CB(1) cannabinoid receptor antagonism promotes remodeling and cannabinoid treatment prevents endothelial dysfunction and hypotension in rats with myocardial infarction. (1/155)1. To study the long-term effects of altered cannabinoid receptor activity on myocardial and vascular function, Wistar rats were treated with the selective CB(1) antagonist AM-251 (0.5 mg kg(-1) d(-1)), the potent synthetic cannabinoid HU-210 (50 micro g kg(-1) d(-1)) or vehicle for 12 weeks after coronary artery ligation or sham operation. 2. AM-251 further reduced the pressure-generating capacity, shifted the pressure volume curve to the right (P<0.05) and increased the left-ventricular operating volume (AM-251: 930+/-40 micro l vs control: 820+/-40 micro l vs HU-210: 790+/-50 micro l; P<0.05) in rats with large myocardial infarction (MI). 3. Left-ventricular CB(1) immunoactivity in rats 12 weeks after large MI was unaltered as compared with noninfarcted hearts. 4. Cannabinoid receptor activation through HU-210, a cannabinoid that alters cardiovascular parameters via CB(1) receptors, increased the left-ventricular end-diastolic pressure (LVEDP, P<0.05). However, it prevented the drop in left-ventricular systolic pressure (HU-210: 142+/-5 mm Hg; P<0.05 vs control: 124+/-3 mm Hg; and P<0.001 vs AM-251: 114+/-3 mm Hg) and prevented endothelial dysfunction (ED) in aortic rings of rats with large MI (P<0.05). 5. Compared with AM-251, HU-210 prevented the decline in the maximal rate of rise of left-ventricular pressure and the maximum pressure-generating ability (P<0.05). In rats with small MI, HU-210 increased cardiac index (P<0.01) and lowered the total peripheral resistance (P<0.05). 6. The study shows that during the development of congestive heart failure post-large MI, cannabinoid treatment increases LVEDP and prevents hypotension and ED. Presumed CB(1) antagonism promotes remodeling despite unchanged myocardial CB(1) expression. (+info)
Vasodilator actions of abnormal-cannabidiol in rat isolated small mesenteric artery. (2/155)1. The nonpsychoactive cannabinoid abnormal-cannabidiol (trans-4-[3-methyl-6-(1-methylethenyl)-2-cyclohexen-1-yl]-5-pentyl-1,3-benzenedio l) (abn-cbd) produced concentration-dependent relaxation of methoxamine-precontracted rat small mesenteric artery. Endothelial removal reduced abn-cbd potency six-fold without affecting the maximum relaxation. 2. In endothelium-intact vessels, abn-cbd was less potent under 60 mM KCl-induced tone and inhibited by combination of L-N(G)-nitroarginine methyl ester (L-NAME) (nitric oxide synthase inhibitor; 300 micro M), apamin (small conductance Ca(2+)-activated K(+) channels inhibitor; 50 nM) and charybdotoxin (inhibitor of intermediate conductance Ca(2+)-activated K(+) channels and large conductance Ca(2+)-activated K(+) channels BK(Ca); 50 nM). L-NAME alone or in combination with either toxin alone had little effect. 3. In intact vessels, relaxations to abn-cbd were inhibited by SR 141716A (cannabinoid receptor antagonist; 1 or 3 micro M). Concomitant addition of L-NAME, apamin and charybdotoxin had no further effect. Other cannabinoid receptor antagonists either had little (SR 144528; 1 micro M and AM 251; 1 micro M) or no effect (AM 630; 10 micro M and AM 281; 1 micro M). Inhibition of gap junctions, G(i/o) protein coupling and protein kinase A also had no effect. 4. Endothelium-independent relaxation to abn-cbd was unaffected by L-NAME, apamin plus charybdotoxin or capsaicin (10 micro M). Abn-cbd inhibited CaCl(2)-induced contractions in vessels with depleted intracellular Ca(2+) stores and stimulated with methoxamine or KCl. This was insensitive to SR 141716A (3 micro M) but greatly reduced in vessels stimulated with ionomycin (Ca(2+) ionophore; 1 micro M). 5. We conclude that abn-cbd relaxes the rat small mesenteric artery by endothelium-dependent activation of K(+) channels via SR 141716A-sensitive pathways, which do not involve CB(1) and CB(2) receptors. It also causes endothelium-independent, SR 141716A-insensitive, relaxation by inhibiting Ca(2+) entry through voltage-gated Ca(2+) channels. (+info)
