Cannabinoid As Potential Aromatase Inhibitor Through Molecular Modeling and Screening for Anti-Cancer Activity
Cannabinoid as Potential Aromatase Inhibitor Through Molecular Modeling and Screening for Anti-Cancer Activity Sudipta Baroi1, Achintya Saha2, Ritesh Bachar3 and Sitesh C Bachar4 1Department of Pharmaceutical Technology, Faculty of Pharmacy, University of Dhaka Dhaka-1000, Bangladesh 2Department of Chemical Technology, Pharmaceutical & Fine Chemical Technology Division University of Calcutta, India 3Department of Pharmacy, School of Science and Engineering, University of Information Technology and Sciences (UITS), Dhaka-1212, Bangladesh 4Department of Pharmacy, Faculty of Pharmacy, University of Dhaka, Dhaka-1000, Bangladesh (Received: April 15, 2020; Accepted: June 2, 2020; Published (web): June 28, 2020) ABSTRACT: Inhibition of aromatase (CYTP450), a key enzyme in the estrogen biosynthesis, could result in regression of estrogen-dependent tumors and even prevent the promotion of breast cancer. The present research has been designed for searching a potent chemical moiety from natural sources to inhibit aromatase enzyme, the over- functionality of which causes the breast cancer. Cannabis sativa contains a very much promising group of cannabinoids with more than 66 compounds with reported anticancer property and for the search of a target specific potent aromatase inhibitor, 61 cannabinoids from C. sativa were selected. The Structures Data File (SDF) of these ligand molecules were subjected to docking studies at the binding site of aromatase X-ray crystallographic structure based on lower resolution of the protein crystal structure and higher docking accuracy, predicted by calculating the correlation between experimental activities and Glide dock scores and compared with the standard aromatase ligand androstenedione and aromatase inhibitor fadrozole with existing drug for breast cancer treatment. The best docked pose of each ligand was selected on the basis of the highest dock score related to the binding free energies of the internal dataset compounds as compared to their observed activities. -

Clinical Pharmacokinetics of Cannabinoids Franjo Grotenhermen ABSTRACT. Absorption and metabolism of tetrahydrocannabinol (THC) vary as a function of route of administration. Pulmonary assimilation of in- haled THC causes a maximum plasma concentration within minutes, while psychotropic effects start within seconds to a few minutes, reach a maxi- mum after 15 to 30 minutes, and taper off within 2 to 3 hours. Following oral ingestion, psychotropic effects set in with a delay of 30 to 90 minutes, reach their maximum after 2 to 3 hours, and last for about 4 to 12 hours, de- pending on dose and specific effect. The initial volume of distribution of THC is small for a lipophilic drug, equivalent to the plasma volume of about 2.5-3 L, reflecting high protein binding of 95-99%. The steady state volume of distribution has been esti- mated to be about 100 times larger, in the range of about 3.5 L per kg of body weight. The lipophility of THC with high binding to tissue and in par- ticular to fat, the major long-term storage site, causes a change of distribu- tion pattern over time. Only about 1% of THC administered IV is found in the brain at the time of peak psychoactivity. THC crosses the placenta and small amounts penetrate into the breast milk. Metabolism of THC occurs mainly in the liver by microsomal hydroxylation and oxidation catalyzed by enzymes of the cytochrome P-450 complex. In man, the C-11 carbon is the major site attacked. Hydroxylation results in 11-hydroxy-THC (11-OH-THC) and further oxi- dation to 11-nor-9-carboxy-THC (THC-COOH), which may be glucuronated to THC-COOH beta-glucuronide. -
High-Throughput Analysis of Cannabinoids by LC-UV
Featured Application: Cannabinoid Profiles on Raptor ARC-18 High-Throughput Analysis of Cannabinoids by LC-UV • Increase sample throughput with this fast, 9-minute analysis. • Baseline separation of 16 cannabinoids provides more accurate and comprehensive potency and profile data. • Simple, isocratic method is more easily transferable between instruments and labs than gradient methods. As the cannabis market grows, interest in more detailed analysis of cannabinoid profiles is expanding because more comprehensive data can be used for strain identification as well as to ensure more accurate potency testing. More than 100 cannabinoids have been isolated from cannabis to date, and these compounds can interfere with the five most commonly analyzed cannabinoids: tetrahydrocannabinol (THC), delta-9-tetra- hydrocannabinolic acid A (THCA), cannabidiol (CBD), cannabidiolic acid (CBDA), and cannabinol (CBN). The LC-UV method shown here uses a Raptor ARC-18 column to fully resolve 16 major and most frequently observed minor cannabinoids for which commercial standards are available. Baseline separation ensures positive identification and accurate quantitation. As shown, all compounds were resolved in a fast 9-minute analysis, making this method suitable for high-throughput cannabis testing labs. In addition, this analysis uses a simple isocratic mobile phase so it is more easily transferable between instruments, compared to more complex methods that incorporate atypical mobile phase gradients or additives.

