    Abstract Introduction: The Bruguiera cylindrica L. is a mangrove plant that is typically found in coastal areas of Asia, including India. It has been known for its medicinal properties, which have been utilized for generations. For example, in Thailand, it has been used to treat wounds and diarrhoea, while in India, it has been effective in addressing diabetes, ulcers, and other health issues. This particular study sought to investigate the potential of B. cylindrica bark extract in reducing the symptoms of diabetes in rats.
    Methods: In this study, we examined the potential of B. cylindrica bark extract as an inhibitor of α-amylase and α-glucosidase enzymes in vitro. We also evaluated the effects of the extract and Metformin on rats fed high-fat diets and measured their lipid profiles and biochemical parameters. Furthermore, we conducted a network pharmacology analysis to identify proteins and pathways involved in the amelioration of diabetes.
    Results: Through metabolite profiling, we identified 58 compounds in B. cylindrica hydroalcoholic extract. These compounds include alkaloids, phenolics, flavonoids, and fatty acids. The extract was found to have a dose-dependent inhibition activity against α-amylase and α-glucosidase, with IC50 values similar to acarbose. In rats, oral administration of 200-400 mg/kg of B. cylindrica led to reduced blood glucose levels and normalized serum biochemical parameters.
    Conclusions: Bruguiera cylindrica bark may reduce blood sugar levels in rats with diabetes. The study found metabolites that interact with protein targets associated with different types of diabetes.

    Abstract Trachyspermum ammi (L.) Sprague (Apiaceae), commonly known as "Ajwain" is distributed throughout India. Ajwain fruits contain fiber, carbohydrates, phenolic acids, flavonoids, and tannins. The fruits also yield a small amount of essential oil, with Thymol as the principal constituent. Ajwain has various pharmacological activities like anti-leishmanial, antimicrobial, cytotoxic, antispasmodic, nematocidal, and anthelmintic. The fruits are of high therapeutic value; thus, it becomes quite essential to evaluate the quality of Trachyspermum ammi (L.) Sprague to authenticate and ensure its therapeutic and nutritional properties. The ethyl acetate fraction of Trachyspermum ammi (L.) Sprague fruits exhibited the highest total phenolic and flavonoid content values of 149.55 ± 1.19 mg rutin equivalent and 682.85 ± 3.68 mg gallic acid equivalent, respectively. Metabolite profiling of the ethyl acetate fraction using ultra-performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry analysis resulted in identifying 19 phytomolecules. A validated high-performance thin-layer chromatography method was developed to quantify standard phytomolecules in the ethyl acetate fraction. The highest and lowest percentages of phytomarker were found to be caffeic acid (5.51% ± 0.16% w/w) and gallic acid (1.29% ± 0.09% w/w), respectively. This validated rapid, accurate, and precise method for standardization of Trachyspermum ammi (L.) Sprague will be beneficial for its quality evaluation as well as the derived products.

    Abstract The recent advancements of single-cell analysis have significantly enhanced the ability to understand cellular physiology when compared to bulk cellular analysis. Here a massively parallel single-cell patterning and very large biomolecular delivery is reported. Micro-pillar polydimethyl siloxane stamp with different diameters (40-100 µm with 1 cm × 1 cm patterning area) is fabricated and then imprint distinct proteins and finally pattern single-cell to small clusters of cells depending on the micro-pillar diameters. The maximum patterning efficiency is achieved 99.7% for SiHa, 96.75% for L929, and 98.6% for MG63 cells, for the 100 µm micro-pillar stamp. For intracellular delivery of biomolecules into the patterned cells, a titanium micro-dish device is aligned on top of the cells and exposed by infrared light pulses. The platform successfully delivers small to very large biomolecules such as PI dyes (668 Da), dextran 3000 Da, siRNA (20-24 bp), and large size enzymes (464 KDa) in SiHa, L929 and MG63 cells. The delivery efficiency for PI dye, Dextran 3000, siRNA, and enzyme for patterned cells are ≈95 ± 3%, 97 ± 1%, 96 ± 1% and 94 ± 3%, with cell viability of 98 ± 1%. Thus, the platform is compact, robust, easy for printing, and potentially applicable for single-cell therapy and diagnostics.

    Abstract Lung cancer remains a major public health concern among all cancer diseases due to the toxicity and side-effects of the available commercially synthesized drugs. Natural product-derived synthesized anticancer drugs are now of promising interest to fight against cancer death. Carvacrol is a major component of most essential oil-bearing plants with potential pharmacological activity, especially against various cancer cell lines. Among the other organometallic compounds, copper complexes have been reported to be effective anticancer agents against various cancer cell lines, especially lung and leukemia cancers, due to the nontoxic nature of copper in normal cells since it is an endogenic metal. In this study, we synthesized three carvacrol derivatives, i.e., carvacrol aldehyde, Schiff base, and copper-Schiff base complex, through an established synthesis protocol and characterized the synthesized product using various spectroscopic techniques. The synthesized derivatives were evaluated for in vitro cytotoxic activity against different cancer cell lines, including human lung cancer (A549) and human fibroblast (BALB-3T3). Our findings showed that the copper-Schiff base complex derived from carvacrol inhibited the proliferation and migration of the A549 cell lines in a dose-dependent manner. This activity might be due to the inhibition of cell proliferation and migration at the G

    Abstract Introduction: Black rice (Oryza sativa L.), which is rich in polyphenols and flavonoids, is indigenous to Northeast India, specifically Manipur, and traditionally consumed for its protective effects on human health. Due to its economic value, it is crucial to evaluate the quality of different black rice varieties to authenticate their therapeutic and nutritional properties.
    Objective: We aimed to evaluate the quality of pre- and post-marketed black rice samples by a validated high-performance thin layer chromatography method and determine variations of total phenolics and total flavonoids with antioxidant potential.
    Material and methods: The ferulic acid, gallic acid, quercetin, and caffeic acid contents of three black rice varieties-Poireiton, Amubi, and Sempak-along with two marketed samples of Amubi from Manipur, India, were quantified based on standards. Antioxidant potential was measured by the 2,2-diphenyl-1-picryl-hydrazyl hydrate free radical scavenging assay.
    Results: The highest and lowest relative biomarker contents were found in hydroalcoholic extracts of Amubi [caffeic acid (1.43% w/w), ferulic acid (1.15% w/w), quercetin (0.6% w/w), and gallic acid (0.39% w/w)] and the marketed sample Var. Amubi from Kakching District, respectively. Pearson's correlation coefficient of antioxidant potential with phenolic and flavonoid content showed a moderate to strong correlation for all samples.
    Conclusion: This validated, rapid, accurate standardization method for black rice varieties will be beneficial for the quality evaluation of black rice and its derived products. It will also be helpful to authenticate the nutritional benefits for the consumers.
