... To investigate the relation between metabolism and toxicity of 1,2-dichlorobenzene (1,2-DCB), the biotransformation, tissue distribution, blood kinetics, and excretion at three different oral dose levels (5, 50 and 250 mg/kg) of the radiolabelled compound were investigated in the male Wistar rat. A toxic dose level (250 mg/kg...) was included. ... The concentration of parent chemical was essentially constant during 3 and 6 hr for the mid- and high-dose level respectively, and then declined. 1,2-DCB could only be detected in blood in the first 2 hr after administration of the 5-mg/kg dose. The major route of biotransformation was via the glutathione pathway and 60% of the urinary metabolites were mercapturic acids. In addition, the major metabolites in bile were conjugates of glutathione. Other major metabolites in urine were the sulfate conjugates of 2,3- and 3,4-dichlorophenol (DCP). No significant differences in metabolic profiles were observed between the different doses. Induction with phenobarbital resulted in the increased excretion of sulfate conjugates (30% in the induced rat, 20% in the control rat), mainly the conjugate of 3,4-DCP...
1,2-Dichlorobenzene gave 3,4-dichlorophenol with smaller amounts of 2,3-dichlorophenol, 3,4- and 4,5-dichlorocatechol and 3,4-dichlorophenylmercapturic acid also observed; 1,3-dichlorobenzene gave 2,4-dichlorophenol as the major product with 3,5-dichlorophenol, 3,4-dichlorocatechol, and 2,4-dichlorophenylmercapturic acid also identified; 1,4-dichlorobenzene gave 2,5-dichlorophenol as the major metabolite with 2,5-dichlorquinol identified as a minor product.

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Phenols and related compounds/
Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Administer activated charcoal ... . Do not use emetics. Cover skin burns with dry, sterile dressings after decontamination ... . Maintain body temperature. /Phenols and related compounds/
Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in severe respiratory distress. Positive pressure ventilation techniques with a bag valve mask device may be beneficial. Consider drug therapy for pulmonary edema ... . Monitor cardiac rhythm and treat arrhythmias if necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's (LR) if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors if patient is hypotensive with a normal fluid volume. Watch for signs of fluid overload ... . Administer 1% solution methylene blue if patient is symptomatic with severe hypoxia, cyanosis, and cardiac compromise not responding to oxygen. DIRECT PHYSICIAN ORDER ONLY ... Treat seizures with diazepam or lorazepam. ... Use proparacaine hydrochloride to assist eye irrigation ... . /Phenols and related compounds/

Synthesis and in vitro antimycobacterial and isocitrate lyase inhibition properties of novel 2-methoxy-2′-hydroxybenzanilides, their thioxo analogues and benzoxazoles
Mycobacterium avium 330/88, Mycobacterium kansasii 235/80, clinically isolated M. kansasii 6509/96 and the ability to act as in vitro isocitratelyase inhibitors. The best ICL inhibitors were two compounds from the thiobenzanilide group (8f, 8m), which exhibited an inhibition potential that was equal to the standard compound, 3-nitropropionic acid. In addition, the best antimycobacterial properties were
