Examples of alkane isomers of C9H20, 1.1.9 [1][22], Bupropion was invented by Nariman Mehta, who worked at Burroughs Wellcome, in 1969. Note that in some cases, the resolved 3D model is only an approach of the real molecule, this means you have to execute an Energy minimization in order to do reliable measurements. [133] There have been a number of anecdotal and case-study reports of bupropion abuse, but the bulk of evidence indicates that the subjective effects of bupropion when taken orally are markedly different from those of addictive stimulants such as cocaine or amphetamine.