Medical Marijuana: High Expectations
Medical Marijuana: High Expectations Dr. Ally Dering-Anderson, RP University of Nebraska College of Pharmacy August 2019 What we know What we don’t Speaker Contact Information Dr. Ally Dering-Anderson, RP Clinical Associate Professor of Pharmacy University of Nebraska College of Pharmacy 986145 Medical Center College of Pharmacy Department of Pharmacy Practice Omaha, NE 68198-6145 [email protected] Speaker Disclosures Dr. Ally is on the faculty of the University of Nebraska College of Pharmacy Department of Pharmacy Practice She is the Senior Partner of BBfN, a health and safety consulting company She has no conflict in regard to medical use of cannabinoids “Off Label Use” In order to assure that there are no problems with the accreditation of this program nor problems caused for the accrediting body here goes: There are 3 approved products containing one or more chemicals found in the marijuana plant. Epidiolex (cannabidiol) Marinol Cesamet We will NOT discuss uses for these 3 approved products beyond the labeling. We will discuss cannabinoids not found in drug products currently approved by the FDA. The concept of being “off label” for these products is illogical, as there is no label to follow. Got it? Bibliography: #’s 1, 2, 3 A note from the CE clinical reviewers … “Medical marijuana is considered a controversial topic in CME. When a CME activity includes information about an approach to diagnosis or treatment that is not generally accepted, it is allowable to facilitate debate and discussion about the approach, but it is not allowable to advocate for the test or treatment, or teach clinicians how or when to use it.” Trust me, I am not advocating for any test - - in fact, I’m going to slam one. -
Recent Developments in Cannabis Chemistry
Recent Developments in Cannabis Chemistry BY ALEXANDER T. SHULGIN, Ph.D. The marijuana plant Cannabis sativa contains a bewildering Introduction array of organic chemicals. As is true with other botanic species, there are representatives of almost all chemical classes present, including mono- and sesquiterpenes, carbohy- drates, aromatics, and a variety of nitrogenous compounds. Interest in the study of this plant has centered primarily on the resinous fraction, as it is this material that is invested with the pharmacological activity that is peculiar to the plant. This resin is secreted by the female plant as a protective agent during seed ripening, although it can be found as a microscopic exudate through the aerial portions of plants of either sex. The pure resin, hashish or charas, is the most potent fraction of the plant, and has served as the source material for most of the chemical studies. The family of chemicals that has been isolated from this source has been referred to as the cannabinoid group. It is unique amongst psychotropic materials from plants in that there are no alkaloids present. The fraction is totally nitro- gen-free. Rather, the set of compounds can be considered as analogs of the parent compound cannabinol (I), a fusion product of terpene and a substituted resorcinol. Beyond the scope of this present review are such questions as the distribution of these compounds within the plant, the bo- tanic variability resulting from geographic distribution, the diversity of pharmacological action assignable to the several Reprinted from Journal of Psychedelic Drugs, vol. II, no. 1, 197 1. 397 398 Marijuana: Medical Papers distinct compounds present, and the various preparations and customs of administration. -
Crosstalk Between Cannabinoid Receptors and Epidermal
