  • Lung cancer is the leading cause of cancer-related deaths worldwide. Indigo Naturalis (IN) is a dark blue powder obtained by processing leaves or stems of indigo plants, its anticancer effects have been reported in several studies. However, the pharmacological mechanism of IN in small cell lung cancer (SCLC) is not elucidated. In this study, to investigate the anticancer efficacy of IN for SCLC, we presented potential active ingredients, SCLC-related targets, and pharmacological mechanisms of IN that are expected to have anticancer activity for SCLC using a network pharmacological analysis. The phytochemical compounds of IN have been collected through TCMSP, SymMap, or HPLC documents. The active ingredients of IN such as indirubin, indican, isatin, and tryptanthrin were selected through ADME parameters or literature investigations for each compound. Using the Compounds, Disease-Target associations Databases, 124 common targets of IN and SCLC were obtained. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) Pathway enrichment analysis was carried out. GO biological processes are associated with response to xenobiotic stimulus, positive regulation of protein phosphorylation, regulation of mitotic cell cycle, and regulation of apoptotic signaling pathway. KEGG disease pathways included Gastric cancer, Bladder cancer, SCLC, and Melanoma. The main anticancer targets of the IN for SCLC were analyzed in 14 targets, including BCL2, MYC, and TP53. In conclusion, the results of this study based on the network pharmacology of IN can provide important data for the effective prevention and treatment of SCLC.

  • A previous study in humans demonstrated the sustained inhibitory effects of donepezil on acetylcholinesterase (AChE) activity; however, the effective concentration of donepezil in humans and animals is unclear. This study aimed to characterize the effective concentration of donepezil on AChE inhibition and impaired learning and memory in rodents. A pharmacokinetic study of donepezil showed a mean peak plasma concentration of donepezil after oral treatment (3 and 10 mg/kg) of approximately $1.2{\pm}0.4h$ and $1.4{\pm}0.5h$, respectively; absolute bioavailability was calculated as 3.6%. Further, AChE activity was inhibited by increasing plasma concentrations of donepezil, and a maximum inhibition of $31.5{\pm}5.7%$ was observed after donepezil treatment in hairless rats. Plasma AChE activity was negatively correlated with plasma donepezil concentration. The pharmacological effects of donepezil are dependent upon its concentration and AChE activity; therefore, we assessed the effects of donepezil on learning and memory using a Y-maze in mice. Donepezil treatment (3 mg/kg) significantly prevented the progression of scopolamine-induced memory impairment in mice. As the concentration of donepezil in the brain increased, the recovery of spontaneous alternations also improved; maximal improvement was observed at $46.5{\pm}3.5ng/g$ in the brain. In conclusion, our findings suggest that the AChE inhibitory activity and pharmacological effects of donepezil can be predicted by the concentration of donepezil. Further, $46.5{\pm}3.5ng/g$ donepezil is an efficacious target concentration in the brain for treating learning and memory impairment in rodents.

  • The analgesic, anticonvulsant and anti-inflammatory actives of leaves of Hedera rhombea Bean were evaluated. The methanol and butanol fractions showed considerable analgesic activity, but no anticonvulsant activities. Anti-inflammatory activity was found in the methanol, butanol and ether fractions by carrageenin induced edema test.

  • Many plants and animal have long been known to have medicinal effects and therefore have been used as medicines. There are many substances that show various pharmacologic efficacy such as anti-tumor efficacy, anti-inflammatory efficacy, cholesterol-lowering efficacy, anti-coagulant of blood efficacy and anti-bacterial efficacy. I summarized the recent advances in research on physiologically functional foods. The pharmacological efficacy of dietary fiber, chitin & chitosan, DHA(docosahexaenoic acid), mushroom, alginic acid and herbs have selected as topices for discussion. I was examining the anti-coagulant activity of herbs, I discovered that Eugenia caryophyllata T. (clove) had a relatively high anti-coagulant activity.

  • Dongchunghacho (Dong-Chong-Xia-Cho in Chinese) is one of entomogenous fungi that grow as parasites mainly to pupae or larvae. It includes many different genera such as Cordyceps, Paecilomyces, Torrubiella and Podonectria. The ethanolic extract of Cordyceps scarabaeicola, prepared from its fruiting bodies, showed significant inhibitory activity on angiogensis, which was detected by chick embryo chorioallantoic membrane (CAM) assay. The ethanolic extract of media-cultured Paecilomyces japonica also showed significant anti-angiogenic activity in CAM assay. (omitted)

  • The general pharmacological properties of YJA20379-1 2-dimethylamino-4,5-dihydrothiazolo[4,5:3,4]pyridol[1,2-a]benzoimidazole, a novel proton pump inhibitor with antiulcer activities were investigated in mice, rats, guinea pigs and rabbits. YJA20379-2 at oral doses of 50, 100 and 200 mg/kg did not affect the general behaviour, hexobarbital hypnosis and motor coordination in mice. The drug did not have analgesic or anticonvulsant action at 200 mg/kg. Locomotor activity and body temperature were not influenced at 100 mg/kg. At a concentration up to 2{\times}10^{-4} g/ml$, YJA20379-2 did not produce any contraction or relaxation of isolated preparations, such as the rat fundus, the guinea pig ileum and the rat uterus, and did not antagonize the contractile response to several spasmogens, such as histamine, acetylcholine, serotonin and oxytocin. At dosages up to 200 mg/kg p.o. YJA20379-2 did not affect the pupil size of mice. Intestinal propulsion of mice was not affected up to 200 mg/kg p.o. and the drug did not affect urinary excretion at 100 mg/kg p.o. These results indicate that at dosages up to 100 gm/kg p.o. YJA20379-2 was found not to affect this pharmacological profile. However, at 200 mg/kg the drug lowered body temperature and showed decreased in locomotor activity and urine volume.

  • In order to investigate pharmacological properties of ι -muscone, effects of ι-muscone and musk on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in Mongolian gerbils. The histological observations showed a preventive effect of the ι-muscone treatment with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by the ι-muscone treatment. In contrast to what was seen with ATP, the lactate and lipid peroxide were both elevated in vehicle-treated ischemic gerbils.˙ This elevation was prevented by the ι-muscone treatment. While ι-muscone had no effects on the hexobarbital-induced sleeping time and the convulsions induced by electric shock, pentetrazol and strychnine, it had effect on rotarod test and spontaneous activity test. Respiration rate and depth were increased by the ι-muscone treatment. Furthermore, ι-muscone showed anti-stress effect. Our findings suggest that the pharmacological profile of ι-muscone on cerebral ischemia and central nervous system are similar to that of musk.

  • 'Kangsim-San' is an added and subtracted prescription of 'Cheongsim-Yeonza-Tang' recorded in 'Dongeuy-Soose-Boweon' from which it has become one of the favorate prescriptions at the Oriental Medical Hospital, Kyung-Hee University. It is described in the book that the 'Cheongsim-Yeonza-Tang' can be effective to symptoms relating to fatigue, nocturnal emission, abdominal pain, tongue deviation and palsy, etc. However the 'Kangsim-San' has been used for neurotic syndrome, pulpitation, insomnia, constipation, dry-mouth, auorexia and arrythmias and so on, added to the above-mentioned symptoms for the 'Cheongsim-Yeonza-Tang' at the hospital. Nevertheless, the pharmacological research of fundamental basis is not completed so far, and we have attempted experiment on various animals to study the pharmacological effects of the medicine. The result was proved as follows; The prescription had a considerable effects on the sedation of central nervous system, antipyretic and analgesic action, and vasodilative action.
