Abstract
Calotropis procera is a perennial flowering plant of the Apocynaceae family, traditionally used in medicine to treat various ailments. Recent investigations have revealed its potential therapeutic activities such as anti-inflammatory, gastroprotective, analgesic, anti-obesity, and anti-diabetic properties. RP-HPLC qualitatively and quantitatively evaluated the phenolic acids and flavonoids in the ethanolic extract at two different wavelengths, 280 and 330 nm. In addition, total phenolic and flavonoid contents were measured via spectrophotometric determination in addition to the antioxidant activity. The antiproliferative effects of C. procera were investigated on two cancer cell lines: human colon (HCT-116) and breast (MCF-7) cancer. Several methods were utilised to analyse the effectiveness of the plant extract on the cytotoxicity, apoptosis, cell cycle progression, genes involved in the cell cycle, and protein expression profiles of HCT-116 and MCF-7 cells. These included the MTT assay, Annexin V-FITC/PI, analysis of the cell cycle, and Western blot. Results indicated that ferulic and caffeic acids were the major compounds at λmax 280 nm (1.374% and 0.561%, respectively), while the major compounds at λmax 325 nm were kaempferol and luteolin (1.036% and 0.512%, respectively). The ethanolic extract had significantly higher antioxidant activity (80 ± 2.3%) compared to ascorbic acid (90 ± 3.1%). C. procera extract exhibited dose-dependent cell growth inhibition, with an estimated IC50 of 50 μg/mL for MCF-7 and 55 μg/mL for HCT-116 cells at 24 h. Annexin V-FITC/PI confirmed the induction of apoptosis. Remarkably, cell cycle arrest occurred at the sub-G1 phase in MCF-7 cells, while in HCT-116 cells, it was observed at the G2-M phase. The sub-G1 arrest was associated with dysregulation of Akt, p-AKT, mTOR, and p-mTOR proteins, as confirmed by the Western blot analysis, while downregulation of CDK1, cyclin B1, and survivin caused G2-M arrest.

Abstract
The study aimed to investigate the constituents of the ethanolic extract of Micromeria fruticosa and evaluate its antimicrobial and burn healing activities and the isolated compound, rutin. The plant was extracted with ethanol and the active constituents were isolated. The antimicrobial activities of the extract and the isolated compounds were assessed. The burn healing potentiality was evaluated in a second-degree burn model on rats. Five compounds were isolated and identified namely, oleanolic acid 3-O-β-D-glucopyranoside, apigenin, tectochrysin, 7,4' dihydroxyflavone7-rhamnoglucoside, and rutin. Noticeable antimicrobial activities of the extract, fractions and rutin, were obtained. These effects could be attributed to the isolated flavonoids and triterpenes compounds. The topical application of the extract or rutin significantly reduced the wound size and improved the skin histology. The molecular docking simulations predicted potential inhibitory interaction between rutin and the active site of IKKβ that could be responsible for blocking NF-κB activation; this could explain the possible mechanism by which rutin enhances the burn wounds healing process. Ethanolic extract, fractions and isolated compound, rutin of M. fruticosa exhibited significant antimicrobial activities. The plant extract and rutin demonstrated high potentialities to heal burns.

Abstract
Glucosinolate-producing plants have long been recognized for both their distinctive benefits to human nutrition and their resistance traits against pathogens and herbivores. Despite the accumulation of glucosinolates (GLS) in plants is associated with their resistance to various biotic and abiotic stresses, the defensive and biological activities of GLS are commonly conveyed by their metabolic products. In view of this, metabolism is considered the driving factor upon the interactions of GLS-producing plants with other organisms, also influenced by plant and plant attacking or digesting organism characteristics. Several microbial pathogens and insects have evolved the capacity to detoxify GLS-hydrolysis products or inhibit their formation via different means, highlighting the relevance of their metabolic abilities for the plants' defense system activation and target organism detoxification. Strikingly, some bacteria, fungi and insects can likewise produce their own myrosinase (MYR)-like enzymes in one of the most important adaptation strategies against the GLS-MYR plant defense system. Knowledge of GLS metabolic pathways in herbivores and pathogens can impact plant protection efforts and may be harnessed upon for genetically modified plants that are more resistant to predators. In humans, the interest in the implementation of GLS in diets for the prevention of chronic diseases has grown substantially. However, the efficiency of such approaches is dependent on GLS bioavailability and metabolism, which largely involves the human gut microbiome. Among GLS-hydrolytic products, isothiocyanates (ITC) have shown exceptional properties as chemical plant defense agents against herbivores and pathogens, along with their health-promoting benefits in humans, at least if consumed in reasonable amounts. Deciphering GLS metabolic pathways provides critical information for catalyzing all types of GLS towards the generation of ITCs as the biologically most active metabolites. This review provides an overview on contrasting metabolic pathways in plants, bacteria, fungi, insects and humans towards GLS activation or detoxification. Further, suggestions for the preparation of GLS containing plants with improved health benefits are presented.

