Heterocyclic Derivatives

: Over the last decades, several heterocyclic derivatives compounds have been synthesized or extracted from natural resources and have been tested for their pharmaceutical activities. Xanthene is one of these heterocyclic derivatives. These compounds consist of an oxygen-containing central heterocyclic structure with two more cyclic structures fused to the central cyclic compound. It has been shown that xanthane derivatives are bioactive compounds with diverse activities such as anti-bacterial, anti-fungal, anti-cancer, and anti-inflammatory as well as therapeutic effects on diabetes and Alzheimer. The anti-cancer activity of such compounds has been one of the main research fields in pharmaceutical chemistry. Due to this diverse biological activity, xanthene core derivatives are still an attractive research field for both academia and industry. This review addresses the current finding on the biological activities of xanthene derivatives and discussed in detail some aspects of their structure-activity relationship (SAR).

Background and Introduction: Sesquiterpene lactones are a class of secondary metabolite that contains sesquiterpenoids and lactone ring as pharmacophore moiety. A large group of bioactive secondary metabolites such as phytopharmaceuticals belong to this category. From the Asteraceae family-based medicinal plants, more than 5,000 sesquiterpene lactones have been reported so far. Sesquiterpene lactone-based pharmacophore moieties hold promise for broad-spectrum biological activities against cancer, inflammation, parasitic, bacterial, fungal, viral infection and other functional disorders. Moreover, these moiety based phytocompounds have been highlighted with a new dimension in the natural drug discovery program worldwide after the 2015 Medicine Nobel Prize achieved by the Artemisinin researchers. Objective: These bitter substances often contain an α, β-unsaturated-γ-lactone as a major structural backbone, which in recent studies has been explored to be associated with anti-tumor, cytotoxic, and anti-inflammatory action. Recently, the use of sesquiterpene lactones as phytomedicine has been increased. This study will review the prospect of sesquiterpene lactones against inflammation and cancer. Methods: Hence, we emphasized on the different features of this moiety by incorporating its structural diversity on biological activities to explore structure-activity relationships (SAR) against inflammation and cancer. Results: How the dual mode of action such as anti-inflammatory and anti-cancer has been exhibitedby these phytopharmaceuticals will be forecasted in this study. Furthermore, the correlation of anti-inflammatory and anti-cancer activity executed by the sesquiterpene lactones for fruitful phytotherapy will also be revealed in the present review in the milieu of pharmacophore activity relation and pharmacodynamics study as well. Conclusion: So, these metabolites are paramount in phytopharmacological aspects. The present discussion on the future prospect of this moiety based on the reported literature could be a guide for anti-inflammatory and anti-cancer drug discovery programs for the upcoming researchers.

Abstract Background In modern therapeutics, various human pathological disturbances were treated with the plant-based products. Waltheria indica Linn, a perennial herb, was commonly used in traditional medicine worldwide against various ailments such as cough, dysentery, diarrhea, bladder disorder, hemoptysis, inflammations, neuralgia, wounds, and ulcers. Main body The shrub was majorly distributed in tropical, subtropical regions and exists in many distinct local forms. Both the crude extracts and purified compounds from the whole plant and its parts showed wide pharmacological properties like antioxidant, analgesic, sedative, anti-bacterial, anti-fungal, and anti-parasitic. The phytochemical profile and traditional usage highlight the potency of the plant in the treatment of microbial infections and inflammatory diseases. Yet, additional studies are required for the confirmations of its traditional uses against other diseases. More detailed understanding of anti-cataract, anti-diabetics, asthma, anemia, and anti-cancer mechanism has to be explored. Though many research articles on the proposed plant are available, there has been a rising concern in the therapeutic property, especially on the alkaloids and flavonoids from this plant for drug design. Conclusion This article aims in a systematic and updated review on distribution, botany, traditional uses, phytocompounds, and relevant biological activities from each part of the plant. The information was collected from databases like PubMed, ScienceDirect, Web of Science, Google Scholar, books, dissertation, and reports via academic libraries that included more than 100 articles published since 1937. This ethnopharmacological study of the plant may create new insight into drug discovery to develop important novel leads against various biological targets.