Cannabinoid receptor-mediated regulation of intracellular calcium by delta(9)-tetrahydrocannabinol in resting T cells. (3/155)Cannabinoids exhibit broad immune modulating activity by targeting many cell types within the immune system, including T cells, which exhibit sensitivity, as evidenced by altered activation, proliferation, and cytokine expression. As a result of the critical role calcium plays in T cell function coupled with previous findings demonstrating disruption of the calcium-regulated transcription factor, nuclear factor of activated T cells, by cannabinoid treatment, the objective of the present investigation was to perform an initial characterization of the role of the cannabinoid receptors in the regulation of the intracellular calcium concentration ([Ca(2+)](i)) by delta(9)-tetrahydrocannabinol (delta(9)-THC) in T lymphocytes. Here, we demonstrate that delta(9)-THC robustly elevates [Ca(2+)](i) in purified murine splenic T cells and in the human peripheral blood acute lymphoid leukemia (HPB-ALL) human T cell line but only minimally elevates [Ca(2+)](i) in Jurkat E6-1 (dysfunctional cannabinoid receptor 2-expressing) human T cells. Removal of extracellular calcium severely attenuated the delta(9)-THC-mediated rise in [Ca(2+)](i) in murine splenic T cells and HPB-ALL cells. Pretreatment with cannabinoid receptor antagonists, SR144528 and/or SR141716A, led to an attenuation of delta(9)-THC-mediated elevation in [Ca(2+)](i) in splenic T cells and HPB-ALL cells but not in Jurkat E6-1 cells. Furthermore, pretreatment of HPB-ALL cells with SR144528 antagonized the small rise in [Ca(2+)](i) elicited by delta(9)-THC in the absence of extracellular calcium. These findings suggest that delta(9)-THC induces an influx of extracellular calcium in resting T cells in a cannabinoid receptor-dependent manner. (+info)
Endocannabinoid system modulates relapse to methamphetamine seeking: possible mediation by the arachidonic acid cascade. (4/155)We clarified the modulating action of the endocannabinoid system, and its possible mediation by the arachidonic acid cascade, on the reinstatement of methamphetamine (METH)-seeking behavior, using the intravenous self-administration paradigm in rats. Following 12 days of self-administration of METH, the replacement of METH with saline resulted in a gradual decrease in lever press responses (extinction). Under extinction conditions, METH-priming or re-exposure to cues previously paired with METH infusion markedly increased the responses (reinstatement of drug-seeking). The cannabinoid CB1 receptor antagonist, SR141716A, blocked this behavior. Although the cannabinoid agonist, Delta8-tetrahydrocannabinol (THC), had no effects by itself, coadministration of the agonist and METH at small doses reinstated the drug-seeking behavior. THC attenuated the effects of the reinstatement-inducing dose of METH, but enhanced the effect of cues. Either given repeatedly during the extinction or singly, 24 h before the first METH-priming or cues challenge, THC suppressed the reinstatement. In another set of experiments, we found that diclofenac, a cyclooxygenase inhibitor, also attenuated the reinstatement induced by exposure to cues or drug-priming. These results suggest that the endocannabinoid system, through possible mediation by the arachidonic acid cascade, serves as a modulator of the reinstating effects of METH-priming and cues. Extending the current view on the treatment of drug dependence, these results indicate that endocannabinoid-activating substances as well as cyclooxygenase inhibitors may be promising as antirelapse agents.

