A metagenomic library consisting of 15,000 clones was constructed from the mangrove sediment. An antimicrobially active clone from the metagenomic library PS49 was identified by function- based screening. This paper presents the results of the biochemical characterization and metagenomic library screening of the marine-derived antibiotic, 8-demethoxy-10-deoxysteffimycin. Plasmid libraries were constructed, and clones were produced using a metagenomic approach. Out of 15,000 clones, 81 clones were screened for antimicrobial activity, and five potential clones were selected. The activity of one clone was characterized and named as PS49. The bioactive compounds from the selected clone were checked for antimicrobial, antioxidant, and anticancer activities. The clone PS49 was tested against various pathogens including bacteria and fungi and it showed inhibitory effects against all the tested pathogens. The antimicrobially active fractions were then crystallized and subjected to spectroscopic analysis such as FTIR, NMR and LC–MS analysis. The substance from clone PS49 has finally been recognized, and the compound from clone PS49 has been identified as 8-demethoxy-10-deoxysteffimycin. The substances isolated from the PS49 clone exhibited strong anticancer activity against skin cancer-cell lines SK-MEL2. The compounds showed a reduction in cell viability with an increase in the compound concentration. The compounds obtained from clone PS49 showed an IC50 value of 85 µg/ml. [ABSTRACT FROM AUTHOR]

Wound infections resulting from pathogen infiltration pose a significant challenge in healthcare settings and everyday life. When the skin barrier is compromised due to injuries, surgeries, or chronic conditions, pathogens such as bacteria, fungi, and viruses can enter the body, leading to infections. These infections can range from mild to severe, causing discomfort, delayed healing, and, in some cases, life-threatening complications. Zinc oxide (ZnO) nanoparticles (NPs) have been widely recognized for their antimicrobial and wound healing properties, while cinnamic acid is known for its antioxidant and anti-inflammatory activities. Based on these properties, the combination of ZnO NPs with cinnamic acid (CA) was hypothesized to have enhanced efficacy in addressing wound infections and promoting healing. This study aimed to synthesize and evaluate the potential of ZnO-CN NPs as a multifunctional agent for wound treatment. ZnO-CN NPs were synthesized and characterized using key techniques to confirm their structure and composition. The antioxidant and anti-inflammatory potential of ZnO-CN NPs was evaluated through standard in vitro assays, demonstrating strong free radical scavenging and inhibition of protein denaturation. The antimicrobial activity of the nanoparticles was tested against common wound pathogens, revealing effective inhibition at a minimal concentration. A zebrafish wound healing model was employed to assess both the safety and therapeutic efficacy of the nanoparticles, showing no toxicity at tested concentrations and facilitating faster wound closure. Additionally, pro-inflammatory cytokine gene expression was analyzed to understand the role of ZnO-CN NPs in wound healing mechanisms. In conclusion, ZnO-CN NPs demonstrate potent antioxidant, anti-inflammatory, and antimicrobial properties, making them promising candidates for wound treatment. Given their multifunctional properties and non-toxicity at tested concentrations, ZnO-CN NPs hold significant potential as a therapeutic agent for clinical wound management, warranting further investigation in human models.

