Malaria is a life-threatening parasitic disease transmitted by the infected female Anopheles mosquito. The development of drug tolerance and challenges related to the drugs’ pharmacodynamic and pharmacokinetic parameters limits the antimalarial therapeutics response. Currently, nanotechnology-based drug delivery system provides an integrative platform for antimalarial therapy by improving the drug physicochemical properties, combating multidrug resistance, and lowering antimalarial drug-related toxicity. In addition, surface engineered nanocarrier systems offer a variety of alternatives for site-specific/targeted delivery of antimalarial therapeutics, anticipating better clinical outcomes at low drug concentrations and low toxicity profiles, as well as reducing the likelihood of the emergence of drug resistance. So, constructing nano carrier-based approaches for drug delivery has been considered the foremost strategy to combat malaria. This review focuses on the numerous nanotherapeutic strategies utilised to treat malaria as well as the benefits of nanotechnology as a potentially effective therapeutic.
Abstract Rising antibiotic resistance among periodontal pathogens poses a major challenge to treatment outcomes. This work investigates the possible combinatorial potential of AgNPs synthesized using glycyrrhizin, a natural biosurfactant, to combat biofilm‐forming bacteria isolated from periodontitis patients. In silico findings revealed that glycyrrhizin had a higher binding affinity score of ‐9.102 compared to doxycycline (−3.599) for the gtfB , plays an indispensable function in biofilm integrity. AgNPs were synthesized using glycyrrhizin and optimized utilizing the design of experiments, considering factors such as pH, temperature, incubation time and glycyrrhizin concentration as variables. while The resulting GL‐AgNPs were characterized by different analytical techniques such as FTIR, XRD, DLS, and SEM. The nanoparticles were non‐spherical, uniform and had an average size of 72 nm, while zeta potentials ranged from −28 mV to − 42 mV. Antimicrobial findings suggested that GL‐AgNPs exhibited significant antibacterial and anti‐biofilm activity compared to AgNPs prepared using sodium borohydride ( p < 0.001). Experimental findings suggested that GL‐AgNPs inhibited biofilm formation by attenuating Gtfase activity. Further, GL‐AgNPs show effective anti‐inflammatory activity with minimal cytotoxicity. Overall, this study highlights that the inherent antimicrobial and surfactant properties of glycyrrhizin greatly improve the antimicrobial potential of AgNPs, providing a promising approach to combating biofilm‐producing oral pathogens in periodontitis.
Diuretics are widely used in current clinical practice to increase urine production and excrete electrolytes, particularly sodium and chloride ions, without affecting the absorption of protein, vitamins, carbohydrates, or amino acids. From the time of mercury chloride and organomercurials in ancient times to now (with sulphonamides, thiazides, and furosemide), a lot has changed in the field of diuretics. However, long-term use of such synthetic diuretic agents in clinical practice produces several adverse effects, such as blurred vision, loss of appetite, stomach upset, carcinomas, headaches, phototoxic impact, weakness., etc., as has been observed from recent investigations. Natural regimens can serve as potential alternatives to using nontoxic diuretic agents. Based on long-term ethnomedicinal and biological activity records, we have explored the diuretic effects of the widely known perennial herb in Pacific Islands regions and a weed in agricultural fields, Eleusine indica (L) Gaertn phytoconstituents, on a computation platform. Therefore, we conducted a bio-assay-guided crude extraction using ethanol, followed by further gas chromatography-mass spectrometry (GC-MS) analyses of the extracted crude extracts. Further selected nine constituents (EI_1 to EI_9) carried out the diuretic potency against three putative target enzymes (ACE, KCNJ1, and SLC12A1) along with three standard drugs (VU590, TSM, and FSM) through molecular docking studies using AutoDock 4.2 software. We also predict physicochemical profiles, or Lipinski Rule of Five profiles, toxicity, and pharmacokinetics using various bioinformatics and cheminformatics tools. Based on the overall investigation, it was revealed that EI_6 [Z, Z-6,28-Heptatriacontadien-2-one] was the most potential, nontoxic, and drug-able candidate. In summary, advanced computational tools play a crucial role in selecting potential preclinical candidates within limited resources to accelerate the current drug discovery process.
<em>Citrus limetta </em>Risso (Rutaceae), commonly known as sweet lime in English and <em>Mousambi</em> in India, has been traditionally used for several medicinal purposes. This study explored the relationship between <em>Citrus limetta </em>fruit peel and its antitumor activity against Ehrlich ascites carcinoma (EAC) bearing mice. The antitumor activity of methanol extract of peel of <em>Citrus limetta</em> fruits (MECL) was evaluated against EAC cell line in Swiss albino mice. Twenty-four hours after intraperitoneal inoculation of tumor EAC cells in mice, MECL was administered at 200 and 400 mg/kg body weight i.p. daily for nine consecutive days. On the 10th day, half of the mice were sacrificed for the estimation of tumor growth (tumor volume, viable and non-viable tumor cell counts), and hematologic parameters (red blood cells, white blood cells and hemoglobin). The rest were kept alive for assessment of survival parameters, <em>i.e. </em>median survival time and percentage increase in life span of EAC bearing mice. Intraperitoneal administration of MECL at the doses of 200 and 400 mg/kg for nine days to the carcinoma induced mice demonstrated a significant (P<0.001) decrease in tumor volume, viable tumor cell count, tumor weight and a significant (P<0.001) improvement in hematological parameters and life span as compared to the EAC control mice. The present study establishes marked and dose dependant anti-tumor effect of <em>C. limetta </em>fruit peel against Ehrlich ascites carcinoma bearing Swiss mice.