Central effects of the cannabinoid receptor agonist WIN55212-2 on respiratory and cardiovascular regulation in anaesthetised rats. (5/155)1 The primary aim was to study the central respiratory effects of cannabinoids (CB). To this end, the cannabinoid receptor agonist WIN55212-2 was injected into the cisterna magna of urethane-anaesthetised rats and changes in respiratory parameters were observed. The secondary aim was to observe the centrally elicited cardiovascular actions of WIN55212-2. Involvement of opioid mechanisms in the central effects of WIN55212-2 was also studied. 2 Intracisternal (i.c.) application of WIN55212-2 (1, 3, 10 and 30 microg kg(-1)) dose-dependently decreased the respiratory rate and minute volume. Tidal volume was slightly increased, whereas peak inspiratory flow remained unchanged. In addition, WIN55212-2 increased mean arterial pressure and the plasma noradrenaline concentration and decreased heart rate. 3 I.c. injection of WIN55212-3 (1, 3, 10 and 30 microg kg(-1)), an enantiomer of WIN55212-2 lacking affinity for cannabinoid receptors, elicited no effects. All effects of WIN55212-2 were prevented by the CB1 receptor antagonist SR141716 (2 mg kg(-1) i.v.). I.c. administration of the opioid receptor agonist DAMGO (0.1, 0.3, 1 and 3 microg kg(-1)) markedly lowered the respiratory rate, tidal volume, minute volume and peak inspiratory flow. These effects were attenuated by the opioid receptor antagonist naloxone (0.2 mg kg(-1) i.v.). In contrast, naloxone did not affect the respiratory and cardiovascular effects of i.c. administered WIN55212-2. 4 Our results show that activation of CB1 cannabinoid receptors in the brain stem depresses respiration and enhances sympathetic tone and cardiac vagal tone. Opioid mechanisms are not involved in these central cannabinoid effects. (+info)
The cannabinomimetic arachidonyl-2-chloroethylamide (ACEA) acts on capsaicin-sensitive TRPV1 receptors but not cannabinoid receptors in rat joints. (6/155)The vasoactive effects of the synthetic cannabinoid (CB) arachidonyl-2-chloroethylamide (ACEA) was tested in the knee joints of urethane-anaesthetised rats. Experiments were also performed to determine whether these vasomotor responses could be blocked by the selective CB(1) receptor antagonists AM251 (N-(piperidin-1-yl)-5-(4-iodophenyl)-1-(2,4-dichlorophenyl)-4-methyl-1H-pyrazole- 3-carboxamide) (10(-9) mol) and AM281 (1-(2,4-dichlorophenyl)-5-(4-iodophenyl)-4-methyl-N-4-morpholinyl-1H-pyrazole-3-c arboxamide) (10(-8) mol), as well as the selective CB(2) receptor antagonist AM630 (6-iodo-2-methyl-1-[2-4(morpholinyl)ethyl]-[1H-indol-3-yl](4-methoxyphenyl)methan one) (10(-8) mol). Peripheral application of ACEA (10(-14)-10(-9) mol) onto the exposed surface of the knee joint capsule caused a dose-dependent increase in synovial blood flow. The dilator action of the CB occurred within 1 min after drug administration and rapidly returned to control levels shortly thereafter. The maximal vasodilator effect of ACEA corresponded to a 30% increase in articular perfusion compared to control levels. The hyperaemic action of ACEA was not significantly altered by coadministration of AM251, AM281 or AM630 (P>0.05; two-way ANOVA). The transient receptor potential channel vanilloid receptor 1 (TRPV(1)) antagonist capsazepine (10(-6) mol) significantly reduced the vasodilator effect of ACEA on joint blood vessels (P=0.002). Furthermore, destruction of unmyelinated and thinly myelinated joint sensory nerves by capsaicin (8-methyl-N-vanillyl-6-nonenamide) treatment also attenuated ACEA responses (P<0.0005). These data clearly demonstrate a vasodilator effect of the cannabinomimetic ACEA on knee joint perfusion. Rather than a classic CB receptor pathway, ACEA exerts its vasomotor influence by acting via TRPV(1) receptors located on the terminal branches of capsaicin-sensitive afferent nerves innervating the joint.

