Chemopreventive Activities of Phytochemicals
Inflammation is caused by a variety of stimuli including physical damage, UV irradiation, microbial invasion, and immune reactions. The classical key features of inflammation are redness, warmth, swelling, and pain, and their cascades can lead to the inflammatory bowel disease and psoriasis. Many inflammatory diseases are becoming common among the elderly worldwide. Clinically used anti-inflammatory drugs suffer from the disadvantages of side effects and high treatment costs in the case of biologics. Therefore, research on new anti-inflammatory molecules and the elucidation of their molecular mechanisms are being actively conducted. This Special Issue on "Chemopreventive Activities of Phytochemicals" is intended to offer anti-inflammatory active natural products as candidates and/or leads for pharmaceuticals. The research fields of this Special Issue include natural products, chemistry, phytochemistry, pharmacognosy, food chemistry, bioorganic synthetic chemistry, chemical biology, molecular biology, molecular pharmacology, and other related research fields
Pharmacological Properties, Molecular Mechanisms, and Pharmaceutical Development of Asiatic Acid: A Pentacyclic Triterpenoid of Therapeutic Promise
Asiatic acid (AA) is a naturally occurring aglycone of ursane type pentacyclic triterpenoids. It is abundantly present in many edible and medicinal plants including Centella asiatica that is a reputed herb in many traditional medicine formulations for wound healing and neuropsychiatric diseases. AA possesses numerous pharmacological activities such as antioxidant and anti-inflammatory and regulates apoptosis that attributes its therapeutic effects in numerous diseases. AA showed potent antihypertensive, nootropic, neuroprotective, cardioprotective, antimicrobial, and antitumor activities in preclinical studies. In various in vitro and in vivo studies, AA found to affect many enzymes, receptors, growth factors, transcription factors, apoptotic proteins, and cell signaling cascades. This review aims to represent the available reports on therapeutic potential and the underlying pharmacological and molecular mechanisms of AA. The review also also discusses the challenges and prospects on the pharmaceutical development of AA such as pharmacokinetics, physicochemical properties, analysis and structural modifications, and drug delivery. AA showed favorable pharmacokinetics and found bioavailable following oral or interaperitoneal administration. The studies demonstrate the polypharmacological properties, therapeutic potential and molecular mechanisms of AA in numerous diseases. Taken together the evidences from available studies, AA appears one of the important multitargeted polypharmacological agents of natural origin for further pharmaceutical development and clinical application. Provided the favorable pharmacokinetics, safety, and efficacy, AA can be a promising agent or adjuvant along with currently used modern medicines with a pharmacological basis of its use in therapeutics
Medicinal properties of Saudi Arabian flora extracts
Infectious diseases account for increasing levels of mortality around the world. When
microorganisms overcome epithelia barriers and immunological bodily defensive mechanisms
of the skin, they can cause soft-tissue infections (SSTIs). This project explores the medicinal
properties of five plants indigenous to the western region of Saudi Arabia, with a history of
folkloric use: Aizoon canariense L. (Aizoaceae), Citrullus colocynthis (L.) Schrad.
(Cucurbitaceae), Maerua crassifolia Forssk. (Capparaceae), Rhazya stricta Decne.
(Apocynaceae), and Tribulus macropterus Boiss. (Zygophyllaceae), focusing on treating
SSTIs and chronic wounds. An additional aim was to identify compounds to treat infections
by following a bio-guided fractionation approach.
Following a field trip, the target plants were collected and identified before undergoing
methanolic extraction to yield approximately 200g of residual material. Initially, these extracts
were evaluated for their effect on immortalized human skin keratinocytes (HaCaT) cell line
proliferation, migration, and cytotoxicity through MTT, scratch wound, and flow cytometry.
Confocal microscopy (CLSM) was utilized to confirm the morphology and viability of the
cells. Antioxidant effects were determined using the acellular 1,1-Diphenyl-2-picrylhydrazyl
(DPPH) method, and a cell-based method was utilized to measure a reactive oxygen species
(ROS) level, namely hydrogen peroxide level (Hâ‚‚Oâ‚‚) in cell culture settings (ROS-Glo Hâ‚‚Oâ‚‚
assay). Antimicrobial properties were investigated by well diffusion, broth microdilution, and
direct bio-autographic methods. The ability of medicinal plants to inhibit and eradicate
bacterial biofilm was investigated by crystal violet and Live/Dead microbial viability method
using CLSM. Plants that exhibited interesting antimicrobial activities were subjected to bioguided
fractionation with liquid-liquid partitioning and column chromatography to identify and
isolate active compounds. The anti-inflammatory effects of plant extracts were evaluated by
utilising LPS-stimulated HaCaT cells to determine effects on expression of a panel of
inflammatory mediators.
Results indicated that C. colocynthis possesses cytotoxic activity with significant inhibition of
proliferation and migration of human skin keratinocytes. On the other hand, M. crassifolia
promoted the wound healing potential of HaCaT by stimulating the proliferation and
migration. A. canariense and T. macropterus demonstrated antimicrobial activity against
Gram-positive strains in planktonic and biofilm conditions. R. stricta demonstrated broadspectrum
antimicrobial properties in planktonic and biofilm conditions against Gram-positive
and negative bacterial species associated with SSTIs. The free radical scavenging data showed
that both R. stricta and M. crassifolia gave the highest capacity for scavenging the DPPH
radical with an IC50 of 335 and 448 ÎĽg/mL, respectively. In addition, R. stricta showed the
highest Hâ‚‚Oâ‚‚ scavenging activity in the cell-based antioxidant method. Bio-guided
fractionating of A. canariense and R. stricta successfully isolated Îł-linolenic acid and
v
vincadifformine; further antimicrobial investigation with broth microdilution assay revealed
these two compounds' contribution to the antimicrobial activity of the whole plant extract.
However, this approach failed to identify and isolate the antimicrobial compounds detected via
direct bio-autographic assay in T. macropterus. The anti-inflammatory investigation revealed
that a number of plant extracts can decrease the protein levels of several inflammatory
mediators. Finally, our study supports some of the documented ethnobotanical uses

Public’s perceptions of the emerging role of Cannabidiol (CBD) products
Cannabidiol (CBD) products, derived from hemp (Cannabis sativa) are becoming more popular as people seek alternative ways of managing their health; sales rose 333% in the US in 20181. The market value of CBD is estimated to be worth £1billion by 20252. The objectives were to explore the public’s perceptions and use of CBD products including where products are sourced, how knowledge is obtained and opinions on quality, safety and efficacy of CBD products. A questionnaire comprising open and closed questions was developed to consider quantitative and qualitative perspectives. An online platform, SurveyMonkey, was used to distribute the survey using social and professional networks (September - November 2019), which led to snowball sampling. A total of 596 responses were collected (63% female, 40% White-British) internationally. In total, 11% (n=66) claimed to use CBD products including oils, balm, tinctures and vapes for a range of ailments such as pain, stress and anxiety. Participants who did not personally use CBD products (n=530), 35% claimed they would like to try them, while 42% of participants knew of someone who was already using a CBD product for conditions such as arthritis and epilepsy and “generally improving quality of life”. Knowledge of CBD was commonly attributed to social media and news articles. Perception on safety and efficacy were positive with the notion of natural medicines being superior. Quality of products was associated with well-known brands or products which had a marketing authorisation; participants identified it was difficult to determine the quality of products brought online and better regulation is required. This study identifies that people continue to seek natural alternatives to supplement and maintain their health, thus the popularity of CBD continues to rise. The lack of clinical evidence to help make informed decisions about using CBD products needs to be addressed with more research
