Bassia indica (Wight) A.J. Scott is an Indian origin plant with documented medicinal and nutritional value, but has not been fully characterized yet. The present study was designed to establish pharmacognostic standards for the proper identification of the B. indica plant and its chemical characterization. The plant was standardized with World Health Organization (WHO) standardization tools and chemically characterized by Fourier transform infrared spectroscopy (FTIR) and gas chromatography-mass spectroscopy (GC-MS) analysis. Antibacterial potential was assessed by the zone of inhibition and minimum inhibitory concentration (MIC), and molecular docking studies were also performed. Pharmacognostic evaluation established the macroscopic and microscopic parameters for the identification of whole plant and its powder. Physicochemical parameters were also set forth while quantitative phytochemical analysis showed that the ethyl acetate fraction had the highest quantity of phenols, flavonoids, and tannins. FTIR analysis showed several functional groups such as phenols, alkanes, and alcohols while 55 phytochemicals were identified in the GC-MS analysis of the crude fraction. The crude extract and other fractions showed marked antibacterial activity, while the ethyl acetate fraction showed the least MIC (1.95–31.25 mg/mL). Phytochemicals identified in the GC-MS showed good molecular docking interactions against the DNA gyrase subunit B of bacteria with binding energies ranging from −4.2 to −9.4 kcal/mol. The current study describes the pharmacognostic characterization and phytochemical profiling of B. indica and provides scientific evidence to support its use in infections.

Dear Editor: Mankind has been using plants as food and medicine for centuries. This interaction has enabled them to understand the harms and benefits achievable through them thus laying down the foundation of traditional knowledge of medicinal plants (Ghorbani et al., 2006; Sulejman, 2007). The term “Ethnopharmacology” was first used in 1967. Since then it has been used as a valuable tool for drug discovery (Heinrich and Gibbons, 2001). Ethnopharmacology is an interdisciplinary field focusing on the scientific study and experimentation to prove and validate the traditional uses of plants and other natural products. It also includes the study of the bioactive compounds present in these products so that they can be synthesized on a commercial basis. Ethnopharmacology plays an important role in the preservation of the cultural heritage. It also identifies the harmful effects of many traditional therapies and provides an up to date knowledge and assistance to the herbal practitioners. Ethnopharmacological studies are a result of combined efforts of scientists from many fields mainly, botany, pharmacology and chemistry (Holmstedt and Bruhn, 1983; Heinrich et al., 2006). The source of information to carry out various studies comes from ethnobotanical and ethnomedical literature. Thus, ethnopharmacology proves the traditional claims in a scientific manner (Waller, 1993). The study of biological activities may involve the use of different in vitro or in vivo models. Both approaches have several advantages and disadvantages. The decision whether to use an in vivo or in vitro assay is made after considering many factors. For example if the amount of sample under study is high and sufficient financial resources are available, in vivo assay may be preferred if there are no ethical issues under debate. These assays will give a better picture of the medicinal activity of the plant. However if there is time limitation, inadequate funds or less sample volume, an in vitro assay will be a better choice in such case (Houghton et al., 2007). After the successful completion of a series of different assays and proving of significant biological activities, the medicinal plant is subjected to the drug development process (Cordell and Colvard, 2005). Besides the ethno-directed approach, the selection of plants for pharmacological screening may be based on random screening in which all of the plants belonging to any specific area are selected and tested for different activities. Thus, random screening does not require any proper justification through literature. The plants can also be selected for study if they are rich in phytochemicals or if other members of the family to which it belongs, possess biological activities. The latter is because many associated species possess similar phytochemicals (Waller, 1993; Ghorbani et al., 2006; Rout et al., 2009). This property has specially been noticed in the case of alkaloids. Random screening and phytochemical approach has been found to be very beneficial in discovering new leads especially when folk knowledge is unavailable. These prevent many plants from being ignored due to lack of supporting information (Ghorbani et al., 2006). The two methods however prove to be costly as compared to ethnopharmacological approach as considerable amount of resources are wasted during the trial and error procedure. Biological studies are usually considered to be preliminary. Due to unavailability of costly instruments for phytochemical studies, scientists from developing countries with large flora fail to disseminate their findings on large scale through publication in high impact journals.

The present study was aimed to investigate the phytochemistry of the three plants namely, Conocarpus lancifolius, M. decora and S. podophyllum. Secondary metabolite enriched extracts of alkaloids, phenolics and saponins prepared directly from the plant powder were subjected to thin layer chromatography using simple solvent systems. The compounds separated were observed using different techniques. All three plants showed the presence of large number of alkaloids, phenolics and saponins in them thus indicating the presence of high chemical diversity and therapeutic potential.

Context: The ongoing challenges with chemotherapy demand continuous efforts to discover new drug molecules. In this scenario, a multi-target approach could be of special advantage. This might not only decrease the likelihood of drug resistance but also ensure a broader spectrum and a multifaceted, convergent attack on tumor cells. In this context, anthracene-based compounds are of key interest. Aims: To explore the activity and hybrid nature of acridine-based derivatives. Methods: In silico approach was applied, and the compounds were tested against seven different protein targets playing significant roles in cancer pathogenesis. Results: Based on the binding affinities of the compounds, it was found that, in addition to being excellent intercalating agents, the compounds displayed high inhibition for several protein targets, most importantly tyrosine kinases. Specifically, the ligands with imidazole and hydroxyethyl amino groups were found to be potent against all targets except for EGFR and ROS. The docking scores of the tested compounds were higher than those of the standard drugs in many instances. In silico ADME prediction showed that all compounds fell within the prescribed ranges, thus making them ideal candidates for oral delivery. Conclusions: The proposed compounds not only demonstrated strong anticancer activity but also exhibited their activity through multiple pathways, thereby overcoming several therapeutic challenges currently faced.