Anandamide-induced cell death in primary neuronal cultures: role of calpain and caspase pathways. (7/155)Anandamide (arachidonoylethanolamide or AEA) is an endocannabinoid that acts at vanilloid (VR1) as well as at cannabinoid (CB1/CB2) and NMDA receptors. Here, we show that AEA, in a dose-dependent manner, causes cell death in cultured rat cortical neurons and cerebellar granule cells. Inhibition of CB1, CB2, VR1 or NMDA receptors by selective antagonists did not reduce AEA neurotoxicity. Anandamide-induced neuronal cell loss was associated with increased intracellular Ca(2+), nuclear condensation and fragmentation, decreases in mitochondrial membrane potential, translocation of cytochrome c, and upregulation of caspase-3-like activity. However, caspase-3, caspase-8 or caspase-9 inhibitors, or blockade of protein synthesis by cycloheximide did not alter anandamide-related cell death. Moreover, AEA caused cell death in caspase-3-deficient MCF-7 cell line and showed similar cytotoxic effects in caspase-9 dominant-negative, caspase-8 dominant-negative or mock-transfected SH-SY5Y neuroblastoma cells. Anandamide upregulated calpain activity in cortical neurons, as revealed by alpha-spectrin cleavage, which was attenuated by the calpain inhibitor calpastatin. Calpain inhibition significantly limited anandamide-induced neuronal loss and associated cytochrome c release. These data indicate that AEA neurotoxicity appears not to be mediated by CB1, CB2, VR1 or NMDA receptors and suggest that calpain activation, rather than intrinsic or extrinsic caspase pathways, may play a critical role in anandamide-induced cell death.

2-arachidonoylglycerol, an endogenous cannabinoid receptor ligand, induces rapid actin polymerization in HL-60 cells differentiated into macrophage-like cells. (8/155)Delta9-Tetrahydrocannabinol, a major psychoactive constituent of marijuana, interacts with specific receptors, i.e. the cannabinoid receptors, thereby eliciting a variety of pharmacological responses. To date, two types of cannabinoid receptors have been identified: the CB1 receptor, which is abundantly expressed in the nervous system, and the CB2 receptor, which is predominantly expressed in the immune system. Previously, we investigated in detail the structure-activity relationship of various cannabinoid receptor ligands and found that 2-AG (2-arachidonoylglycerol) is the most efficacious agonist. We have proposed that 2-AG is the true natural ligand for both the CB1 and CB2 receptors. Despite the potential physiological importance of 2-AG, not much information is available concerning its biological activities towards mammalian tissues and cells. In the present study, we examined the effect of 2-AG on morphology as well as the actin filament system in differentiated HL-60 cells, which express the CB2 receptor. We found that 2-AG induces rapid morphological changes such as the extension of pseudopods. We also found that it provokes a rapid actin polymerization in these cells. Actin polymerization induced by 2-AG was abolished when cells were treated with SR144528, a CB2 receptor antagonist, and pertussis toxin, suggesting that the response was mediated by the CB2 receptor and G(i/o). A phosphoinositide 3-kinase, Rho family small G-proteins and a tyrosine kinase were also suggested to be involved. Reorganization of the actin filament system is known to be indispensable for a variety of cellular events; it is possible that 2-AG plays physiologically essential roles in various inflammatory cells and immune-competent cells by inducing a rapid actin rearrangement.

Receptors, cannabinoid are a type of cell receptor that are activated by cannabinoids, which are chemical compounds found in the cannabis plant. These receptors are primarily located in the brain and central nervous system, but they are also found in other parts of the body, such as the immune system and the gastrointestinal tract. Cannabinoid receptors are classified into two main types: CB1 receptors and CB2 receptors. CB1 receptors are primarily found in the brain and are involved in the regulation of mood, memory, appetite, and pain sensation. CB2 receptors, on the other hand, are primarily found in the immune system and are involved in the regulation of inflammation and pain. Cannabinoids can bind to these receptors and trigger a variety of physiological responses, depending on the specific receptor that is activated and the location of the receptor in the body. Some of the effects of cannabinoid receptor activation include relaxation, pain relief, and changes in mood and appetite. Cannabinoid receptors have been the subject of extensive research in the medical field, and there is growing interest in the potential therapeutic uses of cannabinoids for a variety of conditions, including chronic pain, multiple sclerosis, and epilepsy. However, more research is needed to fully understand the role of cannabinoid receptors in the body and to develop safe and effective treatments that target these receptors.
