BACKGROUND: Oral cancer poses a significant threat to public health worldwide. In addition, because many chemotherapy treatments have negative side effects, natural herbs may be beneficial for oral cancer therapy. Achyranthes aspera (AA), a potential medicinal herb, exerts various pharmacological and biochemical activities.
OBJECTIVE: The present study aimed to predict the anti-oral cancer potential of AA using in silico tools and cell death by in vitro testing.
METHODS: A total of fourteen bioactive constituents from AA herb were selected using phytochemical databases. The toxicity of AA herb extract was analysed through MTT assay against oral carcinoma A253 cell line. The binding activities of the phytocomponents against serine/ threonine-specific protein kinases isoforms, namely Akt1 (PDB ID: 3qkk) and Akt2 (PDB ID: 2jdo) proteins, were analysed using Discovery Studio 2021 and PyRx docking software.
RESULTS: Cell viability data revealed that AA extract decreased the viability and reduced the number of live cells of the oral carcinoma A253 cell line in a dose-dependent manner. The halfmaximal concentration (IC50) value of AA was assessed as 204.74 μg/ml. Based on binding affinity, saponin C (-CDOCKER energy = -77.9862), oleanolic acid (-CDOCKER energy = - 49.4349), spinasterol (-CDOCKER energy = -38.1246), 36,47-dihydroxyhenpentacontan-4-one (-CDOCKER energy = -32.4386), and 20-hydroxyecdysone (-CDOCKER energy = -31.9138) were identified as the best compounds against Akt1, while, compounds saponin C (-CDOCKER energy = -134.412), oleanolic acid (-CDOCKER energy = -90.0846), spinasterol (-CDOCKER energy = -78.3213), 20-hydroxyecdysone (-CDOCKER energy = -80.1049), and ecdysone (- CDOCKER energy = -73.3885) were identified as Akt2 inhibitors. These top compounds fulfilled drug score values, pharmacokinetic and physicochemical characteristics, and druglikeness parameters.
CONCLUSIONS: The present findings reveal that the lead phytomolecules of AA could be effective and developed as a prospective drug against oral cancer.

BACKGROUND: Achyranthes aspera L. (family Amaranthaceae) is a plant species valued in Ayurveda for the treatment of respiratory ailments. Scientific validation of its antiallergic potential was aimed.
RESULTS: Three extracts of A. aspera [aqueous (AaAq), hydroalcoholic (AaHA), ethanolic (AaEt)] were evaluated for their potency against C48/80-induced anaphylaxis in mice at 200 mg/kg BW oral dose. The effective dose of the most potent extract was determined through its effect on C48/80-induced anaphylaxis, and was further analyzed through its effect on mast cell degranulation, histamine-induced bronchospasm and ovalbumin (OVA)-induced asthma in a murine model. Among the three extracts, AaAq was found to be most potent at 200 mg/kg BW. AaAq 400 (400 mg/kg BW) was found to be the most effective dose in terms of inhibition of mortality and histamine level. AaAq 400 prevented the peritoneal and mesenteric mast cells from undergoing morphological changes due to degranulation induced by C48/80. Further, AaAq 400 delayed pre-convulsive time in histamine-induced bronchospasm. In the OVA-induced asthma model, AaAq 400 inhibited the level of inflammatory cell count in blood, bronchoalveolar lavage fluid and peritoneal fluid of mice. The Th2 cytokines (IL-4, IL-5, IL-13), TGF-β and OVA-specific IgE were also reduced as evaluated by ELISA. Also, significant reduction in IL-5 (an eosinophilia indicator) transcript abundance and lung inflammatory score was observed. AaAq was safe up to 4000 mg/kg BW.
CONCLUSIONS: Thus AaAq 400 possesses significant antiallergic potential and acts via attenuation of C48/80-induced anaphylaxis and inhibition of mast cell degranulation. It reduces pre-convulsive dyspnea in histamine-induced bronchospasm and Th2 cytokines in asthmatic mice.

Schistosomiasis is a debilitating chronic disease with great socioeconomic and public health impact affecting the poor rural populations who lack access to sanitation, and safe water supply. The high cost of synthetic molluscicides, their toxicity to non-target organisms, and their persistence in the environment have forced the research of plant-derived molluscicides. Although plant molluscicides are cheap, biodegradable, ecofriendly and less toxic to higher animals, unregulated applications could affect non-target organisms. Therefore, ecotoxicological studies are essential to assess the toxicity of these substances to economically and ecologically significant fish species and to establish safe dosage level. This study is intended to investigate the acute toxicity of a molluscicidal plant Achyranthes aspera to Nile tilapia fingerlings, Oreochromis niloticus (O. niloticus) (n = 7) were exposed to serial dilutions of A. aspera leaf aqueous extract using maceration method for 96 h in triplicate setup. Phytoconstituents were identified by GC-MS. Mortality data were analyzed by probit regression to determine lethal concentrations. The NOAEC was ascertained through hypothesis testing based on survival data. The respective piscicidal LC1 and LC10 values were 897.43 and 1063.87 mg/L while the LC50 is 1310.74 mg/L. In addition, the NOAEC was 1100 mg/L (p > 0.05). This piscicidal toxicity is much lower than its molluscicidal potency may be due to the presence of rotenones and triterpenoides which are commonly found in piscicidal natural products. The GC-MS analysis revealed 12 phytoconstituents including a monoterpene. This study indicates that A. aspera has low toxicity to Nile tilapia could be due to monoterpenes are nontoxic. The findings of this study demonstrate that, at this dose, the plant is safe to the test fish. Thus it can be effective, eco-friendly and sustainable alternative for the development of molluscicides for snail control.

