Rhododendron is one of the plants with the broadest spectrum species, the most extended history of traditional medicine use, and the wide range of pharmacological properties. In 2013, a report was published to summarize the studies reported from 1898 to 2012. Many phytochemical compounds and their various treatment effects of over 40 Rhododendron species were mentioned in the present review. This review aims to evaluate the newly discovered and observed phytochemical compounds in recent years and their activities in some Rhododendron species.

Azetidin-2-ones (β-lactams) and its derivatives are an important group of heterocyclic compounds that exhibit a wide range of pharmacological properties such as antibacterial, anticancer, anti-diabetic, anti-inflammatory and anticonvulsant. Efforts have been made over the years to develop novel congeners with superior biological activities and minimal potential for undesirable side effects. The present review aimed to highlight some recent discoveries (2013-2019) on the development of novel azetidin-2-one-based compounds as potential anticancer agents.

The plant is used in folk medicine for numerous ailments such as hemorrhoids, antifertility, diarrhea, and dyspepsia. Its medicinal usage in Unani, Ayurveda, Siddha, and other traditional medicine is well-recognized. So far, a wide range of active phytochemicals of this plant has been identified, such as flavonoids, sulphated flavonoids, terpenoids, anthraquinones, steroids, coumarin, simple phenolics, and others. Pharmacological data reported in the literature suggest that various parts of P. hydropiper exhibit antimicrobial, antioxidant, hypoglycemic, antidepressant, cardioprotective, hepatoprotective, anticancer, and antifertility effects. The present review aim is to compile the coherently document research on the phytochemical, pharmacological, and biological activities of P. hydropiper from different parts of the globe.

Asperugo procumbens is a medicinal plant widely distributed in the world, which is commonly used in the traditional medicine of the Middle East, while currently overlooked in European pharmacopoeias. The aim of the study is to present a comprehensive overview of A. procumbens in botany, traditional medicine, phytochemistry and pharmacology according to the up-to-date data. Scientific literature on the species was collected based on publicly available databases such as: PubMed, Web of Science, Scopus, Google, Google Scholar as well as monographs and PhD theses. In traditional medicine the aerial part of A. procumbens is used for treatment of skin infections, herpes, liver and respiratory tract diseases, to strengthen the heart and the nervous system, and others. Contemporary studies on the pharmacological activity of A. procumbens revealed that it exhibits a wide range of pharmacological properties, including antioxidant, antidepressant, sedative-hypnotic, antibacterial, as well as chemopreventive and antihypertensive properties. Despite many proven medicinal properties, the species does not have a developed phytochemical profile and its chemical composition is very poorly understood. The species is known to contain tannins, flavonoids and phenolics. Only the content of fatty acids is recognised in detail. The species is a good source of omega-3 fatty acids – stearidonic acid (SDA), α-linolenic acid (ALA), and omega-6 fatty acid – γ-linolenic acid (GLA). This article, based on the available literature, highlights the traditional uses, phytochemistry and pharmacological properties of A. procumbens, which may provide a foundation for further pharmacological study as well as clinical application of the species. Keywords: Asperugo procumbens, German madwort, Boraginaceae, traditional uses

Background: This paper reviews the research progress of pyrazoloquinazolines which widely used in the field of medicine and pesticide in recent years. Five types of pyrazoloquinazolines are introduced: pyrazolo [4,3-h]quinazolines, pyrazolo[1,5-c]quinazolines, pyrazolo[4,3-f]quinazolines, pyrazolo[1,5-a] quinazolines , pyrazolo[1,5-b]quinazolines, and their new progress in the synthesis methods and treatment of diseases. Methodology: The derivatives of pyrazoloquinazolines exhibit a wide range of pharmacological properties such as antibacterial, anticancer, antioxidants, anti-inflammatory, anti-diabetic, antiviral activities. Consequently, their syntheses have attracted significant interest. Various methodologies have been developed for the synthesis and functionalization of these class of compounds. Conclusion: In the present article, the relevant and recent advances in the field will be briefly covered.

Bandotan (Ageratum conyzoides L.) is a plant belonging to the Asteracea family. This plant is widely used as medicine in various countries such as Africa, Asia and South America. Bandotan is used as medicine because it contains useful phytochemical compounds such as terpenoids, alkaloids, essential oils, saponins and phenolics. Some of the pharmalogical activities on bandotan include antibacterial, anti-inflammatory, antioxidant, and antidiabetic. Several studies have shown that bandotan can be used as a treatment for fever, rheumatism, headaches, stomach aches, medicine for pneumonia, drugs for diarhea, diabetes, and HIV/AIDS. The article review is expected to provide information about the use of bandotan as a traditional medicine or herbal medicine and its pharmacological activity.

Cordyceps militaris, a traditional medicinal ingredient with a long history of application in China, is regarded as a high-value fungus due to its production of various bioactive ingredients with a wide range of pharmacological effects in clinical treatment. Several typical bioactive ingredients, such as cordycepin, D-mannitol, cordyceps polysaccharides, and N6-(2-hydroxyethyl)-adenosine (HEA), have received increasing attention due to their antitumor, antioxidant, antidiabetic, radioprotective, antiviral and immunomodulatory activities. Here, we systematically sorted out the latest research progress on the chemical characteristics, biosynthetic gene clusters and pathways of these four typical bioactive ingredients. This summary will lay a foundation for obtaining low-cost and high-quality bioactive ingredients in large amounts using microbial cell factories in the future.

Schefflera umbellifera (Sond.) Baill. is an evergreen tree widely used as traditional medicine throughout its distributional range in southern Africa. Schefflera umbellifera is indigenous to Eswatini, Malawi, Mozambique, South Africa and Zimbabwe. This study was aimed at providing a critical review of medicinal uses, phytochemical and pharmacological properties of S. umbellifera. Documented information on medicinal uses, phytochemical and pharmacological properties of S. umbellifera was collected from several online sources such as Scopus, Google Scholar, PubMed, Francis and Taylor and Science Direct, and pre-electronic sources such as book chapters, books, journal articles and scientific publications obtained from the University library. This study revealed that the bark, leaf and root decoction or infusion of S. umbellifera are mainly used as diuretic, laxative, colic and protective charm, and traditional medicine for stomach ulcers, weaning infants, insanity, inflammation, rheumatism and malaria. Phytochemical compounds identified from the species include 3-hydroxy-20(29)-lupen-28-ol, 7-hydroxy-6-methoxycoumarin, betulin, ent-kaur-16-en-19-oic acid and oleanolic acid. Pharmacological research revealed that S. umbellifera extracts and compounds isolated from the species have antibacterial, anti-HIV, anti-inflammatory, antimalarial, antiprotozoal, larvicidal and cytotoxicity activities. Schefflera umbellifera should be subjected to detailed phytochemical, pharmacological and toxicological evaluations aimed at correlating its medicinal uses with its phytochemistry and pharmacological activities.