The term "Receptor, Cannabinoid, CB1" refers to a specific type of protein found on the surface of certain cells in the human body. These proteins, called CB1 receptors, are activated by a class of chemicals called cannabinoids, which are found in the plant Cannabis sativa (marijuana) and in the body itself. CB1 receptors are primarily located in the brain and central nervous system, but they are also found in other parts of the body, such as the immune system, the gastrointestinal tract, and the reproductive system. When activated by cannabinoids, CB1 receptors can affect a wide range of physiological processes, including mood, pain perception, appetite, memory, and movement. In the medical field, CB1 receptors have been the subject of extensive research due to their potential therapeutic applications. For example, some studies have suggested that drugs that block CB1 receptors may be effective in treating conditions such as obesity, anxiety, and depression. On the other hand, drugs that activate CB1 receptors may be useful in treating conditions such as chronic pain, nausea, and muscle spasms. However, the use of cannabis and cannabinoid-based medications is still a controversial issue, and more research is needed to fully understand their potential benefits and risks.
The term "Receptor, Cannabinoid, CB2" refers to a specific type of protein found on the surface of certain cells in the body. These proteins, called CB2 receptors, are part of the endocannabinoid system, which plays a role in regulating a variety of physiological processes, including pain, inflammation, and immune function. CB2 receptors are primarily found in the immune system, although they are also present in other tissues, such as the brain, spinal cord, and peripheral nervous system. Activation of CB2 receptors can have a range of effects on the body, depending on the specific circumstances and the cells involved. Cannabinoids are a class of compounds that interact with CB2 receptors, including endogenous cannabinoids (which are produced by the body) and exogenous cannabinoids (which are derived from plants or other sources). Some cannabinoids, such as THC (tetrahydrocannabinol), are psychoactive and can produce the "high" associated with marijuana use. Other cannabinoids, such as cannabidiol (CBD), are non-psychoactive and have been studied for their potential therapeutic effects. In the medical field, CB2 receptors and their interactions with cannabinoids are being investigated for their potential role in treating a variety of conditions, including chronic pain, inflammation, and certain types of cancer. However, more research is needed to fully understand the mechanisms by which CB2 receptors and cannabinoids exert their effects, and to determine the optimal dosages and treatment regimens for these compounds.
Cannabinoids are a group of chemical compounds that are found in the cannabis plant, including marijuana and hemp. They interact with the body's endocannabinoid system, which plays a role in regulating various physiological processes such as pain, mood, appetite, and sleep. In the medical field, cannabinoids are being studied for their potential therapeutic effects on a variety of conditions, including chronic pain, nausea, vomiting, multiple sclerosis, epilepsy, and cancer. Some cannabinoids, such as THC (tetrahydrocannabinol) and CBD (cannabidiol), have gained significant attention in recent years due to their potential medical benefits. Cannabinoids can be administered in various forms, including smoked or vaporized cannabis, oral or sublingual sprays, capsules, and oils. However, the use of cannabinoids for medical purposes is still a relatively new field, and more research is needed to fully understand their potential benefits and risks.
Pyrazoles are a class of heterocyclic compounds that contain a five-membered ring with one nitrogen atom and two carbon atoms. They are commonly used in the medical field as pharmaceuticals and as active ingredients in various drugs. Pyrazoles have a wide range of biological activities, including anti-inflammatory, antifungal, antiviral, and antihypertensive properties. Some examples of drugs that contain pyrazoles include: 1. Metformin: A medication used to treat type 2 diabetes. 2. Etoricoxib: A nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammation. 3. Ritonavir: An antiretroviral drug used to treat HIV/AIDS. 4. Alendronate: A medication used to treat osteoporosis. 5. Cilostazol: A medication used to treat peripheral arterial disease. Pyrazoles are also used as research tools in the field of medicinal chemistry to develop new drugs with specific biological activities.
Piperidines are a class of organic compounds that contain a six-membered ring with nitrogen atoms at positions 1 and 4. They are commonly used in the pharmaceutical industry as a building block for the synthesis of a wide range of drugs, including analgesics, anti-inflammatory agents, and antihistamines. Piperidines are also found in natural products, such as alkaloids, and have been used in traditional medicine for their various therapeutic effects. In the medical field, piperidines are often used as a starting point for the development of new drugs, as they can be easily modified to produce a wide range of pharmacological activities.