The genus Achyranthes belong to the family Amaranthaceae which constitutes an important group of herbs and shrubs with immense medicinal value. The present research work was conducted to investigate the anticancer potential of Achyranthes aspera L. leaves by focusing on the antioxidant, aniproliferative and antimitotic activities of leaf extracts. Plant extraction was carried out by soxhelt method with different solvents. Phytochemical characterization of the plants extracts using chemical methods identified the presence of cardiac glycosides, saponins, coumarins, proteins, tannins, flavonoids and triterpenes. Alkaloid was present in methanolic and ethanolic extract. High performance liquid chromatography showed presence of different concentration of myricetin, quercetin and kaempferol in different extracts with the highest concentration of myricetin (84.53 μg/mL) in n-butanolic extract. The extracts were then tested for antioxidant activity using 2,2-diphenylpicrylhydrazyl (DPPH) radical scavenging assay by spectrophotometric method. In DPPH radical scavenging assay, antioxidant activity of A. aspera ranged between 79.78 ± 0.034% and 58.63 ± 0.069%. Highest antioxidant activity was observed for methanolic extract and lowest for acetone. Antimitotic activity was determined by using Allium cepa assay in which microscopic investigation was carried out to observe normal and abnormal phases of mitosis. In this assay, n-butanolic extract had highest antimitotic activity with minimum mitotic index at 2 mg/mL (57 ± 0.0351%). The plant extracts also caused chromosomal and mitotic aberrations which were clearly observed under 40× and 100× magnification of compound microscope. Antiproliferative activity was determined by using yeast cell model in which light microscope with hemocytometer was used for cell counting. In case of Antiproliferative activity, the ethyl acetate extract of A. aspera had highest antiproliferative activity with lowest cell viability (22.14 ± 0.076%) at highest extract concentration (2 mg/mL) while methanol extract of A. aspera had highest antiproliferative activity with lower cell viability (24.24 ± 0.057%) at lowest extract concentration (0.25 mg/mL). The results of the study indicated that the leaves extract of A. aspera have strong potential to be used as a source of anti-cancer agent. RESEARCH HIGHLIGHTS: Achyranthes aspera L. leaves have various phytochemicals which contribute to its medicinal properties Various extracts of the leaves of A. aspera L. possess antioxidant, antimitotic and antiproliferative potential The results of the study indicated that the leaves extract of A. aspera have strong potential to be used as a source of anti-cancer agent.

This investigation was designed and performed to compare the phytochemical profiling, activities of antibacterial, thrombolytic, anti-inflammatory, and cytotoxicity of methanol extract (ME-E) and aqueous extract (AQ-E) of aerial parts of Achyranthes aspera through in-vitro approach. Also characterize the functional groups of bioactive compounds in the ME-E through Fourier-transform infrared (FTIR) spectroscopy analysis. Interestingly, qualitative phytochemical screening proved that the ME-E contain more number of vital phytochemicals such as phenolics. saponins, tannins, alkaloids, flavonoids, cardiac glycosides, steroids, and phlobatannins than AQ-E. Similarly, the ME-E showed notable antibacterial activity as dose dependent manner against Bacillus subtilis, Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, and Pseudomonas aeruginosa at 1000 μg mL-1 concentration. ME-E also showed 75.2 ± 2% of clot lysis (thrombolytic activity) at 1000 μg mL-1 dosage and it followed by AQ-E 51.24 ± 3%. The ME-E showed moderate and AQ-E demonstrate poor anti-inflammatory activity evidenced by albumin denaturation inhibition and anti-lipoxygenase assays. Furthermore, the ME-E demonstrated a dose dependent cytotoxicity was noted against brine shrimp larvae. In support of this ME-E considerable activities, the Fourier transform infrared (FTIR) analysis confirmed that this extract contain more number peaks attributed to the stretch of various essential functional groups belongs to different bioactive compounds. Hence this ME-E of A. aspera can be considered for further in depth scientific investigations to validate their maximum biomedical potential.

