Capsaicin synthetic

Pelargonic acid vanUlylamide, also known as nonivamide, is a synthetic equivalent of capsaicin (synthetic capsaicin). It is avaUable in a commercial spray product known as Cap-Tor, which is being increasingly used by UK pohce authorities and in European countries to replace CS irritant liquid sprays (BBC, 2001,2002,2004b). It is advised that the device should be aimed at the face, particularly the eyes. Most spray devices contain 0.3% PAVA in 50% ethanol with nitrogen as the propellant. The...

Synthetics. The lack of spice products to satisfy demand and the wide variation in price and availabihty have caused the manufacture of selected synthetics, chemically identical to the component in the natural spice, to replace the vital components of some spices. However, synthetic organic chemistry is not yet able to manufacture economically the many homologous piperine [94-62-2] components in black pepper or those capsaicin [404-86-4] amides in... 

Known antagonists of vanilloid receptors include capsazepine, which acts competitively but with low potency at the capsaicin binding sites (Bevan et al., 1992), iodo-RTX, which binds with high affinity (Wahl et al., 2001), the unselective antagonist ruthenium red (Amann and Maggi, 1991) and synthetic arginine-rich hexapeptides (Planells-Cases et al., 2000), which are putative channel blockers. 

Hence, in such samples, it is necessary to know the pungency of the individual capsaicinoids. Recent careful determinations of the pungency thresholds of individual capsaicinoids have shown that the two major components, capsaicin and dihydrocapsaicin, have the same pungency, while the minor related components and the synthetic compounds have only about half, or less, of their pungency (10.24) (Tables II and III).

Yeoh et al. (1995) demonstrated that chilli could protect humans against aspirin-induced gastroduodenal mucosal injury. A survey conducted by Kang et al. (1995) established the protective effect of chilli against peptic ulcer. Red pepper and natural and synthetic capsaicin in the diet significantly decreased cholesterol in the liver (Sambaiah and Satyanarayana, 1980).

The combination of these elements generates the diversity of capsaicinoids reported to date. Generally, the major constituent of the capsaicinoid soup are capsaicin (la) and its dihydroderivative (lb). Commercial capsaicin potvder is an approximately 5 1 mixture of capsaicin and dihydrocapsaicin, while analytical (>95 %) capsaicin contains mainly nonivamide as impurity. Despite its trivial name of synthetic capsaicin, nonivamide is a natural trace constituent of capsicum oleoresin, and concentration >3 % are indicative of adulteration [26]. The addition of nonivamide to capsicum oleoresin has been detected in products from both the food and the pharmaceutical markets. Some of them have been found to contain exclusively nonivamide, even though capsaicin is the only individual constituent of capsicum oleoresin to be approved by the FDA for human use [26]. 

Other capsaicinoids are available. Pelargonic acid vanillylamide (PAVA or nonivamide), shown in Figure 12.10, is a synthetic form of capsaicin. Nonivamide was first synthesized by Nelson (1919). Nonivamide was originally found to be a minor component in Capsicum annum peppers (Constant and Cordell, 1996) however, the majority of PAVA is derived from synthesis rather than extraction from natural plant sources. As a result, the composition and concentration of PAVA can remain consistent (Haber et al, 2007).

VANILLOID RECEPTOR ANTAGONISTS act at sites activated by sensory irritants, e.g. capsaicin see VANILLOID receptor agonists. Capsazepine, a synthetic compound developed out of vallinoids such as capsaicin, is a high-afflnity competitive vanilloid receptors antagonist. It is used as a pharmacological tool. There is some variation in affinity between different sites and species, suggesting receptor subtypes and species variants. Ruthenium Red also acts as an inhibitor at these sites in a non-competitive manner. 

Capsaicin is the major pungent component of Oleoresin Capsicum (OC), commonly known as pepper spray. OC is extracted from dried ripe chilli peppers and is a variable mixture of many compounds. Related irritants (capsaici-noids) present in the mixture include dihydrocap-saicin, nordihydrocapsaicin, homocapsaicin, ho-modihydrocapsaicin and nonivamide. The latter is used as a synthetic substitute for pepper spray.

The VAO-catalyzed production of vanillin is of special synthetic interest. In particular, a route starting from capsaicin that is readily available from red hot pepper has some biotechnological potential. Here, vanillylamine is obtained by hydrolysis of capsaicin using rat liver microsomes and further oxidized by VAO (Fig. 16.3-3). Furthermore, a one-pot synthesis using carboxylesterase for capsaicin hydrolysis is proposed1121. 

Tyihak et al. validated this technique using the separation of the synthetic dyes indophenol, Sudan G, and Butter Yellow. Natural products such as capsaicin from Capsicum annum and fiirocoumarins from Heracleum sphondylium have been separated by Nyirdey et al. (14).
