“…The same pathway of metabolism was described for the analogue compound α-PHP ( 7 , 8 ). In the present case, the femoral blood concentration of α-PiHP was 2,377 ng/mL, which is much higher than those previously reported ( 3 , 4 ). Relative to histological analyses, whose findings revealed high-grade cerebral edema, brainstem edema, cerebellar edema and hyperemia and focal pulmonary edema and hyperemia, it clearly explains the rapid reaction of the man’s organs and his eventual sudden death.…”

“…The compound is an analogue of the psychotropic substances alpha-pyrrolidinopentiophenone (α-PVP) and alpha-pyrrolidinohexanophenone (α-PHP). Used alone and in combination with other substances, α-PiHP was the cause of serious poisoning and even death ( 3 , 4 ). The reason for overdosing can be a lack of consumer awareness regarding the composition and concentration of the product because the effect of α-PiHP after oral administration appears following a long delay (30–60 min) when compared to that of α-PHP or α-PVP (2–20 min), which may create a risk of accidental overdose and death as a consequence ( 3 ).…”

“…Hexedrone substitutions within the phenyl ring have resulted in the formation of two derivatives: 4-methylhexedrone formed by substitution at the para position with a methyl group, while the presence of a 3,4-methylenedioxy group resulted in hexylone and its analog, isohexylone, which is distinguished by a branched alkyl side chain. The same branched alkyl side chain can be found in the hexedrone analog isohexedrone, as well as in α-PiHP (4-methyl-1-phenyl-2-pyrrolidin-1-yl-pentan-1-one), which has been known since 2016 [ 97 , 98 ]. This popular derivative was the starting point for the formation of additional derivatives (Fig.…”

“…Within these effects prevail paranoia, hallucinations, agitation, and unconsciousness. Moreover, cardiac effects can be present, such as tachycardia, vasoconstriction and cardiac arrest, muscular effects such as tremors and rhabdomyolysis, or even death, as in the fatal cases mentioned above [24,25,33,34,83]. Comparing the effects on behaviour of α-PiHP and α-PHP administration, it can be deduced that both have very similar locomotor stimulant and discriminative stimulus effects [89,93,94].…”

“…The man was unresponsive to light, with highly constricted pupils, and had muscle tremors, and the screening test was positive for amphetamines. Alpha-PiHP was identified in both, but in higher concentrations in the man [33]. Wachholz et al carried out an investigation of a man's fatal poisoning with α-PiHP.…”
