Morphine (21a) was first isolated by Sertumer in 1806, followed by codeine (21b) in 1832 by Robiquet and then the non-morphine alkaloid, papaverine by Merck in 1848, all from crude opium preparations. With the invention of the hypodermic needle and the availability of the purified alkaloids, the benefits and problems associated with these compounds (and their synthetic derivative, heroin) rapidly became apparent, leading to the search for potent dmgs without the abuse potential of the morphinoids. With the exception of the semi-synthetic compound, buprenorphine (22), which is approximately 25-50 times more potent than morphine and has a lower addiction potential, none of the compounds made to date from modifications around the phenanthrene stmcture of morphine have exceeded the pain control properties without a concomitant addiction potential. An interesting compound, whose structure is based on that of morphine is pentazocine (Talwin ) (23). This has about 30% of the efficacy of morphine, but has a much lower incidence of abuse and does in fact cause withdrawal...
