Background: : A new series of O-benzyloximes derived from eugenol was synthesized and was evaluated for its antinociceptive and anti-inflammatory properties. Methods: : The target compounds were obtained in good global 25-28% yields over 6 steps, which led us to identify compounds (Z)-5,6-dimethoxy-2,2-dimethyl-2,3-dihydro-1H-inden-1-one-O-(4- (methylthio)benzyloxime (8b), (Z)-5,6-dimethoxy-2,2-dimethyl-2,3-dihydro-1H-inden-1-one-O-4- bromobenzyloxime (8d) and (Z)-5,6-dimethoxy-2,2-dimethyl-2,3-dihydro-1H-inden-1-one-O-4- (methylsulfonyl)benzyloxime (8f) as promising bioactive prototypes. Results:: These compounds have significant analgesic and anti-inflammatory effects, as evidenced by formalin-induced mice paw edema and carrageenan-induced mice paw edema tests. In the formalin test, compounds 8b and 8f evidenced both anti-inflammatory and direct analgesic activities and in the carrageenan-induced paw edema, with compounds 8c, 8d, and 8f showing the best inhibitory effects, exceeding the standard drugs indomethacin and celecoxib. Conclusion: : Molecular docking studies have provided additional evidence that the pharmacological profile of these compounds may be related to inhibition of COX enzymes, with slight preference for COX-1. These results led us to identify the new O-benzyloxime ethers 8b, 8d and 8f as orally bioactive prototypes, with a novel structural pattern capable of being explored in further studies aiming at their optimization and development as drug candidates.

Background: Lichens which are betide to mangroves are termed as Manglicolous Lichens (ML). As these ML are habituated under stress conditions, they are screened for unique metabolites and biological activities. Objective: The study aimed to establish the chemical and biological profile of ML, Graphis ajarekarii. Methods: The Ethyl Acetate Extract of G. ajarekarii (EAE) was subjected to chromatographic techniques and the obtained isolates were characterized by spectroscopic analysis. The hydroalcoholic extract of G. ajarekarii (AE), EAE, isolates and Hydroalcoholic Extract of host (HE) were evaluated for fibrinolytic (fibrin clot method), in vitro (protein denaturation method) and in vivo (formalin-induced rat paw oedema assay), anti-inflammatory and cytotoxicity (MTT assay) activities. Results: Chemical investigation of the EAE led to the isolation of two known compounds namely atranorin (1) and ribenone (2), which were confirmed by spectral data. The AE and EAE gradually lysed the fibrin clot with 94.54 and 65.07%, respectively, at 24 h. The AE inhibited protein denaturation of about 88.06%, while the standard (Indomethacin) with 93.62%. Similarly, the in vivo antiinflammatory analysis of AE (200 mg/mL) showed potent reduction of rat paw oedema than the standard, whereas EAE and 1 depicted moderate depletion. In addition, the AE revealed prominence inhibition on MCF-7, DU145 and K-562 with IC50 values of 69.5, 42.5 and 38 µg/mL, respectively, whereas the HE exhibited mild inhibitory profile against fibrin clot, inflammation and cancer. Conclusion: From the results, it can be concluded that the G. ajarekarii has an aptitude to act against coagulation, inflammation and cancer cells.

Solidago virgaurea L. is a perennial plant used in European traditional medicine as a diuretic or a remedy for inflammatory conditions of the urinary tract but also for gout, especially in the Balkans. The present study was focused on a preclinical, in vivo evaluation of antihyperuricemic, anti-inflammatory, and antihypertensive effects of a dry extract from S. virgaurea L. (ESV). Colorimetric and HPLC–MS techniques were used to identify the main chemical constituents of ESV. Antihyperuricemic effect of ESV was assessed in a rat model of hyperuricemia induced by the administration of potassium oxonate. Antihypertensive effect of ESV was evaluated in hyperuricemic rats by monitoring systolic blood pressure with a non-invasive blood-pressure recording system. The anti-inflammatory effect of ESV was tested using a rat model of paw edema. The main chemical constituents of ESV were rutin and phenolic acids represented by chlorogenic and caffeic acid. ESV demonstrated significant antihyperuricemic effects in rats due to an uricosuric mechanism. Additionally, ESV reduced the progression of arterial hypertension in hyperuricemic rats and also showed anti-inflammatory properties slightly inferior to diclofenac. The results suggest that ESV could be a natural remedy for the treatment of gout and protection against endothelial dysfunction caused by hyperuricemia.

Aegle marmelos (Bilva) is being used in Ayurveda for the treatment of several inflammatory disorders. The plant is a member of a fixed dose combination of Dashamoola in Ayurveda. However, the usage of roots/root bark or stems is associated with sustainability concerns. Bael (Aegle marmelos (L.) Corr.) is an important medicinal plant of India. Leaves, fruits, stem and roots of A. marmelos have been used in ethno medicine to exploit its' medicinal properties including astringent, antidiarrheal antidysenteric, demulcent, antipyretic and anti-inflammatory activities. Compounds purified from bael have been proven to be biologically active against several major diseases including cancer, diabetes and cardiovascular diseases. Preclinical studies indicate the therapeutic potential of crude extracts of A. marmelos in the treatment of many microbial diseases, diabetes and gastric ulcer. This review covers the biological activities of some isolated chemical constituents of A. marmelos and preclinical studies on some crude extracts and pure compounds to explore novel bioactive compounds for therapeutic application. Aegle marmelos (L.) is a seasonal fruit that contains significant amounts of bioactives like, phenolic acids (gallic acids, 2,3-dihydroxy benzoic acid, chlorogenic acid, p-coumaric acid, vanillic acid), flavonoid (rutin), organic acids (oxalic acid, tartaric acid, malic acid, lactic acid, acetic acid, citric acid, propionic acid, succinic acid, fumaric acid), vitamin C, vitamin B group (thiamine, niacin, pyridoxine, pantothenic acid, biotin, cobalamins, riboflavin), tocopherols (α-tocopherol, β-tocopherol, γ-tocopherol, δ-tocopherol), carotenes (α-carotene, β-carotene, γ-carotene, δ-carotene) and also rich in essential minerals (potassium, calcium, phosphorus, sodium, iron, copper, manganese). Hence the use of aegle plays important role as anti-inflammatory.
