The benzoxazole is a heterocyclic aromatic organic compound. It is a vital pharmacophore and honoured structure in medicinal chemistry. It plays a very imperative role with quite useful therapeutic activities such as antiulcers, antihypertensives, analgesic, antiinflammatory, anti-virals, antifungals, anticancer, antidepressant activity, antilishmanial activity, anticonvulsant activity, antitubercular activity, antitumor activity, The review of the literature reveals that the benzoxazole derivatives are marvellously effective compounds and a large number of reviews available for biochemical and pharmacological studies established that their molecules are useful against a wide variety of microorganisms. Because of their prominence, the techniques for their synthesis have become an attention of synthetic organic chemists. Therefore, in the contemporary review we tried to assemble the chemistry of different derivative of substituted benzoxazole as well as various pharmacological activities and some of the important methodologies used for the synthesis.

Abstract Objectives Iris germanica L. is a medicinal plant, which has a long history of uses, mainly in medieval Persia and many places worldwide for the management of a wide variety of diseases. In this study, we aimed to review ethnopharmacological applications in addition to phytochemical and pharmacological properties of I. germanica. Key findings Ethnomedical uses of I. germanica have been reported from many countries such as China, Pakistan, India, Iran and Turkey. The medicinal part of I. germanica is the rhizome and the roots. Based on phytochemical investigations, different bioactive compounds, including flavonoids, triterpenes, sterols, phenolics, ceramides and benzoquinones, have been identified in its medicinal parts. Current pharmacological studies represent that the plant possesses several biological and therapeutic effects, including neuroprotective, hypoglycaemic, hypolipidaemic, antimicrobial, antioxidant, antiproliferative, anti-inflammatory, antiplasmodial, antifungal, immunomodulatory, cytotoxic and antimutagenic effects. Summary Although the majority of preclinical studies reported various pharmacological activities of this plant, however, sufficient clinical trials are not currently available. Therefore, to draw a definitive conclusion about the efficacy and therapeutic activities of I. germanica and its bioactive compounds, further clinical and experimental studies are required. Moreover, it is necessary to focus on the pharmacokinetic and safety studies on the extracts of I. germanica.

Nitrogen-containing heterocycles are one of the most common structural motifs in approximately 80% of the marketed drugs. Of these, benzimidazoles analogues are known to elicit a wide spectrum of pharmaceutical activities such as anticancer, antibacterial, antiparasitic, antiviral, antifungal as well as chemosensor effect. Based on the benzimidazole core fused heterocyclic compounds, crescent-shaped bisbenzimidazoles were developed which provided an early breakthrough in the sequence-specific DNA recognition. Over the years, a number of functional variations in the bisbenzimidazole core have led to the emergence of their unique properties and established them as versatile ligands against several classes of pathogens. The present review provides an overview of diverse pharmacological activities of the bisbenzimidazole analogues in the past decade with a brief account of its development through the years.

Annona atemoya also known as the custard apple is a hybrid between two Annonaceae species: Cherimoya (Annona cherimola) and the sugar apple (Annona squamosa). It is widely cultivated in tropical and subtropical continents including north and south America, Asia, Africa and Australia. Despite becoming an increasingly important commercial fruit plant due to its’ creamy succulent flesh, compared to other Annonaceae species relatively few studies have investigated the phytochemistry and bioactivities of A. atemoya. Studies that evaluated A. atemoya extracts and its constituents were searched through the databases Scopus, Pubmed and Embase from inception to June 2020. Constituents of A. atemoya include alkaloids, flavonoids, terpenes and acetogenins. The results indicate that the constituents of A. atemoya possess cytotoxic, anti-angiogenic, hypolipidemic, antioxidant, anti-inflammatory and neuroprotective activities. However, many of these studies are currently limited in quality and further phytochemical and pharmacological studies are required.

Continuing our research in the field of new heterocyclic compounds, herein we report on the synthesis and antitumor activity of new amino derivatives of pyrido[3’,2’:4,5](furo)thieno[3,2-d]pyrimidines as well as of two new heterocyclic systems: furo[2–e]imidazo[1,2-c]pyrimidine and furo[2,3-e]pyrimido[1,2-c]pyrimidine. Thus, by refluxing the 8-chloro derivatives of pyrido[3’,2’:4,5]thieno(furo)[3,2-d]pyrimidines with various amines, the relevant pyrido[3’,2’:4,5]thieno(furo)[3,2-d]pyrimidin-8-amines were obtained. Further, the cyclization of some amines under the action of phosphorus oxychloride led to the formation of new heterorings: imidazo[1,2-c]pyrimidine and pyrimido[1,2-c]pyrimidine. The possible antitumor activity of the newly synthesized compounds was evaluated in vitro. The biological tests evidenced that some of them showed pronounced antitumor activity. A study of the structure–activity relationships revealed that the compound activity depended mostly on the nature of the amine fragments. A docking analysis was also performed for the most active compounds.