Endocannabinoids are a class of naturally occurring chemical compounds that are produced by the human body and bind to the cannabinoid receptors in the brain and body. These compounds are similar in structure to the active compounds found in marijuana, known as cannabinoids. Endocannabinoids play a role in a variety of physiological processes, including pain sensation, mood regulation, appetite, and memory. They are produced and released by cells in the body in response to various stimuli, such as stress, injury, and changes in the environment. There are two main types of endocannabinoids: anandamide and 2-arachidonoylglycerol (2-AG). Anandamide is often referred to as the "bliss molecule" because it is thought to play a role in feelings of pleasure and well-being. 2-AG is another important endocannabinoid that is involved in pain regulation and other physiological processes. Endocannabinoids are also the target of the endocannabinoid system, a complex network of receptors and enzymes that is found throughout the body. The endocannabinoid system plays a role in regulating a wide range of physiological processes, and imbalances in this system have been linked to a variety of health conditions, including chronic pain, anxiety, and depression.

Receptors, drug, in the medical field refer to specific proteins or molecules on the surface or inside cells that bind to and respond to drugs or other molecules. These receptors play a crucial role in the body's response to drugs and are the target of many medications. When a drug binds to a receptor, it can activate or inhibit the receptor's function, leading to changes in cellular signaling and ultimately resulting in a therapeutic effect. There are many different types of drug receptors, including ion channels, G-protein coupled receptors, and enzyme-linked receptors, and each type of receptor has a specific role in the body's response to drugs. Understanding the properties and functions of drug receptors is essential for the development of effective and safe medications.
Dronabinol, also known as Marinol, is a synthetic cannabinoid medication that is used to treat nausea and vomiting caused by chemotherapy, as well as appetite loss in people with AIDS. It is a Schedule III controlled substance in the United States and is available only by prescription. Dronabinol is a synthetic version of the active ingredient in marijuana, delta-9-tetrahydrocannabinol (THC). It works by binding to cannabinoid receptors in the brain and body, which can help to reduce nausea and stimulate appetite.
Benzoxazines are a class of organic compounds that contain a benzene ring with an oxygen atom attached to a nitrogen atom. They are commonly used as dyes, pigments, and photoresists in various industries, including the pharmaceutical and medical fields. In the medical field, benzoxazines have been studied for their potential applications in drug discovery and development. Some benzoxazines have been shown to have anti-inflammatory, analgesic, and anti-cancer properties, making them potential candidates for the treatment of various diseases and conditions. For example, benzoxazines have been investigated as potential treatments for inflammatory bowel disease, where they have been shown to reduce inflammation and improve symptoms in animal models. They have also been studied for their potential use in the treatment of cancer, where they have been shown to inhibit the growth of cancer cells and induce apoptosis (cell death) in some cases. Overall, benzoxazines are a promising class of compounds with potential applications in the medical field, and ongoing research is exploring their potential uses in drug discovery and development.
Polyunsaturated alkamides are a class of organic compounds that contain both saturated and unsaturated carbon-carbon bonds. They are commonly found in plants, particularly in the seeds and fruits of certain plants, and are known for their potential health benefits. In the medical field, polyunsaturated alkamides have been studied for their potential anti-inflammatory and analgesic effects. Some studies have suggested that these compounds may be effective in treating conditions such as arthritis, chronic pain, and inflammatory bowel disease. One of the most well-known polyunsaturated alkamides is capsaicin, which is the compound responsible for the spicy taste of chili peppers. Capsaicin has been studied for its potential to relieve pain and reduce inflammation, and it is often used in over-the-counter pain creams and patches. Other polyunsaturated alkamides that have been studied for their potential health benefits include anandamide, which is a compound that is believed to play a role in the body's endocannabinoid system, and oleamide, which is a compound that is involved in the regulation of appetite and sleep.
Cyclohexanols are a group of organic compounds that contain a six-membered ring of carbon atoms with a hydroxyl group (-OH) attached to one of the carbon atoms. They are commonly used as solvents, intermediates in the synthesis of other chemicals, and as starting materials for the production of pharmaceuticals and other chemicals. In the medical field, cyclohexanols are used as intermediates in the synthesis of various drugs, including analgesics, anti-inflammatory agents, and antibiotics. They are also used as solvents in the preparation of pharmaceuticals and as precursors for the synthesis of other organic compounds. Some specific examples of cyclohexanols used in the medical field include: - Cyclohexanol, which is used as a solvent in the preparation of various pharmaceuticals and as a starting material for the synthesis of other organic compounds. - 2-Cyclohexen-1-ol, which is used as a starting material for the synthesis of various pharmaceuticals, including anti-inflammatory agents and analgesics. - 3-Cyclohexen-1-ol, which is used as a starting material for the synthesis of various pharmaceuticals, including anti-inflammatory agents and analgesics. It is important to note that while cyclohexanols have some potential medical applications, they can also be toxic and may cause skin irritation, respiratory irritation, and other adverse effects if not used properly. Therefore, they should be handled with care and used only under the supervision of a qualified healthcare professional.
