Abstract
Cannabis is a complex biosynthetic plant, with a long history of medicinal use. While cannabinoids have received the majority of the attention for their psychoactive and pharmacological activities, cannabis produces a diverse array of phytochemicals, such as terpenes. These compounds are known to play a role in the aroma and flavor of cannabis but are potent biologically active molecules that exert effects on infectious as well as chronic diseases. Furthermore, terpenes have the potential to play important roles, such as synergistic and/or entourage compounds that modulate the activity of the cannabinoids. This review highlights the diversity and bioactivities of terpenes in cannabis, especially minor or secondary terpenes that are less concentrated in cannabis on a by-mass basis. We also explore the question of the entourage effect in cannabis, which studies to date have supported or refuted the concept of synergy in cannabis, and where synergy experimentation is headed, to better understand the interplay between phytochemicals within Cannabis sativa L.

Abstract
In this study, the in vitro antimicrobial, antiparasitic, antiproliferative and cytotoxic activities of essential oil from Baccharis parvidentata Malag. (EO-Bp) and Lippia origanoides Kunth (EO-Lo) were explored. The relevant effects were observed against the parasitic protozoans Plasmodium falciparum, Trypanosoma cruzi, Trypanosoma brucei and Leishmania amazonensis (ranging 0.6 to 39.7 µg/mL) and malignant MCF-7, MCF-7/HT, 22Rv1, and A431 cell lines (ranging 6.1 to 31.5 µg/mL). In parallel, EO-Bp showed better selective indexes in comparison with EO-Lo against peritoneal macrophages from BALB/c mice and MRC-5 cell line. In conclusion, EO-Lo is known to show a wide range of health benefits that could be added as another potential use of this oil with the current study. In the case of EO-Bp, the wide spectrum of its activities against protozoal parasites and malignant cells, as well as its selectivity in comparison with non-malignant cells, could suggest an interesting candidate for further tests as a new therapeutic alternative.

Vimal A, Siddiqui MH, Verma A, Kumar A. Degradation product of curcumin restrain Salmonella typhimurium virulent protein L-asparaginase. JOURNAL OF COMPLEMENTARY & INTEGRATIVE MEDICINE 2021:jcim-2021-0172. [PMID: 34860475 DOI: 10.1515/jcim-2021-0172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Accepted: 11/14/2021] [Indexed: 11/15/2022]
Abstract
OBJECTIVES Salmonella typhimurium is a pathogen responsible for causing a wide range of infectious diseases. The emergence of multi-drug resistance (MDR) in this microbe is a big challenge. L-asparaginase (less explored drug target) is selected as a drug target because it is actively involved in the virulence mechanism. To block this virulent enzyme, curcumin that is traditionally renowned for its medicinal properties was examined. However, its pharmacological behavior and targeting property is less understood because of its poor bioavailability. Therefore, the present work explores the antimicrobial effect of both curcumin and its degradation product against the MDR pathogen. METHODS Molecular docking studies were carried out to evaluate the inhibitory effect of curcumin and its degradation product against the L-asparaginase enzyme using Schrodinger Maestro interface tools. The Absorption, Distribution, Metabolism, Excretion and Toxicity (ADMET) profile of all the test ligands was also performed. RESULTS The docking score of curcumin was -5.465 kcal/mol while its degradation product curcumin glucuronide has the lowest i.e., -6.240 kcal/mol. All the test ligands showed better or comparable docking scores with respect to control (Ciprofloxacin). Arg 142 and Asn 84 amino acid residues of L-asparaginase were found to be interacting with test ligands inside the binding pocket of the target protein. ADME/toxicology study also indicated the potency of curcumin/curcumin degradation products as a potent inhibitor. CONCLUSIONS It was found that both curcumin and its degradation products have the potential to inhibit Salmonella. This information could be valuable for futuristic drug candidate development against this pathogen and could be a potential lead for mitigation of MDR.

Abstract
Chronic inflammation is triggered by numerous diseases such as osteoarthritis, Crohn's disease and cancer. The control of the pro-inflammatory process can prevent, mitigate and/or inhibit the evolution of these diseases. Therefore, anti-inflammatory drugs have been studied as possible compounds to act in these diseases. This paper proposes a computational analysis of eugenol in relation to aspirin and diclofenac and analyzing the ADMET profile and interactions with COX-2 and 5-LOX enzymes, important enzymes in the signaling pathway of pro-inflammatory processes. Through the analysis of ADMET in silico, it was found that the pharmacokinetic results of eugenol are similar to NSAIDs, such as diclofenac and aspirin. Bioinformatics analysis using coupling tests showed that eugenol can bind to COX-2 and 5-LOX. These results corroborate with different findings in the literature that demonstrate anti-inflammatory activity with less gastric irritation, bleeding and ulcerogenic side effects of eugenol. The results of bioinformatics reinforce studies that try to propose eugenol as an anti-inflammatory compound that can act in the COX-2/5-LOX pathways, replacing some NSAIDs in different diseases.

