: A huge number of nitrogen-containing heterocyclic compounds are ubiquitous in natural products, pharmaceuticals, and bioactive molecules. Among these, the pyranoindole represents an important structural motif, as it constitutes the central subunit in both the biologically active natural products and therapeutic agents. Talathermophilins, notoamides, norgeamides, carneamides, and versicamides are examples of naturally occurring pyranoindoles, while the well-known etodolac and pemedolac are a tetrahydropyrano[3,4-b]indole deriving from synthetic procedures. Besides the well-known antiinflammatory and fibrinolytic activity, molecules comprising the pyranoindole framework have been demonstrated to exhibit various biological activities, such as antiulcer, antidepressant, analgesic, and antiproliferative. Herein, we report the most common natural and synthetic products bearing a pyranoindole nucleus, their syntheses, and biological activities.

In the past two decades, pandemics of several fatal coronaviruses have posed enormous challenges for public health, including SARS-CoV (2003), MERS-CoV (2012), and SARS-CoV-2 (2019). Among these, SARS-CoV-2 continues to ravage the world today and has lead to millions of deaths and incalculable economic damage. Till now, there is no clinically proven antiviral drug available for SARS-CoV-2. However, the bioactive molecules of natural origin, especially medicinal plants, have been proven to be potential resources in the treatment of SARS-CoV-2, acting at different stages of the viral life cycle and targeting different viral or host proteins, such as PLpro, 3CLpro, RdRp, helicase, spike, ACE2, and TMPRSS2. They provide a viable strategy to develop therapeutic agents. This review presents fundamental biological information on SARS-CoV-2, including the viral biological characteristics and invasion mechanisms. It also summarizes the reported natural bioactive molecules with anti-coronavirus properties, arranged by their different targets in the life cycle of viral infection of human cells, and discusses the prospects of these bioactive molecules for the treatment of COVID-19.

Aims: One of the most important resources for the development of new drugs is a biologically active lead compound from natural sources. Biomedical researchers and pharmaceutical companies have a high interest in plant-derived molecules that can be used for drug development. Background: The collective knowledge of plants and their phytoconstituents would be of great benefit for the researchers involved in drug design. Therefore, we developed a unique and dynamic database GreenMolBD, to provide collective information of medicinal plants such as their individual profile, chemical constituents and pharmacological evidence, along with their plant parts and extract types based on different studies. Objective: We have also provided a complete profile of each compound, their physical, quantum, drug-likeliness, and toxicity properties (48 type’s descriptor) using in silico tools. Method: 1846 associated targets, related to individual compounds that are already explored in different studies, are also incorporated and synchronized. Result: GreenMolBD is freely accessible and searchable by keywords, plant name, synonym, common name, family name, family synonym, compound name, synonym, IUPAC name, InChI Key, target name and disease name. Conclusion: This is the first evidence-based database of bioactive molecules from medicinal plants specially grown in Bangladesh, which may help to explore and foster nature-inspired rational drug discovery in the future. Our database is continuously updating with the new information.
