The crude ethanolic extract of the leaves of Clerodendrum viscosum (Family: Verbenaceae) was evaluated for its antioxidant and analgesic activities to investigate the scientific basis of the traditional uses. The antioxidant property of the extract was assessed by 1, 1-diphenyl -2- picryl hydrazyl (DPPH) free radical scavenging assay. The extract showed prominent antioxidant activity ($IC_{50}about{\sim}16{\mu}g/ml$) which was comparable to standard drug ascorbic acid ($IC_{50}about{\sim}15{\mu}g/ml$).The extract produced significant (P<0.001) writhing inhibition in acetic acid induced writhing in mice at the dose of 125 mg, 250 mg and 500 mg/kg body weight respectively, which were comparable to the standard drug diclofenac sodium. The results tend to suggest that the crude leaves extract at the above doses have antioxidant and analgesic activities and indicate that it might possess biologically active constituents having free radical scavenging and analgesic activities respectably.

Chang-Back-San and Chil-Mi-Chang-Back-San have been used for the treatment of neuralgia and arthritis in traditional medicine. The anti-inflammatory activities of Chang-Back-San and Chil-Mi-Chang-Back-San water extract (CBSE and CCBSE) on the carrageenin induced edema, Corton oil induced granuloma pouch, and adjuvant arthritis in rats were examined. The analgesic effects of the CBSE and CCBSE were also investigated utilizing acetic acid induced writhing syndrome in mice. The oral administration of CBSE and CCBSE showed to have the anti-inflammatory activities in 1% carrageenin induced edema in rats. They also showed significant inhibitory effects on granuloma and exudate formation in rats. In the method of adjuvant arthritis, they orally administered for 19 days, inhibited the hind paw edema in rats from 3rd day to 19th day, especially CCBSE has the efficacy more than CBSE. They significantly decreased the number of writhing syndromes induced by acetic acid in mice. In the present study, CBSE and CCBSE were indicated to have the anti-inflammatory and analgesic activities.

The synthesis of phenoxyalkanoic acid derivatives and their anti-inflammatory and analgesic activities are described. Analysis of structure-activity relationships shows that in trichlorophenoxy derivatives anti-edematous potency is associated with the presence of 1-thiopropyl moiety and 2 or 40aminopyridyl moiety at $R^{l}$ position contributes to the analgesic activity.

The evaluation of the anti-inflammatory analgesic and antipyretic activities of loxoprofen sodium given in intramuscular route was investigated as compared to oral application in rats and mice. The intramuscular $ED_{50}$ values of loxoprofen sodium in carrageenan edema and vascular permeability tests are 1.15 and 7.8 mg/kg, respectively, which represent more potent than in case of oral application. Its therapeutic effects in adjuvant arthritis were shown at 6 mg/kg l.m. and 3mg/kg p.o. Analgesic effect was shown to be more potent as given intramuscularly. Similar potency of antipyretic effects was shown in both administration routes. Considerably weak gastric damages were observed in intramuscular application.

Three 1,2-benzothiazine derivatives were synthesized, and their analgesic / anti-inflammatory efficacy and their effect s of gastric irritation were evaluated. Among the three compounds, 39 exhibited the most potent anlagesic action, but the effect was weaker than that of piroxicam. Nonetheless, the compound showed 4 times more potent analgesic action with less gastric damage than did ibuprofen. These compounds did not show anti-inflammatory effect at an oral dose of 5 mg/kg.

Some pharmacological activities of acanthoic acid, isolated from Acanthopanax koreanum root was investigated in animals. It is revealed that the compound had analgesic and anti-inflammatory activities without actions on central nervous system and showed inhibition of lipid peroxidation. The anti-inflammatory activity might be related to inhibition of prostaglandin E$_2$ synthesis in exudates of inflammation.

The present investigation deals with the synthesis of some new salicylamidoacetyl sulfonamides 3a,b, salicylamido ethylacetate 4, salicylamido acetic acid hydrazide 5, which is considered as the key intermediate for the synthesis of several series of new compounds such as salicylamido pyrazol 6 and pyrazolone 1. N-imido-derivatives 9, 10, 11, thiadiazole 13, oxadiazole 14, 15, Schiffs bases 16a-f. Cyclocondensation of Schiffs bases with thioglycolic acid gave thiazolidinone 18a-c while with acetylchloride afforded azitidinones 19a-c and with acetic anhydride gave 1,4-benzoxazepine-3,5-dione. Some of the compounds were tested for their analgesic and antiinflammatory activities as well as ulcerogenic effects. Some derivatives were more effective than salicylamide and ulcerogenic activity was variably lowered .

For developing plant anti-inflammatory agents, extracts from Lonicera japonica were obtained and evaluated for their anti-inflammatory and analgesic activities using acute/chronic inflammatory models and writhing tests. It was found that the extracts with a modified extraction method showed higher anti-inflammatory and analgesic activities than those of the extracts based on the ancient literatures.

The crude ethanol extract of the stem bark of Trewia polycarpa (Family: Euphorbiaceae) was subjected to acetic acid induced writhing inhibition, Brine Shrimp lethality bioassay and 1, 1-diphenyl-2-picryl hydrazyl free radical scavenging assay for screening of analgesic, cytotoxic and antioxidant activity respectively. The extract produced significant (P < 0.001) writhing inhibition in acetic acid induced writhing in mice at the dose of 125, 250 and 500 mg/kg body weight respectively, which were comparable to the standard drug diclofenac sodium. The extract showed significant lethality to Brine Shrimp and the $LC_{50}$ value was $8\;{\mu}g/ml$. The extract showed prominent free radical scavenging activity ($IC_{50}$ about ${\sim}10\;{\mu}g/ml$) compare to standard drug ascorbic acid ($IC_{50}about\;{\sim}15\;{\mu}g/ml$). The results tend to suggest that the crude ethanol extract of the bark might possess analgesic, cytotoxic and antioxidant activities or active constituent(s) responsible for the activities.
