Nafcillin is a beta-lactam antibiotic of penicillin class. As a beta-lactamase-resistant penicillin, it is used to treat infections caused by Gram-positive bacteria, in particular, species of staphylococci that are resistant to other penicillins.

Pralidoxime is a cholinesterase reactivator used as the antidote to organophosphate pesticides or acetylcholinesterase inhibitors (nerve agents) in conjunction with atropine and diazepam. Organophosphates bind to the esteratic site of acetylcholinesterase, which results initially in reversible inactivation of the enzyme. Acetylcholinesterase inhibition causes acetylcholine to accumulate in synapses, producing continuous stimulation of cholinergic fibers throughout the nervous systems. If given within 24 hours after organophosphate exposure, pralidoxime reactivates the acetylcholinesterase by cleaving the phosphate-ester bond formed between the organophosphate and acetylcholinesterase. Pralidoxime is indicated as an adjunct in the treatment of moderate and severe poisoning caused by organophosphate pesticides that have anticholinesterase activity or by chemicals with anticholinesterase activity such as some chemicals used as nerve agents during chemical warfare. Pralidoxime is also indicated as an adjunct in the management of the overdose of cholinesterase inhibitors, such as ambenonium, neostigmine, and pyridostigmine, used in the treatment of myasthenia gravis. Pralidoxime, used in conjunction with atropine, reverses nicotinic effects, such as muscle weakness and fasciculation, respiratory depression, and central nervous system (CNS) effects, associated with toxic exposure to organophosphate anticholinesterase pesticides and chemicals and with cholinesterase inhibitor overdose. Atropine, by antagonizing the action of cholinesterase inhibitors at muscarinic receptor sites, reverses muscarinic effects, such as tracheobronchial and salivary secretion, bronchoconstriction, bradycardia, and, to a moderate extent, CNS effects.

The selenite anion is a selenium oxoanion with the chemical formula SeO2−3. A selenite (Se) is a compound that contains this ion. Sodium selenite is an inorganic form of the trace element selenium with potential antineoplastic activity. It was documented that Se deficiency observed in some countries and/or geographic regions (e.g. Keshan region in China), is associated with an increased morbidity and mortality of neoplastic diseases. To correct this problem a number of organic and inorganic selenium compounds were developed and tested. However, it is now firmly established that only an inorganic sodium selenite with four-valent Se, and not that with six-valent (selenate) cation shows anticancer activity. Selenite can undergo redox reaction, for example with protein's sulfhydryl groups expressed on the surface of tumor cells. In this way selenite prevents non-enzymatic formation of parafibrin that coats tumors cells and hence presents them as 'self' to the innate cellular immune system. Consequently, macrophages of the lymphatic system do not recognize neoplastic cells as 'foreign' bodies and spare them from the immune destruction. Sodium selenite also showed promise as a cost-effective, nontoxic anti-inflammatory agent. Treatment with sodium selenite lowers reactive oxygen species (ROS) production, causes a spontaneous reduction in lymphedema volume, increases the efficacy of physical therapy for lymphedema, and reduces the incidence of erysipelas infections in patients with chronic lymphedema. Limited evidence has been presented though that intakes of selenium greater than the amount needed to allow full expression of selenoproteins may have chemopreventive effects against cancer. Controlled intervention studies are needed to fully evaluate selenium as a cancer chemopreventive agent. The US Food and Drug Administration approved a selenium supplement to animal diets; the most common form is sodium selenite for pet foods.

Lincomycin (LINCOCIN®) is an antibiotic produced by Streptomyces lincolnensis (Streptomycetaceae family). It has been used in the treatment of staphylococcal, streptococcal, and Bacteroides fragilis infections. Lincomycin (LINCOCIN®) inhibits protein synthesis in susceptible bacteria by binding to the 50S subunits of bacterial ribosomes and preventing peptide bond formation upon transcription. It is usually considered bacteriostatic, but may be bactericidal in high concentrations or when used against highly susceptible microorganisms.

Valproic acid (VPA; valproate; di-n-propylacetic acid, DPA; 2-propylpentanoic acid, or 2-propylvaleric acid) was first synthesized in 1882, by Burton. FDA approved valproic acid for the treatment of manic episodes associated with bipolar disorder, for the monotherapy and adjunctive therapy of complex partial seizures and simple and complex absence seizures and adjunctive therapy in patients with multiple seizure types that include absence seizures and for the prophylaxis of migraine headaches. The mechanisms of VPA which seem to be of clinical importance in the treatment of epilepsy include increased gamma-aminobutyric acid (GABA)-ergic activity, reduction in excitatory neurotransmission, and modification of monoamines. Recently, it was discovered that the VPA is a class I selective histone deacetylase inhibitor. This activity can be distinguished from its therapeutically exploited antiepileptic activity.