Earthworms have a complex digestive system consisting of the mouth, pharynx, esophagus, crop, gizzard, and intestine which work together to pass the soil out. The gut soil and associated microbial load in earthworms' gut hinder the outcome of many experiments like in-vitro regeneration, histology, immunohistochemistry, molecular expression and toxicological studies. Currently, the available gut cleaning techniques are time-consuming and costly. The tissue paper method takes 4-7 days; the agar-agar method takes around 3-5 days to clean the gut. Therefore, refined techniques are needed to reduce the gut cleaning process in a cost-effective and at the same time in a minimum number of days. Bisacodyl is a medication used to treat constipation and it acts as a laxative drug that increases peristatic movement of the gut. It can also be used to cleanse the intestines before a bowel examination or surgery. The present study aims to enhance the gut-cleaning process in earthworm, Eudrilus eugeniae , using the drug bisacodyl. Briefly, the earthworm is exposed to different concentrations (1 mg, 2 mg, 4 mg, 6 mg, 8 mg and 10 mg) of bisacodyl and analyzed for its excretion rate. We observed that 4 mg is more efficient and aids in cleaning the earthworm's gut within two days. A lower bisacodyl concentration is inefficient in cleaning the gut in a shorter duration while at higher bisacodyl concentrations, worm experienced autotomy. Since the drug was active for only 45 mins, the worm became normal one hour after withdrawal from the experiment. Other than E. eugeniae , for Perionyx excavatus we observed 4 mg bisacodyl drug is efficient and aids in cleaning its gut within two days. Overall, the designed protocol is efficient for gut cleaning in a shorter duration in a cost-effective manner. [ABSTRACT FROM AUTHOR]

Background: Dental pathogens play a crucial role in oral health issues, including tooth decay, gum disease, and oral infections, and recent research suggests a link between these pathogens and oral cancer initiation and progression. Innovative therapeutic approaches are needed due to antibiotic resistance concerns and treatment limitations. Methods: We synthesized and analyzed piperine-coated zinc oxide nanoparticles (ZnO-PIP NPs) using UV spectroscopy, SEM, XRD, FTIR, and EDAX. Antioxidant and antimicrobial effectiveness were evaluated through DPPH, ABTS, and MIC assays, while the anticancer properties were assessed on KB oral squamous carcinoma cells. Results: ZnO-PIP NPs exhibited significant antioxidant activity and a MIC of 50 µg/mL against dental pathogens, indicating strong antimicrobial properties. Interaction analysis revealed high binding affinity with dental pathogens. ZnO-PIP NPs showed dose-dependent anticancer activity on KB cells, upregulating apoptotic genes BCL2, BAX, and P53. Conclusions: This approach offers a multifaceted solution to combatting both oral infections and cancer, showcasing their potential for significant advancement in oral healthcare. It is essential to acknowledge potential limitations and challenges associated with the use of ZnO NPs in clinical applications. These may include concerns regarding nanoparticle toxicity, biocompatibility, and long-term safety. Further research and rigorous testing are warranted to address these issues and ensure the safe and effective translation of ZnO-PIP NPs into clinical practice. [ABSTRACT FROM AUTHOR]

A robust strategy is imperative to counteract multi-resistant pathogens within the oral cavity and mitigate the occurrence of dental-related diseases. According to the recent Global Oral Health Status Report (2022), over 3.5 billion individuals worldwide have been affected, with more than 2 billion experiencing permanent tooth caries. Despite employing various techniques to combat oral pathogens, these microbes persistently proliferate, culminating in biofilm formation that exhibits resistance to conventional antibiotics. Moreover, there is a notable surge in the rate of implant failure attributable to peri-implantitis. Peptide therapy emerges as a promising and enduring solution, demonstrating adaptability to diverse techniques. The pivotal technique involving Antimicrobial peptides (AMPs) orchestrates damage to the extracellular matrix, encompassing the glucan matrix, disrupting microbial content, and inducing pathogen demise. Notably, AMPs actively participate in the intricate process of oral tissue healing. Nanofibers, characterized by their multifaceted properties and robust mechanical capacity, facilitate protracted drug delivery and manifest optimal biocompatibility. This inherent attribute stimulates the application of AMPs, thereby augmenting healing durations and ensuring sustained therapeutic efficacy against oral diseases. The primary focus of this review centers on Antimicrobial peptides (AMPs) integrated into Nanofibers, offering a comprehensive clinical solution to diverse dental-mediated diseases. The exploration of various AMPs and their modes of action, coupled with the efficacy of peptide durability, sets the stage for futuristic enhancements in oral health therapeutics.
