Abstract
The current study aimed to find out the anti-arthritic activity and safety study of Coronopus didymus aqueous extract (CDAE) as well as its chemical characterization by HPLC-DAD. Safety study including acute and subacute toxicity studies of the plant aqueous extract was also performed. In complete Freund's adjuvant-induced arthritic model (CFA), 0.15 ml CFA was injected in the left hind paw at day 1 in all rats except normal rats. Treatment with CDAE at 200, 400, and 800 mg/kg and methotrexate (1 mg/kg) was administered at day 8 and continued till 28th day using oral gavage. The CDAE considerably (p < 0.05) reduced the paw swelling and arthritic score, and reinstated the body weight and blood parameters. The CDAE considerably modulated superoxide dismutase, catalase, reduced glutathione, and malondialdehyde level in liver homogenate in contrast to disease control. The CDAE at 400 mg/kg considerably reduced IL-6, IL -1β, COX-2, and NF-ĸβ, whereas elevated IL-10, IL-4, and I-kappa β as equated to disease and standard groups. The LD50 of CDAE > 2000 mg/kg. In subacute toxicity study, CDAE at 200-800 mg/kg did not exhibit clinical signs of toxicity, mortality, hematological, biochemical, and histological alteration in the liver heart, kidney, and lungs in contrast to the normal group. It was concluded that the presence of delphinidine-3-glucoside, diosmetin, 3-feruloyl-4,5-dicaffeoyl quinic acid, and gallic acid in CDAE might be accountable for its anti-arthritic activity and safe use for a long period.

Polyphenolic Composition, Antioxidant, Antiproliferative and Antidiabetic Activities of Coronopus didymus Leaf Extracts. Molecules 2022; 27:molecules27196263. [PMID: 36234800 PMCID: PMC9570767 DOI: 10.3390/molecules27196263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 09/06/2022] [Accepted: 09/20/2022] [Indexed: 12/03/2022] Open
Abstract
Coronopus didymus (Brassicaceae) commonly known as lesser swine cress has been reported to be used for its pharmacological activities. This study aimed to evaluate the medicinal potential of C. didymus extracts against cancer, diabetes, infectious bacteria and oxidative stress and the identification of bioactive compounds present in these extracts. The effects of using different solvents for the extraction of C. didymus on the contents of major polyphenols and biological activities were investigated. Plant sample was shade dried, ground to a fine powder, and then soaked in pure acetone, ethanol and methanol. The highest contents of major polyphenols were found in methanol-based extract, i.e., chlorogenic acid, HB acid, kaempferol, ferulic acid, quercetin and benzoic acid with 305.02, 12.42, 11.5, 23.33, 975.7 and 428 mg/g of dry weight, respectively, followed by ethanol- and acetone-based extracts. The methanol-based extract also resulted in the highest antioxidant activities (56.76%), whereas the highest antiproliferative (76.36) and alpha glucosidase inhabitation (96.65) were demonstrated in ethanol-based extracts. No antibacterial property of C. didymus was observed against all the tested strains of bacteria. Further studies should be focused on the identification of specific bioactive compounds responsible for pharmacological activities.

Abstract
Polyphenolic compounds have a variety of functions in plants including protecting them from a range of abiotic and biotic stresses such as pathogenic infections, ionising radiation and as signalling molecules. They are common constituents of human and animal diets, undergoing extensive metabolism by gut microbiota in many cases prior to entering circulation. They are linked to a range of positive health effects, including anti-oxidant, anti-inflammatory, antibiotic and disease-specific activities but the relationships between polyphenol bio-transformation products and their interactions in vivo are less well understood. Here we review the state of knowledge in this area, specifically what happens to dietary polyphenols after ingestion and how this is linked to health effects in humans and animals; paying particular attention to farm animals and pigs. We focus on the chemical transformation of polyphenols after ingestion, through microbial transformation, conjugation, absorption, entry into circulation and uptake by cells and tissues, focusing on recent findings in relation to bone. We review what is known about how these processes affect polyphenol bioactivity, highlighting gaps in knowledge. The implications of extending the use of polyphenols to treat specific pathogenic infections and other illnesses is explored.

