: The present work reports synthesis and screening of fifteen 2,5-disubstituted-4-thiazolidinones with different substitutions of varied arylidene groups at imino. The structures of the compounds were confirmed by spectral characterization. The compounds were subjected to in vivo anti-inflammatory and in vitro antioxidant activities. The derivatives possessed remarkable activities quite close to standard drugs used. Unlike conventional non-selective NSAIDs, the synthesized compounds did not contain any acidic group, thereby ensuring a complete cure from ulcers. To further substantiate the claim for safer derivatives, the active compounds were docked against the cyclooxygenase (COX)-2 enzyme. It was found that 4-fluorophenylimino substituent at 2- position and 3-nitro moiety on a 5-benzylidene nucleus of the 4-thiazolidinone derivative fitted in the COX-2 binding pocket. The compounds exhibited remarkable activity in scavenging free radicals, as depicted by the DPPH assay method. The structure-activity relationship was also established in the present work with respect to the nature and position of the substituents. The active compounds were evaluated for drug-like nature under Lipinski’s rule of five, and the toxicity behaviour of active compounds was predicted using ADMETlab software. The compounds have the potential to target degenerative disorders associated with inflammation and the generation of free radicals.

Mechanistic Basis

Increasing evidence has demonstrated that heme oxygenase-1 (HO-1) is a key enzyme triggered by cellular stress, exhibiting cytoprotective, antioxidant, and anti-inflammatory abilities. Previously, we prepared a series of novel active halophenols possessing strong antioxidant activities in vitro and in vivo. In the present study, we demonstrated that these halophenols exhibited significant protective effects against H2O2-induced injury in EA.hy926 cells by inhibition of apoptosis and ROS and TNF-αproduction, as well as induction of the upregulation of HO-1, the magnitude of which correlated with their cytoprotective actions. Further experiments which aimed to determine the mechanistic basis of these actions indicated that the halophenols induced the activation of Nrf2, Erk1/2, and PI3K/Akt without obvious effects on the phosphorylation of p38, JNK, or the expression of PKC-δ. This was validated with the use of PD98059 and Wortmannin, specific inhibitors of Erk1/2 and PI3K, respectively. Overall, our study is the first to demonstrate that the cytoprotective actions of halophenols involve their antiapoptotic, antioxidant, and anti-inflammatory abilities, which are mediated by the upregulation of Nrf2-dependent HO-1 expression and reductions in ROS and TNF-αgeneration via the activation of Erk1/2 and PI3K/Akt in EA.hy926 cells. HO-1 may thus be an important potential target for further research into the cytoprotective actions of halophenols.

Abstract Oxidative stress is a critical etiologic factor and driver of inflammatory responses, witnessed in chronic and persistent conditions. The current anti-oxidative stress and anti-inflammatory drugs are associated with detrimental effects, high dependence, high costs, inaccessibility, among other drawbacks; therefore, a need for alternatives is imperative. Despite the remarkable potential of medicinal plants, there are scanty empirical studies on their pharmacologic efficacy. The Phytexponent is an alcoholic polyherbal preparation of Allium sativum, Triticum repens, Echinacea purpurea, Viola tricolor and Matricaria chamomilla. In complementary medicine, the Phytexponent is used to boost immunity, to treat inflammatory disorders, oxidative stress, blood pressure, diabetes, stress/depression, among other conditions. However, there is no sufficient scientific data to support these healing claims. Therefore, in the current study evaluated the in vitro anti-inflammatory, antioxidant activities and qualitative phytochemical composition of the Phytexponent. The in vitro anti-inflammatory activities were evaluated using the inhibition of protein denaturation and the human erythrocyte (HRBC) membrane stabilization techniques. Antioxidant activities were evaluated by the 1,1-diphenyl-picryl-1-hydrazyl (DPPH) radical scavenging-, the hydroxyl radical scavenging- and catalase activities. Qualitative phytochemical screening was performed using standard procedures. The results showed a significantly higher percentage inhibition of heat-induced- and hypotonicity induced HRBC hemolysis by the Phytexponent at concentrations of 50 % and 100 %, compared with the percentage inhibitions of etanercept (p<0.05). No significant differences in percentage inhibitions of protein denaturation were observed among concentrations of 12.5 %,25.0 %,50.0 %,100.0 % of the Phytexponent and etanercept (25 mg/ml) (p˃0.05). Furthermore, the Phytexponent demonstrated high antioxidant activities against the DPPH- (IC50=0.00733%) and the hydroxyl- (IC50 = 0.716 %) radicals in vitro.The Phytexponent recorded significantly higher catalase activities at concentrations of 1 % and 0.1 % than those recorded by ascorbic acid at similar concentrations. Qualitative phytochemical screening revealed the presence of phenols, flavonoids, tannins, among other antioxidant associated phytochemicals. The bioactivities of the Phytexponent reported herein, were attributed to the presence of these phytochemicals. Further studies to establish specific mode(s) through which the Phytexponent exerts in vitro anti-inflammatory and antioxidant effects are encouraged. Moreover, in vivo anti-inflammatory and antioxidant activities should be done to determine the replicability of these findings in vivo. Bioassay-guided isolation of compounds responsible for the reported bioactivities herein should be done.

The chemical machinery of vegetables offers a great diversity of biological properties and plays a fundamental role in the field of pharmacology. The search for new drugs with fewer adverse effects represents a challenge for researchers. The objective of the present work was to carry out to investigate the medicinal properties and safety of extracts and essential oil from aerial parts of Clinopodium gilliesii (muña muña) and evaluate their antioxidant and anti-inflammatory activities in vivo. The extractions were carried out serially, using 96º alcohol (EE) and boiled distilled water (AE). The essential oil (EO) was obtained by steam dragging. The AE in vivo anti-inflammatory activity was determined by carrageenan induced plantar edema (acute inflammation) and granuloma formation by cotton disc (chronic inflammation) at oral doses of 250 and 500 mg/kg while that of the EO was established topically at doses of 50, 100μl/kg. In-vitro antioxidant activity was evaluated by DPPH depuration and inhibition of lipid peroxidation (β-carotene-linoleic acid method). Chemical study of the extracts was carried out by means of phytochemical screening and the essential oil was analyzed by GC-MS chromatography. The safety was evaluated with test of acute toxicity (48 h) and acute dermal toxicity (14 days). The results revealed that EE and EO had a significant acute and chronic anti-inflammatory activity, compared with positive patterns. EE (500 mg/kg), EO (100μl/kg), ibuprofen (100 mg/kg) and meprednisone (5 mg/kg) significantly reduced the weight of the exudate and cotton disc granuloma (24.17, 35.30, 45.56 and 57.17% respectively). The alcoholic and aqueous extracts presented important antioxidant activities with values higher than 90% (from 400μg/ml) in both methods and similar to the positive patterns (BHT and quercetin). The chromatographic profile of volatile oil compounds showed a great richness in terpene substances, pulegone, menthone and neomenthol, being its major constituents. The hydroalcoholic extracts revealed the presence of reducing compounds, polysaccharides, tannins, triterpenes, sterols and coumarins as major phytoconstituents. In the acute toxicity study, a single dose of 4000 and 8000 mg/kg b.w., produced no mortality and no clinical signs of disease were observed after 48 h. The essential oil at a single dose of 2000 and 5000 mg/kg of body weight did not produce treatment-related signs of toxicity or mortality in all rats tested during the 14 day observation period. These findings are encouraging to continue studies for the validation of popular use and development of a phytopharmaceutical with medicinal utility.