BACKGROUND: Achyranthes aspera, a widely recognized medicinal plant, is used in various cultures for treating different ailments, including renal dysfunction; however, there is a lack of comprehensive understanding of its protective effects and the underlying signaling networks involved.
OBJECTIVE: This study aimed to investigate the molecular mechanisms of the action of A. aspera by employing an integrative approach including functional and tissue imaging as well as comprehensive genomics analysis.
METHODS: Cisplatin-induced nephrotoxicity is a well-established animal model for acute kidney injury (AKI). In this study, we investigated the protective effects and underlying mechanisms of the action of A. aspera water-soluble extract (AAW) on a murine model of cisplatin-induced AKI. The evaluation includes measurements of blood urea nitrogen (BUN) and serum creatinine (SCr) levels, histology examination, and transcriptome analysis using RNA sequencing.
RESULTS: In male ICR mice, oral administration of AAW at doses of 0.5-1.0 g/kg significantly reduced cisplatin-induced nephrotoxicity. This effect included the amelioration of tubular injury, renal fibrosis, and the lowering of BUN and SCr levels. AAW also effectively decreased oxidative markers, such as malondialdehyde (MDA) and nitrotyrosine (NT), along with inflammation markers, including COX-2, iNOS, NLRP3, and pP65NFκB. Moreover, AAW administration induced a dose-dependent increase in the expression of two protective factors, Nrf2 and BcL2, and suppressed apoptosis, as evidenced by reduced levels of truncated caspase 3 (t-Casp3). To explore the underlying molecular mechanisms and signaling networks, next-generation sequencing (NGS) analysis was employed. The results revealed that AAW mitigated apoptosis, necroptosis, and PANoptosis pathways by inhibiting inflammation signaling pathways, such as the TNFα-, NFκB-, NETs-, and leukocyte transendothelial migration pathways. Additionally, AAW was found to enhance protective signaling pathways, including the cGMP/PKG-, cAMP-, AMPK-, and mTOR-dependent activation of autophagy and mitophagy pathways. The primary bioactive compound found in AAW was identified as 20-hydroxyecdysone (0.36%).
CONCLUSIONS: Our study demonstrates that AAW reduces cisplatin-induced nephrotoxicity. The protective effects of AAW are attributed to its modulation of multiple molecular signaling networks. Specifically, AAW downregulates genes and signaling pathways associated with oxidative stress and endoplasmic reticulum (ER) stress, inflammation, and PANoptosis. Simultaneously, it upregulates genes and signaling pathways associated with cell survival, including autophagy and mitophagy pathways.

A chemical study of the methanol extract of the aerial parts of Achyranthes aspera led to the isolation of four new flavonoid C-glycosides (1-4) along with eight known analogs (5-12). Their structures were elucidated by a combination of spectroscopic data analysis, HR-ESI-MS, 1D and 2D NMR spectra. All the isolates were evaluated their NO production inhibitory activity in LPS-activated RAW264.7 cells. Compounds 2, 4, and 8-11 showed significant inhibition with IC50 values ranging from 25.06 to 45.25 μM, compared to that of the positive control compound, L-NMMA, IC50 value of 32.24 μM, whereas the remaining compounds were weak inhibitory activity with IC50 values over 100 μM. This is the first report of 7 from Amaranthaceae family, and 11 from the genus Achyranthes.

Aedes aegypti is responsible for the global spread of several ailments such as chikungunya, dengue, yellow fever, and Zika. The use of synthetic chemicals is the primary intervention in mosquito management. However, their excessive utilization resulting in the spread of toxic ingredients in the environment and posing threats to beneficial organisms has prompted the recommendation for the use of biologically synthesized nanocomposites as a promising approach for vector control. Silver nanocomposites were synthesized using leaf (AL-AgNCs) and stem (AS-AgNCs) extracts of Achyranthes aspera. The early fourth instars of A. aegypti were exposed to lethal doses of these nanocomposites to evaluate their effects on larval development, behavior, morphology, and mid-gut histoarchitecture. The cellular damage and deposition of nanocomposite residues in the mid-gut were studied using light and transmission electron microscopy. The A. aspera silver nanocomposite (AA-AgNC)-exposed larvae exhibited dose-dependent extended duration of development and diminished adult emergence, but did not exhibit modified behavior. Intense damage to the cuticle membrane and slight contraction in the internal membrane of anal papillae were noticed. Morphologically, the mid-gut appeared disorganized, darkly pigmented, and shrunk. Histological investigations of the mid-gut revealed significantly disordered internal architecture with lysed cells, damaged peritrophic membrane and microvilli, disintegrated epithelial layer, and a ruptured and displaced basement membrane. Visualization of the larval mid-gut through TEM showed severe cellular damage and aggregation of black spots, indicating the deposition of silver particles released by AA-AgNCs. The investigations revealed the bio-efficacy of A. aspera-mediated AgNCs against A. aegypti inducing stomach and contact toxicity in the larvae. The utilization of AA-AgNCs is recommended for A. aegypti management as a safe and effective intervention.