Abstract
The present investigation studied the chemical composition of the essential oils extracted from Dracocephalum integrifolium Bunge growing in three different localities in northwest China and evaluated the phytotoxic, antimicrobial and insecticidal activities of the essential oils as well as their major constituents, i.e., sabinene and eucalyptol. GC/MS analysis revealed the presence of 21-24 compounds in the essential oils, representing 94.17-97.71% of the entire oils. Monoterpenes were the most abundant substances, accounting for 85.30-93.61% of the oils; among them, sabinene (7.35-14.0%) and eucalyptol (53.56-76.11%) were dominant in all three oils, which occupied 67.56-83.46% of the total oils. In general, phytotoxic bioassays indicated that the IC50 values of the oils and their major constituents were below 2 μL/mL (1.739-1.886 mg/mL) against Amaranthus retroflexus and Poa annua. Disc diffusion method demonstrated that the oils and their major constituents possessed antimicrobial activity against Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli, Saccharomyces cerevisiae, and Candida albicans, with MIC values ranging from 5-40 μL/mL (4.347-37.712 mg/mL). The oils, sabinene and eucalyptol also exhibited significant pesticidal activity, with the mortality rates of Aphis pomi reaching 100% after exposing to 10 μL oil/petri dish (8.694-9.428 mg/petri dish) for 24 h. To the best of our knowledge, this is the first report on the chemical composition, phytotoxic, antimicrobial and insecticidal activity of the essential oils extracted from D. integrifolium; it is noteworthy to mention that this is also the first report on the phytotoxicity of one of the major constituents, sabinene. Our results imply that D. integrifolium oils and sabinene have the potential value of being further exploited as natural pesticides.

Abstract
In chronic nonhealing wounds, the healing process is disrupted and wounds are often infected with bacteria. About 85% of lower extremity amputations in diabetes are attributed to deep infection of foot ulcers. Therefore, infection control is critical for wound care. In this study, we analyzed lipid composition of Chamaecyparis obtusa extract, and we describe the wound-healing properties of its combination of 10 major lipid components. A 10-lipid mixture up-regulated HBD-3 and LL-37 through the olfactory receptor 2AT4 and induced phosphorylation of extracellular signal-regulated kinases and p38 mitogen-activated protein kinases in primary human keratinocytes. In addition, the 10-lipid mixture had direct bactericidal effects against Staphylococcus aureus and Streptococcus pyogenes and protected against staphylococcal α-toxin-induced keratinocyte cell death. In an animal model, the 10-lipid mixture accelerated skin wound healing and was also effective in healing wounds superinfected with S. aureus. We suggest that the 10-lipid mixture, because of its wound-healing and antimicrobial properties, can be beneficial for wound treatment.

Abstract
Salmonella typhimurium is the causative agent of severe human infections and mortality throughout the world. Pacing advent of new resistance mechanisms in this microorganism exists, rendering treatment of infectious disease difficult. Ciprofloxacin is no longer considered the first choice of antimicrobial agent due to the emergence of resistance. Therefore, the need for scenario is to find out novel drug target and its potential inhibitor to fight against this pathogen. The present study was undertaken to find out a novel drug target and its inhibitor for improving the current therapeutic methods for treating Salmonella infections. It is found that l-asparaginase is exploited by the pathogen for its survival benefit. Therefore, it could be targeted to fight against lethality caused by Salmonella infections. In the present in silico study, the 3-D structure of the enzyme l-asparaginase was modelled by using homology modeling technique. Thereafter, molecular docking studies and ADMET prediction to assess pharmacokinetic profiles of test ligands (eugenol and its derivative) was performed. The results show that eugenol and its derivative are capable of inhibiting the Salmonella virulent protein l-asparaginase. There were 18 ligands including ciprofloxacin (used as reference) were docked. The lowest binding energy was observed with eugenol derivative 8 i.e -5.836 kcal/mol while for ciprofloxacin was -4.661 kcal/mol. The docking of the eugenol derivative 8 with l-asparaginase revealed a strong interaction between them with two hydrogen bonds. Thr 35 and Asp 116 residues are actively participating in this interaction. The result of ADMET profiling suggests the potency of eugenol and its derivatives against Salmonellal-asparaginase-II as a compelling drug candidate. These findings provide useful information on the biological role, structure-based drug design and potent inhibitor of l-asparaginase for the development of effective therapeutic molecule against Salmonella infection.
