Aim: Procaine-derived carbon dots, termed P-dots, expectedly offer both fluorescent biomarker function and anticancer activity. Materials & methods: P-dots were synthesized by condensing procaine, citric acid and ethylenediamine via hydrothermal synthesis and characterized by transmission electron microscopy, Fourier transform infrared spectroscopy and x-ray photoelectron spectroscopy. The cellular uptake behavior and the bioimaging performance of P-dots were assessed by confocal laser scanning microscopy. Their antitumor activity was evaluated using the CCK-8 assays and in vivo antitumor experiments, and the underlying mechanism was evaluated by flow cytometry and western blotting. Results: P-dots exhibited excellent luminescence properties suitable for bioimaging and considerable anticancer activity associated with caspase-3-related cell apoptosis. Conclusion: The synthesized procaine-derived carbon dots presented a dual function consisting of bioimaging and anticancer activity, which may enable their implementation as safe and effective clinical nanotherapeutics.

St. John s Wort (SJW) or Hypericum perforatum L. is a therapeutic plant highly used in pharmacology. Recent in vivo anti-cancer action of naphtodianthrones (NTs) has extended the research related to enrichment methodologies of SJW phyto-extracts. Therefore, the presented study pursuits the optimization of single-step extraction methodologies to obtain NTs-rich extracts from SJW.

Background: Genus Berberis (family Berberidaceae), which contains about 650 species and 17 genera worldwide, has been used in folklore and various traditional medicine systems. Berberis Linn. is the most established group among genera with around 450-500 species across the world. This comprehensive review will not only help researchers for further evaluation but also provide substantial information for future exploitation of species to develop novel herbal formulations. Objective: The present review is focussed to summarize and collect the updated review of information of Genus Berberis species reported to date regarding their ethnomedicinal information, chemical constituents, traditional/folklore use, and reported pharmacological activities on more than 40 species of Berberis. Conclusion: A comprehensive survey of the literature reveals that various species of the genus possess various phytoconstituents mainly alkaloids, flavonoid based compounds isolated from different parts of a plant with a wide range of pharmacological activities. So far, many pharmacological activities like anti-cancer, anti-hyperlipidemic, hepatoprotective, immunomodulatory, anti-inflammatory both in vitro & in vivo and clinical study of different extracts/isolated compounds of different species of Berberis have been reported, proving their importance as a medicinal plant and claiming their traditional use.

Ferula hermonis Boiss, is an endemic plant of Lebanon, locally known as “shilsh Elzallouh”. It has been extensively used in the traditional medicine as an aphrodisiac and for the treatment of sexual impotence. Crude extracts and isolated compounds of ferula hermonis contain phytoestrogenic substances having a wide spectrum of in vitro and in vivo pharmacological properties including anti-osteoporosis, anti-inflammatory, anti-microbial and anti-fungal, anti-cancer and as sexual activity enhancer. The aim of this mini-review is to highlight the traditional and novel applications of this plant’s extracts and its major sesquiterpene ester, ferutinin. The phytochemical constituents and the pharmacological uses of ferula hermonis crude extract and ferutinin specifically will be discussed.

Background: Arnica montana, containing helenalin as its principal active constituent, is the most widely used plant to treat various ailments. Recent studies indicate that Arnica and helenalin provide significant health benefits, including anti-inflammatory, neuroprotective, antioxidant, cholesterol-lowering, immunomodulatory, and most important, anti-cancer properties. Objective: The objective of the present study is to overview the recent patents of Arnica and its principal constituent helenalin, including new methods of isolation, and their use in the prevention of cancer and other ailments. Methods: Current prose and patents emphasizing the anti-cancer potential of helenalin and Arnica, incorporated as anti-inflammary agents in anti-cancer preparations, have been identified and reviewed with particular emphasis on their scientific impact and novelty. Results: Helenalin has shown its anti-cancer potential to treat multiple types of tumors, both in vitro and in vivo. It has also portrayed synergistic effects when given in combination with other anti- cancer drugs or natural compounds. New purification/isolation techniques are also developing with novel helenalin formulations and its synthetic derivatives have been developed to increase its solubility and bioavailability. Conclusion: The promising anti-cancer potential of helenalin in various preclinical studies may open new avenues for therapeutic interventions in different tumors. Thus clinical trials validating its tumor suppressing and chemopreventive activities, particularly in conjunction with standard therapies, are immediately required.

Background: Over the past five years, the cold atmospheric plasma-activated solutions (PAS) have shown their promissing application in cancer treatment. Similar as the common direct cold plasma treatment, PAS shows a selective anti-cancer capacity in vitro and in vivo. However, different from the direct cold atmospheric plasma (CAP) treatment, PAS can be stored for a long time and can be used without dependence on a CAP device. The research on PAS is gradually becoming a hot topic in plasma medicine. Objectives: In this review, we gave a concise but comprehensive summary on key topics about PAS including the development, current status, as well as the main conclusions about the anti-cancer mechanism achieved in past years. The approaches to make strong and stable PAS are also summarized.

Background: Propofol, a widely used intravenous anesthetic agent, is traditionally applied for sedation and general anesthesia. Explanation: Recent attention has been drawn to explore the effect and mechanisms of propofol against cancer progression in vitro and in vivo. Specifically, the proliferation-inhibiting and apoptosis-inducing properties of propofol in cancer have been studied. However, the underlying mechanisms remain unclear. Conclusion: This review focused on the findings within the past ten years and aimed to provide a general overview of propofol's malignance-modulating properties and the potential molecular mechanisms.

Background: The leaves of Annona reticulata Linn. have been traditionally used by the tribes of Assam as a source of medicine to mitigate a range of health ailments including diabetes and obesity. Objectives: The current study aimed to evaluate the anti-diabetic and anti-hyperlipidemic potential of bioactive fractions isolated from the methanolic extract of Annona reticulata Linn. leaves using Nicotinamide + Streptozotocin (60 mg/kg, i.p.) induced diabetic rats. Methods: The partially purified bioactive fractions, namely F1, F2, F3 and F4 were administered to diabetic rats with the dose of 200 mg/kg, per oral (p.o.) and the effect of the fractions on serum glucose were studied up to 21 days. The potent fractions were further subjected for spectral analysis for identification of the isolated active compounds. Results: The in-vivo anti-diabetic activity of the isolated fractions F2 and F3 were found significant controlling blood glucose level, alike glibenclamide. Interestingly, F2 and F3 treated animals were found significant in restoring the lipid and liver enzymes profile in streptozotocin challenge rats. Further, spectral analysis revealed that F2 and F3 were comprises Quercetin and Gallic acid, respectively. Conclusion: Outcome of finding demonstrate the anti-diabetic and anti-hyperlipidemic potential of the isolates/fractions of A. reticulata, which were found enriched in polyphenolics including Quercetin and Gallic acid; and provides logistic behind the traditional use of the A. reticulata against Diabetes and obesity.
