PCPr is an arylcyclohexylamine dissociative anesthetic drug with hallucinogenic and stimulant effects. It is around the same potency as phencyclidine, although slightly less potent than the ethyl homologue eticyclidine, and has reportedly been sold as a designer drug in Germany and other European countries since the late 1990s. Several other related derivatives have also been encountered, with the n-propyl group of PCPr replaced by a 2-methoxyethyl, 2-ethoxyethyl or 3-methoxypropyl group to form PCMEA, PCEEA and PCMPA respectively.
The Communist Party of Puerto Rico (Spanish: Partido Comunista de Puerto Rico, PCPR) is a communist party in Puerto Rico. The party was founded in 2010, after members reformed a previous organization called "Refundación Comunista". It operates a political training school called "Escuela Vladimir Lenin", that brings proletarian political education to schools, universities, and workers' councils. A similar effort, the "Escuela Manuel Francisco Rojas", was created online to reach an ever-growing group of people connected to the web and social networks. It also publishes Abayarde Rojo, a weekly periodical that is directed to tackling the reality of Puerto Rico and class struggle.
Methoxpropamine (MXPr, 2-Oxo-3'-methoxy-PCPr) is a dissociative anesthetic drug of the arylcyclohexylamine class and NMDA receptor antagonist that is closely related to substances such as methoxetamine and PCPr. It has been sold online as a designer drug, first being identified in Denmark in October 2019, and is illegal in Finland.
2-FXPr (2'-fluoro-2-oxo-PCPr) is a designer drug from the arylcyclohexylamine family, which is believed to have dissociative effects. It has reportedly been sold over the internet since 2025. No pharmacological studies have yet been reported, but it is closely related to known compounds such as 2-Fluorodeschloroketamine and methoxpropamine.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
