Chemistry:3C-FP

From HandWiki

3C-FP, also known as 4-(3-fluoropropoxy)-3,5-dimethoxyamphetamine or as α-methylfluoroproscaline (3C-fluoroproscaline), is a psychedelic drug of the phenethylamine, amphetamine, and 3C families related to TMA (3,4,5-TMA).[1][2][3][4] It is the amphetamine (α-methyl) derivative of fluoroproscaline (FP).[1][3][4]

According to Daniel Trachsel, 3C-FP's dose is 25 mg or more orally and its duration is approximately 8 hours.[1] The specific effects of 3C-FP were not described.[1]

The receptor interactions of 3C-FP have been studied.[4][3] It shows affinity for the serotonin 5-HT2A and 5-HT2C receptors (Ki = 2,600–4,581 nM and 4,400 nM) and is a potent partial agonist of the serotonin 5-HT2A receptor (EC50 = 57 nM; Emax = 62%) but not of the serotonin 5-HT2B receptor (EC50 = >10,000 nM).[4][3]

The chemical synthesis of 3C-FP has been described.[2]

3C-FP was first described in the scientific literature by Trachsel in 2002.[2] Subsequently, its pharmacology as well as its properties in humans were reported by Trachsel and colleagues in 2012,[3] 2013,[1] and 2021.[4]

"A series of 4-fluoroalkoxy analogs of 3,4,5-trimethoxyamphetamine (TMA, 12: 100–200 mg, 6–8 h[3]) has also been investigated (Figure 6, A).[86] The influence of fluorine introduction could not yet fully be determined, as at present too little biological data of either the non-fluorinated derivatives (85[3] and compounds described in Trachsel[86]) or the fluoro analogs 84 and 86–89 is available. For some fluorinated 3,4,5-substituted compounds some volunteers reported skin itching during experiments. Whether this might point towards the involvement of other targets, such as the histamine receptors, remains to be seen. [...] Some effects upon a-methyl introduction into the 3,4,5-series could also be observed. Among the very limited data so far, a slight increase of affinities for the a-methyl derivatives over their counterparts could be suggested at the 5-HT2A receptor (Table 2; s. pairs 72/84; 76/86; 77/87; 80/89).".