Abstract
Coronopus didymus (L.) Sm. (CD) has been traditionally used to treat pain, rheumatism, and inflammation. This study was planned to appraise the anti-oxidant, anti-inflammatory and anti-arthritic potentials of CD (whole plant) aqueous ethanolic (CDAEE) and aqueous extracts (CDAE) and chemical characterization by high-performance liquid chromatography-diode array detector. In vivo anti-inflammatory (Carrageenan induced paw edema, and Xylene induced ear edema assays) and anti-arthritic potentials were evaluated in Wistar rats. Both extracts showed significant (p < 0.0001) in vitro free radical scavenging and in vitro anti-arthritic potentials by inhibition of protein denaturation and stabilization of the HRBC membrane and anti-oedematogenic potential, whereas more activity was expressed by CDAEE. In complete Freund's adjuvant-induced arthritic model, the CDAEE at 200, 400, and 800 mg kg-1 and methotrexate (1 mg kg-1) profoundly (p < 0.05) reduced the arthritic score and paw edema, restored body and immune organ weight, and altered blood parameters and oxidative stress biomarkers. The qRT-PCR analysis revealed that CDAEE at 400 mg kg-1 significantly (p < 0.0001) downregulated TNF-α (2.22 ± 0.16 fold), IL-6 (2.29 ± 0.05 fold), IL-1β (2.10 ± 0.01 fold), COX-2 (2.45 ± 0.02 fold), and NF-ĸβ (2.72 ± 0.06 fold) and considerably upregulated IL-10 (58.84 ± 0.67%), IL-4 (76.16 ± 2.79%) and I-kβ (75.45 ± 0.17%) in arthritic rats in contrast to disease control and methotrexate as evidenced from the joint histology. These findings suggested the antioxidant, anti-inflammatory and anti-arthritic activities of C. didymus, which might be due to the presence of quercetin, ferulic acid, dihydromyricetin, apigenin, vitexin, and kaempferol in CDAEE.

Abstract
The thermal stability of purified acid phosphatase from the germinating seedlings of Coronopus didymus (Jangli halon) was investigated by studying the impact of various thermodynamic parameters [t1/2, Ed, ΔH° (enthalpy change), ΔG° (free energy change), and ΔS° (entropy change)] of heat treatment in the temperature range of 55-75 °C. The thermal denaturation of acid phosphatase, assessed by loss in activity, was evidently followed by first-order kinetics, which varies with time and yield during the process of denaturation. The half-life of the enzyme was 693 min at 55 °C. The Ed (activation energy of denaturation) was calculated by the Arrhenius plot (30 kcal mol-1), and the Z-value was 17.3 °C. The various thermodynamic parameters studied were as follows: ΔH°, the change in enthalpy of inactivation, was 121.93 kJ mol-1 at 55 °C; ΔG°, the change in free energy of inactivation, was 110.65 kJ mol-1 at 55 °C; and ΔS°, the change in entropy of inactivation, was 34.39 J mol-1 k-1 at 55 °C. This suggests that acid phosphatase activity is thermostable to long heat treatment up to 60 °C.

Abstract
BACKGROUND Besides the numerous biologic and pharmacologic functions in the human body that act as potent antioxidants, flavonoids (flavones, flavanones, flavonols, flavanols and isoflavones) are noted as cancer preventive or therapeutic agents. METHODS This review summarizes the published data using PubMed, Science Direct, and Scopus. RESULTS In this context, recognition and introduction of the most active cytotoxic flavonoids as promising agents for cancer therapy gives insight for further evaluations. However, there are some critical points that may affect the entering of flavonoids as active cytotoxic phytochemicals in the clinical phase. Issues such as the abundance of active species in nature, the methods of extraction and purification, solubility, pharmacokinetic profile, presence of the chiral moieties, method of synthesis, and structure modification may limit the entry of a selected compound for use in humans. Although plenty of basic evidence exists for cytotoxic/antitumor activity of the versatility of flavonoids for entry into clinical trials, the above-mentioned concerns must be considered. CONCLUSION This review is an effort to introduce cytotoxic natural flavonoids (IC50< 10 µM) that may have the potential to be used against various tumor cells. Also, active constituents, molecular mechanisms, and related clinical trials have been discussed as well as the limitations and challenges of using flavonoids in clinic.