Naphthalenes are a group of organic compounds that are composed of two benzene rings fused together. They are commonly used as insecticides and moth repellents, and have also been used in the past as a treatment for certain medical conditions such as respiratory infections and skin infections. However, the use of naphthalenes as a medical treatment is now generally discouraged due to their potential toxicity and the availability of safer alternatives. In the medical field, naphthalenes are primarily used as a research tool to study the effects of benzene ring compounds on various biological processes.
Arachidonic acid (AA) is a polyunsaturated omega-6 fatty acid that is found in the cell membranes of all living organisms. It is an essential fatty acid, meaning that it cannot be synthesized by the body and must be obtained through the diet. In the medical field, arachidonic acid is known for its role in the production of eicosanoids, a group of signaling molecules that play important roles in various physiological processes, including inflammation, blood clotting, and immune function. Eicosanoids are synthesized from arachidonic acid by enzymes called cyclooxygenases (COXs) and lipoxygenases (LOXs). Arachidonic acid is also a precursor to the synthesis of prostaglandins, which are another group of eicosanoids that have a wide range of effects on the body, including regulating blood pressure, controlling inflammation, and modulating pain and fever. In addition to its role in eicosanoid production, arachidonic acid is also important for maintaining the fluidity and integrity of cell membranes, and for regulating the activity of various enzymes and signaling molecules. Abnormal levels of arachidonic acid or disruptions in its metabolism have been linked to a number of medical conditions, including cardiovascular disease, inflammatory disorders, and neurological disorders. As a result, arachidonic acid is an important area of research in the medical field, with efforts focused on developing new treatments and therapies for these conditions.
Morpholines are a class of organic compounds that contain a six-membered ring with four carbon atoms and two nitrogen atoms. They are often used as intermediates in the synthesis of various pharmaceuticals and other chemicals. In the medical field, morpholines have been studied for their potential use as antiviral, antifungal, and anti-inflammatory agents. Some specific examples of morpholine-based drugs that have been developed for medical use include the antiviral drug ribavirin and the antipsychotic drug risperidone.
Glycerides are a type of lipid molecule that consists of a glycerol molecule bonded to three fatty acid molecules. They are an important component of cell membranes and are also found in many foods, including fats and oils. In the medical field, glycerides are often used as a measure of blood cholesterol levels, as elevated levels of triglycerides (a type of glyceride) are a risk factor for heart disease. They are also used in the production of medications, such as cholesterol-lowering drugs.
Cannabidiol (CBD) is a non-psychoactive compound found in the cannabis plant. It is one of over 100 cannabinoids that have been identified in the plant, and it is the second most abundant cannabinoid found in cannabis, after tetrahydrocannabinol (THC). CBD has gained significant attention in the medical field due to its potential therapeutic benefits. It is believed to have anti-inflammatory, analgesic, and anti-anxiety effects, and it may also have potential benefits for a range of medical conditions, including epilepsy, multiple sclerosis, anxiety disorders, and chronic pain. CBD is available in a variety of forms, including oils, tinctures, capsules, and topical creams. It is important to note that the medical use of CBD is still a relatively new field, and more research is needed to fully understand its potential therapeutic benefits and potential side effects.
Interleukin 1 Receptor Antagonist Protein (IL-1Ra) is a protein that acts as an antagonist to the Interleukin 1 (IL-1) cytokine family. IL-1 is a group of signaling molecules that play a crucial role in the immune response and inflammation. IL-1Ra binds to the IL-1 receptor and prevents IL-1 from binding to its receptor, thereby inhibiting its pro-inflammatory effects. IL-1Ra is produced by various cells in the body, including monocytes, macrophages, and fibroblasts, and is released in response to inflammation or injury.

