In general, this literature review indicates that epsilon-caprolactam has a relatively low toxicity to humans. This low-degree of toxicity is attributable in part to its rapid elimination as demonstrated by experimental studies on animals. Human studies are mostly those based on workers in Russian factories. Although reporting physicians attributed such symptoms as general weakness, irritability, headaches, and insomnia, and such diagnoses as neurosis, neurasthenia, rapid mood shifts as well as others to excessive caprolactam exposures, the widely recognized Russian national scourge of alcoholism, particularly among working populations was not considered as a possible factor. Some of the reports recognized the complicating existence of multiple exposures in the factories such as excessively high temperatures and humidity, high noise levels, and other chemicals - including mixtures of diphenyl and diphenyl oxide, cyclohexane, benzene, and others, but most reports gave scant or no consideration to them.

The effect of oral N-(4-chlorophenyl)-N-[1-(1-methylethyl)-4-piperidinyl]benzene acetamide (lorcainide) was studied in 12 patients with frequent and stable ventricular arrhythmias resistant to a number of other antiarrhythmic agents. Ambulatory electrocardiograms were obtained before and during treatment with lorcainide and in some patients after discontinuation of the drug. Lorcainide suppressed ventricular premature contractions by more than 90% in all but one patient. The daily doses were 200 mg (N = 8), 300 mg (N = 1), 400 mg (N = 1)and 600 mg (N = 2). Plasma concentrations of lorcainide and of the dealkylated metabolite ranged from 0.13 to 0.27 microgram/ml and 0.25 to 0.95 microgram/ml, respectively. Side effects such as insomnia and excessive perspiration were seen in 7 and 3 patients, respectively. Lorcainide is an effective antiarrhythmic agent against ventricular arrhythmias otherwise difficult to treat.

Primula macrophylla (Primulaceae) is reported as to be useful in asthma, restlessness, insomnia and fish poisoning. Antifungal and toxic activities of crude extract, fractions and a pure isolated compound exhibited statistically significant activities. Excellent antifungal activity was found in the crude extract, benzene and ethyl acetate fractions against T. longifusis and against M. canis with different MIC values. Antileishmanial activity (IC(50) = 50ug/mL) was observed as compared to standard drug Amphotericin B, and cytotoxic activity (LD(50) = 47.919microg/mL) was also found in the chloroform fraction. While pure compound 2-phenylchromone (Flavone) isolated from the chloroform fraction showed good activity (IC(50) = 25microg/mL) against Leishmania and cytotoxicity (LD(50) = 2.0116 microg/mL) in Brine Shrimp experiments. From antileishmanial and cytotoxic activity it can be concluded that 2-phenylchromone is the major compound responsible for these activities.

Hexahydroindenopyridine (HHIP) is an interesting tricyclic piperidine nucleus that is structurally related to melatonin, a serotonin-derived neurohormone. Melatonin receptor ligands have applications in several cellular, neuroendocrine and neurophysiological disorders, including depression and/or insomnia. We report herein an efficient two-step method to prepare new HHIP via enamine C-alkylation-cyclization. The influence of substituents on the benzene ring and the nitrogen atom on melatoninergic receptors has been studied. Among the 25 synthesized HHIPs, some of them containing methylenedioxy (series 2) and 8-chloro-7-methoxy substituents (series 4) on the benzene ring revealed affinity for the MT1 and/or the MT2 receptors within the nanomolar range or low micromolar. Similar activities were also encountered for those presenting urea (4g), N-aryl (2e) and N-alkyl (2f) acetamide functions. Therefore, new synthesized compounds with a HHIP nucleus have emerged as new promising leads towards the discovery of melatoninergic ligands which could provide new therapeutic agents.
