There are abundant natural diterpenoids in the plants of the genus Daphne from the Thymelaeaceae family, featuring a 5/7/6-tricyclic ring system and usually with an orthoester group. So far, a total of 135 diterpenoids has been isolated from the species of the genus Daphne, which could be further classified into three main types according to the substitution pattern of ring A and oxygen-containing functions at ring B. A variety of studies have demonstrated that these compounds exert a wide range of bioactivities both in vitro and in vivo including anticancer, anti-inflammatory, anti-HIV, antifertility, neurotrophic, and cholesterol-lowering effects, which is reviewed herein. Meanwhile, the fascinating structure–activity relationship is also concluded in this review in the hope of providing an easy access to available information for the synthesis and optimization of efficient drugs.

Background: Plants from the genus Nymphaea L. have been used for decades to treat various diseases, including dysentery, diarrhea, uterine cancer, gonorrhea, inflammation conditions, among others. The present study aims to critically analyze comprehensive literature on ethnopharmacological uses, phytochemistry, pharmacology, and toxicity of Nymphaea L. Methods: The available information on Nymphaea L. was obtained from textbooks, theses, as well as published articles through libraries, and electronic databases. Results: More than 150 compounds, including flavonoids, phenolics, alkaloids, miscellaneous compounds, etc. were identified from Nymphaea L. extracts and pure molecules from Nymphaea L. exhibited a wide range of pharmacological activities, including antimicrobial, anti-inflammatory, anticancer, immunomodulatory, hepatoprotective, antioxidant, cytotoxic, among others. Conclusion: Referring to in vitro and in vivo studies, Nymphaea sp. are very promising medicinal plants, however, more in vivo experiments, cytotoxicity tests, and detailed mechanisms of action of their extracts, and compounds are recommended to confirm their ethnomedicinal claims into scientific rationale-based information.

Fusidic acid (FA) is a natural tetracyclic triterpene isolated from fungi, which is clinically used for systemic and local staphylococcal infections, including methicillin-resistant Staphylococcus aureus and coagulase-negative staphylococci infections. FA and its derivatives have been shown to possess a wide range of pharmacological activities, including antibacterial, antimalarial, antituberculosis, anticancer, tumor multidrug resistance reversal, anti-inflammation, antifungal, and antiviral activity in vivo and in vitro. The semisynthesis, structural modification and biological activities of FA derivatives have been extensively studied in recent years. This review summarized the biological activities and structure–activity relationship (SAR) of FA in the last two decades. This summary can prove useful information for drug exploration of FA derivatives.

: 1, 2, 4-Triazine derivatives have received much attention due to their multifunctional nature, especially in diverse pharmacological properties as well as a key fragment in many drug candidates. Introduction of a vicinal 5, 6-diaryl/heteroaryl moiety on the 1, 2, 4-triazine ring has attracted plentiful attention in the field of medicinal chemistry. 5, 6-Diaryl/heteroaryl-3-substituted-1, 2, 4-triazine is as a prominent scaffold in many drug candidates which has shown a wide range of pharmacological activities such as anti-diabetic, antifungal, anti-inflammatory, anticancer, anti-HIV, neuroprotective, anticonvulsant, anti- Alzheimer, anti-Parkinson and antioxidant. In this review, we have discussed synthesis, various pharmacological activities of 5, 6-diaryl/heteroaryl-3-substituted-1, 2, 4-triazines, their structure-activity relationship (SAR), pharmacophoric elements and their mechanism of action reported in the published articles during 2000-2019. Evaluation of compounds by PAINS filtering tool was accomplished and showed that this versatile structure could be considered as a privileged structure. Compilation of the biological data confirmed that the position 3 of the 1,2,4-triazine is a key location to determine the affinity and selectivity of the 5,6-diaryl/heteroaryl-3-substituted-1, 2, 4-triazines towards different biologic targets. Specific geometrical and thermodynamic characters of this motif have prompted it as a frequent hitter.

Background: Dysphania ambrosioides (L.) Mosyakin & Clemants is an aromatic herb native to South America, but also distributed widely throughout Africa and Europe. This plant is traditionally used to treat various ailments including, pain and swellings, flu, parasitic diseases, and as analgesic, antipyretic, and wound healing. Phytochemical analyses of D. ambrosioides revealed the presence of terpenoids, flavonoids, coumarins, fatty acids and miscellaneous compounds among others, which might be responsible for its modern pharmacological actions. Objective: The present work summarizes recent developments on phytochemistry, ethnomedicinal use, pharmacology, and toxicity of D. ambrosioides. A critical assessment of the literature information of D. ambrosioides is also presented. Methods: The available information on D. ambrosioides was collected through libraries and electronic databases [Scifinder, ACS, Scielo, Science direct, Pubmed (National Library of Medicine), Wiley, Springer, PROTA, Web of Science, Google Web, Yahoo search and Google scholar] from respective inception until january 2021. Results: More than 150 compounds, including terpenoids, flavonoids, coumarins, fatty acids, and miscellaneous compounds etc.. were identified from D. ambrosioides. D. ambrosioides exhibited a wide range of pharmacological activities, including antimalarial, anti-inflammatory, antiparasitic, anticancer, insecticidal, antigiardial, among others. Metal nanoparticles synthesized from D. ambrosioides extracts presented enhanced pharmacological activities as compared to the crude plant extracts counterparts. Conclusion: D. ambrosioides is a promising medicinal plant, however, more in vivo experiments, cytotoxicity tests, and mechanisms of actions of its extracts and compounds are recommended to transubstantiate the ethnomedicinal claims of this plant into scientific rationale-based information.

Curcumin is a compound extracted from the Curcuma longa L, which possesses a wide range of pharmacological effects. However, few studies have collected scientific evidence on its dual effect on angiogenesis. The present review gathered the fragmented information available in the literature to discuss the dual effect and possible mechanisms of curcumin on angiogenesis. Available information concerning the effect of curcumin on angiogenesis is compiled from scientific databases, including PubMed and Web of Science using the key term (curcumin and angiogenesis). The results were reviewed to identify relevant articles. Related literature demonstrated that curcumin has antiangiogenesis effect via regulating multiple factors, including proangiogenesis factor VEGF, MMPs, and FGF, both in vivo and in vitro, and could promote angiogenesis under certain circumstances via these factors. This paper provided a short review on bidirectional action of curcumin, which should be useful for further study and application of this compound that require further studies.

Plants of the genus Vitex (Verbenaceae) are mainly distributed throughout tropical and temperate regions, and many Vitex plants have been traditionally used in folk medicine. Plants of this genus are a rich source of diterpenoids, which not only displayed versatile structural diversity with potential chemotaxonomical significance but also exhibited a wide range of biological activities, mainly including in vitro cytotoxic, antiinflammatory, antimicrobial, hormone level-regulating and antiangiogenic activities. Recently, a series of bioactive diterpenoids, with interesting carbon skeletons, have been reported and gathered considerable interest. This article systematically reviewed diterpenoids isolated from the genus Vitex that appeared in the literature up to December 2018, critically highlighting their structural diversity and pharmacological activities. Up to now, a total of 154 diterpenoids with diverse structures have been isolated and identified from Vitex plants. The authors also summarized the reported structure-activity relationships of those well explored Vitex diterpenoids. Finally, the authors discussed the challenges and potential applications of these diterpenoids in the future.