Abstract
BACKGROUND Acetylcholinesterase (AChE), a serine hydrolase, is primarily responsible for the termination of signal transmission in the cholinergic system, owing to its outstanding hydrolyzing potential. Its substrate acetylcholine (ACh), is a neurotransmitter of the cholinergic system, with a predominant effect on motor neurons involved in memory formation. So, by decreasing the activity of this enzyme by employment of specific inhibitors, a number of motor neuron disorders such as myasthenia gravis, glaucoma, Lewy body dementia, and Alzheimer's disease, among others, can be treated. However, the current-available AChE inhibitors have several limitations in terms of efficacy, therapeutic range, and safety. SCOPE AND APPROACH Primarily due to the non-compliance of current therapies, new, effective and safe inhibitors are being searched for, especially those which act through multiple receptor sites, but do not elicit undesirable effects. In this regard, the evaluation of phytochemicals such as flavonoids, can be a rational approach. The therapeutic potential of flavonoids has already been recognized agaisnt several ailments. This review deals with various plant-derived flavonoids, their preclinical potential as AChE inhibitors, in established assays, possible mechanisms of action, and structural activity relationship (SAR). RESULTS AND CONCLUSIONS Subsequently, a number of plant-derived flavonoids with outstanding efficacy and potency as AChE inhibitors, the mechanistic, their safety profiles, and pharmacokinetic attributes have been discussed. Through derivatization of these reported flavonoids, some limitation in efficacy or pharmacokinetic parameters can be addressed. The selected flavonoids ought to be tested in clinical studies to discover new neuro-therapeutic candidates.

ASIAN PAC J TROP MED 2017; 10:792-801. [PMID: 28942828 DOI: 10.1016/j.apjtm.2017.07.024] [Citation(s) in RCA: 73] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2017] [Revised: 05/19/2017] [Accepted: 06/17/2017] [Indexed: 11/28/2022] Open
Abstract
OBJECTIVE To evaluate the total phenolic content and compare the antioxidant activity of various solvent extracts and fractions from the aerial parts of Coronopus didymus through various assays. METHODS Total phenolic content was determined using the Folin-Ciocalteu assay and the in vitro antioxidant activity of a number of different extracts was investigated in a dose-dependent manner with three different methods: the 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) and ferric reducing antioxidant power (FRAP) assays. A flavone was isolated from the most active ethanolic extract with high antioxidant activity using size exclusion chromatography. IC50 values were calculated for the DPPH and ABTS methods. The FRAP activity was assessed in terms of μM Fe (II) equivalent. RESULTS The phenolic content was found to be highest in the ethanol extract (CDA Et; 47.8 mM GAE) and the lowest in the dichloromethane extract (CDA DCM; 3.13 mM GAE). The ethanol extract showed high radical scavenging activity towards DPPH and ABTS radicals with IC50 values of (7.80 × 102) and (4.32 × 102) μg/mL, respectively. The most active ethanol extract had a FRAP value of 1921.7 μM Fe (II) equivalent. The isolated flavone F10C (5,7,4'-trihydroxy-3'-methoxy flavone) was far more effective for scavenging free radicals in the DPPH and ABTS assays with IC50 of 43.8 and 0.08 μg/mL, than the standard trolox, with IC50 values of 97.5 and 21.1 μg/mL, respectively. In addition, the flavone F10C and the standard ascorbic acid had FRAP values of 1621.7 and 16 038.0 μM Fe (II) equivalents, respectively. CONCLUSIONS The total phenolic content of extracts in decreasing order is ethanol extract (CDA Et) > acetone extract (CDA ACE) > phenolic extract (CDA MW) > n-hexane extract (CDA nHX)> chloroform extract (CDA CHL) > dichloromethane extract (CDA DCM). The ordering of extracts in terms of antioxidant activity from highest to lowest is CDA Et > CDA MW > CDA DCM > CDA CHL > CDA ACE > CDA nHX in DPPH, ABTS and FRAP assays. A significant relationship is found between antioxidant potential and total phenolic content, suggesting that phenolic compounds are the major contributors to the antioxidant activity of C. didymus.
