+ cell number, and duration of disease prior to entry. Ten new acquired immunodeficiency syndrome (AIDS)-defining opportunistic infections occurred in the treated patients and 21 in the controls. Reduction of new opportunistic infections in the ditiocarb group was significant in all patients (relative risk [RR], 0.44) and in patients with AIDS (CDC groups IV-C1 and IV-D) (RR, 0.12). The size of the effect of ditiocarb was maintained when data were reanalyzed after exclusion of a patient who progressed to Pneumocystis carinii pneumonia who was not strictly CDC-defined (RR, 0.46), or when considering as new opportunistic infections three events, which were clinically active at entry, but for which the definitive diagnosis was made during study (RR, 0.49). The administration of ditiocarb did not induce any major adverse clinical or biological reactions. We conclude that, in this study, ditiocarb was safe and reduced the incidence of opportunistic infections in patients with symptomatic HIV infection.

5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Chelating Agents

Chemicals that bind to and remove ions from solutions. Many chelating agents function through the formation of COORDINATION COMPLEXES with METALS. (See all compounds classified as Chelating Agents.)


Adjuvants, Immunologic

Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity. (See all compounds classified as Adjuvants, Immunologic.)


Antiviral Agents

Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly. (See all compounds classified as Antiviral Agents.)


5.2 Absorption, Distribution and Excretion

Rats receiving levels of 500 mg of dithiocarb in 1-2 mL water/kg body weight by gavage reached plasma levels of 2 mg/L dithiocarb in 3 hours.

A half life for absorption of 26 minutes was determined when S-dithiocarb dissolved in 2M phosphate buffer was injected into the small intestinal lumen of adult male Wistar rats at a dose of 25 mg/kg.

Within 15 minutes of dosing rats with 25 mg (222 moles S)/rat S-dithiocarb i.p., nonprotein bound radiolabel was detected in the plasma (1561 nmoles/mL plasma) and in the liver (3211 nmoles/g liver). A substantial amount (>45% within 15 minutes of dosing) of radioactivity also was found to be bound reversibly to soluble proteins of liver and plasma.

A small amount (<0.1%) of unchanged dithiocarb was detected in the urine of rats receiving ip injections of 25 mg (35)S-dithiocarb/rat. One hr after dosing, 96.1% of the radiolabeled urinary metabolites was of S-glucuronide conjugate and 3.9% inorganic sulfate. Within 1 hr after dosing, 7% of the administered (35)S-dithiocarb was recovered as carbon disulfide in the expired air.

5.3 Metabolism/Metabolites

In rats, four metabolites, diethyldithiocarbamate, diethyldithiocarbamate-s-glucuronide, inorganic sulfate and carbon disulfide were identified; these are also metabolites of disulfiram.

5.4 Mechanism of Action

Although the ability of disulfiram to inactivate CYP2E1 has been known for more than 20 years, the mechanism has not yet been elucidated. A metabolite of disulfiram, diethyldithocarbamate (DDC), is converted by CYP2E1 to a reactive intermediate that subsequently inactivates the protein, leading to mechanism-based inactivation. Mass spectral analysis of the inactivated human 2E1 protein demonstrates that the inactivation is due to the formation of an adduct of the reactive metabolite of DDC with the apoprotein. These data, along with mass spectral analysis of a reactive intermediate trapped with GSH, indicate the involvement of a reactive intermediate with a molecular mass of 116 Da. Our results suggest that this binding involves formation of a disulfide bond with one of the eight cysteines in CYP2E1. The inactivation of wild-type CYP2E1 as well as two of its polymorphic mutants, CYP2E1*2 and CYP2E1*4, was also investigated. For wild-type CYP2E1, the K(I) was 12.2 uM and the k(inact) was 0.02 min(-1). The K(I) values for the two polymorphic mutants were 227.6 and 12.4 uM for CYP2E1.2 and CYP2E1.4, and the k(inact) values were 0.0061 and 0.0187 min(-1), respectively. These data indicate that DDC is a much less efficient inactivator of CYP2E1.2 than it is of either the wild-type or the CYP2E1.4 variant.