CROSSTALK BETWEEN CANNABINOID RECEPTORS AND EPIDERMAL GROWTH FACTOR RECEPTOR IN NON-SMALL CELL LUNG CANCER DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By JANANI RAVI Graduate Program in Molecular, Cellular and Developmental Biology The Ohio State University 2015 Dissertation Committee: Dr. Ramesh Ganju, Advisor Dr. Kalpana Ghoshal Dr. Xianghong Zou Dr. Sujit Basu Copyright by Janani Ravi 2015 Abstract (i) The endocannabinoid anandamide (AEA), a neurotransmitter was shown to have anti- cancer effects. Fatty acid amide hydrolase (FAAH) metabolizes AEA and decreases its anti-tumorigenic activity. In this study, we have analyzed the role of FAAH inhibition in non-small cell lung cancer (NSCLC). We have shown that FAAH and CB1 receptor which is activated by AEA are expressed in lung adenocarcinoma patient samples and NSCLC cell lines A549 and H460. Since the synthetic analogue of anandamide (Met-F- AEA) did not possess significant anti-tumorigenic effects, we used Met-F-AEA in combination with FAAH inhibitor URB597 which significantly reduced EGF (epidermal growth factor)-induced proliferative and chemotactic activities in vitro when compared to anti-tumorigenic activity of Met-F-AEA alone. Further analysis of signaling mechanisms revealed that Met-F-AEA in combination with URB597 inhibits activation of EGFR and its downstream signaling ERK, AKT and NF-kB. In addition, it inhibited MMP2 secretion and stress fiber formation. We have also shown that the Met-F-AEA in combination with URB597 induces G0/G1 cell cycle arrest by downregulating cyclin D1 and CDK4 expressions, ultimately leading to apoptosis via activation of caspase-9 and PARP. -

We report sixteen phytocannabinoids: cannabidiol (CBD), cannabidiolic acid (CBDA), cannabinol (CBN), cannabichromene (CBC), cannabigerol (CBG), cannabicyclol (CBL), cannabivarin (CBV), cannabidivarin (CBDV), cannabichromevarin (CBCV), cannabigerovarin (CBGV), cannabinodiol (CBDL), cannabielsoin (CBE), cannabitriol (CBT), Δ9-tetrahydrocannabinol (Δ9-THC), Δ9-tetrahydrocannabivarin (Δ9-THCV), and Δ8-tetrahydrocannabinol (Δ8-THC). All chemical structures and properties were obtained from PubChem Compound, National Center for Biotechnology Information, U.S. National Library of Medicine. Molinspiration was used for the calculation of molecular properties and bioactivity score. The parameters were molecular weight (MW), number of hydrogen acceptor (HBA), number of hydrogen donor (HBD), partition coefficient (cLogP), polar surface area (PSA) and number of rotatable bonds (NROTB). We predicted bioactivity scores for G Protein-Coupled Receptors (GPCR) ligand, ion channel modulator, kinase inhibitor, nuclear receptor ligand, protease inhibitor and enzyme inhibitor. Lipinski’s rule was used as reference to determine the drug-like properties of the phytocannabinoids. All compounds have MW<500, HBA<10, HBD<5, TPSA<140Å2 and NRTOB<10. Bioactivity score showed an active or moderately active in all compounds. -
The Use of Cannabinoids in Animals and Therapeutic Implications for Veterinary Medicine: a Review

Sulcova2, P. Gbelec3 1Faculty of Medicine, Masaryk University, Brno, Czech Republic 2Central European Institute of Technology, Masaryk University, Brno, Czech Republic 3Veterinary Hospital and Ambulance AA Vet, Prague, Czech Republic ABSTRACT: Cannabinoids/medical marijuana and their possible therapeutic use have received increased atten- tion in human medicine during the last years. This increased attention is also an issue for veterinarians because particularly companion animal owners now show an increased interest in the use of these compounds in veteri- nary medicine. This review sets out to comprehensively summarise well known facts concerning properties of cannabinoids, their mechanisms of action, role of cannabinoid receptors and their classification. It outlines the main pharmacological effects of cannabinoids in laboratory rodents and it also discusses examples of possible beneficial use in other animal species (ferrets, cats, dogs, monkeys) that have been reported in the scientific lit- erature. Finally, the article deals with the prospective use of cannabinoids in veterinary medicine. We have not intended to review the topic of cannabinoids in an exhaustive manner; rather, our aim was to provide both the scientific community and clinical veterinarians with a brief, concise and understandable overview of the use of cannabinoids in veterinary -