- Comment: Naltrexone may enhance therapeutic effects of cannabinoids. (medscape.com)
- These effects were not correlated to the content of major cannabinoids such as CBD or THC, but with the presence of a complex terpenes profile. (bvsalud.org)
- Radioligand binding and GTPŒ≥S functional assays were used to investigate a novel series of peripherally limited CB1R antagonists with a diaryl-pyridazine core and a sulfonamide moiety. (nih.gov)
- Based on our preliminary in vitro and in vivo ADME data, we found many chiral antagonists with nanomolar affinity and selectivity for CB1R and functional antagonists at this receptor that may be able to cure fibrosis, diabetes, and obesity. (nih.gov)
- It has been shown that the cannabinoid-1 receptor (CB1R) is overactivated in fibrotic lung tissue of mice and humans with HPS. (nih.gov)
- In previous studies, rimonabant, a CB1R antagonist, demonstrated a modest ability to mitigate fibrosis in animal models. (nih.gov)
- However, the neuropsychiatric side effects of CB1R inhibitors, through the blockade of receptors expressed in the central nervous system (CNS), led to rimonabant being withdrawn from all clinical use. (nih.gov)
- To avoid the CNS side effects of the first-generation CB1R antagonists, MRI-1867 was designed to be restricted to the peripheral tissues and specifically excluded from the brain. (nih.gov)

- 14. Modern approaches to the development of synthetic cannabinoid receptor probes. (nih.gov)
- Through a lot of research and development on CB1 and CB2 ligands, different synthetic cannabinoid molecules with different affinities have been found. (nih.gov)
- 18. Type 1 cannabinoid receptor ligands display functional selectivity in a cell culture model of striatal medium spiny projection neurons. (nih.gov)
- and, imaging agents have been synthesized that target both transporters and receptors (e.g., [11C] RTI-121 as a selective radioligand for PET studies of the dopamine transporter). (nih.gov)
- Previous studies of alcohol dependent, opiate dependent and cocaine dependent animals during acute withdrawal have shown enhanced stress-like responses that are reversed by selective competitive corticotropin-releasing factor (CRF) antagonists. (nih.gov)
- Compounds that inhibit or block the activity of CANNABINOID RECEPTORS . (nih.gov)
- Angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), and calcium channel blockers, rather than beta-adrenergic blockers, should be considered as first-line therapy for hypertension in patients with type 2 diabetes mellitus who are obese. (medscape.com)

- 6. Evaluation of the potential of the phytocannabinoids, cannabidivarin (CBDV) and Δ(9) -tetrahydrocannabivarin (THCV), to produce CB1 receptor inverse agonism symptoms of nausea in rats. (nih.gov)
- We describe a peripheral CB 1 R antagonist (MRI-1891) highly biased toward inhibiting CB 1 R-induced β-arrestin-2 (βArr2) recruitment over G-protein activation. (nih.gov)
- Literature precedent suggests that peripheral blockade of CB1 receptors retains many metabolic benefits without causing CNS side effects and achieves positive benefits like weight loss, less insulin resistance, and better control of glucose. (nih.gov)
- The team provided the first proof of this concept using a novel peripheral CB1 antagonist in an animal model of diet-induced obesity and type 2 diabetes. (nih.gov)
- The team's research shows that peripheral CB1 antagonists have potential for treating metabolic syndrome and type 2 diabetes without causing unwanted neuropsychiatric side effects. (nih.gov)
- Therefore, we determined the effect of Delta(9)-THC and CBN, 2 plant-derived cannabinoids, on 2 key epigenetic markers of tumor promotion: inhibition of GJIC, which is essential in removing a cell from growth suppression, and activation of the ERK-MAPK pathway, which is crucial in activating the appropriate genes for mitogenesis. (nih.gov)
- Inhibition of MEK with PD98059 prevented the inhibition of GJIC by either cannabinoid, suggesting that inhibition of GJIC was MEK-dependent. (nih.gov)
- Functional interaction between opioid and cannabinoid receptors in drug self-administration have also been demonstrated. (nih.gov)
- Molecules that disrupt the CB1 receptor (CB1 antagonists) are effective not only in reducing body weight, but also in alleviating metabolic complications. (nih.gov)
- IRP researchers led by George Kunos, M.D., Ph.D. , hypothesized that CB1 antagonists with limited brain penetrance may retain their metabolic efficacy without the unwanted neuropsychiatric effect. (nih.gov)
