Cleome Viscosa

Cleome viscosa belonging to the family Capparidaceae, is a weed with ethano-botanical value found in India. In the present investigation, methanolic extract of Cleome viscosa was analyzed by gas chromatography-mass spectrometry (GC-MS) to identify the important phytochemical constituents. The GC-MS analysis of methanol from whole plant of Cleome viscosa detected the presence of 78 phytochemical compounds. Quantitative phytochemical evaluation of the methanolic extract of Cleome viscosa was performed. These identified compounds were analyzed for their anticancer activity through in silico molecular docking studies. Computation based in silico docking studies were done using maestro interface. Three protein, poly (ADP-ribose) polymerase-1 (PARP-1), epidermal growth factor receptor (EGFR), human papilloma virus (HPV) specific to different cancers were selected for screening of these phytochemicals. Phytomolecules with better activity and binding were shortlisted after XP mode of docking. The dock score, glide energy and 2D binding interactions of the top five phytochemicals with three selected proteins have been discussed. The identified hit could be a potent inhibitor these proteins that further requires experimental validation.

Background: Cancer being a deadly disease, many reports of new chemical entities are available. Pyranopyrazole (PPZ) compounds have also been disclosed as bioactive molecules but mainly as antimicrobial agents. Based on one previous report and our interest in anticancer drug design, we decided to explore PPZs as anticancer agents. To the best of our knowledge, we found that a comprehensive study, involving synthesis, in-vitro biological activity determination, exploration of the mechanism of inhibition and finally in-silico docking studies, was missing in earlier reports. This is what the present study intends to accomplish. Methods: Ten spiro and eleven non-spiro PPZ molecules were synthesized by environment-friendly multicomponent reaction (MCR) strategy. After subjecting each of the newly synthesized molecules to Hep3b hepatocellular carcinoma cell lines assay, we selectively measured the Optical Density (OD) of the most active ones. Then, the compound exhibiting the best activity was docked against human CHK- 1 protein to get an insight into the binding affinities and a quick structure activity relationship (SAR) of the PPZs. Results: The two series of spiro and non-spiro PPZs were easily synthesized in high yields using microwave assisted synthesis and other methods. Among the synthesized compounds, most compounds showed moderate to good anticancer activity against the MTT assay. After performing the absorbance studies we found that the non-spiro molecules showed better apoptosis results and appeared to bind to DNA causing disruption in their structures. Finally, the docking results of compound 5h (having N,Ndimethylamino substituted moiety) clearly showed good binding affinities as predicted by our experimental findings. Conclusion: The paper describes a comprehensive synthesis, in-vitro and docking studies done on new PPZs. The newly synthesized series of spiro and non-spiro PPZs were found to possess antineoplasmic activity as evinced by the studies on hep3b cells. Also, the UV visible absorbance study gave clues to the possible binding of these molecules to the DNA. Docking studies corroborated well with the experimental results. Thus, these new molecules appear to be potential anticancer agents, but further studies are required to substantiate and elaborate on these findings.

Abstract Background In the wake of emergence of antimicrobial resistance, bioactive phytochemical compounds are proving to be important therapeutic agents. The present study envisaged in silico molecular docking as well as in vitro antimicrobial efficacy screening of identified phytochemical ligands to the dispersin (aap) and outer membrane osmoporin (OmpC) domains of enteroaggregative Escherichia coli (EAEC) and non-typhoidal Salmonella spp. (NTS), respectively. Materials and methods The evaluation of drug-likeness, molecular properties, and bioactivity of the identified phytocompounds (thymol, carvacrol, and cinnamaldehyde) was carried out using Swiss ADME, while Protox-II and StopTox servers were used to identify its toxicity. The in silico molecular docking of the phytochemical ligands with the protein motifs of dispersin (PDB ID: 2jvu) and outer membrane osmoporin (PDB ID: 3uu2) were carried out using AutoDock v.4.20. Further, the antimicrobial efficacy of these compounds against multi-drug resistant EAEC and NTS strains was determined by estimating the minimum inhibitory concentrations and minimum bactericidal concentrations. Subsequently, these phytochemicals were subjected to their safety (sheep and human erythrocytic haemolysis) as well as stability (cationic salts, and pH) assays. Results All the three identified phytochemicals ligands were found to be zero violators of Lipinski’s rule of five and exhibited drug-likeness. The compounds tested were categorized as toxicity class-4 by Protox-II and were found to be non- cardiotoxic by StopTox. The docking studies employing 3D model of dispersin and ompC motifs with the identified phytochemical ligands exhibited good binding affinity. The identified phytochemical compounds were observed to be comparatively stable at different conditions (cationic salts, and pH); however, a concentration-dependent increase in the haemolytic assay was observed against sheep as well as human erythrocytes. Conclusions In silico molecular docking studies provided useful insights to understand the interaction of phytochemical ligands with protein motifs of pathogen and should be used routinely before the wet screening of any phytochemicals for their antibacterial, stability, and safety aspects.

In this work, some 2-phenyl quinoline-4-carboxamide derivatives (5a-j) were synthesized via base catalyzed Pfitzinger reaction of isatin and acetophenone followed by C-N coupling reaction using POCl3 and assessed them for their in vitro antimicrobial and anticancer activity. The structure of newly synthesized compound were established by FT-IR, 1H & 13C NMR and Mass spectrometric analysis. The synthesized carboxamides were subjected to preliminary in vitro antibacterial activity as well as for antifungal activity. Results of antibacterial activity were compared with standard antibacterial (ciprofloxocin) and antifungal (fluconozole). Among the tested compounds, 5d, 5f and 5h exhibited promising activity with zone of inhibition ranging from 10 to 25 mm. Further, the anticancer activity determined using MTT assay against two cancer cell lines. Compounds 5b, 5d, 5f and 5h showed good anticancer activity among all the other derivatives. In order to correlate the in vitro results, in silico ADME and Molecular docking studies were carried out for (5a-j). ADME properties results showed that all the compounds obey rule of Five rule except 5a, 5e and 5g compound. Molecular docking studies of the synthesized compounds showed good binding affinity through hydrogen bond interactions with key residues on active sites as well as neighboring residues within the active site of chosen target proteins viz. antibacterial, antifungal and anticancer. Comparison of both results of in silico as well as in vitro investigation suggests that the synthesized compounds may act as potential antimicrobial as well as anticancer agents.
