CANNABIDIOL Usage And Synthesis
OverviewCannabidiol[CBD] is the main non-psychotropic component of the glandular hairs of Cannabis sativa. It displays a plethora of actions including anticonvulsive, sedative, hypnotic, antipsychotic, and anti-inflammatory and neuroprotective properties. It is a major phyto-cannabinoid, accounting for up to 40% of the Cannabis plant's extract, that binds to a wide variety of physiological targets of the endocannabinoid system within the body. Although the exact medical implications are currently being investigated, CBD has shown promise as a therapeutic and pharmaceutical drug target. In particular, CBD has shown promise as an analgesic, anticonvulsant, muscle relaxant, anxiolytic, antipsychotic and has shown neuroprotective, anti-inflammatory, and antioxidant activity, among other currently investigated uses[1, 2].
Cannabidiol was isolated from marijuana in the late 1930s, but only in the 1963 were its structure and stereochemistry first elucidated[3]. Early studies focusing on CBD pharmacology started in the 1970s, with the first relevant finding concerning its hypnotic and anticonvulsant properties, published in 1981[4]. Since then, a large body of pharmacological effects has been demonstrated, both in preclinical and in clinical studies.

Figure 1 the chemical structure of Cannabidiol;
ReceptorsSo far, two membrane receptors for cannabidiol, both coupled to G protein and named CB1 and CB2, have been identified. While CB1 receptors are mainly expressed in the central and the peripheral nervous systems, CB2 receptors have been reported to be more abundantly detected in cells of the immune system[5]. Moreover, two orphan G protein-coupled receptors, GPR119 and GPR55, possibly activated by multiple different cannabinoid ligands[6], have been recently proposed as novel cannabinoid receptors.
IndicationBeing used in combination with delta-9-tetrahydrocannabinol as the product Sativex, cannabidiol was applied for the following indications: 1) as adjunctive treatment for symptomatic relief of spasticity in adult patients with multiple sclerosis[MS] who have not responded adequately to other therapy and who demonstrate meaningful improvement during an initial trial of therapy [7]; Sativex was also given a Notice of Compliance with Conditions(NOC/c) by Health Canada for the following indications: 1) as adjunctive treatment for the symptomatic relief of neuropathic pain in adult patients with multiple sclerosis; 2) as adjunctive analgesic treatment in adult patients with advanced cancer who experience moderate to severe pain during the highest tolerated dose of strong opioid therapy for persistent background pain[7].
PharmacodynamicsThe correct use of CBD in human therapy necessarily requires basic information related to pharmacokinetics. Cannabis derivatives are usually inhaled or orally administered. Other routes, including rectal, transdermic, eye drops, aerosols and intravenous have been used in a small number of studies so that the relevance of findings is limited. Recently, it was demonstrated in rabbits that sublingual administration of a solid CBD/beta-cyclodextrin complex might provide an alternative formulation for sublingual administration[8]. The pharmacokinetics of CBD is quite complicated and in many aspects resembles that of Δ9-THC. Once taken orally, CBD bioavailability ranges between 13% and 19%, due to a marked first-pass effect, while the systemic bioavailability of inhaled CBD in a group of cannabis users was 31%(range 11– 45%). The plasma pattern was similar to that of Δ9-THC. Daily oral doses of CBD 10 mg/kg/day chronically administered resulted in mean plasma concentrations of 5.9–11.2 ng/mL[9]. CBD is rapidly distributed when intravenously administered, and easily passes the blood–brain barrier. CBD shows a prolonged elimination; its terminal half-life is about 9 h, and it is excreted preferentially in the urine, both free and as its glucuronide compound[10]. Cannabidiol impairs hepatic drug metabolism in several animal species, and inhibits mouse hepatic metabolism through the inactivation of specific cytochrome P450 belonging to the 2C and 3A subfamilies[11]. The metabolism of CBD showed biotransformation routes typically observed for cannabinoids[12]. It undergoes multiple hydroxylations, oxidations to carboxylic acids, beta-oxidation, conjugation and epoxidation[13]. Conjugation with fatty acids, first observed with Δ9- and Δ8-THC, provides a potent means of increasing the lipophilicity and, hence, tissue accumulation[14]. CBD-7-oic acid together with CBD - glucuronide represent the most abundant products of CBD metabolism detected in human urine[13]. Unlike Δ9-THC a remarkable percentage of unchanged CBD is excreted in the faeces[15].
Pharmacology Cannabinoid pharmacology is a field rapidly expanding and the therapeutic properties of cannabinoid receptor agonists include analgesia, muscle relaxation, immunosuppressant, antiinflammatory and antiallergic effects, improvement of mood, stimulation of appetite, antiemesis, lowering of intraocular pressure, bronchodilatation, neuroprotection and antineoplastic effects[16]. Despite the emerging evidence regarding therapeutic activities of CBs, their effective introduction in clinical use is still controversial and strongly limited by the unavoidable psychotropic effects exhibited by many of them. Since it was previously demonstrated that CBD binds with a low affinity to both CB1 and CB2 cannabinoid receptors, much research was aimed at recognizing CB1 and CB2 independent modes of action for this phytocannabinoid. To date, different molecular targets have been proposed. The first evidence that CBD can bind to sites different from cannabinoid receptors was offered by the observation that natural CBD and the[+]-synthetic one both stimulate the type-1 vanilloid receptor[17]. Other studies indicated that CBD also binds to 5-HT1A and such an interaction was suggested to account for the attenuation of cerebral infarction size occurring during ischemia[18] and also for its anxiolytic effect[19]. It has been also reported that CBD may behave as an allosteric modulator at μ and δ opioid receptors, even if the effects occur at very high levels of phytocannabinoid, so that this modulation cannot be expected to contribute markedly to the CBD actions exerted in vivo[20]. However, although CBD displays very low affinity for both CB1 and CB2, it has been reported recently that it can operate as a CB2 receptor inverse agonist and this may, at least in part, contribute to its widely documented antiinflammatory properties[21].
Furthermore it is commonly recognized that many CBD effects are mainly due to its antioxidant activity as first demonstrated by Hampson et al.(1998)[22] that exposed rat cortical neuron cultures to a toxic level of the excitatory neurotransmitter glutamate. On that occasion, the authors showed that CBD exerted a potent antioxidant activity, resulting in a more protective effect than either ascorbate or α-tocopherol, against glutamate-mediated neurotoxicity.
Mechanism of neuroprotective effectThe neuroprotective actions of CBD, mainly due to its antiinflammatory and antioxidant properties, have been well documented[22]. Recently, a neuroprotective mechanism of CBD has also been confirmed in a mouse model of ischemia, where CBD explicates the cerebroprotective action via a cannabinoid receptor-independent myeloperoxidase-inhibiting mechanism[23], in addition to a 5HT1A receptor action[18]. It has also been demonstrated that CBD reverses binge ethanol-induced neurotoxicity, once again, via a cannabinoid receptor independent antioxidant mechanism[24]. The potential of CBD to attenuate the excessive formation of peroxynitrites induced by glutamate also contributes to its neuroprotective effects, as demonstrated by the in vitro results pointing to the ability of CBD to induce the prevention of retinal apoptosis[25].
ToxicityCannabidiol exhibits very low toxicity in humans and in other species: the LD50 after intravenous administration to rhesus monkeys was 212 mg/kg[26]. The oral LD50 has not been established, but in 1981 Rosenkrantz showed that an oral dose of CBD 20–50 times larger than the intravenous route is required to initiate severe intoxication[26]. CBD does not cause relevant CNS alterations. Moreover, a large body of studies failed to reveal teratogenic or mutagenic effects induced by CBD[27, 28].
