I know that "research chemicals" aren't very popular on the English forums like they are in French forums, however this seems to be a relatively new chemical, related to both chemicals, MDPV and a-PPP.

Anyways anyone have any remarks on this new chemical in terms of the structure of it? I know one can't tell effects from the structure, however is there anything that can be told about it in general?
(Not sure if I made sense, try and decipher!)
 
Not very information on this RC...

From Drugs Forum:

R,S-3',4'-Methylenedioxy-alpha-pyrrolidinopropiophenone (MDPPP) is a new designer drug with assumed amphetamine-like effects, which has appeared on the illicit drug market. The aim of this study was to identify the MDPPP metabolites using solid-phase extraction, ethylation or acetylation as well as to develop a toxicological detection procedure in urine using solid-phase extraction, trimethylsilylation and GC-MS. Analysis of urine samples of rats treated with MDPPP revealed that MDPPP was completely metabolized by demethylenation of the methylenedioxy group followed by partial 3'-methylation of the resulting catechol, oxidative desamination to the corresponding diketo compounds and/or hydroxylation of the pyrrolidine ring with subsequent dehydrogenation to the corresponding lactam. The hydroxy groups were found to be partly conjugated. Based on these data, MDPPP could be detected in urine via its metabolites by full-scan GC-MS using mass chromatography for screening and library search for identification by comparison of the spectra with reference spectra.

Department of Experimental and Clinical Toxicology, University of Saarland, D-66421 Bomburg (Saar), Germany.
The metabolism of 3',4'-methylenedioxy-a-pyrrolidinopropiophenone (MDPPP), a novel designer drug, to its demethylenated major metabolite 3',4'-dihydroxy-pyrrolidinopropiophenone (di-HO-PPP) was studied in pooled human liver microsomes (HLM) and in cDNA-expressed human hepatic cytochrome P450 (CYP) enzymes. CYP2C19 catalysed the demethylenation with apparent Km and Vmax values of 120.0+/-13.4 microM and 3.2+/-0.1 pmol/min/pmol CYP, respectively (mean+/-standard deviation). CYP2D6 catalysed the demethylenation with apparent Km and Vmax values of 13.5+/-1.5 microM and 1.3+/-0.1 pmol/min/pmol CYP, respectively. HLM exhibited a clear biphasic profile with an apparent Km,1 value of 7.6+/-9.0 and a Vmax,1 value of 11.1+/-3.6 pmol/min/mg protein, respectively. Percentages of intrinsic clearances of MDPPP by specific CYPs were calculated using the relative activity factor (RAF) approach with (S)-mephenytoin-4'-hydroxylation or bufuralol-1'-hydroxylation as index reactions for CYP2C19 or CYP2D6, respectively. MDPPP, di-HO-PPP and the standard 4'-methyl-pyrrolidinohexanophenone (MPHP) were separated and analysed by liquid chromatography-mass spectrometry in the selected-ion monitoring (SIM) mode. The CYP2D6-specific chemical inhibitor quinidine (3 microM) significantly (p<0.001) inhibited di-HO-PPP formation by 75.8%+/-1.7% (mean+/-standard error of the mean) in incubation mixtures with HLM and 2 microM MDPPP. It can be concluded from the data obtained from kinetic and inhibition studies that polymorphically expressed CYP2D6 and CYP2C19 are almost equally responsible for MDPPP demethylenation.

EDIT: You know one thing now...you can potentate MDPPP with grapefruit juice :)
 
There was an Experience Report on either BL or DF but for SOME reason it got deleted/vanished.
 
Haupt***** carries it if you are interested it's $40/gram roughly.
 
mdppp is like mdpv with out any of the fun.
Its odd. I do it, I crave more like with pv, if do a ton I even get slight sexual drive but all in all mdppp is a fake mdpv a weak mdpv.
I love mdpv mdppp waste time to me