Abstract
Background:
Cancer is one of the major causes of the death and affects people of all
ages throughout the world. The drugs that are currently available to treat cancer have many side
effects. Hence, there is considerable scientific interest in the continuing discovery of new
anticancer agents from natural sources. The aim of this study was to prepare and characterize
nanoparticles combining Indigofera intricata crude alcoholic extract and chitosan and to evaluate
the anticancer cell proliferative activity for both extract and nanoparticles.
Methods:
Dried alcoholic extract was prepared and characterized for its phenolic and flavonoid
contents. Chitosan extract nanoparticles was prepared by ionic gelation method and characterized
by thin layer chromatography (TLC), Fourier-transform infrared spectroscopy (FTIR), particle
size and zeta-potential analysis. The anticancer cell proliferative activities of both plant extract
and nanoparticles at different concentrations were evaluated using breast cancer cell line (MCF 7).
Results:
The alcoholic extract showed high contents from both phenolic and flavonoid constituents
(15 % and 22 % respectively). The interaction of polyphenolic compounds of the extract with
chitosan was confirmed by the TLC and FTIR results. The particle size and zeta-potential of
nanoparticles found to be 400.6nm ± 101.8 nm and +42.1 mV ± 9.27 mV respectively. The plant
extract showed the lowest cell viability of 45.21% ± 4.8% at the highest dose (250 mg) tested in
this investigation. Almost 500-fold reduction (from 250 mg to 0.5 mg) in the extract concentration
required to achieve same anticancer cell proliferative activity when formulated as nanoparticles.
Also 2.5 mg extract containing nanoparticles showed similar anticancer cell proliferative activity
as 5 mg 5-FU.
Conclusion:
Our results revealed that traditional medicinal plants could be an excellent source of
natural anticancer agents and the chitosan-extract nanoparticles is a promising formulation strategy
to enhance their clinical effectiveness.

Abstract
BACKGROUND Hyperurecemia is usually associated with gout and various metabolic arthritis disorders. Limited medications are available to manage such conditions. This study aimed to isolate the triterpenes constituent of the plant and to assess xanthine oxidase (XO) inhibitory and antihyperuricemic activities of Tribulus arabicus ethanolic extract, its fractions and the isolated compound using in vitro and in vivo approaches. METHODS The ethanolic extract, fractions; n-hexane, chloroform and n-butanol and the isolated compound (ursolic acid) were evaluated in vitro for their XO inhibitory activity. Those that demonstrated significant activity were further evaluated for their antihyperuricemic activity on potassium oxonate-induced hyperuricemia in mice. RESULTS The ethanolic extract was found to be safe up to 5000 mg/kg. The extract and its n-hexane fraction exhibited significant inhibitory activity on XO, whilst only a modest reduction in the enzymatic activity was noticed with n-butanol and chloroform fractions. Furthermore, administration of the ethanolic extract at low and high doses significantly reduced serum urate levels in mice by 31.1 and 64.6% respectively. The isolated active constituent, ursolic acid, showed potent XO inhibition activity (Half maximal inhibitory concentration, IC50 = 10.3 μg/mL), and significantly reduced uric acid level in vivo by 79.9%. Virtually, the binding mode of ursolic acid with XO was determined using molecular docking simulations. CONCLUSIONS The activity of the ethanolic extract of T. arabicus and its n-hexane fraction can be attributed to the isolated compound, ursolic acid. Ursolic acid has good hypouricemic activity and therefore has high potential to be used for the treatment of gout and hyperuricemia-related diseases.
